There are few desserts that can capture the essence of summer quite like a classic key lime pie. In this article, I will share the BEST EVER recipe for a classic key lime pie that will have your taste buds singing with delight.

1. Classic Key Lime Pie


  • 1 (14 oz) can sweetened condensed milk
  • 4 egg yolks
  • 3/4 cup fresh key lime juice (about 20-25 key limes)
  • 1 (9-inch) pre-baked graham cracker pie crust
  • Whipped cream, for topping (optional)
  • Lime zest, for garnish (optional)


Preheat your oven to 350°F (175°C).

In a medium bowl, whisk together the sweetened condensed milk and egg yolks until smooth and well combined.

Slowly pour in the key lime juice, whisking constantly until the mixture is fully incorporated and has a creamy, custard-like consistency.

Pour the key lime filling into the pre-baked graham cracker pie crust, spreading it evenly.

Bake the pie in the preheated oven for 15-18 minutes, or until the center is slightly jiggly but set. The edges may start to turn golden brown.

Remove the pie from the oven and let it cool completely at room temperature, then refrigerate for at least 4 hours, or up to 24 hours, before serving.

Just before serving, top the chilled pie with freshly whipped cream, if desired. Garnish with a generous amount of freshly grated lime zest.


  • Use the freshest key limes you can find for the most intense and authentic flavor. If key limes are not available, you can substitute regular Persian limes, but the flavor will be slightly less tart.
  • Make sure to thoroughly whisk the sweetened condensed milk and egg yolks until the mixture is smooth and creamy before adding the lime juice.
  • Chilling the pie for at least 4 hours, or up to 24 hours, is crucial for the filling to set properly and achieve the desired texture.
  • For a more pronounced lime flavor, you can add 1-2 teaspoons of grated lime zest to the filling.
  • Serve the key lime pie chilled for the best taste and texture.


  • For a lighter version, you can top the pie with a meringue topping instead of whipped cream.
  • Sprinkle toasted coconut flakes on top of the whipped cream or meringue for a tropical twist.
  • Use a homemade graham cracker crust for an extra-crunchy base.

This classic key lime pie recipe is truly the best. The combination of the sweet and creamy condensed milk, the tart and tangy key lime juice, and the rich, custardy filling in a crisp graham cracker crust is simply irresistible.
