This old fashioned lemon meringue pie pairs a bright lemon custard with a tall, toasted cloud of meringue, and it has been a favorite at family tables for generations. The filling is smooth, tart, and sweet in balance.
It starts with a stovetop filling made from lemon juice, sugar, cornstarch, egg yolks, and butter, poured into a baked crust and topped with whipped egg whites. A short bake sets the peaks, and a long chill gives clean, neat slices.

Why This Old Fashioned Lemon Meringue Pie Recipe Works
The filling is thickened with cornstarch and enriched with egg yolks, so it sets firm enough to slice cleanly while staying silky on the tongue. A full measure of fresh lemon juice keeps the flavor sharp and bright.
The meringue is whipped with sugar until soft peaks form, then spread over the warm filling so it seals against the crust. That seal helps stop the shrinking and weeping that ruin so many meringue pies.
Everything comes together in one saucepan, one bowl, and one pie plate. A store bought crust saves time, yet a homemade crust works just as well, so the pie fits busy weeks and slow weekends equally.
Ingredients for Old Fashioned Lemon Meringue Pie
- For the filling: fresh lemon juice, water, sugar, cornstarch, egg yolks, and unsalted butter, cooked together on the stove until thick enough to coat a spoon.
- For the meringue and crust: egg whites at room temperature, sugar, a little vanilla extract, and one baked nine inch pie crust, either store bought or homemade.
Lemon juice. Squeeze fresh lemons for the filling, since bottled juice tastes flat and thin once it is cooked with the sugar.
Cornstarch. This starch thickens the filling, and it needs a full minute of gentle boiling to lose any raw taste and reach full strength.
Egg yolks. Yolks give the filling a rich color and a smooth, custard like body, but they must be fully cooked in the hot mixture.
Egg whites. Whites whip higher at room temperature, and a clean, dry bowl without any trace of yolk or grease helps them build volume.
Butter. A small amount stirred into the hot filling adds shine and a rounded flavor that softens the sharp lemon edge.
How to Make Old Fashioned Lemon Meringue Pie
1. Bake the crust. Bake the pie crust until golden and fully cooled, because a warm crust will turn the filling runny and soggy before it ever sets.
2. Cook the filling. Whisk the juice, water, sugar, and cornstarch in a saucepan over medium heat, stirring constantly until the mixture thickens and bubbles, then boil for one minute.
3. Add the yolks. Whisk a spoonful of hot filling into the yolks, stir them back into the pan, and cook until the filling reaches 160 F, then whisk in the butter.
4. Fill the pie. Pour the hot filling into the cooled crust and smooth the top, keeping it warm while you whip the meringue so the two layers bond.
5. Whip the meringue. Beat the egg whites until frothy, add the sugar a little at a time, and continue until soft peaks form and the meringue looks glossy and smooth.
6. Top and bake. Spread the meringue over the warm filling all the way to the crust edge, then bake at 350 degrees F until the peaks turn golden brown. Cool, then chill until firm before slicing.
How to Serve Old Fashioned Lemon Meringue Pie
Slice with a hot, wet knife so the meringue cuts cleanly, and serve the pie chilled. A cup of black coffee or a glass of fresh peach lemonade suits it well, while passion fruit ice cream, a fruit pavlova, and classic cheesecake round out a dessert table.
How to Store and Reheat Old Fashioned Lemon Meringue Pie
Keep the pie in the refrigerator, uncovered at first so the meringue stays dry, then loosely tented with foil for up to three days. Cool the pie within two hours of baking, and do not freeze it, because the filling turns watery and the meringue weeps. Slice only what you plan to serve.
Tips and Variations for Old Fashioned Lemon Meringue Pie
Seal the edge. Spread the meringue onto the warm filling and press it against the crust all the way around to stop shrinking.
Whip with care. Stop whipping at glossy soft peaks, since overbeaten whites turn grainy and weep liquid onto the filling.
Cook the filling fully. Bring the filling to a boil and cook until it reaches 160 F so the yolks are safe and the starch is set.
Use clean tools. Wipe the bowl and beaters dry, and make sure no yolk slips into the whites, because fat stops them from rising.
Flag the allergens. This pie contains wheat, egg, and milk, so label it clearly when serving guests with food allergies.
Skip the raw taste. Do not taste the raw meringue mixture, and use pasteurized egg whites for young children, pregnant guests, older adults, and anyone with a weak immune system.
Try a variation. Fold a little lemon zest into the filling for more aroma, or pipe the meringue into swirls for a bakery look.
Check trusted guidance. Read the Montana State University Extension egg fact sheet for safe egg handling.
Frequently Asked Questions About Old Fashioned Lemon Meringue Pie
How do you keep an old fashioned lemon meringue pie from getting watery?
Cook the filling until it boils for a full minute, seal the meringue to the crust, and chill the pie completely before slicing.
Can you make an old fashioned lemon meringue pie the day before?
Yes. Bake it, cool it for one hour, and chill it overnight. The meringue looks freshest on the first day, though the pie still slices and tastes good a day later.
What makes an old fashioned lemon meringue pie filling set firm?
Cornstarch and egg yolks do the work, but only if the mixture boils for a full minute and then cooks to 160 F.
Can I use bottled lemon juice?
Fresh juice tastes brighter, though bottled juice works in a pinch if you add a little grated zest.
Why is my meringue weeping?
Beads of liquid form when the whites are underbaked or the meringue was spread on a cold filling. Spread it over warm filling and bake until golden.
