Step-by-Step
Instructions for Key Lime PieFollow these simple steps to make your own Key Lime Pie:
1. Make the Crust for Key Lime Pie
- Preheat the Oven: Preheat your oven to 350°F (175°C) to bake the crust.
- Prepare the Crust: In a medium-sized bowl, combine the graham cracker crumbs, sugar, and salt. If you’d like an added depth of flavor, mix in the cinnamon. Stir the dry ingredients until well combined.
- Add Butter: Pour the melted butter over the graham cracker mixture, stirring to ensure that the crumbs are fully coated. The texture should resemble wet sand.
- Press into Pan: Transfer the graham cracker mixture into a 9-inch pie dish. Press the mixture firmly into the bottom and up the sides of the pan to form a crust. You can use the back of a spoon or your fingers to help press it evenly.
- Bake the Crust: Place the pie crust in the preheated oven and bake for 8-10 minutes, or until the crust is golden brown. Keep an eye on it to prevent overbaking. Once done, remove it from the oven and let it cool completely while you prepare the filling.
2. Prepare the Filling for Key Lime Pie
- Combine Ingredients: In a large bowl, whisk together the sweetened condensed milk, key lime juice, egg yolks, vanilla extract, and a pinch of salt. Whisk until everything is well combined and smooth.
- Pour into Crust: Pour the filling into the cooled graham cracker crust, smoothing the top with a spatula to ensure it is evenly distributed.
- Bake the Pie: Bake the pie in the oven at 350°F (175°C) for 12-15 minutes. You’ll know the pie is done when the edges are set and slightly puffed, but the center still has a slight jiggle when you gently shake the pan.
- Cool the Pie: Allow the pie to cool at room temperature for 30 minutes. Once cooled, refrigerate the pie for at least 3-4 hours to allow it to fully set.
3. Serve the Key Lime Pie
- Top with Whipped Cream (Optional): Once the pie is fully chilled and set, top it with a generous dollop of whipped cream if desired. Garnish with lime slices or zest to make it look extra beautiful.
- Slice and Serve: Use a sharp knife to slice the pie into wedges. Serve each slice with a little extra whipped cream or a lime wedge on the side for a finishing touch.

How to Serve Key Lime Pie
Key Lime Pie can be served in a variety of ways, depending on your preference:
- With Whipped Cream: A generous scoop of freshly whipped cream on top adds a creamy, sweet contrast to the tangy filling.
- With Lime Slices: Garnish with lime slices or zest for a pop of color and added lime flavor.
- For a Crowd: Key Lime Pie is perfect for a summer gathering, picnic, or party. Serve slices on a platter, and your guests will be sure to love it.
- As a Refreshing Treat: It’s the perfect dessert after a heavy meal, especially on warm days when something cool and refreshing is just what you need.
Additional Tips for Key Lime Pie
To ensure that your Key Lime Pie turns out perfect every time, keep these tips in mind:
- Use Fresh Lime Juice: Fresh lime juice provides the best flavor. While bottled lime juice will work, the fresh juice has a brighter, more authentic flavor.
- Chill the Pie Long Enough: Be patient and let the pie set for the full 3-4 hours in the refrigerator. This allows the filling to firm up and ensures the pie holds its shape when sliced.
- Don’t Overbake the Filling: When baking the pie, keep a close eye on it. Overbaking can result in a tough texture, so bake just until the edges are set and the center is still slightly wobbly.
- Make It Ahead: Key Lime Pie is an excellent dessert to prepare the night before. It actually tastes better after sitting for a while, allowing the flavors to meld together.
Recipe Variations for Key Lime Pie
If you’re looking to switch up the traditional Key Lime Pie, here are some fun variations you can try:
- Coconut Key Lime Pie: Add a cup of shredded coconut to the crust for a tropical twist.
- Strawberry Key Lime Pie: Top your pie with fresh strawberries or swirl some strawberry puree into the filling for a fruity variation.
- Chocolate Key Lime Pie: Drizzle a thin layer of melted dark or milk chocolate over the graham cracker crust before adding the filling for a chocolate-lime fusion.
- Vegan Key Lime Pie: Replace the egg yolks with coconut cream and use a dairy-free condensed milk alternative for a vegan version of this dessert.
- Key Lime Cheesecake: Add cream cheese to the filling for a rich, cheesecake-style Key Lime Pie.
- Mango Key Lime Pie: Blend in some mango puree for a delicious tropical twist that pairs perfectly with the tart lime.
Freezing and Storage for Key Lime Pie
- Freezing: Key Lime Pie freezes beautifully. If you want to make it ahead of time, simply freeze it before adding the whipped cream topping. Wrap the pie tightly in plastic wrap and foil, and it will keep for up to 3 months. To serve, thaw it in the refrigerator overnight.
- Storage: Keep any leftover pie in the refrigerator for up to 3-4 days. Be sure to cover it tightly with plastic wrap or store it in an airtight container to maintain its freshness.
Special Equipment for Key Lime Pie

- 9-Inch Pie Dish: A standard 9-inch pie dish is the perfect size for this recipe. You can use a glass or ceramic dish for even baking.
- Whisk: A good whisk is essential for mixing the filling to ensure it’s smooth and well-combined.
- Pie Server: A pie server is helpful for cutting and serving slices neatly.
- Citrus Juicer: If you’re using fresh limes, a citrus juicer will help extract juice more efficiently.

- Plastic Wrap or Foil: Use these to wrap the pie tightly for storage or freezing.
