Lemon Meringue Pie

This lemon meringue pie leans into that classic diner-style flavor that so many people love—bright lemon, a creamy filling, and a fluffy meringue piled high on top. I started making it during a stretch of testing heavier desserts, and I wanted something that felt lighter but still comforting and familiar. The graham cracker crust keeps it simple, the lemon stays smooth and tangy without being harsh, and the marshmallow-style meringue toasts beautifully whether I bake it as easy-to-slice bars or in a tart pan for a more traditional look.

Why I Love This Lemon Meringue Pie

Here’s what makes this version special and why it works so well at home:

• It keeps everything I love about lemon meringue pie: bright lemon flavor, a buttery crust, and a soft, pillowy meringue.
• The process is simplified without sacrificing texture or flavor, making it much more approachable to bake.
• Sweetened condensed milk creates a smooth, reliable lemon filling with fewer steps and consistent results.
• A marshmallow-style meringue adds height and balance without feeling fussy or overly technical.
• It works beautifully as either bars or a classic tart, depending on how you want to serve it.
• It’s the kind of dessert that instantly lifts the table the moment it’s set down.

Key Ingredients & Why I Use Them

Graham crackers – I use a graham cracker crust to keep the flavor classic and diner-style while balancing the tangy lemon filling.

Sweetened condensed milk – This gives the lemon layer a smooth, creamy texture and helps it set reliably without extra steps.

Eggs – The yolks enrich and set the lemon filling, while the whites whip into a soft, stable meringue that stays fluffy and glossy.

Fresh lemon juice (and zest) – Fresh juice gives the clean, bright citrus flavor this dessert depends on; zest is optional but adds depth.

How To Make This Pie

The full recipe and instructions can be found at the bottom of this post in the recipe card, but below I outline some step by step instructions to make sure you get everything right!

Step 1: Graham Cracker Pie Crust

I start by preheating the oven to 350°F and lining an 8×8 or 9×9-inch square pan with parchment, leaving a bit of overhang so the bars lift out easily. If I’m using a tart pan or pie plate, I skip the parchment. I pulse the graham cracker crumbs, sugar, and melted butter in a food processor until the mixture looks like wet sand, then press it firmly into the bottom of the pan or tart shell.

I bake the crust for about 10 minutes, just until it turns lightly golden, then set it aside to cool slightly while I make the filling. If I want to be extra sure it doesn’t puff up, I weigh it down with parchment and pie weights or dried beans. I keep the oven on for the next step.

Step 2: Lemon Filling

I whisk the sweetened condensed milk and egg yolks together in a large bowl until the mixture looks smooth and pale. Then I add the lemon juice and, if I’m using it, the zest, stirring until everything is fully combined—the filling will start to thicken slightly as it sits.

I pour the lemon filling over the warm crust and smooth the top. I bake it for 15–18 minutes, until the edges are set and the center still has a slight jiggle, then remove it from the oven and let it cool to room temperature before transferring it to the fridge to chill for at least 4 hours, or preferably overnight.

Once the filling is fully set, I use the parchment to lift the bars out of the pan and slice them with a sharp knife, wiping the blade between cuts for clean edges. If I’m using a tart pan, I simply unmold it before topping with the meringue.

Step 3: Marshmallow Meringue Topping

My favorite part! This is where the magic happens. To make the meringue, I start by bringing about 2 inches of water to a gentle simmer in a small pot. In a heat-safe glass bowl, I combine the egg whites, sugar, cream of tartar, and salt, then set the bowl over the pot like a double boiler. I whisk constantly until the mixture reaches 140ºF and the sugar is fully dissolved—this step helps the meringue whip up smooth, glossy, and stable. I look for gentle bubbling underneath, but I’m careful not to let it boil.

I remove the bowl from the heat and whip the mixture using a hand mixer or a stand mixer fitted with the whisk attachment. I beat it on medium-high speed for 10–15 minutes, until stiff, glossy peaks form and the meringue is thick, shiny, and able to hold its shape.

I add the vanilla extract and mix just until combined, then spread the meringue generously over the chilled lemon bars or tart. I use the back of a spoon to create peaks and swirls, then lightly toast the meringue with a kitchen torch for a golden finish, if I want a little extra contrast.

