slow-roasted sweet potatoes

I have been obsessed with the Argentinian chef Francis Mallman since I saw his of Chef’s Table episode in 2015. Sure, about the only thing we have in common is a desire to set food on fire, you know, artfully. He does so these days to great acclaim on his private Patagonian island (and 8 other restaurants around the world), accessible through two flights, a five-hour drive, and then 90-minute raft across a lake. I live on a busy block of a crowded city accessible by nearly every format of public transportation, and do so to moderate acclaim (relative mostly to how well the patrons slept that day) under a wispy-by-design gas broiler.

A few weeks ago, my obsession led us to a restaurant named Mettā in Fort Greene, Brooklyn, where everything is either cooked or finished over an open fire (if you go, do so on a cold night and sit at the counter, you’ll be glad you did) where the chef is protégé of Mallman. On the dessert menu is a highly regarded ash-roasted sweet potato with an infused whipped cream* and while it was delicious, forgive me, I didn’t have the Moment with it that every other restaurant reviewer has, but still tucked it away in my head as something I wanted to get back to soon. I just didn’t expect it to be exactly two days later, when I spotted a slow-roasted and charred sweet potato recipe from Michael Solomonov in Saveur. Obviously — because a jump from Patagonia to Fort Greene and then Solomonov is the very definition of “obvious” — it was fate.

Let me make no claims to the weekday appeal of this dish. It may not even have weekend appeal. I totally understand if you might find clearing nearly 3 hours just to cook a potato about as easy as buying a private Patagonian island. I only want you to promise that when you can, you will.

Here’s what happens when you rub a sweet potato with a generous amount of salt and pepper and bake it in a 275-degree oven for 2 1/2 hours and then finish it under the broiler: the flesh of the sweet potato gets sweeter, louder, and more nuanced than seems possible and the salty, lightly blackened skin gets so crispy, you’re going to immediately retroactively resent all of the sweet potatoes you had before then for not tasting like this.

But also: So, you know that only-in-America Thanksgiving sweet potato casserole with the marshmallows on top? Well, I’m about to go there. I’m about to tell you that the two things people (not me no never, how could you even suggest!) like it about it — even-sweeter sweet potatoes and a toasty, charred finish — are exactly why this dish is so good, but it gets there naturally over 150 minutes. You can use or discard this information as you wish.

slow-roasted sweet potatoes

* that had us reminiscing about the time we went to this restaurant in Paris where we were told by a friend to “order the Corleone and don’t ask what it is” and it turned out to a candied eggplant confit with orange zest and cinnamon and ricotta ice cream that was unforgettable enough that I bring it up here, 10 years later.

Slow-Roasted Sweet Potatoes

The first time we made these, I finished them with a sizzling toasted spice oil — basically a tadka or chaunk in Indian cooking — with a dollop of lightly salted, lemony yogurt and a little pile of black lentils on the side. It was amazing, but I almost felt like the sweet potato itself is so good, it deserves to be the whole story here. The second time, I couldn’t resist making a roasted garlic yogurt sauce and we finished the potatoes with pats of salted butter and I about wept from how good it was, so do know that this needs no bells and whistles to be worthy of your plate’s best real estate. We also had a red cabbage salad on the side that we barely remember, but this one would do nicely.

  • 4 medium sweet potatoes (about 3 pounds), scrubbed clean
  • 4 teaspoons olive oil
  • 2 teaspoons kosher salt
  • 1 teaspoon freshly ground black pepper

Heat your oven to 275°F. Arrange sweet potatoes on a large, foil-lined baking sheet. Rub each with 1 teaspoon olive oil, 1/2 teaspoon salt (which will make a quite salty skin, use less if desired) and 1/4 teaspoon pepper until well coated. Bake until very soft inside and caramelized on the bottom, about 2 1/2 hours. Heat your broiler and run the potatoes underneath it — mine is fairly weak, and this took 5 to 10 minutes, but check in regularly, a more robust one might do it in 1 to 2 minutes — until lightly charred on top. Let potatoes cool 10 minutes, then gently crush potatoes with your hands to expose the flesh; season with salt and finish with butter, or a topping of your choice. Some more ideas:

Slow-Roasted Sweet Potatoes with Sizzling Spices: For each potato, heat 2 to 3 teaspoons of a neutral oil or ghee (not vegan, of course) over medium-high heat, add 1/2 teaspoon cumin seeds and 1/2 teaspoon yellow or brown mustard seeds; fry until they crackle and pop, about 20 to 30 seconds. Add 1/2 teaspoon chopped garlic and red pepper flakes to taste; fry another 15 seconds. Pour immediately over exposed potato flesh, and finish with salt. We ate this with some yogurt that had been salted and mixed with lemon juice, and some black lentils on the side.

