Ingredients
To create the perfect Lemon Meringue Pie, you need to gather high-quality ingredients. Each component plays a crucial role in the final taste and texture of this classic dessert. Let’s break down the ingredients for each layer: the crust, the luscious lemon filling, and the cloud-like meringue topping.
For the Pie Crust
A flaky, buttery pie crust is the foundation of any great pie. This recipe utilizes a classic pastry crust, but you can also adapt it to your preferred method. Using cold ingredients is key to achieving a tender and flaky crust.
- 1 ½ cups (190g) All-Purpose Flour: All-purpose flour provides the structure for the crust. Make sure to measure it correctly, using the spoon and level method to avoid using too much flour, which can result in a tough crust. For a slightly more tender crust, you can substitute a couple of tablespoons of all-purpose flour with pastry flour.
- ½ teaspoon Salt: Salt enhances the flavor of the crust and balances the sweetness of the filling and meringue. Don’t skip it!
- ½ cup (1 stick or 113g) Unsalted Butter, very cold and cut into small cubes: Cold butter is essential for creating flaky layers in the crust. When the butter melts in the oven, it creates steam, which separates the layers of dough, resulting in a flaky texture. Use unsalted butter so you can control the saltiness of the crust.
- ¼ cup (60ml) Ice Water: Ice water keeps the dough cold and helps to bind the dry ingredients together. Add it gradually, just until the dough comes together. Too much water will make the dough tough.
For the Lemon Filling
The lemon filling is the heart of the pie, providing that signature tart and tangy flavor. Freshly squeezed lemon juice and zest are non-negotiable for the best flavor.
- 1 ½ cups (300g) Granulated Sugar: Sugar not only sweetens the filling but also helps to thicken it. Granulated sugar works best for this recipe.
- ⅓ cup (30g) Cornstarch: Cornstarch is the thickening agent for the lemon filling. It creates a smooth, glossy texture when cooked. Make sure to whisk it thoroughly with the sugar before adding liquids to prevent lumps.
- ¼ teaspoon Salt: A pinch of salt enhances the lemon flavor and balances the sweetness.
- 1 ½ cups (360ml) Water: Water is the liquid base for the filling.
- 6 Large Egg Yolks: Egg yolks add richness, color, and further thickening to the lemon filling. Use large eggs for consistent results. Separate the eggs carefully, ensuring no yolk gets into the egg whites, as even a trace of fat can prevent the meringue from whipping properly.
- ½ cup (120ml) Freshly Squeezed Lemon Juice: Freshly squeezed lemon juice is crucial for the bright, vibrant lemon flavor. Bottled lemon juice often lacks the same freshness and tang. You’ll need about 4-5 lemons to get ½ cup of juice.
- 2 tablespoons Lemon Zest (from about 2 lemons): Lemon zest adds intense lemon flavor from the oils in the lemon peel. Use a microplane or fine grater to zest the lemons, being careful to only zest the yellow part and avoid the bitter white pith underneath.
- 2 tablespoons Unsalted Butter, cut into small pieces: Adding butter at the end of cooking the filling adds richness, shine, and a smoother texture.
For the Meringue Topping
The meringue is the crowning glory of the Lemon Meringue Pie. It should be light, airy, sweet, and perfectly toasted. This recipe uses a classic meringue made with granulated sugar.
- 6 Large Egg Whites: Use the egg whites leftover from the filling. Make sure they are at room temperature, as room temperature egg whites whip to a greater volume. Ensure your bowl and whisk are scrupulously clean and free of any grease, as this will hinder the egg whites from whipping properly.
- ¼ teaspoon Cream of Tartar: Cream of tartar is an acid that stabilizes the egg whites, helping them whip to stiff peaks and preventing the meringue from collapsing or weeping. If you don’t have cream of tartar, you can substitute a teaspoon of lemon juice or white vinegar.
- ½ cup (100g) Granulated Sugar: Sugar sweetens the meringue and further stabilizes it. Add it gradually after the egg whites have started to whip to soft peaks.
Instructions
Making Lemon Meringue Pie is a multi-step process, but each step is manageable if you follow the instructions carefully. We’ll break it down into three main parts: making the pie crust, preparing the lemon filling, and creating the meringue topping and assembling the pie.
Making the Pie Crust
- Prepare the Dry Ingredients: In a large bowl, whisk together the flour and salt. This ensures the salt is evenly distributed throughout the flour.
- Cut in the Cold Butter: Add the cold, cubed butter to the flour mixture. Using a pastry blender or your fingertips, cut the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces of butter remaining. The goal is to keep the butter cold and in small pieces, which will create flaky layers. If using your fingertips, work quickly to prevent the butter from warming up too much.
- Add Ice Water: Gradually add ice water, one tablespoon at a time, mixing gently with a fork after each addition. Mix until the dough just comes together and is no longer crumbly. Be careful not to overmix, as this will develop the gluten in the flour and result in a tough crust. You may not need to use all the ice water.
