whole lemon meringue pie bars

I’ve apparently been wanting to make lemon meringue pie bars for at least eight years, as per my decade-plus log of everything I want to cook. Three different times I’ve tried to draft a recipe but I always got stuck on how much was involved, both in three separate cooking processes and eggs, just so many eggs. Whole eggs in the lemon portion, egg whites for the topping… it just felt like a lot, if not a dealbreaker, enough reason for me to pause on the idea until I had a more efficient way to approach it.

I found it in Susan Spungen’s (who you might remember from this Perfect Tarte Tatin) latest cookbook, Open Kitchen, which focuses on cooking for casual entertaining, a distant memory these days but I do love the breezy-feeling recipes here. Spungen is a recipe developer and food stylist and I know that the latter connotes images of a person moving parsley around with tweezers or using dental grip to keep a cookie in place on set, in reality, most food stylists I know arrive at work and are handed a stack of recipes that may or may not even work, which they have to cook and plate them in a very short window of time. The food stylists I know are very good cooks, skilled at cutting to the chase of a recipe. Spungen’s book benefits from this.

Spungen uses one of my favorite ways to make lemon bars (see: Whole Lemon Tart in the archives or Whole Lemon Bars in The Smitten Kitchen Cookbook) — with one whole lemon, rather than the fresh-squeezed juice of half a dozen — to make a complexly flavored lemon bar. Only yolks go into the lemon portion, and only whites in the meringue in an efficiency of ingredients and processes I found deeply soothing. The resulting bars are wildly delicious — the sweet meringue, toasted like a marshmallow, is the perfect balance for the intense lemon bar. There are still three things to prep, but I add a few shortcuts — I make my crumb crust and whole lemon curd with cold butter, and I fast-cool things in the freezer — that make it more efficient. The bars you’ll get to eat when you’re done are fully worth it.

Whole Lemon Meringue Pie Bars

Let’s talk about lemons: Spungen recommends a Meyer lemon for the whole lemon but I found in working on my own whole lemon bars that regular (Eureka) lemons were just fine so long as they’re not too large (4 to 4.5 ounces is ideal) and the skin isn’t too thick. Cut the lemon in half and take a look at the thickness of the pith (white layer) of the skin. Does it look thick to you, perhaps even 1/4-inch thick or larger? If so, go ahead and remove the skin only from one half of the lemon before proceeding. If it looks normal or not especially thick, you’ll be just fine.

  • 9 whole graham cracker sheets (1 sleeve), broken into pieces or 1 1/2 cups (150 grams) crumbs
  • 1/4 cup (50 grams) granulated sugar
  • Large pinch of salt
  • 5 tablespoons unsalted butter, cut into cubes
  • Filling
  • 1 whole (preferably organic) lemon, any variety (see Note), scrubbed
  • Juice of 1/2 lemon
  • 4 large egg yolks
  • 8 tablespoons (4 ounces or 115 grams) unsalted butter, cut into cubes
  • 1 cup (200 grams) granulated sugar
  • 1 teaspoon pure vanilla extract (optional; I skip it)
  • Pinch of salt
  • Meringue
  • 4 large egg whites
  • 1 cup (200 grams) granulated sugar
  • 1/2 teaspoon pure vanilla extract
  • Pinch of salt

Make the crust: Heat your oven to 350F [180C]. Line an 8-by-8-inch [20-by-20-cm] baking pan with two pieces of parchment trimmed to fit, going in both directions, with some extra hanging over for easy removal of the bars later.

Place the graham crackers, sugar, and salt in the bowl of a food processor and process until the fine crumbs form. Add the cold butter and pulse until the cold butter blends into the crumbs. It should look and feel like wet sand. Transfer to the prepared pan and mix it up with your hands to make sure the butter is well distributed. Press into the pan, going up the sides a bit, and bake for 10 minutes, or until just golden. Let cool while you make the filling.

