Made with ordinary limes, this “Key lime” pie tastes every bit as authentic as the real deal — plus it’s easier to make.
Ingredients You’ll Need To Make Key Lime Pie
- You’ll need 8 to 10 limes total for this recipe. Choose plump limes that give a little when you squeeze them; they will be easier to juice. You should get about 2 tablespoons of juice from each lime. Be sure to zest the limes before you squeeze the juice from them, as it’s near impossible to do afterward.
- Sweetened condensed milk is canned milk from which water has been removed, and sugar has been added. Be sure not to confuse it with evaporated milk, which is usually sold right alongside.
- With no eggs, it may be hard to believe that this pie will set, but have faith- it will.
How To Make Key Lime Pie
Step 1: Make The Crust
Combine the graham cracker crumbs, brown sugar and melted butter in a mixing bowl. Stir with a fork first, and then your hands until the mixture is well combined.
Using your fingers and the bottom of a measuring cup or glass, press the crumbs firmly into the bottom and up the sides of a 9-in deep-dish pie pan. The crust should be about 1/4-in thick. (Hint: do the sides first.)
Bake the crust for 10 minutes, or until lightly browned. Then let the crust cool a bit while you make the filling.
Step 2: Make the Filling
Begin by zesting the limes.
It’s best to use a rasp grater, which is a long, skinny tool that works well for grating hard cheeses and zesting citrus.
Juice the limes using a citrus reamer, then combine the juice with the sweetened condensed milk, yogurt, and lime zest.
Whisk to combine.
Pour the filling into the cooked graham cracker crust.
Bake for about 15 minutes, or until the filling is almost set.
Let the pie cool at room temperature for 30 minutes, then place in the refrigerator to chill thoroughly, about 3 hours.
Step 3: Make the Topping
In the bowl of an electric mixer fitted with the whisk attachment (or beaters), beat the heavy cream until soft peaks form. Add the confectioners’ sugar and beat until medium peaks form. (Alternatively, the cream can be beaten by hand with a whisk.) Top the chilled pie with whipped cream and decorate with lime slices and zest.

Ingredients
For the Crust
- 1½ cups finely crushed graham cracker crumbs, from about 12 whole graham crackers
- ⅓ cup packed light brown sugar
- 4 tablespoons unsalted butter, melted
For the Filling
- Two 14-oz cans sweetened condensed milk
- 1 cup plain Greek yogurt (2% or whole milk)
- 1 tablespoon grated lime zest
- ¾ cup fresh lime juice
For the Topping
- 1 cup cold heavy cream
- 2 tablespoons confectioners’ sugar
- 1 teaspoon grated lime zest
- 8 to 10 thin lime slices
Instructions
For the Crust
- Preheat oven to 375 °F and set an oven rack in the middle position.
- In a medium bowl, combine the graham cracker crumbs, brown sugar, and melted butter; stir with a fork first, and then your hands until the mixture is well combined. Using your fingers and the bottom of a glass or dry measuring cup, press the crumbs firmly into the bottom and up the sides of a 9 x 1.5-inch (deep-dish) pie pan. The crust should be about ¼-inch thick. (Tip: do the sides first.)
- Bake for 10 minutes, until just slightly browned. Let the crust cool on a wire rack.
For the Filling
- Lower the oven temperature to 350°F.
- In a large bowl, whisk together the sweetened condensed milk, yogurt, lime zest, and lime juice. Pour the thick mixture into the warm graham cracker crust. Bake for 15 minutes, until the filling is almost set; it should wobble a bit. Let cool at room temperature for 30 minutes, then place in the refrigerator to chill thoroughly, about 3 hours.
For the Topping
- In the bowl of an electric mixer, beat the heavy cream until soft peaks form. Add the confectioners’ sugar and beat until medium peaks form. Top the pie with the whipped cream. Decorate with the lime zest and lime slices. Store the pie in the refrigerator until ready to serve. Slice the pie into wedges, wiping your knife clean between slices, and serve cold.
- Make-Ahead Instructions: You can make the crust a day ahead of time, but the filling should be added on the day of serving, otherwise the crust will get soggy.
