This lemon meringue pie is a classic American dessert featuring a buttery, flaky crust filled with a tangy, smooth lemon curd and topped with a cloud of fluffy, toasted meringue. It’s a showstopper for any occasion, and while it looks impressive, this recipe breaks down the process into manageable steps that any home baker can follow. The combination of sweet meringue and tart lemon filling is perfectly balanced, making it a refreshing end to any meal.
Ingredients
- 1 9-inch (23 cm) baked pie crust (store-bought or homemade, cooled)
- 1 cup (200 g) granulated sugar
- 1/4 cup (30 g) cornstarch
- 1/4 teaspoon salt
- 1 1/2 cups (355 ml) water
- 4 large egg yolks, lightly beaten
- 1/2 cup (120 ml) fresh lemon juice (about 2-3 lemons)
- 1 tablespoon (15 ml) lemon zest (from about 1-2 lemons)
- 2 tablespoons (28 g) unsalted butter, cut into small pieces
- 4 large egg whites, at room temperature
- 1/2 teaspoon cream of tartar
- 1/2 cup (100 g) granulated sugar (for meringue)
- 1/2 teaspoon vanilla extract
Instructions
- Prepare the crust: If using a homemade crust, bake and cool it completely before filling. If using a store-bought crust, follow package directions for a pre-baked crust. Set aside.
- Make the lemon filling: In a medium saucepan (off the heat), whisk together 1 cup (200 g) sugar, cornstarch, and salt. Gradually whisk in the water until smooth.
- Cook the filling: Place the saucepan over medium heat. Cook, stirring constantly with a whisk, until the mixture thickens and comes to a boil. This will take about 5-7 minutes. Boil for 1 minute, then remove from heat.
- Temper the egg yolks: Slowly whisk about 1 cup of the hot sugar mixture into the beaten egg yolks, a little at a time, to temper them. This prevents the eggs from scrambling.
- Finish the filling: Pour the egg yolk mixture back into the saucepan, whisking constantly. Return to medium heat and cook for 2-3 more minutes, until the mixture is thick and bubbly. Remove from heat.
- Add flavorings: Stir in the lemon juice, lemon zest, and butter until the butter is melted and the mixture is smooth. Pour the hot filling into the prepared pie crust. Set aside while you make the meringue.
- Preheat the oven to 350°F (175°C).
- Make the meringue: In a clean, dry bowl, beat the egg whites with an electric mixer on medium speed until foamy. Add the cream of tartar and continue beating until soft peaks form.
- Add sugar gradually: With the mixer running, add the 1/2 cup (100 g) sugar, 1 tablespoon at a time, beating well after each addition. Continue beating until stiff, glossy peaks form. Beat in the vanilla extract.
- Assemble the pie: Immediately spread the meringue over the hot lemon filling, making sure to seal the edges of the meringue to the crust to prevent shrinking. Use the back of a spoon to create decorative peaks.
- Bake: Bake for 10-12 minutes, or until the meringue is golden brown. Watch it closely to prevent over-browning.
- Cool completely: Place the pie on a wire rack and cool completely, away from drafts, for at least 2-3 hours before slicing. This allows the filling to set properly.
Tips
- Room temperature egg whites: For the fluffiest meringue, separate the eggs while cold, then let the whites sit at room temperature for 30 minutes before beating.
- Seal the meringue: Be sure to spread the meringue all the way to the edges of the crust. This “seals” the pie and prevents the meringue from shrinking during baking.
- Don’t overcook the filling: The filling will thicken more as it cools. If you cook it too long, it can become too stiff. Aim for a thick, pudding-like consistency.
- Fresh lemon juice is key: Bottled lemon juice can give a bitter or artificial flavor. Freshly squeezed lemon juice makes a significant difference in the brightness of the pie.
Serving Suggestions
Serve this pie chilled or at room temperature. It’s perfect on its own, but a dollop of whipped cream or a scoop of vanilla ice cream adds a nice touch. For a beautiful presentation, garnish with extra lemon zest or a few fresh berries. This pie is a wonderful dessert for spring and summer gatherings, Easter, or Mother’s Day.
Variations
- Lime Meringue Pie: Substitute the lemon juice and zest with lime juice and zest for a key lime-inspired twist.
- Orange Meringue Pie: Use orange juice and zest instead of lemon for a sweeter, less tart filling.
- Graham Cracker Crust: Swap the traditional pie crust for a graham cracker crust for a different texture and flavor.
- Add a layer of fruit: Spread a thin layer of raspberry jam or fresh berries on the bottom of the crust before adding the lemon filling for an extra fruity layer.
Storage and Reheating
Store leftover lemon meringue pie in the refrigerator, loosely covered, for up to 2 days. The meringue may weep or become soft after a day, which is normal. This pie is best served the day it is made. Do not freeze lemon meringue pie, as the meringue and filling will become watery and separate upon thawing. To serve leftovers, simply slice and enjoy cold or at room temperature. The meringue will not re-crisp well in the microwave, so it’s best not to reheat it.
Frequently Asked Questions
Why is my meringue weeping? Weeping (small beads of moisture on the meringue) is usually caused by undercooking the meringue or not sealing it to the crust. Make sure to spread the meringue to the edges and bake until the peaks are golden brown. Cooling the pie slowly away from drafts can also help.
Can I use a store-bought crust? Absolutely. A store-bought graham cracker or shortbread crust works well and saves time. Just make sure it’s fully baked and cooled before adding the filling.
Can I make this pie ahead of time? It’s best to make and serve this pie on the same day. The meringue will start to break down after 24 hours. If you must make it ahead, assemble it and refrigerate for up to 4 hours before serving.
Why did my filling turn out runny? The filling may not have been cooked long enough. It needs to come to a full boil and thicken before you add the egg yolks. Also, make sure you’re using the correct amount of cornstarch; too little will result in a runny pie.
Can I use a different sweetener? You can substitute the sugar with a sugar substitute designed for baking, but the texture and browning of the meringue may be slightly different. The filling will also set differently, so it’s best to stick with sugar for classic results.
How do I get clean slices? Use a sharp, thin-bladed knife dipped in hot water and wiped dry between cuts. This helps slice through the meringue and filling cleanly without dragging.