Slow-Roasted Sweet Potatoes with Roasted Garlic Yogurt (not vegan, of course): Cut a head of garlic in half crosswise; drizzle exposed garlic with a little oil or butter and a pinch of salt. “Close” the garlic again and wrap the head tightly in foil. Place on baking sheet with potatoes. When potatoes are done, use a knife point to remove very soft and lightly browned garlic cloves from their paper shells and mash them with a fork in a small bowl. Stir in 1/2 cup plain yogurt, or more to taste. Season well with salt and pepper. We put pats of salted butter on the exposed potato flesh and dolloped this on top.

    This sounds perfect for those sweet potatoes I have languishing in my pantry! Do you think they would re-heat well? I was thinking I could roast them one night, but then have them ready for dinner after work the next. Maybe skip the broiling and use that to warm them up?

            1. Laura

              Same question! If I’m doing these it needs to be wary in the day or the previous day, need my oven for the other items, but not quite sure when to broiler, how long to reheat

    1. Helen

      I top mine with fried garlic, spinach and chickpeas then serve with a tahini lemon drizzle. It’s so good! But I agree, just a knob of butter is just as good.

    2. Helen

      Also completely wonderful served cold and diced in a simple salad of baby spinach, feta and toasted pecans with honey/lemon dressing. I would eat sweet potato every day if I could but the family would get bored!

  2. Good lord, that candied eggplant confit sounds glorious! Mario Batali (are we allowed to talk about his recipes anymore? I have no idea) has a confit eggplant recipe with orange zest in one of his cookbooks that I bookmarked years ago and finally did and was not into it, but wow, that sounds good.

    Will definitely try these with my pounds of sweet potatoes from the Winter CSA. The last thing we did was get out the deep fryer and potato slicer we bought in Belgium for Sunday’s Super Bowl. This sounds loads easier. Thank you!

  3. pixelhammer

    Ok so now I must quit reading and dash off to the grocery store to buy sweet potatoes. Will this be efficient? No. But it does sound essential. Back in a few…..

  4. Susan

    I love slow roasted Idaho potatoes, so will definitely try this. I’m more savory than sweet eating, so use goat cheese on sweet potatoes. Looking forward to trying that on these.

  5. After seeing your Instagram story yesterday (or earlier this week? I forget) I had this sneaking suspicion I’d need sweet potatoes on hand for this. We’re living in the magical future folks!

  6. hyw2as

    This is so hilarious – I literally made a big batch of whole roasted sweet potato with a yogurt sauce (based off the miso-tahini sauce you use in the broccoli and sweet potato grain bowl). And then what do I find when I go to check your site? You’ve had the same idea! Only almost certainly done it better than I did! Haha ahh well, great minds think alike :P

    I can recommend stirring harissa into the yogurt, which is delicious, and also I have made a big batch of these and of the yogurt, and will be working through them for breakfast.

  7. Meredith

    This sounds amazing!!! We are currently on the Whole30 diet and WE CAN EAT THIS! I’m so excited. Question, what are your thoughts on eating the skins? I think the skin is kinda delicious but all recipes call for peeling (other than when eating them whole). We made a mash for shepherds pie last night (yum btw) and kept them unpeeled. I feel there are a lot of vitamins and nutrients packed in there that just get tossed. Would love to hear your thoughts. Thanks!

    1. deb

      I had literally never heard of not eating sweet potato skin until the comment section on this post on Instagram! We always eat it — it’s fantastic.

  8. Nancy

    Being Asian, we often have sweet potatoes. I like purchasing the small tiny japanese style ones and keeping them in my pantry. When I am home for an extended time, I like to just pop a few of them in the toaster oven (save the energy of heating an entire oven for a few potatoes) and toast them for who knows how long until the sugars start caramelizing and oozing out of the sweet potato. I just take them to work as a small snack when I’m hungry!

    1. executrix

      Replying to this, and to the Whole30 eater, and people concerned about energy use: whenever I bake I think about other things I could put in the oven at the same time, which often includes white or sweet potatoes. If you don’t eat a lot of sugar, a plain cold baked sweet potato is a great snack that tastes like a candy bar.

  9. DJMoore

    I am working on a variation of the “only-in-America Thanksgiving sweet potato casserole with the marshmallows on top”, which includes about half a cup of brown sugar in melted butter with the juice of one lemon to help the sugar dissolve and add a nice tang.

    This sounds even better.

  10. Stu

    I live a block away from that place, and have only been once, because the crowds are too long to wait for. I guess I’ll have to go back.

  11. We are big sweet potato fans–without marshmallows or brown sugar. Just plain, often puréed, with butter. These sound amazing, but that’s par for the course here. And I learned something new–I had wondered about eating the skins (we always eat regular potato skins, but I peel sweet potatoes) and was interested to see how many people said they eat the skins. Not only a new recipe, but a new way not to waste a thing.

  12. Kim

    Can’t wait to try this AND eat the skins. I love sweet potatoes but have never eaten the skins, although I rarely peel any other veggie. How did I develop this bias???