Make the filling: [See Note up top for using different lemons.] Trim the stem end of the whole lemon and cut it into thin slices. Remove any seeds. Add to a food processor or blender jar (preferably a high speed blender) along with the lemon juice, egg yolks, butter, sugar, vanilla (if using), and salt and blend until very smooth, scraping down the sides as needed. Pour over the crust (it’s ok if it’s still warm) and bake for 30 minutes, or until it is bubbling and browning around the edges. It won’t look at all set, and might even look like a total mess (unevenly browned or bubbly), but it will set up as it cools. Place on a cooling rack. After about 10 minutes, run a small, sharp knife around the edges. Cool completely, then chill until coldm (I sped this up in the freezer). When completely chilled, carefully remove the parchment and, using a spatula, transfer to a small baking sheet (you can do this just before adding the topping — I missed this step and regretted it because you want the paper off before you try to toast the top or it will — whoops — burn).

Make the meringue: An hour or so before serving, make the topping. Combine the egg whites, sugar, vanilla, and salt in the metal bowl of a stand mixer and set over a pan of simmering water. Keep the mixture moving, using a whisk or the whisk attachment, until the sugar is completely melted and it’s hot to the touch (or 160F). Transfer to a stand mixer and beat on high speed until glossy and very stiff, 2 to 3 minutes. Transfer to the top of the lemon bars, smooth out, and use a large serving fork to create a pattern in the meringue, or the back of a spoon or offset spatula to make swirls like you see here.

Finish the bars: When you’re ready to finish, use a kitchen torch or your oven’s broiler to brown the meringue. Refrigerate until ready to serve. Use a knife dipped into hot water to cut bars into 12 to 16 squares, depending on how large you want them.

  1. Mimi

    These are definitely getting made this week. In the first photo, you show a stack of round cookies/crackers. Are these what you used (and if so, what are they?) or did you use regular rectangular graham crackers?

        1. Laura

          The meringue in this recipe is cooked over a double boiler before it’s spread on the bars. There are several different types of meringue, this one gets cooked while it’s being whipped.

  2. Margie S

    What if you used aluminum foil instead of parchment? I used foil to line pans for years, only recently converted to parchment.

  3. lucy

    How much do you think I could reduce the sugar in each component without making it taste horrible? Would halving each one be too aggressive?

    1. Katie

      I think you could definitely reduce the sugar in the lemon part but I’m not sure about in the meringue, since sugar has a structural purpose there.

    2. Mimi

      I made it with Splenda in the meringue and real sugar in the crust and the meringue and it turned out delicious. With that combination, each bar had 19.9 grams of sugar (I cut them into 16 pieces).

        1. Bronwyn David

          I have long thought that any recipe using only yolks or whits needs to have a corresponding recipe using the remainder. Thank you for your practicality.

    3. Ruthie

      I only used a spoonful of sugar in the crust and that was plenty. I reduced the sugar in the filling by about 20g and I think that’s all you can get away with because the lemon is quite bitter. That part is in the oven now. Will use the full amount for the meringue.

      1. Ruthie

        Update after tasting: could not have gone any lower in the sugar in the filling or it would have been too bitter. Lovely lemon flavour. I used Meyer lemons.

  4. Bentley

    Oh drool these might have to happen tonight!! Is this the only method you have found to completely eliminate the risk of weeping?

    1. Did you use a small torch, or your oven to brown the meringue? I always stop myself from making meringue because I don’t have a small torch and I don’t want to disappoint myself.

  5. Regina

    Hola! If I don’t have a food processor (and live in a country where they are difficult to find) how can I make this? It looks so good! Please help.

    1. Chelsea

      (1) For the crust, you can put the crackers in a ziplock/plastic bag and crush well before combining with the other ingredients. (Or any way of crushing cookies well and uniformly would work, I suppose). (2) For the filling, I think you either (a) want to find a lemon filling recipe that doesn’t use the lemon rinds and substitute that or (b) if you have a blender, you might be able to get away with that. (3) For the meringue, I’m pretty sure you can just use a whisk and whisk and whisk until it forms stiff peaks.

  6. Sarah

    This must be the week for lemon meringue bars because our host request for Father’s Day was lemon meringue but combined with cheesecake! I smashed together your cheesecake bars topped with Stella Parks’ lemon meringue pie recipe for a triple layer behemoth. Not that anybody complained!

      1. Sarah

        If you do, use a metal 9×13 if you have one since you’ll need to chill the pan then return it to the oven to toast the meringue. I ran the finished product under the broiler (be REALLY careful because it will burn in minutes) instead of baking it a la Parks.

  7. I’m so pleased to see this here! I got Susan’s book a couple of weeks ago and this was the very first recipe I made from it. Love these bars – they are absolutely delicious, and the recipe efficiencies just make so much sense.