- Form a Disc and Chill: Turn the dough out onto a lightly floured surface. Gently gather it into a disc, about 1 inch thick. Wrap the disc tightly in plastic wrap and refrigerate for at least 1 hour, or preferably 2 hours. Chilling allows the gluten to relax, making the dough easier to roll out and preventing it from shrinking during baking.
- Roll Out the Crust: On a lightly floured surface, roll out the chilled dough into a 12-inch circle, about ⅛ inch thick. Roll from the center outwards, rotating the dough as you roll to ensure an even circle. If the dough starts to stick, lightly dust the surface and rolling pin with flour.
- Transfer to Pie Plate: Gently fold the dough in half, then in quarters, and transfer it to a 9-inch pie plate. Unfold the dough and gently press it into the bottom and sides of the pie plate, being careful not to stretch it. Trim any excess dough hanging over the edge, leaving about a ½-inch overhang.
- Crimp the Edges: Crimp the edges of the crust decoratively using your fingers or a fork. This not only looks nice but also helps to seal the edges and prevent the filling from leaking.
- Pre-bake the Crust (Blind Bake): Prick the bottom of the crust all over with a fork. This prevents the crust from puffing up during baking. Line the crust with parchment paper or foil and fill it with pie weights or dried beans. Blind baking is essential for Lemon Meringue Pie to ensure the crust is fully cooked and crisp before adding the wet filling.
- Bake: Bake in a preheated oven at 375°F (190°C) for 20 minutes. Remove the parchment paper and pie weights and bake for another 10-15 minutes, or until the crust is lightly golden brown. Let the crust cool completely before filling.
Making the Lemon Filling
- Combine Sugar, Cornstarch, and Salt: In a medium saucepan, whisk together the granulated sugar, cornstarch, and salt until well combined. This ensures the cornstarch is evenly distributed and prevents lumps in the filling.
- Whisk in Water: Gradually whisk in the water until the mixture is smooth and there are no lumps of cornstarch remaining.
- Cook over Medium Heat: Place the saucepan over medium heat and cook, stirring constantly with a whisk, until the mixture comes to a simmer and thickens significantly. This usually takes about 5-7 minutes. The filling should be thick enough to coat the back of a spoon.
- Temper the Egg Yolks: In a separate small bowl, whisk the egg yolks lightly. Tempering the egg yolks prevents them from scrambling when added to the hot filling. Gradually whisk a few tablespoons of the hot filling into the egg yolks to warm them up. Continue adding hot filling, a little at a time, whisking constantly, until the egg yolks are warmed.
- Add Tempered Egg Yolks to Filling: Pour the tempered egg yolk mixture into the saucepan with the remaining hot filling. Whisk constantly and cook for 1 minute more, or until the filling is very thick and glossy. Be careful not to boil the filling rapidly at this stage, as it can cause the eggs to curdle.
- Remove from Heat and Stir in Lemon Juice and Zest: Remove the saucepan from the heat. Stir in the freshly squeezed lemon juice and lemon zest. The lemon juice will brighten the flavor and thin the filling slightly, but it should still be quite thick.
- Stir in Butter: Stir in the butter until it is melted and fully incorporated into the filling. The butter adds richness and shine to the filling.
- Pour into Crust: Pour the hot lemon filling into the pre-baked and cooled pie crust. Spread it evenly with a spatula.
Making the Meringue Topping
- Prepare Egg Whites: Ensure your mixing bowl and whisk are clean and grease-free. Place the room temperature egg whites and cream of tartar in the bowl of a stand mixer fitted with the whisk attachment, or use a hand mixer.
- Whip Egg Whites to Soft Peaks: Beat the egg whites on medium speed until soft peaks form. Soft peaks are when the meringue forms peaks that gently fold over at the tips when the whisk is lifted.
- Gradually Add Sugar: Gradually add the granulated sugar, one tablespoon at a time, while continuing to beat on medium-high speed. Beat until all the sugar is incorporated and the meringue is glossy and stiff peaks form. Stiff peaks are when the meringue forms firm, upright peaks that hold their shape when the whisk is lifted. The meringue should be smooth, glossy, and hold its shape well.
- Spread Meringue on Pie: Immediately spread the meringue over the hot lemon filling, making sure to seal it to the edges of the crust to prevent weeping. Create decorative swirls and peaks with a spatula or the back of a spoon.
- Bake or Broil Meringue:
- Oven Baking: Bake in the preheated oven at 375°F (190°C) for 10-15 minutes, or until the meringue is lightly golden brown on the tips. Watch carefully, as meringue can burn quickly.
- Broiling: For a quicker method, you can broil the meringue. Preheat your broiler to low. Place the pie under the broiler for 1-2 minutes, watching very closely, until the meringue is lightly golden brown on the tips. Broiling requires careful attention to prevent burning.
- Cool Completely: Remove the pie from the oven or broiler and let it cool completely at room temperature for at least 2-3 hours before slicing and serving. This allows the filling to set and the meringue to stabilize. Do not refrigerate the pie while it is still warm, as this can cause condensation and make the meringue weep.