    BTW, the last sentence in the fourth paragraph needs some cleaning up (“lightly blackened skin skin becomes gets so crispy”). :-)

  13. Marcia

    Just read the Esquire Article… sounds like a
    Long way to go for a bite to eat ! I think I’ll stick with you.
    I’ve got sweet potatoes and I’ve got time.

  14. terri

    that is so, so yummy, and good with a butternut squash thrown in there for good measure, to mix it all into a soup later *swoon*
    Blasphemy alert– the other thing that’s super yummy is to throw it all in with a heavily salted chicken, roast it all at 450 and it turns into this gooey, yammy, chickeny love fest.
    Sweet potatoes are good no matter what!
    Thanks for the love you always show here :)

      1. Sophia F.

        Hi Deb and Dana,
        I’ve made this both ways, pricked and unpricked, and personally I preferred pricked – when I did not prick my potatoes, the skin didn’t split to really release steam, and my potatoes ended up delicious but very, very moist/soggy, with a less concentrated flavor. The pricked potatoes were a knockout. Just my two cents, I’m sure it’s very oven/potato specific :)

        1. Sophia F.

          Addendum – this could also be because I’m feeding two little kids and put on a LOT less salt, which probably helps draw out the steam.

  15. Mimi

    Love this! For one more variation ;
    After baking, I make a spicy , buttery sauce.
    Combine 3 tablespoons of butter
    1 tablespoon water
    1 heaping tablespoon brown sugar
    1 teaspoon Chinese 5 spice
    1/2 teaspoon cayenne

    Adjust this to taste !
    In a small pan , over medium heat bring to a simmer, it will come together and thicken a bit, pour over split sweet potatoes and add salt as needed. Better than marshmallows on top!
    Can’t wait to add the broiler at the end!

    1. deb

      Couldn’t hurt to try. I wouldn’t expect the skin to be so crisp because it hasn’t had enough time to really dry out, but the flesh might have a similar loveliness.

      1. Emily

        I often cook sweet potatoes in the slow cooker and I like the results, but then I love sweet potatoes pretty much any way you can make them. They come out of the slow cooker very wet though, so I think it would produce an entirely different result than roasting them.

  16. I love a variation of this from a local restaurant, where the topping is a whipped cream cheese, mixed with smoked mackerel and tiny specks of chives. MY GOODNESSS.

  17. Nicole

    Ugh I hated that episode of Chef’s Table. To me Mallman came across as a womanizer and incredibly self indulgent and wasteful. I felt bad for his partner that seemed to just be waiting around for him to stop by when it tickled his fancy to spend time with her and their child. And anyone who can spend that much fossil fuels to travel as an individual to a remote part of our world and inhabits this practice as a general lifestyle (I remember him bragging about how many times he flies around the world) doesn’t deserve the pristine land he occupies (and is destroying)
    ~rant over, these potatoes look nice

    1. deb

      I caught that too and the Esquire article I linked to seems to praise him even more effusively for it. (“The little girl frolicking around… turned out not to be his grandchild.” “…six children, four mothers.”) But I felt that way about a lot of the male chefs profiled; he’s the only one whose cooking I cannot get out of my head.

      1. elenak1

        Exactly Deb. I really don’t concern myself with people’s lifestyles when I watch actors, artists or chefs. If his “poor” wife languishes around waiting for his fancy to lead him to her, so be it. She can certainly fly to Buenos Aires and be done with him and be done with waiting. Her choice no? I find the way he chooses to live his life fascinating and his cooking style and food very interesting and mostly delicious in-spite of its apparent simplicity. He is certainly a “character.” I don’t want to have a relationship with him. I just want to eat his food and enjoy it. The sweet potato recipe is delightful. Thank you!

  18. Deanna

    Ugh. I can’t imagine how good these would be with some crispy sage/brown butter/Parmesan. I’ll find out tomorrow when I’ve restocked on sweet potatoes.

    Fun fact: in New Zealand, sweet potatoes are called kumera, and I was expecting domething really exotic when I ordered Kumera fries for the first time…needless to say, I was very disappointed.

  19. Charlotte in Toronto

    My mother always did her baked potatoes , regular and sweet, with crispy skin. She never oiled them before baking and the skin always came out crispy. I would always eat the soft inside of them first, then pick up the skin, slather it with butter and eat it just like that. It was my favorite part of the potato. She made me promise that I would never do that in public, lest people might think that I’m a mannerless slob, which would reflect on her. I’ve since come out of the closet with it.

    1. JuanitaD

      I ate potatoes the same way as a child! The skin slathered with butter was the best part – many times I would trade with my brothers and sisters and give them the centers and eat all the skins! Great memories.

  20. L from G

    Ottolenghi has these sweet potato wedges with lemongrass crème fraîche in “Plenty”, do you think that would also go with your sweet potatoes?
    Looking forward to trying them out soon!