Tips & Tricks

This pie can be a little ticky to get right the first time, especially the meringue. Check out my tips!

• Fresh lemon juice makes a noticeable difference here; bottled just doesn’t have the same clean, bright flavor.
• Whipping the meringue to stiff peaks helps it hold its shape and toast evenly instead of slumping.
• Letting the lemon layer chill completely before slicing gives you clean cuts and a properly set filling.
• Parchment is worth using in a square pan—it makes lifting and slicing the bars much easier.

Variations on Lemon Meringue Pie

This pie is pretty much perfect on it’s own, but there are a few additions you can make to take it to the next level!

• Add a layer of raspberry jam or curd under the meringue for a delicious fruity twist (try my strawberry sauce).
• Swap graham crackers for gingersnaps or vanilla wafers for a different flavor base.
• Make it into mini tartlets for individual servings—perfect for parties.

Ingredients

 

Graham Cracker Crust

• 1½ cups graham cracker crumbs 150g
• 2 tbsp granulated sugar
• 1/4 tsp salt optional
• 6 tbsp unsalted butter melted 85g

Lemon Pie Filling

• 2, 14 oz cans of sweetened condensed milk
• 6 large egg yolks
• ¾ cup lemon juice
• 1 tbsp lemon zest optional, but recommended for flavor

Meringue Topping

• 2 large egg whites
• ½ cup granulated sugar 100g
• ¼ tsp cream of tartar
• ⅙ tsp salt
• 1 tsp vanilla extract

Instructions

 

• Preheat the oven to 350°F (175°C). Line an 8×8 or 9×9-inch square pan with parchment paper, leaving some overhang on the sides for easy removal if you want to make bars. Or if you want to make a pie, use a pie shell or tart shell.

Graham Cracker Crust

• In a food processor add graham cracker crumbs, sugar, salt, and melted butter. Pulse until the mixture resembles wet sand. Press firmly into the bottom of the prepared pan to form an even layer.
• Bake for 10 minutes. Let it cool while you prepare the filling.

Lemon Pie Filling

• In a large bowl, whisk together the sweetened condensed milk and egg yolks until smooth. Add the lemon juice and zest, and whisk again until fully combined. The mixture will thicken slightly on its own.
• Pour the filling over the warm crust and smooth the top. Bake for 15–18 minutes, or until the edges are set and the center looks just slightly jiggly.
• Let the bars cool, then refrigerate for at least 4 hours (preferably overnight) until fully set.
• Use the parchment overhang to lift the bars out of the pan. Slice into squares or rectangles. Wipe your knife clean between cuts for neat edges.

Meringue Topping

• Fill a small pot with 2 inches of water. Place it over medium heat. Bring to a gentle simmer.
• Add the egg whites, sugar, cream of tartar, and salt to a large glass bowl, and whisk to combine.
• Place the glass bowl on top of the pan to form a double boiler.
• Continue to whisk the mixture over the double boiler, until it reaches 140ºF, or until the mixture is just barely hot, and the sugar has entirely melted.
• Remove from the double boiler. Either whip the mixture in the bowl it already is using a hand mixer, or transfer the syrup to the bowl of a stand mixer, and whip using the whisk attachment.
• You should whip the syrup for about 10 to 15 minutes, or until stiff peaks form. The mixture should be thick, elastic, glossy, forming stiff peaks.
• Add the vanilla and mix to combine.
• Spread over the bars, toast with a torch if desired.

Notes

You can use one 12-inch tart pan to hold most of the filling, though it may be slightly shallower and you might have a thin layer. Or you can use two 9-inch tart pans, dividing the filling between them. You’ll get two tarts with slightly thinner layers.

Meringue: Make sure the whisk is reaching the bottom of the bowl when making the meringue. If the bowl is too large, the whisk won’t be able to fully work the meringue, since it’s not a huge amount. Other things to watch for that could derail the meringue: not beating at a fast enough speed, getting droplets of water in the syrup, or introducing any fat from egg yolks or utensils. Even a trace of oil or grease can prevent stiff peaks from forming.
