Ingredients
For the Pie Crust
- 1 ¼ cups all-purpose flour
- ½ teaspoon salt
- 1 tablespoon granulated sugar
- ½ cup cold unsalted butter, cut into small cubes
- 3–4 tablespoons ice water
For the Lemon Filling
- 1 cup granulated sugar
- ¼ cup cornstarch
- ¼ teaspoon salt
- 1 ½ cups water
- 4 large egg yolks
- ½ cup fresh lemon juice
- 1 tablespoon finely grated lemon zest
- 2 tablespoons unsalted butter
- ½ teaspoon vanilla extract
For the Meringue
- 4 large egg whites, at room temperature
- ½ teaspoon cream of tartar
- ½ cup granulated sugar
- ½ teaspoon vanilla extract
Instructions
Step 1: Prepare the Pie Crust
In a large bowl, whisk together the flour, salt, and sugar.
Add the cold butter and use a pastry cutter or your fingertips to work it into the flour until the mixture resembles coarse crumbs with a few pea-sized pieces of butter remaining.
Gradually add the ice water, one tablespoon at a time, mixing just until the dough comes together.
Shape the dough into a disk, wrap it, and refrigerate for at least 30 minutes.
Step 2: Roll and Bake the Crust
Preheat the oven to 375°F (190°C).
Roll the chilled dough out on a lightly floured surface until it is slightly larger than your pie dish.
Transfer it carefully to a 9-inch pie dish. Press it gently into the bottom and sides, then trim and crimp the edges.
Prick the bottom several times with a fork.
Line the crust with parchment paper and fill it with pie weights or dried beans.
Bake for about 15 minutes. Remove the parchment and weights, then continue baking for another 8–12 minutes, or until the crust is lightly golden.
Set aside to cool.
Step 3: Make the Lemon Filling
In a medium saucepan, whisk together the sugar, cornstarch, and salt.
Gradually whisk in the water until smooth.
Cook over medium heat, stirring constantly, until the mixture thickens and begins to bubble.
In a separate bowl, whisk the egg yolks.
Slowly add about 1 cup of the hot sugar mixture to the egg yolks while whisking constantly. This gently warms the eggs and prevents them from scrambling.
Pour the egg mixture back into the saucepan.
Continue cooking for about 2–3 minutes, stirring constantly.
Remove from the heat and immediately whisk in the lemon juice, lemon zest, butter, and vanilla extract.
The filling should be smooth, thick, and glossy.
Pour the hot lemon filling into the baked pie crust.
Step 4: Make the Meringue
Place the egg whites and cream of tartar in a clean mixing bowl.
Beat on medium speed until soft peaks begin to form.
Gradually add the sugar while continuing to beat. Increase the speed and beat until the meringue forms stiff, glossy peaks.
Add the vanilla and beat briefly to combine.
Step 5: Top the Pie
Spoon the meringue over the hot lemon filling.
Spread it all the way to the edges of the crust, making sure the meringue touches the crust around the entire perimeter. This helps create a seal and can help prevent the meringue from shrinking away from the edges.
Use the back of a spoon to create decorative peaks across the surface.
Step 6: Bake the Meringue
Reduce the oven temperature to 350°F (175°C).
Bake the pie for approximately 12–15 minutes, or until the meringue is lightly golden brown.
Keep a close eye on it because the meringue can brown quickly.
Remove the pie from the oven and allow it to cool completely.
For the cleanest slices, refrigerate for several hours before serving.
Tips for Perfect Lemon Meringue Pie
Use Fresh Lemons
Freshly squeezed lemon juice gives the filling a much brighter flavor than bottled lemon juice. Finely grated lemon zest adds even more citrus flavor.
Don’t Skip Tempering the Eggs
Adding hot filling gradually to the egg yolks prevents them from cooking too quickly and becoming scrambled.
Put Meringue on Hot Filling
Spread the meringue over the filling while it is still hot. This helps the layers bond together and can reduce the chance of separation.
Seal the Edges
Make sure the meringue reaches the crust around the entire edge. This helps keep it from pulling away as the pie cools.
Don’t Underbeat the Meringue
The egg whites should form firm, glossy peaks. Underbeaten meringue can lose structure and become watery.
Avoid Humidity When Possible
Meringue can absorb moisture from humid air, which may make it softer or cause small droplets to appear on the surface.
How to Prevent a Watery Pie
A watery lemon meringue pie can happen when the filling isn’t cooked long enough, the meringue isn’t properly prepared, or the pie cools too quickly.
Make sure the lemon filling is properly thickened before pouring it into the crust. Also, spread the meringue over the filling while it is hot and allow the finished pie to cool gradually.
How to Store
Cover the pie loosely and refrigerate it.
For the best texture, enjoy it within 2–3 days. Avoid sealing a warm pie tightly because trapped condensation can make the meringue wet.
Frequently Asked Questions
Can I use a store-bought pie crust?
Absolutely. A refrigerated or frozen 9-inch pie crust can save time when you want the homemade lemon filling and meringue without making pastry from scratch.
Can I make the pie ahead of time?
Yes. The pie can be prepared several hours before serving and refrigerated. It is best served well chilled.
Why does my meringue shrink?
Meringue may shrink because it wasn’t properly sealed to the crust, the egg whites were under- or overbeaten, or the pie cooled unevenly. Spreading the meringue over hot filling and all the way to the crust edges helps.
Can I make the lemon filling less tart?
Yes. If you prefer a sweeter, milder lemon flavor, slightly reduce the lemon juice and add a little extra sugar. Keep in mind that changing the amount of lemon juice can affect the filling’s balance.