Additional Tips for Perfect Lemon Meringue Pie
Creating a truly exceptional Lemon Meringue Pie involves attention to detail and understanding key techniques. Here are 5 essential tips to help you achieve pie perfection:
- Keep Ingredients Cold for a Flaky Crust: The secret to a flaky pie crust is cold ingredients. Use very cold butter, ice water, and even chill your flour and bowl if possible. Cold butter prevents gluten development and creates steam during baking, resulting in those desirable flaky layers. Work quickly when making the crust to keep the butter cold.
- Blind Bake the Crust Thoroughly: Blind baking (pre-baking) the crust is crucial for Lemon Meringue Pie. It ensures the bottom crust is fully cooked and crisp before you add the wet lemon filling. If you skip this step, you risk a soggy bottom crust, which is a common pitfall. Don’t skimp on the pie weights or beans to prevent the crust from puffing up unevenly.
- Temper Egg Yolks Carefully for a Smooth Filling: Tempering the egg yolks for the lemon filling is essential to prevent them from scrambling when added to the hot mixture. Gradually introduce the hot filling to the yolks, warming them slowly before adding the yolk mixture back to the saucepan. This ensures a smooth, creamy, and custard-like filling.
- Whip Meringue to Stiff, Glossy Peaks: Achieving the perfect meringue requires patience and proper technique. Ensure your egg whites are at room temperature and your bowl and whisk are grease-free. Whip the egg whites to stiff, glossy peaks, adding sugar gradually. A stable meringue is less likely to weep or deflate.
- Seal the Meringue to the Crust to Prevent Weeping: When spreading the meringue over the lemon filling, make sure to seal it completely to the edges of the crust. This creates a barrier and prevents moisture from seeping out from under the meringue, which is a common cause of weeping. Bring the meringue all the way to the crust edge, overlapping slightly.
Frequently Asked Questions (FAQ)
Here are some common questions bakers have when making Lemon Meringue Pie, along with helpful answers to ensure your baking success:
Q1: Why is my meringue weeping?
A: Weeping, or syneresis, occurs when liquid leaks out from under the meringue. Common causes include:
* Undercooked Meringue: If the meringue isn’t cooked long enough, the egg whites may not be fully coagulated and can release liquid.
* Overmixing Meringue: Overmixing can break down the protein structure in the egg whites, making them more prone to weeping.
* Sugar Ratio: Too much sugar can also contribute to weeping. Ensure you follow the recipe ratios.
* Humidity: High humidity can make meringue more prone to weeping.
* Cooling Too Slowly: Allowing the pie to cool too slowly can also cause weeping. Cool at room temperature, avoiding rapid temperature changes.
Q2: How do I prevent my pie crust from shrinking?
A: Pie crust shrinkage is a common issue. Here are tips to prevent it:
* Don’t Overwork the Dough: Overworking develops gluten, which can cause shrinkage. Mix just until combined.
* Chill the Dough: Chilling relaxes the gluten and makes the dough easier to handle and less likely to shrink.
* Don’t Stretch the Dough: When placing the dough in the pie plate, gently press it in without stretching it. Stretching causes it to snap back during baking.
* Blind Bake with Weights: Pie weights or beans help to keep the crust in place and prevent it from shrinking during blind baking.
Q3: Can I make Lemon Meringue Pie ahead of time?
A: Parts of the pie can be made ahead of time, but the assembled pie is best served within a few hours of making the meringue.
* Pie Crust: The pie crust dough can be made 1-2 days ahead and stored in the refrigerator. You can also blind bake the crust a day ahead and store it at room temperature in an airtight container.
* Lemon Filling: The lemon filling can be made a day ahead and stored in the refrigerator. Reheat it gently before pouring it into the baked crust if needed.
* Meringue: Meringue is best made just before assembling the pie. It’s not recommended to make meringue ahead of time as it can deflate and weep.
* Assembled Pie: The assembled pie with meringue is best served the same day it’s made. While it can be stored in the refrigerator for a day, the meringue may start to weep and lose its texture.
Q4: Can I use bottled lemon juice instead of fresh?
A: Freshly squeezed lemon juice is highly recommended for the best flavor in Lemon Meringue Pie. Bottled lemon juice often lacks the bright, vibrant flavor of fresh juice. If you must use bottled lemon juice, opt for a high-quality brand and taste test to adjust the sweetness if needed, as bottled juice can sometimes be more acidic. However, for optimal results, fresh is always best.
Q5: How do I store leftover Lemon Meringue Pie?
A: Store leftover Lemon Meringue Pie loosely covered at room temperature for up to 2 days. Refrigeration is not recommended as it can cause the meringue to weep and become soggy. If you must refrigerate, do so loosely covered and be aware that the meringue’s texture may change. It’s best to enjoy Lemon Meringue Pie as fresh as possible for the best meringue texture.