    1. Renee

      Loooove this idea! Friends (for those of us who are “crust people”): what do we think of cutting down the filling & merengue for a shorter bar? Like maybe if I halve (or take a quarter off of) the filling/topping ingredients because I LOVE crust in high proportions. Thoughts?

      1. Mimi

        I think the filling level is pretty proportionate but I think you’d still get a pretty nice effect with just half the meringue.

        My suggestion, however, would be to make more crust and go higher up on the sides with it so it’s more pie-like. That way the majority of the pieces will have extra crust (like 75% if cut into 16 pieces) and their will be a few “normal” middle pieces.

        Either method would retain the integrity of the bars.

  8. Nancy

    I’m confused. In the last picture, the cross section of the bars look to be completely meringue? Does the lemon part of the bar merge in with the meringue? Or is the lemon part also a bit pale?

    1. deb

      No, it’s just from cutting them straight down, some of the meringue dragged over the filling. The meringue is much thicker than the filling, but the filling exists. They’re in the correct balance!

      1. Lauren

        I am a little confused by the step where you say to remove the parchment paper before adding the topping. How would I slide it out from under the filing without completely destroying it? Is this the old whip the tablecloth out from under the dishes trick?

        1. Angela Murray

          To determine how much to increase the original recipe to use a larger pan, use this equation
          (13 × 9)÷(8×8)=(117)÷(64)=1.8 So increase the recipe by 1.8 times. Easiest if you use grams. So if you double it, it will just be a thicker batch.

          1. Christine

            Made these to give as a birthday gift. They came out very cute but are so sweet I don’t see how anyone could eat more than a small bite. The crust and lemon curd also ended up quite soft and buttery. Hoping the will firm back up in the fridge. But wish the lemon later was more tart. Would consider eliminating sugar in the crust.

  9. Jennifer Sandman

    This looks great! Technical question: is there a difference in texture in the crust from processing the graham cracker crumbs with cold butter, rather than melting the butter and mixing it with the crumbs as I’m used to doing for a crumb crust?

  10. Fran

    Two questions:

    1. Could you share more photos/descriptive logistics as to how to handle the bowl, pan of water, and stand mixer when making the meringue? Do you use a bowl that’s shorter than the stand mixer bowl, move the stand mixer over to the stove and hold everything in place while mixing over the simmering water? And then transfer to the stand mixer bowl for the whisking/whipping stage? Or is this all easier with a hand mixer? (Sorry, that was a lot of questions in one)

    2. It would be a totally different bar, but I’m dreaming of this with a chocolate filling instead of lemon, so it’s like a s’mores bar. Would the filling from your chocolate tart recipe work?

    Thank you as always for beautiful and delicious recipes!

    1. Stacey McCullough

      Hi Fran, For 1., you’d place the stand mixer’s bowl over the pot of simmering water and whisk by hand until it’s about 160 degrees, then place that bowl back into the stand mixer for the next part. I just checked, and the first few Google Images for ‘stand mixer bowl double boiler’ show the right idea. Hope that’s helpful!

    2. deb

      Hi Fran — In a bit, I’ll share an Instagram Story demo which I can link to here and you can see how I did it. Also, I realize I didn’t add my notes in that part. I just use a handmixer. So, I beat it for a few minutes over the water, transfer the bowl to a towel, and continue beating it until it’s thick. It’s a bit more straightforward.

      I love the s’mores idea. The chocolate tart would work but I am tempted to point you to one way way way back in the archives, in this post. The filling was so rich and more ganache-ish, which feels closer to a s’more texture. Let me know if you try it. Also, btw! There’s a s’more pie in the archives too, but I think it needs some streamlining.

  11. Alene

    First, thank you for not using a lemon bar recipe with scads of eggs. We’re not getting to the store as much as we used to. And thank you for the use of only 2 lemons, also for above reason. And, one last thank you for using graham crackers. I have to be gluten free, regrettably, and I have gluten free graham crackers in my pantry. So many wins in one recipe! You’re the best!

  12. Oanh

    Dumb equipment question but have been hunting obsessively for your 8×8 pan – love that it is a light color and perfectly square with sharp corners. I haven’t been able to find it – what pan is it, and any chance you would be able to provide a link for purchase? Thank you!

