Ingredients (Exact Measurements)
To make this classic Key Lime Pie, you will need the following ingredients:
For the crust:
* 1 1/2 cups (150g) graham cracker crumbs
* 1/3 cup (75g) unsalted butter, melted
* 1/4 cup (50g) granulated sugar
For the filling:
* 1 can (14 oz / 400g) sweetened condensed milk
* 1/2 cup (120ml) fresh key lime juice (or regular lime juice)
* 1 tablespoon lime zest
* 3 large egg yolks
For topping (optional):
* 1 cup (240ml) heavy whipping cream
* 2 tablespoons powdered sugar
* Extra lime zest or lime slices for garnish
Step-by-Step Instructions
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a mixing bowl, combine the graham cracker crumbs, melted butter, and sugar. Mix until the texture resembles wet sand.
Press the mixture firmly into the bottom and sides of a 9-inch pie dish, creating an even layer. Bake the crust for 8 to 10 minutes until lightly golden. Remove from the oven and allow it to cool slightly.
Step 2: Make the Filling
In a large bowl, whisk together the egg yolks until smooth. Add the sweetened condensed milk and continue whisking until fully combined.
Slowly add the lime juice while stirring. You will notice the mixture begin to thicken slightly. Add the lime zest and mix until everything is smooth and creamy.
Step 3: Fill and Bake
Pour the filling into the prepared crust and spread it evenly. Bake for 12 to 15 minutes, just until the center is set but still slightly soft.
Remove the pie from the oven and let it cool at room temperature. Once cooled, refrigerate for at least 3 hours, or preferably overnight, to allow the filling to fully set.
Step 4: Prepare the Topping
In a chilled bowl, whip the heavy cream with powdered sugar until soft peaks form. Spread or pipe the whipped cream over the chilled pie.
Garnish with lime zest or thin slices of lime for a fresh and decorative finish.
Serving Suggestions
Serve Key Lime Pie cold for the best flavor and texture. It pairs wonderfully with a cup of coffee, iced tea, or a refreshing fruit drink. This dessert is ideal for summer gatherings, barbecues, or holiday celebrations.
For an extra indulgent experience, serve each slice with additional whipped cream or a scoop of vanilla ice cream.
Tips for Perfect Key Lime Pie
Always use fresh lime juice for the best flavor. Bottled juice can work, but it may not provide the same bright and natural taste.
Do not overbake the filling. The pie should still have a slight jiggle in the center when removed from the oven, as it will firm up while chilling.
Chilling the pie thoroughly is essential for clean slices and the perfect creamy texture.
Variations
For a no-bake version, skip the eggs and use additional lime juice with whipped topping to set the filling. This creates a lighter, mousse-like texture.
You can also experiment with different crusts, such as a vanilla wafer crust or a coconut-infused crust for a tropical twist.
If you prefer a stronger citrus flavor, add a mix of lime and lemon juice for a more complex taste.
Storage Instructions
Store the pie in the refrigerator, covered, for up to 4 days. For longer storage, you can freeze it for up to 2 months. Thaw in the refrigerator before serving.
Keep in mind that the texture of the whipped topping may change slightly after freezing, so it is best added fresh if possible.
