🧾 Ingredients for Key Lime Pie

👨‍🍳 How to Make Key Lime Pie (Step-by-Step)

✅ Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Gather all the ingredients and place the graham cracker crust on a baking sheet.

✅ Step 2: Mix the Filling

In a large mixing bowl, combine the condensed milk, key lime juice, sour cream, and lime zest. Stir until the mixture is completely smooth and well blended.

✅ Step 3: Fill and Bake

Pour the mixture into the crust and gently smooth the top. Bake in the preheated oven for 5 to 8 minutes, just until tiny pinhole bubbles start forming on the surface. The filling should look set but still jiggle slightly—do not allow it to brown.

✅ Step 4: Cool and Chill

Remove the pie from the oven and transfer it to a wire rack to cool. Then refrigerate the pie for at least 1 hour (longer is better) to let the filling set completely.

✅ Step 5: Garnish and Serve

Before serving, garnish with whipped cream, lime zest, or thin lime slices for an elegant, tropical look. Slice, serve, and enjoy your homemade key lime pie!


🧊 How to Store Key Lime Pie

Wrap the cooled pie tightly in plastic wrap or foil. Refrigerate for up to 3 days. Serve chilled for best flavor.


❄️ Can You Freeze Key Lime Pie?

Absolutely! Freeze your pie in an aluminum pan for up to 3 months. Wrap it tightly with plastic wrap and a layer of foil. Thaw overnight in the fridge before serving. Add garnishes after thawing.
