In a medium saucepan, whisk together the granulated sugar, cornstarch, and salt.
Gradually pour in the water while whisking until the mixture is smooth and free of lumps.
Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens and begins to bubble.
Allow it to bubble gently for about one minute while continuing to stir.
In a separate bowl, whisk the egg yolks.
Slowly add a few spoonfuls of the hot mixture to the egg yolks, whisking constantly. This process gently warms the yolks and helps prevent them from scrambling.
Gradually whisk the warmed egg yolk mixture back into the saucepan.
Continue cooking over medium-low heat for another 1–2 minutes, stirring constantly, until the filling is thick and smooth.
Remove the saucepan from the heat.
Stir in the fresh lemon juice, lemon zest, and butter until the butter melts and everything is well combined.
The filling should be glossy, rich, and beautifully yellow, with a fresh citrus aroma.
Step 3: Pour the Filling Into the Crust
Pour the warm lemon filling into the prepared pie crust.
Use a spatula to spread it evenly across the crust, reaching the edges.
Keep the filling warm while preparing the meringue. A warm filling helps the meringue adhere to the pie and reduces the chance of a gap forming between the layers.
Step 4: Prepare the Fluffy Meringue
Place the egg whites in a clean, dry mixing bowl. Make sure there is no egg yolk in the whites, as even a small amount of fat can interfere with whipping.
Add the cream of tartar.
Using an electric mixer, beat the egg whites on medium speed until they become foamy.
Gradually add the sugar, one tablespoon at a time, while continuing to beat.
Increase the mixer speed and beat until the mixture forms glossy, stiff peaks. When you lift the beaters, the meringue should hold its shape without collapsing.
Add the vanilla extract and gently mix until incorporated.
Avoid overbeating, which can make the meringue grainy or unstable.
Step 5: Spread the Meringue Over the Pie
Spoon the meringue over the warm lemon filling.
Begin in the center and spread it toward the edges.
Make sure the meringue touches the crust all the way around. This helps seal the topping to the edges and reduces shrinking during baking.
Use the back of a spoon to create decorative swirls and soft peaks across the surface.
These little peaks will turn beautifully golden in the oven, giving the pie its classic homemade appearance.
Step 6: Bake Until Golden
Reduce the oven temperature to 350°F (175°C).
Place the pie in the oven and bake for approximately 12–18 minutes, or until the meringue develops a light golden-brown color.
Keep an eye on the topping during the final minutes because meringue can brown quickly.
Remove the pie from the oven and place it on a wire rack.
For food safety, the meringue should be made with pasteurized egg whites or heated sufficiently to make the egg whites safe to eat. If using a standard egg-white meringue, follow a tested recipe that specifies a safe heating method rather than relying on browning alone.
Step 7: Cool the Pie Before Slicing
Allow the pie to cool on a wire rack.
Lemon meringue pie needs several hours to cool and set properly before slicing. Cutting it while it is still warm can cause the lemon filling to run.
Once cooled, refrigerate the pie promptly. Because it contains eggs, keep it refrigerated at 40°F (4°C) or below, and do not leave it at room temperature for more than two hours.
For the cleanest slices, use a sharp knife and wipe the blade between cuts.
Each slice should reveal three delicious layers: a golden crust, a vibrant lemon filling, and a cloud of fluffy meringue.
Tips for the Best Lemon Meringue Pie
Use fresh lemons. Freshly squeezed lemon juice gives the filling a bright, natural citrus flavor. Bottled juice may taste different and can affect the final result.
Measure the cornstarch carefully. The right amount helps the filling thicken without becoming overly firm or watery.
Separate eggs carefully. Keep all traces of yolk out of the egg whites so the meringue can whip properly.
Spread the meringue over warm filling. This encourages the layers to adhere to one another.
Seal the meringue to the crust. Make sure the topping reaches the edges of the pie to help prevent shrinking and separation.
Allow enough cooling time. A properly cooled pie is easier to slice and serve.
Store leftovers safely. Cover the cooled pie loosely and refrigerate. For the best texture, enjoy it within two to three days.
Why Everyone Loves Homemade Lemon Meringue Pie
Lemon meringue pie is a wonderful example of how simple ingredients can create an extraordinary dessert.

Frequently Asked Questions
Why does my lemon filling turn runny?
The filling may not have cooked long enough to activate the cornstarch properly, or the pie may have been sliced before it had time to cool. Follow the cooking instructions carefully and allow several hours for the filling to set.
Why does my meringue shrink?
Meringue may shrink if it has not been spread to the edges of the crust, if it is unstable, or if it is not baked correctly. Sealing the topping to the crust helps reduce this problem.
Can I make lemon meringue pie a day ahead?
Yes, although the meringue is often at its best on the day it is made. Prepare the pie ahead if needed, cool it properly, and refrigerate it. Some moisture may develop on the meringue during storage.
Can I use bottled lemon juice?
You can, but freshly squeezed lemon juice generally provides a brighter flavor. Fresh lemon zest also adds a wonderful citrus aroma.
How do I know when the pie is ready?
The meringue should be lightly golden and set, while the lemon filling should be thick enough to hold its shape after the pie has cooled. Follow a reliable recipe with appropriate egg-safety instructions.