  21. Kate

    I had sweet potatoes for the recipe with crispy chickpeas and yogurt, but I saw this this afternoon and rearranged my schedule so I could get home early enough to pop them in the oven. I am so happy I did – It was delicious! I made the roasted garlic yogurt and we put butter on it as suggested and it was fab. Was going to ask if they reheated well but I see you’ve already answered that – glad they do. Thanks!

  22. MR in NJ

    Roasted sweet potatoes made in advance and heated as needed are a favorite meal, especially in cold weather. Sometimes I put steamed or broiled broccoli on top, with yogurt on top of that. Have never baked them at such a low temp for so long, but sounds good and I will try it. Will a convection oven set 25 degrees lower (at 250) have the same effect in 25% less time (just under 2 hours)? Worth a shot.

  23. Bree

    I have just become a big tadka fan, thanks to the red lentils in SKED — I have made the soup twice within a week and my cubicle buddy has asked me to make some for her due to lunchtime envy — so I am VERY excited for these upgrades to my very frequent baked SPs topped with greek yogurt dinner.

  24. Jordan

    What good timing – I was already planning to bake sweet potatoes tonight! I used these directions and ended up with the sweetest and tenderest sweet potatoes I’ve ever had. Delicious!

  25. Ivy

    I made something similar yesterday based off a recipe from the Cooks Illustrated 2017 compilation

    To shorten the three hour cooking time, but still maintain the fully carmelized sugars and plush creamy texture the sweet potatoes were microwaved (I know, scandalous) until they hit an internal temperature of 200 degrees (6 to 9 minutes) then moved into a preheated 425 degree oven for an hour.

    Skins were brown and crisp but not charred (I can’t compare them to the three hour roast, I assume not as crisp). Possibly a viable shortcut if someone should ever find themselves in a sweet potato emergency (I am confident Deb’s way is best)

  26. gfy

    Would love a definitive sweet potato fry recipe. Have seen baked ones using cornstarch to enhance the crisp, etc, but never locked into a no fail system. Can you do one? Thanks so much!!

    1. She has an oven recipe which I love. The spices are spot on. I tend to cut them smaller and toast them longer because I love them crispy. They’re in my regular rotation.

  27. Clea Benson

    Thanks Deb! You are my go to for all new recipes and you never disappoint!
    If you cut the sweet potatoes in half, length wise, and bake them cut side down on a dark cookie sheet, they cook in half the time and the cut side get caramelized. Then finish with an immodest amount of butter and drizzle with Creme fraiche.

  28. Cheri

    Wow, have been roasting Japanese sweet ( light white/ yellow flesh) potatoes for several years now( they are a staple at roadside vendors in Asia, like roasted chestnuts here in the winter) and swoon over them when they come out of he oven. I always roast at 400 for 50-60 minutes, pierced skin, and they are soooo sweet and yummy, yes we eat skin and all. Kind of hard to mess with perfection but…
    I will try this method just to see the difference and report back!

  29. I have had a version of the Solo and potatoes at Abe Fisher in Philly. Only there…they we’re smoked and sliced in medallions with a sauce…I believe yogurt tahina sauce laced with Aleppo pepper. It been 18 months and I have never forgotten how lovely it was to eat those simple smokey potatoes. I might try this method with an alderwood smoked Salk on the potatoes. Thanks very much for the inspiration.

  30. Amy

    This looks so amazing – thanks for sharing. I gave my mother your cookbook for Christmas and like me, she is now a fan of your blog and cookbook.

  31. I love the simplicity of this. I cook sweet potatoes this way when I go camping and they are always the MOST AMAZING potatoes I’ve ever put into my mouth — but I have never cooked them like this at home. Can’t wait to try.

  32. Pesha

    Your photos tugged at my heart. My mother, long gone, would occasionally reminisce about coal roasted sweet potatoes sold from carts on the streets of the Bronx in the 1920s. There were drawers, with the potatoes arranged by size. They could be bought for a penny or a nickel etc. Thank you Deb.

      1. Julie

        Did you ever read the All-of-a-Kind Family books by Sydney Taylor about a Jewish family on the Lower East Side in the 19-teens? So great. One of the books had a chapter about the sisters going to the market. Roasted potatoes were definitely in it. You should read these books with your kids.

        1. Adrian

          I remember that! It was a sweet potato there, too. I asked my father if he could make them after reading it. I remember it being nice, but not the magic I expected from the book. (It wasn’t as bad as Turkish Delight, where I expected it to be amazing as I actively disliked it when I finally got a taste.)

        2. I loved those books – and well remember how well the author wrote about the smells and tastes of the market, and how precious the penny each child had to spend was.

          Deb, those books are a treasure – Jacob could certainly get the stories (although all the characters are girls), read them and then go on pilgrimage!
          Abby

        3. Shari

          YES! My sister and I devoured the All Of A Kind Family books. I remember meeting Sydney Taylor at a book event that was held annually in my school district, when I was a kid. You know, when literature/books and the arts were important part of the curricula. Julie, thank you for bringing this memory forward.

