This lemon pie recipe is a baked condensed milk pie: one 14 ounce can of sweetened condensed milk, 4 egg yolks, ½ cup fresh lemon juice and 1 tablespoon zest, whisked together and poured into a pre-baked 9 inch crust. It bakes at 350°F for just 15 to 18 minutes, chills for at least 3 hours, and cuts into 12 slices under a cloud of whipped cream.
The bowl does most of the work. The lemon juice thickens the condensed milk as you whisk, and the short bake sets the yolks. That is why it slices clean and cold, with a bright, sharp lemon flavor and a creamy middle.

Sweetened condensed milk is milk cooked down with a lot of sugar. When you add an acid like lemon juice, its milk proteins tighten and the mixture turns noticeably thicker within a minute of whisking. You can feel the whisk drag. That thickening is the first half of the set.
The egg yolks are the second half. They add body and richness, and in 15 to 18 minutes at 350°F they cook through just enough to firm the filling. For the juice, use all ½ cup. Weak or watered down juice gives a softer, sweeter filling that may not hold a clean edge.
What Goes in the Condensed Milk Filling
- Sweetened condensed milk, 1 can (14 oz): sweetness and the creamy base.
- Egg yolks, 4 large: body and the final set. Save the whites for meringues or an omelet.
- Fresh lemon juice, ½ cup: from about 3 to 4 lemons.
- Lemon zest, 1 tablespoon finely grated: most of the lemon aroma lives here.
- Salt, ¼ teaspoon: keeps the sweetness in check.
- Yellow gel food coloring, 1 to 2 drops (optional): the filling is naturally pale, so this only warms the color. Gel will not thin it the way liquid coloring can.
- Topping: 1 cup heavy whipping cream, 2 tablespoons powdered sugar and ½ teaspoon vanilla (optional).
Any brand of sweetened condensed milk works the same here: Carnation, Eagle Brand or a store brand, as long as the can says sweetened condensed. Evaporated milk sits on the same shelf and looks similar, but it has no added sugar and will not thicken with lemon. Zest only the bright yellow skin. The white pith underneath is bitter.
Pastry Shell or Graham Cracker Crust?
I have made this pie with both. A graham cracker crust is quicker and sweeter, and you just press the crumbs into the tin with the bottom of a measuring cup and bake it for a few minutes. It softens after a day in the fridge, though, so it suits a pie you will finish the same day.
A blind baked butter pie crust takes longer but stays crisp for 2 to 3 days and cuts into neat wedges. Bake it at 375°F for 15 to 18 minutes, until golden and dry, and let it cool completely. Whichever crust you pick, it has to be fully baked before the filling goes in. The filling only spends about 15 minutes in the oven, which is not enough to cook a raw crust underneath it.
Mixing and Baking the Lemon Filling
Heat the oven to 350°F. In a medium bowl, whisk the yolks, condensed milk, lemon juice, zest, salt and a drop of coloring until smooth and creamy. Whisk steadily, not hard. Thick and glossy, not foamy.
Pour it into the cooled crust. Tap the pan on the counter a couple of times to bring up bubbles, then smooth the top with a spatula.
Bake for 15 to 18 minutes. The edges should look set and matte, while the center still has a very slight jiggle when you nudge the pan. Take it out then. The fridge does the rest. If you overbake, the edges turn chalky and the top can crack. Cool the pie on the counter for about 30 minutes, then chill it for at least 3 hours. Overnight is better: the slices come out cleaner and the lemon tastes deeper.
When the Lemon Filling Goes Wrong
- Runny after chilling: it was pulled too early, chilled too briefly, or made with evaporated milk or weak bottled juice. Give it the full 3 hours before deciding; most soft pies firm up overnight.
- Grainy or curdled texture: the pie baked too long or too hot and the yolks scrambled. Stick to 350°F and stop at the slight jiggle.
- Beads of moisture on top: it was covered while still warm and condensation dripped onto it. Chill uncovered until cold, then cover loosely with foil.
- Bitter edge to the flavor: white pith got into the zest. Grate lightly and turn the lemon often.
- Soggy bottom: the crust was raw, underbaked or still warm when filled.
Whipped Cream Topping for Lemon Pie
Whip the cream with the powdered sugar right before serving, until it holds soft peaks that bend over at the tip. Vanilla is optional. I usually skip it. It gets in the way of the lemon.
Pipe swirls around the edge or spread it in loose dollops, then finish with a few curls of zest or thin lemon slices. If the pie has to wait a few hours after topping, a stabilized whipped cream frosting holds its shape longer. Prefer meringue? The same lemon idea with a toasted top is my lemon meringue pie.
Lemon Pie vs Key Lime and North Carolina Lemon Pie
All three share the same base of sweetened condensed milk, egg yolks and citrus juice, baked briefly and served cold. A key lime pie swaps in lime juice and usually sits in a graham cracker crust. The North Carolina lemon pie uses a salty crushed cracker crust that plays against the sweet filling. This one keeps a flaky pastry shell and a whipped cream top, so it eats more like a cream pie.
