Why You’ll Love This Recipe
- Bright and balanced: a zingy lemon filling that’s creamy, not overly sweet.
- Dreamy contrast: crisp crust, silky curd, and a marshmallowy toasted meringue on top.
- Reliable meringue: Swiss-style meringue is stable, glossy, and less likely to weep.
- Showstopper finish: golden peaks look bakery-worthy but are totally doable at home.

Step-by-Step Instructions
Step 1: Make and chill the pie dough
In a large bowl, whisk together the flour, sugar, and salt. Add the cold butter cubes and cut them in using a pastry cutter or your fingertips until the mixture looks like coarse crumbs with some pea-size pieces of butter still visible.
Drizzle in 3 tablespoons (45 ml) ice water and stir with a fork. Add more water, 1 tablespoon at a time, just until the dough holds together when you squeeze a handful. (The dough should look a bit shaggy, not wet.)
Gather into a disk, wrap tightly, and refrigerate for 30 minutes.
Step 2: Roll out, shape, and blind-bake the crust
Preheat the oven to 425°F (220°C). On a lightly floured surface, roll the dough into a 12-inch circle. Transfer to a 9-inch pie dish, ease it into the corners without stretching, and trim to about a 1/2-inch overhang. Tuck the overhang under and crimp as you like.
Chill the shaped crust in the freezer for 10 minutes (this helps prevent shrinking). Line the crust with parchment paper and fill with pie weights or dried beans.
Bake at 425°F for 15 minutes. Carefully remove the parchment and weights, then reduce the oven to 375°F (190°C). Bake 12–15 minutes more, until the bottom looks dry and lightly golden.
Set aside on a rack. Keep the oven on (you’ll use it to toast the meringue).
Step 3: Prep your eggs and lemons
Separate 6 eggs, placing the yolks in a medium bowl and the whites in a clean, grease-free heatproof bowl (you’ll use the whites for Swiss meringue). Set aside the whites at room temperature while you make the filling.
Zest the lemons first, then juice them. Measure 3/4 cup (180 ml) juice and 1 tablespoon zest.
Step 4: Cook the lemon filling until thick and glossy
In a medium saucepan (2–3 quart), whisk together the sugar, cornstarch, and salt. Slowly whisk in the water until smooth, then whisk in the lemon juice.
Cook over medium heat, whisking constantly, especially as it begins to warm. After 6–10 minutes, it will turn from cloudy to translucent and begin to bubble. Once big bubbles break the surface, keep whisking and cook for 1 full minute to cook out the cornstarch taste.
Step 5: Temper the yolks, finish with butter and zest
Reduce the heat to low. While whisking the yolks constantly, ladle in about 1/2 cup of the hot lemon mixture in a slow stream (this gently warms the yolks so they don’t scramble).
Pour the warmed yolk mixture back into the saucepan, whisking continuously. Cook over medium-low heat until the filling is thick and reaches 170°F (77°C) on an instant-read thermometer, about 2–4 minutes (it should be steaming and glossy).
Remove from the heat. Whisk in the butter until fully melted and smooth, then whisk in the lemon zest.
Step 6: Fill the crust while everything is warm
Pour the hot lemon filling into the warm pre-baked crust and smooth the top. (Hot filling helps the meringue set and reduces the chance of weeping.)
Step 7: Make the Swiss meringue to stiff, glossy peaks
Set a saucepan with 1–2 inches of water over medium heat and bring to a gentle simmer. Place the bowl with the egg whites over the saucepan (the bottom of the bowl should not touch the water).
Add the sugar, cream of tartar, and salt to the whites. Whisk constantly until the mixture feels hot and the sugar dissolves, and the temperature reaches 160°F (71°C), about 4–6 minutes.
Transfer to a stand mixer fitted with the whisk attachment (or use a hand mixer). Whip on high until stiff, glossy peaks form and the bowl feels close to room temperature, about 4–7 minutes. Beat in vanilla, if using.
Step 8: Top, seal, toast, then cool and chill before slicing
Immediately spread the meringue over the hot lemon filling. Use a spoon or offset spatula to push the meringue all the way to the crust and slightly onto it to seal the edges (this helps prevent shrinking and weeping). Make swoops and peaks for plenty of toasty edges.
Bake at 350°F (175°C) for 12–15 minutes, until the peaks are golden brown. (Alternatively, keep the pie unbaked and use a kitchen torch to toast the meringue to your liking.)
Cool at room temperature for 1 hour, then refrigerate uncovered for at least 3 hours before slicing. For clean slices, wipe your knife between cuts.
Pro Tips
- Use hot filling under the meringue: Spreading meringue over hot lemon filling helps “cook” the underside and reduces weeping.
- Seal the meringue to the crust: Make sure the meringue touches the crust all the way around; gaps can cause shrinking.
- Keep everything grease-free for meringue: Even a bit of yolk or oil can prevent the whites from whipping properly. Clean bowl, clean whisk.
- Don’t undercook the cornstarch: Let the filling fully bubble and cook for 1 minute; undercooked starch can cause a runny filling.
- Chill for the right texture: The filling sets as it cools. If you slice too early, it may look looser than it should.
Variations
- Lime meringue pie: Swap the lemon juice and zest for lime (same amounts) for a sharper, tropical tartness.
- Ginger-cookie crust: Replace the pastry crust with a pressed crust made from 2 cups (240 g) crushed gingersnaps, 6 tablespoons (84 g) melted butter, and 2 tablespoons (25 g) sugar; bake at 350°F for 10 minutes.
- Extra-tangy filling: Reduce sugar to 1 1/8 cups (225 g) and add an extra 1 tablespoon lemon juice (15 ml) for more bite.
Storage & Make-Ahead
Best timing: Lemon meringue pie is at its best the day it’s made (crisp crust, stable meringue, fresh lemon flavor).
Refrigerate: Store leftovers in the refrigerator for up to 3 days. Loosely tent with foil (avoid plastic wrap pressed onto the meringue, which can stick). Expect the meringue to soften slightly over time.
Make-ahead options: You can blind-bake the crust 1 day ahead, cool completely, and store at room temperature wrapped well. You can also make the lemon filling up to 2 days ahead and refrigerate it with plastic wrap pressed directly on the surface; rewarm gently until steaming before filling the crust and topping with meringue.
Freezing: Not recommended; meringue texture deteriorates and may weep when thawed.