    1. Ttrockwoodttrockwood

      A few years ago i was beside myself when visiting madrid in the late fall- there were street vendors selling small roasted sweet potatoes! The vendor would just pop it open and sprinkle with salt and pepper, wrapped in a foil and paper. The skin was crisped and smokey and i was walking down the street taking bites of a whole sweet potato! Almost better than the cart with chestnuts.

  33. Kelsey

    These look amazing! My husband and I live in Japan and have been eating tons of sweet potatoes this winter. Yakiimo are a very popular winter food here- you can find them slow roasted at street carts and festivals over charcoal or cooked over campfires. Our local grocery store even roasts them in the afternoon and puts them out on a cart as people are shopping so they can have an easy side for meals that night. Defitely wish I could try this with red sweet potatoes though as Japanese ones can be so dense.

  34. Barbara

    First, thank you for the Esquire article on chef Mallman. What an interesting and eccentric man. Crazy, as well. But I love reading about people who don’t walk the straight and narrow ( as I do!) They are fascinating.
    I can’t wait to try these potatoes! Will do so soon.

  35. Glenda

    I live too far south for it to be, strictly speaking, necessary to have a heater, so on those days when the cold makes it inside, I look for an excuse to turn the oven on for hours. But not, like, shivering for an hour while I prep whatever is going into the oven. This looks perfect.

  36. Homa Botor

    I loved that episode of cooked. I’ve had the urge to cook food in open Fire since watching that episode. Haven’t fulfilled that desire but I know it’s going to happen in the near future. Can’t wait to try this recipe…love sweet potatoes. Thanks for sharing!

  37. Cathy

    This was AMAZING! I’m a student, so sitting at home for 3 hours doing work while this baked was feasible. I used japanese sweet potatoes and it came out incredibly sweet and creamy. I only added a pat of butter and it was perfect!! I will be making this all the time now.

  38. My boyfriend and I both agreed that these are the best sweet potatoes we’ve ever had (and we’ve made just about every variation under the sun).

    This is a perfect thing to do if you are going to be home for an afternoon. I was working at home yesterday afternoon, and popped them in a few hours before we wanted to have dinner. Couldn’t have been any easier! They almost taste like sweet potato pie.

  39. Rebecca

    Growing up in the south, we ate lots of baked sweet potatoes in the fall season. Lots of butter always, but try sprinkling cinnamon on with the butter. Delicious!

  40. Michby

    Thank you for a scrumptious dinner! Who woulda thunk it-this technique totally transformed and elevated our standard baked sweet potatoes

  41. Laura de la Huerta

    Thanks, Deb! This looks amazing!

    Heads up, Saveur misspelled the recipe author’s last name. It’s Solomonov. I know because he’s a restaurant legend here in Philly! If you ever make it down here, you should eat at Zahav.

    1. deb

      No kidding! I originally spelled it that way but then checked it with Saveur and said “huh, Deb, maybe it time you started pronouncing and spelling his name correctly” and spelled it out loud three times so I wouldn’t have to look it up again and … lol. I adore Zahav!

  42. Jenny M

    These potatoes were amazing just on their own. But the roasted garlic yogurt really put it over the top. I could eat that with a spoon.

  43. Adrian

    This looks amazing! I want to try it at 300F, as I have an apricot cake that’s supposed to cook for 90 minutes at 300. (Last time it took 2 hours, because I was using a metal pot to get a round cake.)

      1. Adrian

        After a recipe by Jo Walton:

        In large mixing bowl:
        2 cups flour + 1/2 cup sugar + half tsp salt
        Almost 1 pound coarsely chopped dried apricots (Open bag, take out a handful, chop the rest into raisin-sized pieces.)
        In small mixing bowl:
        1/2 cup canola oil + 1/2 cup coconut milk + 2 beaten eggs + 1 tsp orange extract

        Mix liquid + solid (obviously), and bake at 300F until it turns into cake. Then glaze with diluted apricot jam.

        As I don’t have a proper cake pan, I usually bake cakes in loaf pans, brownie pans, or cupcake tins. This time I used something I call a dutch oven (but nobody else does.) It was made by RevereWare in 1991. It’s 7.5″ round and holds 2 quarts, and it’s made of stainless steel with a layer of copper sandwiched in the base. It has 2 handles and a lid made of the same material as the pan so it can go in the oven and it’s one of the most useful things I own.

        1. Beth

          Thanks for this idea–hoping to try it later this month. I took a look at Jo Walton’s webpage; she uses self-rising flour, so I’m guessing that (scaling her recipe up from 1 cup of flour to 2 as shown by Adrian), it would take 1 tablespoon of baking powder. The amount of salt would remain the same. Similarly, I imagine JW’s 40-minute bake @300 for a loaf might scale up to the 90 minutes Adrian mentions, depending on pan used, etc.

