Classic lemon meringue pie layers a flaky crust, a tart and silky lemon filling, and a tall golden meringue that bakes into soft swirls.
The steps look long, but each one is simple, and the pie rewards a little patience with clean slices and a bright lemon flavor that stays fresh.

Why This Classic Lemon Meringue Pie Recipe Works
Cooking the filling with cornstarch and tempered egg yolks gives a smooth custard that sets firm enough to slice while staying silky on the tongue.
Spreading the meringue over the warm filling and sealing it to the crust edge helps stop shrinking, and the oven turns the peaks golden and just crisp.
Chilling the finished pie for several hours firms up the filling so each slice holds a clean edge and the lemon flavor mellows into balance.
Ingredients for Classic Lemon Meringue Pie
- 1 homemade 9 inch pie crust, chilled for at least 2 hours
- 5 large egg yolks and 5 large egg whites, separated
- 1 cup plus 1/3 cup water
- 1 cup granulated sugar for the filling and 1/2 cup for the meringue
- 1/3 cup cornstarch
- 1/4 teaspoon salt for the filling and a pinch for the meringue
- 1/2 cup fresh lemon juice and 1 tablespoon lemon zest
- 2 tablespoons softened unsalted butter
- 1/2 teaspoon cream of tartar
Egg yolks. Yolks thicken the filling into a rich custard, and they need to be tempered with warm filling so they do not scramble.
Cornstarch. Cornstarch sets the filling so it holds a slice, and it needs to bubble in the pan to reach full thickening power.
Lemon juice and zest. Fresh juice brings the tart flavor while zest adds fragrant oils, so the filling tastes bright instead of flat.
Egg whites and cream of tartar. Whites whip into the meringue, and cream of tartar stabilizes them so the peaks stay tall and glossy.
Butter. A little butter whisked into the hot filling gives it a smooth, glossy finish and rounds out the tartness.
How to Make Classic Lemon Meringue Pie
1. Blind bake the crust Chill the crust, then heat the oven to 375 degrees F, line the crust with parchment and weights, and bake until golden and set.
2. Lower the oven Reduce the oven temperature to 350 degrees F while you make the filling, since the meringue bakes at that heat.
3. Cook the filling Whisk 1 cup of the sugar, cornstarch, salt, water, lemon juice, and zest over medium heat for 3 to 5 minutes until thick and bubbling.
4. Temper the yolks Whisk a few spoonfuls of the hot filling into the yolks, pour them back into the pan, and cook 1 to 2 minutes more.
5. Finish the filling Remove the pan from the heat, whisk in the butter until glossy, and pour the hot filling into the warm crust.
6. Whip the meringue Beat the whites with cream of tartar to soft peaks, then add the remaining sugar and a pinch of salt gradually until stiff and glossy.
7. Bake and chill Spread the meringue to the crust edge, swirl it, and bake 20 to 25 minutes until golden, then cool for 1 hour and chill for 4 hours.
How to Serve Classic Lemon Meringue Pie
Slice the pie cold and serve it with lemon layer cake for a lemon lovers dessert table, plus a pitcher of fresh pineapple lemonade to match. Vanilla bean creme brulee and fresh peach lemonade round out the menu for guests who want something different.
How to Store and Reheat Classic Lemon Meringue Pie
Cool the pie at room temperature for 1 hour, then refrigerate it loosely covered for up to 3 days. Skip the freezer, since the meringue weeps and the filling turns watery after thawing.
Tips and Variations for Classic Lemon Meringue Pie
Check the meringue temperature. Bake the meringue until it is deep golden and reaches 160 degrees F in the center so the egg whites cook through.
Flag the allergens. The pie contains eggs, wheat, and milk from the butter, so check every label and tell guests before serving.
Temper slowly. Add the hot filling to the yolks a spoonful at a time while whisking so the eggs warm gently and stay smooth.
Seal the edges. Spread the meringue all the way to the crust so it grips the pastry and does not shrink away as it bakes.
Use a clean bowl. Any trace of fat or yolk keeps the whites from whipping, so wipe the bowl dry and clean before you start.
Tent if needed. If the meringue browns too fast, lay a loose piece of foil over the pie for the rest of the bake.
Cut with a wet knife. Dip a sharp knife in hot water and wipe it between slices so the meringue cuts cleanly.
Check trusted guidance. For general advice on handling eggs and storing egg based desserts, read the Montana State University Extension egg fact sheet before you begin.
Frequently Asked Questions About Classic Lemon Meringue Pie
Why does my classic lemon meringue pie weep?
Weeping happens when the meringue is under baked or does not touch the crust, so seal it to the edge and bake until golden.
Can I make classic lemon meringue pie a day ahead?
Yes, it holds well for a day when chilled and loosely covered, and the filling slices more cleanly after a long chill.
How do I get tall peaks on classic lemon meringue pie?
Use a clean bowl, add the sugar gradually, and beat until the whites are stiff and glossy so the peaks hold their height in the oven.
Can I use bottled lemon juice?
Fresh juice gives a brighter flavor, so bottled juice works only if you need it, and the pie will taste flatter.
Why did my filling not set?
The filling needs to bubble in the pan so the cornstarch thickens fully, so keep whisking over the heat until it is thick and bubbling.