Chilling Ahead and Keeping Leftovers
Make the pie the day before and add the whipped cream just before serving. Leftovers keep in the fridge for up to 3 days, loosely covered. Serve it well chilled and cut with a thin knife wiped clean between slices.
For a picnic or party, carry it in a cooler and keep it out of the fridge for no more than about 2 hours. This is an egg and dairy pie, so it does not belong in the sun. Without the topping, the pie also freezes well for up to 1 month; thaw it overnight in the fridge and top it fresh.
Condensed Milk Lemon Pie Questions
Can I make a 3 ingredient lemon pie with condensed milk?
Yes. Condensed milk, egg yolks and lemon juice in a ready crust is the core of this recipe. The zest, salt and topping make it taste better, but the pie sets without them.
Can I use Cool Whip instead of whipped cream?
Yes. Spread thawed whipped topping over the cold pie just before serving. It holds up longer than plain whipped cream but tastes sweeter and less fresh.
Do I have to bake lemon pie with condensed milk?
Bake this one. The 15 minute bake cooks the egg yolks and gives the firmest slice. For a no-bake pie without eggs, try this frozen lemonade pie or the lemon lime icebox pie.
Can I use bottled lemon juice?
It will set, but fresh juice tastes brighter and you need the lemons for zest anyway. Three to four lemons give you both.
More lemon bakes live in my lemon dessert recipes, including a raspberry lemon chiffon pie. Leave a comment if you make this one, or ask if you need help with the crust or bake time.
Lemon Pie Recipe
This lemon pie recipe is a baked lemon pie with sweetened condensed milk, egg yolks, fresh lemon juice and lemon zest in a pre-baked 9 inch pie crust, topped with whipped cream. The filling takes about 10 minutes to mix, bakes at 350°F for 15 to 18 minutes and chills for at least 3 hours, giving 12 creamy, tangy slices. Lemon juice thickens the condensed milk as you whisk and the yolks set it in the oven, so this condensed milk lemon pie slices clean without gelatin or cornstarch. Any brand of sweetened condensed milk works, such as Carnation or Eagle Brand, but not evaporated milk. Serve it for Easter, summer cookouts or a make-ahead dinner dessert. Keeps 3 days in the fridge.
Ingredients
- FOR THE LEMON PIE FILLING
- 1 (14 oz) can sweetened condensed milk
- 4 large egg yolks
- ½ cup freshly squeezed lemon juice (from about 3–4 lemons)
- 1 tablespoon finely grated lemon zest
- ¼ teaspoon salt
- 1–2 drops yellow gel food coloring (optional but recommended for a vibrant look)
- 1 pre-baked 9-inch pie crust (homemade or store-bought)
- FOR THE WHIPPED TOPPING
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- ½ teaspoon vanilla extract (optional)
Instructions
- PREPARE THE CRUST: If your crust isn’t already baked, blind bake it at 375°F (190°C) for 15–18 minutes until golden and crisp. Let it cool completely before adding the filling.
- MIX THE LEMON FILLING: In a medium mixing bowl, whisk together the egg yolks, sweetened condensed milk, lemon juice, lemon zest, salt, and food coloring. Start with 1 drop of yellow food coloring and increase to 2 if you want a more vibrant hue. Whisk until smooth, creamy, and fully combined.
- POUR INTO CRUST: Pour the lemon mixture into the cooled pie crust. Tap the pan gently on the counter to remove any air bubbles and smooth the top with a spatula.
- BAKE: Bake the pie at 350°F (175°C) for 15–18 minutes. The filling should look set with a very slight jiggle in the center. Do not overbake—it will firm up as it cools.
- COOL AND CHILL: Let the pie cool at room temperature for about 30 minutes, then refrigerate for at least 3 hours, preferably overnight. This allows the filling to set into a creamy, sliceable texture.
- WHIP THE CREAM: When ready to serve, whip the heavy cream with powdered sugar and vanilla extract (if using) until soft peaks form. Use a spoon or piping bag to add it to the pie.
- DECORATE AND SERVE: Top the chilled pie with swirls or dollops of whipped cream. You can also garnish with a bit of lemon zest or thin lemon slices for flair.
Notes
Use sweetened condensed milk, not evaporated milk, and fresh lemon juice; both are needed for the filling to thicken and set. The crust must be fully baked and cooled before filling. Bake only until the edges are set and the center has a slight jiggle; overbaking makes the edges chalky or grainy. Cool 30 minutes, then chill uncovered until cold before covering, so condensation does not bead on top. Chill at least 3 hours, ideally overnight. Add whipped cream just before serving. Store in the refrigerator for up to 3 days. Without topping, the pie freezes for up to 1 month; thaw overnight in the fridge. For the food coloring, gel-based types give color without thinning the filling.