  44. Niko

    Except for the broiling, this is the only way I make sweet potatoes 🍠. So worth the wait. Recently Cook’s Illustrated had an article about speeding up this process. I believe there was a microwave start to achieve a specific temp, and oven finish. Haven’t tried, but for the time strapped person…

    1. jjjeanie

      The other night I got home too late to bake my yams/sweet potatoes, so I gave them a white potato treatment: I sliced them about 1/2″ thick, threw them into a 9×13″ pan with a bit of olive oil, and Voila! Yummy sweets in about 30 min.

  45. Trushna

    Winter is probably the best time to keep the oven on for nearly 3 hours. Those sweet potatoes look like sunshine on a plate! Perfect for a cold, grey, snowy day here. Thanks Deb, off to stock up!

  46. Jill

    Warning…watch very carefully when under broiler…mine wound up with flames shooting out of the top of them. They were delicious though!

  47. Collette

    The best sweet potato I ever had was off the street in Beijing. A woman was carrying a pan strapped around her neck (almost like an upside down pan drum) filled with what was probably coal. Nestled inside the coal were whole sweet potatoes that she would pluck out and hand to you in a bit of foil. I was the only one in my group who purchased one but they all wanted one after they had a little bite of mine. Too bad, she was gone. Best sweet potato ever–the crispy crackly skin, the fluffy creamy flesh steaming in the cold as you pulled open the potato.

    Oh my–look what you started! I can’t wait to try this–thank you!!

  48. Steve

    I’m glad to hear I’m not the only one who was obsessed with Mallmann’s episode of Chef’s Table. His passion for food and the outdoors was very inspiring. Love the idea of slow roasting sweet potatoes! Will certainly have to give this recipe a try. :)

  49. Mary

    Wowza! These are fabulous! My house smells great as well! I made a double batch, hoping to use up this Costco bag of organic sweet potatoes, which was a good call! I topped the first potato (sampling mid-day, here!) with butter mixed with Berriyaki Sauce (River Wave Brand…. local to the USA Pacific Northwest, but maybe not?).

    Deb, did you know that you were on BBC Radio 2 today? I was listening to Simon Mayo’s ‘foodie Thursday’ show and they made pumpkin cheesecake and referenced you as the inspiration! Very exciting. It was like hearing a good friend mentioned so I had to tell you!

  51. I’m thinking I’ll bake these along with your better oven ribs. You have a rib option at 300 degrees for 2 1/2 hours. What do you think? Can the ribs and potatoes share an oven to make a whole meal that’s slow roasted?

      1. Well, that’s the best meal I’ve ever made. I put the sweet potatoes on the bottom rack and the ribs in the middle. I cooked both for 3 hours at 300 degrees and took turns broiling each for a few minutes at the end.

        I dotted the potatoes with homemade garlic rosemary butter and the experience was existential. The entire meal was so easy and hands off, and the result was something worthy of daydreams. I made a tossed salad because I thought the pork and potatoes would be heavy, but neither of us wanted to betray the flavor palette to even take a bite. And both were so tender that it didn’t feel heavy at all. The meal requires nothing in addition to the ribs and potatoes. All I can think of for these thirty minutes after I finished eating is OMG that was good. This is going in the “serve to guests and look like a rockstar” category.

        You should provide cross links in both of these recipes so others can also enjoy a 5 Star meal that you just let sit in the oven for three hours.

    1. Lynn

      I’m doing that today too! I have the spice rub ready for my ribs, and we were already going to have baked sweet potatoes with them. Now I know they’ll be unbelievable!

  52. Rosemary

    Make sure you check out Cooks’ Illustrated,(Set/Oct 2017) where they jump start the sweet potatoes in the microwave to a internal temperature of 200, then roast for an hour. They didn’t broil them but maybe a step I need to add.

  53. Novia

    Made this last night along with some oven-roasted veggies and pork tenderloin. Loved that the slow roast made the potato skins a little more palatable. I drizzled some balsamic honey reduction on top (that I made for the pork) and they were fantastic!

  54. Linda Michaluk

    Just ate one hot out of the oven… o sauces and no butter…excellent! I’m wondering about cold, later, with creme fraiche for dessert…

  55. Lizzy B

    Thanks for this recipe! After thinking about them daily since you posted, I woke up this morning with an empty schedule, a sweet potato, and no more excuses. They were amazing!!! The flesh was melt in your mouth delicious and the skin crisp and flavorful. Only wished I had some yogurt to try out the variation…next time though!

  56. katy

    i may never cook sweet potatoes the “old way” again? when you do it this way, the flavor is deep. the skin is toasty. and the flesh is wonderfully smooth. worth the wait! i was out of plain yogurt so i added roasted garlic to cheme fraiche. extreme deliciousness!

  57. dcbasebal1

    With the weather here on the East Coast this weekend, this recipe is perfect for tomorrow’s Sunday dinner! Will make my usual roast chicken not seem quite so boring! P.S. That jam band is precious!