      1. Oanh

        Thank you!! The pan looks a little lighter in your photos than on the WS site so I wasn’t sure – will order with confidence!

  13. JP

    The problem with Meyer lemons is that they are not tart enough for a dessert like this. After all, they are a cross between the Eureka lemon and the mandarin orange. I have made lemon desserts with them and been disappointed. Add on a very sweet meringue and, at least in my opinion, there is not enough contrast. Meyer lemons are really popular right now, and here in CA they are very easy to find, but if you really want to taste lemon, stick with Eureka, that plain old grocery store lemon and go with Deb’s instructions about the rind, which can be much thicker than a Meyer.

    1. deb

      I agree — I’m not as into them as most cooking people. However, here, adding the extra lemon juice can go far to making up for the missing tartness.

    2. Mary

      Yes ! Eureka lemons are the way to go and what I also would use for this recipe. They have that great tartness that is so good in a lemon dessert. I used Meyer lemons once in some lemon bars and they just did not have much of a tart lemony taste.

  14. Mado

    Hi Deb, I’m confused by the step where you pull out the parchment paper and then transfer to a baking sheet. So to be clear, the last step when we add the meringue is done once the base it out of the baking pan and now on a sheet?Maybe it’s exactly as stated — but I have a hard time imagining that the base+filling can be removed en bloc from the high-sided pan and keep its shape…! Thanks for clarifying, I CANNOT wait to try this as I love whole-lemon tarts!

  15. Kate

    These look delicious! I have a largish lemon whose zest I already took off sitting in the fridge. Do you think that would work, or be too quiet in flavor?

    1. deb

      Lol, we all have a collection of naked lemons in our fridge, huh? I do think the zest is pretty key here, though, but you could take it off the next lemon, the one you’ll use for juice, and pay it forward. ;)

      1. Lauren

        For those of us who don’t have many people to share this with at the quarantine moment (but could probably eat a 1/4 of a tray in one sitting :-) ). How long would you say this could last for in the fridge? I know meringue is best day of. If we don’t mind it a little soggy do you think it would last for a couple of days?


  16. Joanne Vansickle

    Our favorite Italian restaurant sometimes serves this, has to be in the best dessert ever. Can’t wait to try it out.

  17. narya

    This may be the first thing I make when I have an oven again (oven died in January, kitchen reno happening as I type . . .). I often use italian meringue for anything that won’t be completely consumed in a day–another alternative, if you need to make it ahead of time, is to make italian meringue “drops” and bake them for awhile in a very very low oven, then place on top when you want to serve and torch them then.

  18. CT

    I made these for a picnic and they were delicious and quite easy! I used a whole Meyer lemon and the juice of half a regular lemon. Next time I’d reduce the sugar in the lemon curd a bit.

  19. Beth S

    I want to love this recipe for sooo many reasons, but the bottom crust and filling was cloying and gooey in a greasy way. Maybe I did something wrong?? If not, next time less butter in the crust, less butter in the filling unless I add more ingredients. In comparing this to your whole lemon bars (which are my favorites), I want to try whole eggs and maybe the cornstarch. What I loved about this recipe: the meringue was sensational and any chance to use my blowtorch is a win! The bars were beautiful & the taste was super lemony.

  20. Elisa

    Hi Deb! I can’t shake the idea of a honest to goodness shortbread crust for these bars, and heaven knows you have plenty of amazing recipes to choose from! Would I bake the shortbread completely and then add the filling or would I need to do something different? Or should I just trust the grahm crackers?

    Either way, these will be made this weekend. Thank you for all you do!

  21. Ree

    Oh man! Seeing this recipe on here this morning was a dream come true of mine. Also the first time I’ve made this kind of meringue myself before! (Is it Swiss? Italian? I can never tell the difference).

    Anyway, a few notes: This was WAY sweeter than I expected, mostly because I expect recipes coming from Smitten to be dialed back on the sweetness, for the most part! I had an instinct to reduce the sugar in the crust or the filling but went against it, which I feel was a mistake. The final result is of course delicious, but tooth-achingly sweet with not as much contrast between the literal heaps of meringue and the much thinner lemon filling. This also may have been because I made the recipe as written, with graham crackers and with the vanilla, as opposed to how Deb made them.

    Second, I also found the instructions on making the meringue a little confusing at first. I basically put my stand mixer bowl on top of a pot filled almost halfway with water, and vigorously whisked with a long balloon whisk. A hand mixer would be great, but I don’t have one! I then moved to my stand mixer, as stated. Ended up working great!

