Ingredients

  • 1 1/2 cups graham cracker crumbs
  • 6 tablespoons unsalted butter, melted
  • 1/4 cup granulated sugar
  • 3 large egg yolks
  • 14 ounces sweetened condensed milk
  • 2/3 cup fresh lime juice
  • 1 tablespoon lime zest
  • 1 cup heavy cream, whipped, for topping

Directions

  1. Heat the oven to 350F. Stir the graham crumbs, melted butter, and sugar, then press firmly into a 9-inch pie plate. Bake 8 minutes and set aside.
  2. Whisk the egg yolks and lime zest in a bowl until lightened, about 2 minutes.
  3. Whisk in the condensed milk, then the lime juice, until smooth and slightly thickened.
  4. Pour the filling into the crust and bake 12 to 15 minutes, until the center is just set with a slight jiggle.
  5. Cool to room temperature, then chill at least 3 hours or until firm.
  6. Top with whipped cream and extra lime zest before serving.

Tips and variations

  • Use fresh lime juice for the brightest flavor. Bottled key lime juice works if fresh is not available.
  • Chill the pie at least 3 hours so it sets firm enough to slice.
  • Do not overbake. The center should still jiggle slightly when you pull it.
  • Top with whipped cream just before serving so it stays fresh.

Common questions

Do I need real key limes
Regular limes work well and are easier to find. Key limes are more tart and aromatic, but the pie is excellent either way.
Why is my key lime pie runny
Runny filling means underbaking or too little acid. Bake until the center just sets and use enough fresh lime juice.
Can I make key lime pie ahead
Yes. It is a great make-ahead dessert. Bake and chill it a day before, then add whipped cream before serving.
How long does it keep
Covered in the fridge, the pie keeps about 4 days. Add the whipped cream topping fresh each time you serve it.