    Hi, I just got your new cookbook yesterday. I love a good cookbook that is a good read and tells a story. Yours absolutely fills the bill. I have already tagged 35 recipes to make – a new world record! And, that doesn’t include sweets. (I’m not much of a baker.) Looking forward to cooking and the new book gets a two thumbs up from me.

  59. JP

    I had one sweet potato, so I started with Cook’s Illustrated’s advice and put it in the microwave for 6-9 minutes to bring it up to 200 degrees. Then into the oven it went because my husband was baking sourdough bread. The temperature was 425 degrees (I know, much higher than your suggestion), but in less than an hour, it was totally done and delicious. Just have to watch that the skin does not scorch because then it is too bitter to eat. Sweet potatoes are one of my very favorite foods and to get a good recipe is priceless. I would love to try your topping some day. Thanks for the inspiration!

  60. Morgan

    The sweet potatoes were delightful, but the winner winner chicken dinner here is the roasted garlic yogurt topping. That is SCRUMPTIOUS. It tasted very much like french onion dip somehow and all I wanted were some Ruffles for dipping. Thanks!

  61. MJ

    This is very nice, but it just makes me want summertime campfire sweet potatoes even more. You take sweet potatoes along on your next camping trip, rub them down in oil, wrap them up individually in foil, throw them in the campfire and let them sit there all night, then you eat them, cold, for breakfast. There is nothing better.

  62. Andrea

    We heat with a woodstove and at this time of year it is always burning. Guess where we cook the sweet potatoes. Wrapped in foil and scooted to the side of the fire box sometimes forgotten for at least a couple hours. Always melt in your mouth delicious. Move over Mr. Mallman!

  63. Yessss! I made this last year, I think, or whenever Saveur put it out there. I even tracked down the dill seeds for it, which at first felt overly fussy but then I became addicted. (They’re aces added to an everything-bagel-seasoning situation.) Thanks for the inspiration, I might make these again this week! Any excuse to run the oven for a few hours in the frozen tundra. <3

    Really really good – just made 2 of these in my Wolf toaster oven – which is where I
    do virtually all my baking/roasting. So there’s the question. In a toaster oven, for this recipe would you recommend baking or roasting – &/or at what temp. for
    either. Also, there’s a convection possibility here, which I’ve never used.And, when wondering, I usually roast, but here I did bake, to follow your directions.

  66. Brandy Barents

    Forgive me for a simple question, but what kind of sweet potatoes do you use? Our closest grocery store is Whole Foods, and I always get overwhelmed by my options. But maybe any sweet potato (or yam) would be delicious.

  67. Kristine M.

    Ok, so I made these last night. I also made a yogurt topping with plain Greek yogurt, lemon, and spices. I was licking my plate clean, and thankful that I had one left over for lunch the next day! Not so, as my husband tucked into the last sweet potato. Will be adding these to the meal rotation.

  68. Francoise

    This sounds so good. A few months ago CI published a “best oven roasted sweet potato” recipe. The writer (in the “why this recipe works” section) explains exactly why slow roasting the slices gives them such outstanding flavor. I can’t roast sweet potato slices any other way – this sounds like a similar idea but with the whole potato. I can’t wait to give it a try!

  69. NathalieHrizi

    These were so tasty. I am currently on a kick of eating roasted sweet potatoes loaded with veggies, a bit of meat and sauce for lunch. Theses brought my lunch to a whole new level :)

  70. I usually do not eat sweet potatoes. But, after reading your useful article about slow roasted sweet potatoes, I get interest to test this item. I hope I can make it soon and serve it to my friends in our next gathering.

  71. Donna M Watterson

    I love sweet potatoes with salt, pepper, butter, and fresh ground cinnamon. I will have to try putting them under the broiler.

  72. Eliza

    These are DELICIOUS! I made them with the roasted garlic yogurt sauce… but we also had them plain plain plain. Either way, so good! Thanks for another great recipe.

  73. Gail

    I’ve always baked my SPs low and slow but the revelation here for me was oiling and salting the heck out of the skins! What a great idea and delicious too.

  74. Lisa S

    About four or five times during dinner my husband remarked “This is the best sweet potato I’ve ever had.” He didn’t add anything to it, and I usually put maple cream out when we have sweet potatoes. He also tried to scrape the caramelized syrup off the baking sheet. So, I’d say, it was pretty good.

  75. harelcain

    Here’s another finish to try, you’ll thank me for it: drizzle high-quality raw tehina paste on the cut-open sweet potatoes while they’re still hot. Pure hedonsitic pleasure.

    Note that I mean the raw tehina paste, not the tehina sauce one makes out of it using lemon juice and water.

  76. I may have missed this in the comment section, so my apologies……

    How do you suggest reheating tomorrow? I have them in the oven as I type for tomorrow’s lunch….going to top with granola and yogurt!

    PS. Had slow roasted charred sweet potatoes last night in Philly at Abe Fisher (a Solomonov restaurant)….they were DIVINE.

    Thanks in advance!