    Thanks for the recipe, and can’t wait to make again when I can pawn some of the sweetness off on friends :)

    1. Gina Lowry

      I ended up skipping the sugar in the crust (happy accident), and it was plenty sweet with just the sweetness in the graham crackers.

  22. Sydni Rubinstein

    As someone who usually messes up multi-step baking projects, I was definitely not expecting this to be the BEST THING EVER. Even before it was halfway done, I knew that this was worth it just for the heavenly lemon filling I got to lick off of the bowl and spoon halfway through.

    I’m sad my husband is neither a lemon nor meringue person, but I am both and will be finding others who are so that I can make this again in the future!!

    Extra note: Made this with Earth Balance (non-dairy butter substitute).

  23. emily

    I made these yesterday with no modifications to the recipe. However, I only have a ceramic baking pan, and it is thicker than a regular metal baking pan.

    Like other commenters, I was surprised by how sweet these bars are. If I were to make them again I think I’d take the sugar out of the crust and try to halve the sugar in the filling. My crust also became gloopy and gummy – you can scoop it out of the dish with a spoon but definitely no hope of cutting it into bars. I think my thicker pan may have contributed to the lack of “crustiness” in the crust. My meringue also never got stiff even after nearly ten minutes of beating, but it was getting thicker so I just spread it once it was thick enough to hold a texture. I made a linear pattern with a fork that came out quite pretty after a quick broil!

    I will say that I’m operating in a rental kitchen, so not the best equipment, and it was pretty warm in here without AC so perhaps that’s why my meringue had issues. I love the “whole lemon” idea, as the flavor was more complex with that element of bitterness. I also appreciated how efficient the recipe is – no wasted egg yolks or whites! I think I may try making this filling and swirling it into a cheesecake.

    Overall the result wasn’t 100% what I’d hoped but certainly has elements I would use again. Interesting recipe, thanks Deb!

  24. uh, ah, oh, well – wow, it does looks fantastic but I am getting a little bit squirmish about a pound of sugar these days. Lockdown and being shackeled 24/7 (I did not say this out loud, did I?) to two four-year-olds has not done wonders to the figure. How are you handeling this?

  25. Jean

    I’ve made an Arizona Sunshine Lemon Pie (I live in the Phoenix area). It uses a lwhole, seeded lemon, is made in the blender, poured into a pie crust and baked. Very easy and really delicious. We prefer it to any lemon meringue pie we’ve ever tried. It just uses a large lemon, 4 eggs, 1/2 cup melted butter, 1 tsp vanilla and 1 1/2 cups of sugar (and, of course, a pie crust!).

  26. DV

    I’m in the middle (I guess) of making these. Crust and filling are done and chilling in the fridge. Since so many hours elapse between separating the eggs (you use the yolks right away but not the whites), I assumed I should put the whites in the fridge until it’s time to make the merengue??? [There’s this vague ‘when you’re ready to make the merengue’ in the instructions which doesn’t give me any kind of time frame in terms of using or storing the whites.] Anyway, do I need to let the whites come to room temp before making the merengue? And can the pan stay in the fridge for hours before the merengue is added?
    Thanks for anyone’s help!

  27. Rebecca

    Hi – I’m uncertain as to why the meringue gets made an hour before serving but broiled when you are ready to finish. 1) Does it need to go back in the fridge after the meringue goes on it, before it’s broiled? 2) Sorry if this is dumb – does “ready to finish” = “ready to serve”?

    I guess what I am really asking is whether I can make the meringue and then immediately broil, and whether it needs an hour in the fridge after meringue is made. Thanks so much!

    1. DV

      Yes, that’s not clear! I’m getting ready to make the merengue and was planning to toast it right away then store in the fridge until dinner (2 hours). But maybe I should make and spread on the merengue, and store in the fridge until after dinner and then toast the top just before serving… maybe the texture is best when first toasted? Hope that’s correct!

  28. DV

    Must be me but the directions are so confusing! Broiled the meringue… do I serve them now or chill them? It says ‘refrigerate until ready to serve’… until they’re chillled or???!!!

