How to Make Key Lime Pie
Step 1: Prepare the Crust
Combine the melted butter and sugar in a bowl. Mix in the graham cracker crumbs until fully combined. Press the mixture firmly into a 9-inch pie plate. Chill or bake at 375°F for 5 minutes to set the crust.
Step 2: Get Ready
Preheat your oven to 350°F. Zest the key limes to get 2 teaspoons of zest and juice them for the filling.
Step 3: Mix the Filling
Whisk the egg yolks in a bowl until they thicken. Slowly add the sweetened condensed milk while mixing. Incorporate the key lime juice and zest until the mixture is smooth and well-blended.
Step 4: Bake the Pie
Pour the filling into the prepared crust. Bake it for 15 minutes until set. Allow it to cool to room temperature, then refrigerate for at least 3 hours to let it firm up.
Step 5: Finish and Serve
Once chilled, garnish with whipped topping and lime slices if you like. Slice it up, serve, and enjoy this refreshing dessert!

Pro Tips from My Kitchen
✓ Make it Extra Crunchy – Pre-bake the crust a bit longer for a firmer base if you prefer more crunch in every bite.
✓ Zest Before Juicing – Always zest your limes before juicing for ease and to get the most aroma from the zest.
✓ Store Wisely – This pie keeps well in the fridge. Cover it loosely with plastic wrap to prevent it from picking up any fridge odors.
✓ Adjust the Sweetness – If you prefer a less sweet pie, slightly reduce the amount of condensed milk.
✓ Presentation Matters – Use fresh lime slices or zest as a decorative touch for a professional look.
What Makes This Recipe Work
- The combination of fresh key lime juice and zest injects a burst of citrus flavor that stands out against the sweetness of the condensed milk. This balance is key to the pie's refreshing taste.
- The graham cracker crust provides a crunchy, buttery base that complements the creamy filling, making each bite a delicious mix of textures and flavors.
- Egg yolks are essential, giving the filling its rich, custard-like texture while helping to hold it together after baking.