  77. LC

    Thanks! We were both ‘iffy’ on sweet potatoes – until I made these slow baked sp! They are fantastic. Deeper flavor, better texture. An incredible ‘entree’ needing only a veg or salad. Really a perfect addition to our permanent menus.

  78. MYX

    What an awesome recipe Deb. I made this a couple of times and love it! The second time I added in some caramelized onions which I always love with sweet potatoes. Thank you,

  79. Priscilla

    These look lovely. I must admit I may not ever get around to making them, because throughout the colder months in my city, you will find amazing slow charcoal roasted sweet potatoes –flavoured with chaat masala and a squeeze of lime or a bit of starfruit — sold on every other street corner. Come to Delhi during its short winter and eat shikarkandi ki chaat — you’ll never think of sweet potato the same way again!

  80. Phoebe Barkan

    Two word: miso. butter

    mix 2 parts butter with 1 part miso paste and finish your sweet potatoes with it. I think it’s magical.

  81. mary

    Skin didn’t get crispy, should I have roasted them longer? They were in the oven for about 2 1/2 hours. I did broil them, is that when they are supposed to get crispy? Thank you.

  82. Loved this… and now it’s on repeat :) Instead of roasted garlic yogurt, I top it w toum… a whipped garlic and oil dip. (Or you can just buy ‘garlic dip’ in the refrigerated case at Trader Joe’s -which is slightly salty but super delicious and easy!!!)

  83. Lindsey

    Deb,

    Would these reheat well if roasted earlier in the day and then popped back in the oven to reheat before dinner?

    Thanks!

  84. Katia

    Another huge hit. Wow – amazing. Ate them with a little salt and smoked olive oil. Can’t wait to try with just plain butter or ghee.

  85. Jess

    I have a question about the safety of making a large batch of the garlic yogurt. How long will it last in the fridge and do I need to worry about botulism if I added water to thin the yogurt. I am not sure if the yogurt and water will have the same effect that oil and garlic can have.

    P.S. I made it last night and it was delicious!

  86. Diane

    We had these last night with some sautéed string beans and a riff on the crunchy pork chops from the site. I used pork tenderloin and made them more like medallions (one might say they were more like nuggets). It was easy and delicious. I made the coated pork last weekend as well so had some in the freezer. I put the potatoes in when we popped home after errands and then I went out for drinks with friends (my SO was home, so it was safe). I didn’t have time to do the other toppings but I mixed some harissa with Greek yogurt and then put butter and the harissa yogurt on top of the sweet potatoes.

  87. Anna

    First time slow-roasting sweet potatoes, or just about anything for that matter. I roast veggies multiple times per week, all year (yes, even in the summer!), and have always stuck with the high-heat method. Partly for speed, but mostly because the deep brown edges are my favorite part of anything that goes in the oven. I was excited to try this low-and-slow approach, but mine didn’t turn out as wonderful as I had hoped. The insides were fairly dry/starchy, rather than mushy/jammy/caramelized as I had imagined. This might be due to the type of sweet potato I used – can I blame the sweet potato?? These were long, skinny guys from the local farm stand, definitely a different variety than the classic “plump” ones pictured here. I’ll certainly try this again with bigger sweet potatoes and hope that solves the problem.

    Also, to add to the peel/no-peel debate: I adore roasted sweet potatoes and have always eaten the skin. It’s full of nutrients and quite tasty too! Buying organic and scrubbing well quells some of the fears about pesticides and fertilizers.

    This is a tangent to the original post, but one final note. If you must peel your sweet potatoes for a particular recipe, don’t throw the skins away!! Line a baking sheet with foil; toss the peels with olive oil, salt, pepper, and any other ground spices you like; and roast at ~400˚F until browned and crispy. Works with apple peels too! A rare chip that’s both addictive AND nutritious enough to burn all your fingers and finish the entire tray in minutes without an ounce of guilt or regret (except maybe about the burnt fingers).

  88. Molly

    Definitely my new favorite way to eat sweet potatoes. I also have always peeled them but the skins on these were delicious. Served them with butter alongside some spicy chicken sausage and broccoli but they were the star of the meal. Even did great reheated in the microwave the next day.

  89. Jackie

    I guess I’m really in the minority here but I didn’t love this. Made these with the garlic yogurt topping and it was just blah to me. I’m generally indifferent to sweet potatoes but I had a couple at home and hoped this recipe might convert me.

  90. I believe sweet potatoes are wonderful with melted butter. Some people add cinnamon to the potato also. I grew up eating sweet potatoes mashed, and with marshmallows on top. This with brown sugar was wonderful, but SWEET. I am off sweets again, so I will eat mine with butter. At times, I order a baked potato, and forget the sweet potatoes. Other times I know the sweet potato deserves our pallet.

  91. Abby Krogh

    Just followed this technique to use in sweet potato pie, and boy oh boy it’s a good thing I tossed an extra one in the oven, because I ate most of it. It’s totally worth the elapsed time. I have a feeling this will be a reallllly good pie.
