Step-by-Step Directions
1. Prepare the Graham Cracker Crust
Start by preheating your oven to 350°F (175°C). In a mixing bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Mix until the crumbs are evenly coated and the mixture resembles wet sand. Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish. Bake the crust in the preheated oven for 10 minutes, or until it’s lightly golden. Remove from the oven and let it cool on a wire rack.
2. Make the Pie Filling
While the crust is cooling, prepare the pie filling. In a large mixing bowl, whisk the egg yolks until they are pale and slightly thickened. Gradually add the sweetened condensed milk, whisking until fully combined. Stir in the key lime juice and zest, and continue whisking until the mixture is smooth and creamy.
3. Assemble the Pie
Pour the pie filling into the cooled crust, using a spatula to spread it evenly. Bake the pie at 350°F (175°C) for 15-20 minutes, or until the filling is set but still slightly jiggly in the center. Remove the pie from the oven and let it cool to room temperature. Once cooled, refrigerate the pie for at least 3 hours, or until it’s fully chilled.
4. Prepare the Whipped Cream Topping
Just before serving, prepare the whipped cream topping. In a mixing bowl, combine the heavy whipping cream, powdered sugar, and vanilla extract. Use an electric mixer or whisk to beat the mixture until stiff peaks form. Spread or pipe the whipped cream over the chilled pie, and garnish with additional lime zest if desired.
Tips and Variations
Tips for the Perfect Key Lime Pie
- Use Fresh Key Limes: For the most authentic flavor, use fresh key limes. However, bottled key lime juice can be a convenient substitute if fresh limes are unavailable.
- Don’t Overbake: The pie should be slightly jiggly in the center when you remove it from the oven. It will continue to set as it cools.
- Chill Thoroughly: Make sure to refrigerate the pie for at least 3 hours before serving. This helps the flavors meld together and ensures a firm texture.
Recipe Variations
- Chocolate Key Lime Pie: Add a layer of melted chocolate on top of the graham cracker crust before adding the pie filling for a chocolate twist.
- Coconut Key Lime Pie: Mix shredded coconut into the graham cracker crust or sprinkle toasted coconut on top of the whipped cream for a tropical variation.
- No-Bake Key Lime Pie: Skip the oven altogether by using a no-bake crust made from crushed graham crackers and melted butter. Chill the crust before adding the filling and setting it in the refrigerator.
