Prep Time, Cook Time, and Servings
Preparation Time: 20 minutes
Cooking Time: 45 minutes
Chilling Time: 4 hours
Total Time: 5 hours and 5 minutes
Servings: 8 slices
Ingredients
For the crust:
- 1 ½ cups graham cracker crumbs
- ⅓ cup granulated sugar
- ½ cup unsalted butter, melted
For the filling:
- 2 (8 oz) packages cream cheese, softened
- 1 cup granulated sugar
- ½ cup sour cream
- ½ cup key lime juice (freshly squeezed if possible)
- 2 large eggs
- 1 tablespoon key lime zest
- 1 teaspoon vanilla extract
For the topping:
- Whipped cream (optional)
- Lime slices or zest for garnish (optional)
Instructions
Preheat the Oven: Start by preheating your oven to 325°F (160°C). This ensures your cheesecake bakes evenly and achieves that perfect creamy texture.
Prepare the Crust: In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Mix well until the crumbs are evenly coated with butter. Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish to form the crust. Bake in the preheated oven for 8-10 minutes until lightly golden. Remove from the oven and allow to cool slightly.
Make the Filling: In a large mixing bowl, use an electric mixer to beat the softened cream cheese until smooth and creamy. Gradually add the sugar and continue mixing until well combined.
Add Remaining Ingredients: Add the sour cream, key lime juice, key lime zest, and vanilla extract to the cream cheese mixture. Mix until smooth and well combined. Then, add the eggs one at a time, mixing just until incorporated after each addition. Avoid overmixing to ensure the pie remains light and creamy.
Pour Filling into Crust: Pour the creamy filling into the cooled graham cracker crust, spreading it evenly with a spatula.
Bake the Pie: Place the pie in the oven and bake for 40-45 minutes, or until the edges are set but the center still has a slight jiggle. This slight movement is essential for a creamy texture.
Cool the Pie: Once baked, remove the pie from the oven and let it cool at room temperature for about an hour. Afterward, transfer it to the refrigerator to chill for at least 4 hours, preferably overnight. This chilling time allows the flavors to meld beautifully.
Serve and Enjoy: Before serving, garnish individual slices with a dollop of whipped cream and a slice of lime or a sprinkle of lime zest if desired. Each bite will deliver a burst of citrusy flavor balanced by the richness of the cheesecake.
Pro Tips for Perfect Results
Use Fresh Key Limes: If possible, opt for fresh key limes rather than bottled key lime juice as it provides a more vibrant flavor.
Room Temperature Ingredients: Ensure your cream cheese and eggs are at room temperature for a smoother filling. This prevents clumps and helps achieve the desired creamy consistency.
Don’t Overbake: Keep an eye on your pie towards the end of the baking time. Overbaking can lead to a dry texture, so look for the slight jiggle in the center.
Chill Thoroughly: Allow the pie to chill for at least 4 hours or overnight. This enhances the flavors and texture, making it easier to slice.
Variations: Experiment with different citrus fruits like lemon or orange for a unique twist on flavor.
Variations and Substitutions
- Gluten-Free Option: Substitute the graham cracker crumbs with gluten-free options, such as almond flour or gluten-free crushed cookies.
- Dairy-Free: Use dairy-free cream cheese and coconut milk in place of sour cream for a delicious dairy-free version.
- Lower Sugar: For a lighter option, use a sugar substitute like monk fruit sweetener or stevia in reduced quantities, adjusting to taste.
Storage and Reheating Tips
To keep your Key Lime Cheesecake Pie fresh, cover it tightly with plastic wrap or aluminum foil and store it in the refrigerator for up to 5 days. It can also be frozen for up to 1 month. To thaw frozen pie, transfer it to the refrigerator for several hours or overnight. Reheat individual slices in the microwave for about 10-15 seconds if preferred slightly warmed.