  29. Jennifer Plank

    these were really lovely – the bittersweet of using the whole lemon made all the difference – i had to switch crust recipes (for a conventional flour, sugar butter base) but i will make that filling over and over again, very reminiscent of lemon curd with a twist

  30. Terrible Baker

    I’m going to be honest I stan 99% of SK recipes but this one did not work for me at all. My crust got burned, the filling was inedibly bitter, and the meringue wound up salty (this one is my fault, because I should have known better than to use a full pinch of Morton). I wound up feeling like I should have not bothered parbaking the crust and should have just used a combination of zest and juice rather than trying to put the whole lemon in there. It’s weird because each element was very tasty before getting baked. But despite 2 1/4 cups of sugar the whole thing was so bitter sour and salty that I had to throw it away. Clearly I missed something here because I see a lot of comments saying it was very sweet. Pretty disappointed so many ingredients went to waste

  31. Rebecca

    I made this and the whole family agreed it was delicious. Worth the steps. Some of us have celiac disease so I used Pamela’s honey graham GF crackers and the crust was delicious. I was short on time so I had to put the bars in the freezer (pre-meringue) before they were fully cooled, and it seemed to be okay. No parchment paper so I did the meringue in the original 8 by 8 dish (which I had greased really well with butter before baking the crust) and that worked fine. I had been confused about whether there needed to be a lapse in time between making the meringue and broiling the top — I did not wait, and that was also fine. Definitely watch it closely — I should have pulled it out from under the broiler about 45 seconds earlier. Thank you! The whole lemon trick is very cool.

  32. Karoline Hurd

    Thanks Deb! Delicious, good lemon flavor and easy! Made for a small dinner party last night. I’m a big fan now of the 8 x 8 for smaller groups (made your dulce de leche cheesecake squares recently). One minor change—I melted the butter for the crust and used boxed graham crumbs—so quick. Meringue turned out with a perfect texture also.

  33. Rebekah

    I made these with the following substitutions: Crust made of ritz crackers, 2 Tbsp butter and 3 Tbsp coconut oil; curd blended in the food processor with 4 Tbsp butter and 4 Tbsp olive oil; Cut 20 g of sugar from the curd.

    Overall a fun dessert, but I’ll stick with the whole lemon bars instead. I had an easy time making the Italian meringue, which was my first time, but the bars are a tad messy. Delicious, but messy.

  34. Caroline Taylor

    I made these tonight and they were delightful- I was so pleasantly surprised at how easily and quickly they come together (and the lack of dishes was impressive). Reminded me of the much loved, much missed lemon meringue pie from Chick-Fil-A.

    I go gah-gah for anything with meringue, but found mine to be too sweet/too much, which was surprising. On my 9×9 square lemon bars, the final layer was nearly two inches thick (!!!). Next time I’d like to decrease the amount, but not sure how… do you think it was over-whipped? I used the whisk on a hand-held mixer while it was heating and turned it on low for most of the heating process. Or I can just decrease the egg whites and sugar by half next time?

    Fabulous recipe- thank you!

    1. Kathleen

      That would work. Another idea would be to dollop the extra meringue onto a parchment-lined tray and bake in a really low oven for a long time (essentially dehydrating the egg white mixture) for crunchy meringue goodness…

  35. monica

    Yum! I made these with a few tweaks and loved them! First, I used Goya brand Maria’s cookies for the crust, with half the sugar called for in the recipe. I increased all the ingredients in the lemon layer by one half, except kept the sugar at 200g. Took about 35 minutes to bake with the increased volume. The meringue is perfect. I preferred the increased lemon layer as that was a better tangy-to-sweet ratio for me. I made these yesterday and this morning they’re still perfect- no signs of meringue weeping in the fridge.

  36. Ani

    I was very excited to make this but didn’t turn out great. Not sure what I did wrong as reading the other comments seems like this isn’t a problem. The crackers base and the lemon custard mixed for some reason. As a result I couldn’t cut the bars as pieces were sticky and crumbling. The meringue turned out absolutely ok. Way too sweet overall. I cam understand that meringue would need the suggar but lemon custard was way too sweet.

