- 1/2 cup key lime juice (fresh or bottled)
- 1 tbsp key lime zest (optional, for extra zing)
For the Topping (Optional):
- 1 cup heavy whipping cream
- 2 tbsp powdered sugar
- 1/2 tsp vanilla extract
- 9-inch pie dish
- Mixing bowls
- Whisk or electric mixer
- Measuring cups and spoons
- Citrus zester (optional)
- Spatula
- Oven
- Refrigerator
1. Make the Crust
Preheat your oven to 350°F (175°C). In a bowl, combine graham cracker crumbs, sugar, and melted butter until the mixture resembles damp sand. Press the mixture evenly into the bottom and sides of a 9-inch pie dish. Bake for 8–10 minutes until lightly golden, then allow it to cool slightly while preparing the filling.
2. Prepare the Filling
In a medium bowl, whisk together sweetened condensed milk, egg yolks, key lime juice, and zest until smooth and well combined. Pour the filling into the cooled crust, spreading it evenly.
3. Bake the Pie
Bake for 15 minutes, or until the filling is just set but still slightly jiggly in the center. Remove from the oven and let it cool to room temperature, then refrigerate for at least 3 hours (or overnight) until fully chilled.
4. Make the Whipped Cream (Optional)
Using an electric mixer, beat heavy cream, powdered sugar, and vanilla extract until soft peaks form. Spread or pipe the whipped cream over the chilled pie just before serving.
- Use Fresh Key Limes if possible, as they provide the best flavor. If fresh key limes aren’t available, bottled key lime juice works as a great substitute.
- Let the Pie Chill Completely for the best texture. Overnight chilling enhances the flavor and consistency.
- For a More Intense Lime Flavor, add extra zest to the filling or garnish the finished pie with lime zest.
- Don’t Overbake! The filling should be just set and slightly wobbly when removed from the oven. It will firm up as it chills.
- Make it a No-Bake Pie: Skip baking the crust and let it set in the fridge for at least an hour before adding the filling.
- Swap the Crust: Try a vanilla wafer or coconut cookie crust for a unique twist.
- Dairy-Free Option: Use sweetened condensed coconut milk instead of regular condensed milk.
- Meringue Topping: Instead of whipped cream, top the pie with a toasted meringue for a classic variation.
- Refrigerator: Store the pie covered in the fridge for up to 4 days.
- Freezer: Wrap the pie tightly in plastic wrap and freeze for up to 3 months. Thaw in the refrigerator before serving.
- Drinks: Pair with a refreshing iced tea, margarita, or a glass of dessert wine like Riesling.
- Food Pairings: Serve after a seafood dinner, grilled chicken, or a tropical-inspired meal for a perfect balance.
Can I use regular limes instead of key limes?
Yes! While key limes have a unique tartness, regular Persian limes work well as a substitute.
How do I know when the pie is done baking?
The filling should be set but still have a slight wobble in the center when gently shaken.
Why is my pie runny?
This usually happens if it hasn’t been chilled long enough. Ensure it chills for at least 3 hours before slicing.
Can I make this pie ahead of time?
Yes! Key lime pie is actually best when made a day in advance, as it allows the flavors to meld.
