Ingredients

For the Crust

  • 1 ½ cups graham cracker crumbs
  • ⅓ cup granulated sugar
  • 6 tablespoons unsalted butter, melted

For the Filling

  • 1 can sweetened condensed milk
  • ½ cup fresh lime juice
  • 1 tablespoon lime zest
  • 3 large egg yolks

For Topping

  • Whipped cream
  • Lime zest or lime slices for garnish

Cooking Directions

The graham cracker crust is baked until lightly golden, then filled with a creamy lime mixture made from condensed milk, egg yolks, and fresh lime juice. The pie is baked briefly to set the filling and then chilled until firm and creamy.

Step-by-Step Preparation Method

  1. Preheat the oven to 175°C.
  2. In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter until evenly mixed.
  3. Press the mixture firmly into the bottom and sides of a pie dish.
  4. Bake the crust for 8 to 10 minutes until lightly golden. Remove and allow it to cool slightly.
  5. In another bowl, whisk together sweetened condensed milk, lime juice, lime zest, and egg yolks until smooth.
  6. Pour the filling into the prepared crust.
  7. Bake for 12 to 15 minutes, just until the center is set but still slightly soft.
  8. Remove from the oven and let the pie cool at room temperature.
  9. Refrigerate for at least 2 to 3 hours before serving.
  10. Top with whipped cream and garnish with lime zest or slices before serving.

How to Serve

Serve Key Lime Pie well chilled for the best texture and flavor. Slice using a sharp knife wiped clean between cuts for neat portions. It pairs beautifully with whipped cream and a light citrus garnish.

Recipe Tips

  • Use fresh lime juice for the brightest and most authentic flavor.
  • Do not overbake the filling, as it will continue to set while cooling.
  • Chill the pie thoroughly before slicing to ensure clean cuts.
  • Taste the filling before baking and adjust lime juice if you prefer extra tang.