  37. DV

    These bars were delicious, just a bit confusing to make for me. I used Annie’s bunny honey graham’s for the crust; they are very sweet so I didn’t add sugar – worked fine. The lemon layer was delicious; I mixed everything in a food processor (took a while for the filling to get creamy, but it did). I used an average sized lemon with 3/4 cup sugar (instead of 1 cup); it was the perfect balance between sweet/tart. The meringue was simple to make; took a bit longer for mine to form stiff peaks but otherwise was an easier task than I feared. It makes a lot but it was fun to pile it all on top of the lemon filling and is so marshmallow-y delicious. I liked the ratios of the layers. I don’t have a torch so I browned the meringue for about 1 minute under the broiler; worked fine, just not quite as pretty as a torch.
    So for those who thought the recipe was too sweet:
    Taste the graham crackers or cookies you’re using for the crust; if they’re super sweet (which most of them are), adjust or eliminate the sugar.
    The lemon layer worked fine with 3/4 cup of sugar instead of 1 full cup (but that will depend on the size/bitterness of your lemon).
    I used all the sugar called for in the meringue; we thought it was just right.
    The bars have kept very well in the fridge for 3 days.

    This is perfect timing as i’ve been requested by my husband for a lemon meringue pie for his birthday dinner this weekend!
    I love the streamlined nature of the recipe, but am interested in the texture of the meringue? Is it crispy on top (once browned) and firm underneath, or more soft and chewy, like marshmallow?


    This was yummy, but I would have liked more of the lemon layer. Wondering big a mash up of this and your awesome lemon bar recipe would work. The meringue was fantastic but very sweet. It looks amazing, a real wow of a dessert. Feeds 8-10 easily.


      Meant to say “if a mash up” not big mash up! 😆 Like, could you combine the two lemon bar recipes to have more lemon in this one.

    I made these on Saturday and I’m not sure they’re worth the work. Despite using a thin skinned lemon and a high speed blender, I had to strain bits of rind out of the filling to get it smooth. Some of the crust ended up in the filling, which I think may have been because it was too warm when I filled it. Filling ran under the parchment and the bars were hard to separate form the paper.
    When I finally finished, they were ok enough for me to try again at some point (with less sugar) but overall I was disappointed with the outcome vs the work (and surprised because I’ve never had a less than fabulous outcome from this site!)

      Theoretically, but with a couple caveats. One, I don’t find whole-lime desserts as enjoyable as whole-lemon, but that just might be my personal tastes. Two, the taste of key lime is from the combination of lime juice + sweetened condensed milk, see this Key Lime Pie and/or Key Lime Cheesecake. Three, you might instead use this lime curd for the lemon part, which is a little closer to the lemon here but without the whole rind.

    I made these this weekend, and followed the recipe to the letter…I used my food processor for everything (except the meringue), because I don’t have a blender, these were amazing (and pretty). Being a citrus aficionado I will make these again and again and I love the marshmallow meringue. I have made the smores cake in the past so I would imagine these probably need consumed within two days, or less, before the meringue begins to get soupy….no problem!

    I love this site in general but agree with the comments that this recipe was a disappointment… the filling was more bitter than sour (despite using a very thin-pithed, small lemon) and completely overwhelmed by the quantity and sweetness of the meringue. Don’t know that I’d make it again, but if I did I’d further reduce the sugar in the filling (I already reduced by a third), add more juice, and halve the meringue.

    I made these a few nights ago for a summer dessert, and they were delicious! My family loved them, and they were the perfect complement to a hot day. I cut back on the sugar a bit in the meringue and filling, which really helped balance out the different components of the recipe. This is a must make!!

  44. David

    LOVED these. And I also learned what “pith” is!

    I did cut back the sugar on the crust by half and saw no problem, cut the filling sugar back a little bit as well. I agree this is pretty sweet even with this, but meringue you can’t mess with. Will be trying a chocolate version to make this a full on smore experiment.

    One thing I didn’t get is the parchment removal, or the need for it in the first place (is this Deb’s OCD on clean up haha). Why not just grease the pan? You eliminate the dangerous possibility of destroying the entire thing by taking it out and putting it back in. What I ended up doing by accident was cutting around the edge which cut thru the parchment on the side and I just pulled the sides out. But it did mess up the edges, so next time I’m going with buttering the pan and simplifying it altogether.

    1. deb

      For two reasons, you want to remove the parchment. One, it really, really sticks to the meringue as it sets so it’s best to separate it sooner. And two, it will burn (like, with tiny flames) when you torch or broil the top. Glad you enjoyed the bars!

