Lemon Meringue Pie has a way of standing out on any table, whether it’s Easter or Mother's Day, a summer picnic, or part of a Thanksgiving dessert spread. With a crisp crust, bright lemon filling, and that perfectly toasted meringue, it looks impressive without feeling like a chore. I usually make it the night before so it’s chilled and ready when things get busy. It’s a reliable dessert favorite that feels just right for nearly any occasion.
In a bowl, rub the flour and butter together with your fingertips (or a fork) until the mixture looks like fine breadcrumbs. Stir in powdered sugar, beaten egg, and water. Mix until a dough forms. Wrap in plastic wrap and refrigerate for 30 minutes.
1 cup all-purpose flour, 6 ounces unsalted butter, ¼ cup powdered sugar, 1 large egg, 1 tablespoon cold water
On a lightly floured surface, roll dough to about ⅛-inch (3mm) thick. Line a 9-inch tart pan with the pastry, pressing gently into the edges. Trim excess.
Line with parchment paper, fill with baking beans, and bake for 15 minutes. Remove beans and bake for 5 more minutes, until lightly golden.
Reduce oven temperature to 340°F (170°C).
Make the Lemon Filling:
In a small bowl, mix lemon zest, juice, and cornstarch into a smooth paste. Bring the water to a boil in a saucepan. Whisk in the lemon-cornstarch mixture and stir until thickened. Remove from heat.
6 lemons Zest and juice, ¼ cup cornstarch, 1 ¾ cups water
In a separate bowl, whisk egg yolks and sugar until smooth.
1 cup sugar, 6 egg yolks
Gradually whisk the yolk mixture into the lemon base. Return to medium heat and cook, stirring constantly, until thick and glossy.
Let cool slightly, then pour into the baked pastry shell.
Make the Meringue:
With an electric mixer, beat egg whites until soft peaks form.
4 egg whites
Gradually add sugar, whisking until stiff, glossy peaks form. Add cornstarch and whisk briefly to combine.
1 cup powdered sugar, 2 teaspoons cornstarch
Spoon meringue over the lemon filling, spreading to the edges to seal. Create decorative swirls on top.
Use a kitchen torch to lightly toast the meringue (or bake at 400°F / 200°C for 8–10 minutes until golden).
Notes
Cold Butter Is Key: Keep your butter chilled when mixing the pastry to ensure a flaky crust that doesn’t shrink during baking.
Don’t Skip Chilling the Dough: Resting the dough in the fridge relaxes the gluten, preventing it from shrinking in the oven.
Use Room Temp Eggs: Egg whites whip up better and faster when they’re at room temperature.
Whip the Egg Whites Right: Start with a clean, dry bowl; any fat or moisture can stop them from whipping into stiff peaks.
Seal That Meringue: Spread the meringue to the edges of the pastry to prevent it from separating during baking.
Cornstarch Helps Stabilize: That little bit of cornstarch in the meringue makes it hold its shape and prevents weeping.
Cool the Filling Slightly: Pouring hot filling into the crust is fine, but give it a few minutes to cool so it doesn’t make the crust soggy.
Torch for Control: If you have a kitchen torch, it gives you more control over browning than the oven does.
