Step-by-Step Preparation of Key Lime Pie
Creating a delicious key lime pie is both fun and rewarding. Packed with a citrusy punch, this dessert is a perfect end to any meal! Let’s walk through the steps to prepare a delectable pie that will impress your friends and family.
Prepare the crust
Start by preheating your oven to 375°F. In a medium bowl, blend 1½ cups of finely crushed graham cracker crumbs, ⅓ cup of packed light brown sugar, and 4 tablespoons of melted unsalted butter. Mix with a fork until combined; then use your hands to ensure everything is mixed well. It’s essential to create a cohesive mixture so the crust holds together beautifully.
Next, press this mixture firmly into the bottom and up the sides of a 9-inch deep-dish pie pan, making sure it reaches about ¼-inch thick. For best results, do the sides first, utilizing your fingers and the base of a cup to achieve a sturdy crust. Bake for about 10 minutes until it's just slightly golden. Let it cool on a wire rack while you prepare the filling.
Make the filling
Once your crust has cooled, reduce the oven temperature to 350°F. In a large mixing bowl, whisk together two cans of sweetened condensed milk, 1 cup of plain Greek yogurt, 1 tablespoon of grated lime zest, and ¾ cup of fresh lime juice. This combination creates a creamy, tangy filling that’s a hallmark of any key lime pie. Pour the thick mixture into your warm graham cracker crust, then bake it again for 15 minutes. It should set but still have a slight wobble in the center. Allow it to cool at room temperature for 30 minutes, then pop it in the refrigerator to chill thoroughly for at least 3 hours.
Chill the pie
Chilling is crucial for a luscious key lime pie. It allows the flavors to meld beautifully and ensures a perfect texture. If you can wait until the next day for serving, you’ll find that the pie tastes even better after resting overnight. But if you’re eager, a minimum of 3 hours in the fridge should suffice!
Prepare the whipped topping
While your pie is chilling, let’s whip up some dreamy topping. In the bowl of an electric mixer, beat 1 cup of cold heavy cream until soft peaks form. Gradually add 2 tablespoons of confectioners’ sugar and continue mixing until you achieve medium peaks. This step is where the pie really elevates— a light and airy topping to complement the creamy filling. Once the topping is ready, feel free to lavish it onto your pie, and don’t forget to sprinkle some extra lime zest on top or place thin lime slices for that perfect finishing touch.
Now, your key lime pie is ready to impress! Just remember to slice it gently, wiping your knife clean between cuts. Enjoy this delightful dessert chilled and share it with those you love!

Variations on Key Lime Pie
Coconut Key Lime Pie
Give your key lime pie a tropical twist by incorporating coconut! Substitute half of the Greek yogurt with coconut cream for a rich, creamy texture. For an added flavor bump, fold in toasted coconut flakes before pouring the mixture into your crust. This delightful variation adds an exotic flair that will transport you to a sunny beach paradise.
Key Lime Cheesecake
Craving a creamier take on the classic? Try a key lime cheesecake! Simply blend the filling ingredients from the pie with 16 oz of cream cheese until smooth. Pour the mixture over a graham cracker crust and bake at 325°F for about 45 minutes. Let it cool and chill before topping with whipped cream. This velvety version offers the zing of key lime with the lusciousness of cheesecake, making it the perfect dessert for any celebration.

Cooking Tips and Notes for Key Lime Pie
Ensuring a Perfect Crust
To achieve an ideal graham cracker crust for your key lime pie, make sure to press the crumbs firmly into the pie pan. This helps create a sturdy base that won’t crumble when slicing. A tip is to use the bottom of a glass or measuring cup to get an even finish. Bake until just golden—overbaking can lead to a hard crust.
Tips for Zesting Limes
Zesting limes adds intense flavor to your filling. For easy zesting, use a microplane or the fine side of a box grater. Be sure to only zest the green outer layer; the white pith underneath is bitter. Want more zesting tips? Check out this guide on how to zest citrus for more tricks!