  45. Elizabeth Richards

    ooohhh, what a lovely idea. My husband loves tart key lime pie which usually has me juicing 3-4 limes and zesting 10-12. I’ve been looking for an alternative dessert that doesn’t leave me with bloody knuckles or 8 naked limes. When I say tart, I mean tart!

    Do you think I could substitute limes for the lemons in this recipe? Would the amount of sugar stay the same or do you think I would need more?

    I am a big fan. Deb, and was excited to make this recipe. But somehow the filling and crust meshed together, and it was impossible to remove the parchment from the sticky bittom without destroying the crust/filling, which seem like they are one layer. In the end I flipped the whole thing upside down and put it under the broiler, crust side up. I’ve checked the ingredients several times, and baked both the crust and filling longer than suggested as the crust was not browning and the filling never did bubble. Any idea of where I went wrong?
    PS I checked the oven temp with a thermometer and oven is accurate.

    1. deb

      I wonder if the filling just spilled out and under the crust? But still, the parchment paper should separate. May I ask what brand you use? (I keep a mental checklist of the ones that work well and the ones that have failed us.)

    These lemon meringue pie bars are delicious! Based on comments about them being overly sweet, I halved the sugar in the crust and used 3/4 c. sugar in the filling. It was great, but next time I will probably leave out the sugar in the crust, and reduce the sugar in the filling to 2/3 c.
    I don’t have a food processor, but do have a Vitamix blender, so I made the crust using the dry container, and made the filling using the regular Vitamix container. Worked perfectly!

    The key lime pie being one of my favourites on the site, I had to try this recipe. I halved it and had to substitute the graham crackers for digestive biscuits, since we don’t have graham crackers here. Reading the comments, I reduced the sugar in the lemon filling by an extra 50%, used a whole small organic lemon plus juice of half a lime (what I had lying around), and this worked out perfectly. Making the Swiss meringue was my first time but was easy, and it appears to keeping well in the fridge (day three now). My base was the right texture and did not mix with the lemon layer, as some others experienced.

    All in all, relatively easy, good-looking and very tasty recipe, but the sugar in the lemon filling should be reduced by half (and maybe leave it out of the base).

    A word of advice – allow yourself plenty of time for these to chill before removing parchment! Mine seemed reasonably set when I took them out of the oven – a little loose in the middle but per the recipe sounded like they would set up. I rushed the cooling process in the freezer but definitely not for long enough – when I attempted to remove the parchment, it was partly stuck to the crust due to some of the filling running under the crust. Disaster – the filling was almost liquid in the middle and it went everywhere! I patched it together, added the meringue, toasted it under the broiler, and it pretty much had to be eaten with a spoon. The crust and meringue were delicious, but the filling was waaaayyyy too bitter for my lemon-loving family. I used an average grocery store lemon with pretty thin rind, but I guess next time I’ll find a Eureka if possible.

    I made these with Anna’s ginger cookies as the crust (store was out of graham crackers)—delicious, though it may not have needed the extra sugar or as much butter. Excellent recipe, will definitely be making these again!

    I made this with mixed results. Didn’t feel like washing my food processor so bashed the graham crackers in a baggie, added sugar, salt, and cubes of butter and bashed it some more until it was the right texture. Lemons were small so used 1-1/2 and I whirled the lemon mixture on high in my blender, very satisfying. Didn’t want to wash my stand mixer either so used a hand mixer on high for the meringue and it worked fine.

    I had issues with my overhanging parchment flopping down onto the lemon layer in the oven–super annoying, would use foil next time.

    Graham cracker a little too cooked after 10 minutes alone and then 30 with filling, so next time would cook it a little less in both steps.

    Thought making the meringue was fun but taste-wise it was too much and too sweet–just my personal preference, so I would half the topping recipe. Which would ruin the symmetry of 4 yolks and 4 whites :-)

    Overall, it is tasty but the whole not quite as good as its parts.

    Made these for family of pie lovers and they were a fantastic hit. Based on others’ comments I didn’t add any sugar to the Graham cracker mix in crust, and cut back to 1/2 cup in the filling, and it was just perfect. Still plenty sweet. Used regular eureka lemons. Also baked on regular aluminum foil (not non-stick) and just trimmed off the excess on the sides (we didn’t need a fancy presentation). 10/10 would make again, the lemon flavor really is deeper and more complex than any other I’ve tried. Perfect proportions in an 8×8.
