Ingredients You’ll Need
These ingredients are straightforward and work harmoniously to create the magic of this pie. Each item is essential—from the buttery crust to the velvety filling—offering just the right mix of flavor, texture, and freshness.
- 1 ½ cups graham cracker crumbs: Provides the crunchy, golden base packed with sweet and slightly nutty flavor.
- 1/3 cup granulated sugar: Adds sweetness to balance the lime’s tartness and helps bind the crust.
- 6 tablespoons melted butter: Binds the crumbs into a cohesive crust while enriching it with a buttery aroma.
- 2 (14-ounce) cans sweetened condensed milk: The silky sweetness that forms the luscious filling’s foundation.
- ¾ cup key lime juice: The star ingredient delivering that unmistakable tangy zest straight from the tropics.
- ½ cup sour cream: Adds a creamy texture and subtle tang that balances the filling perfectly.
- 1 tablespoon grated lime zest: Boosts the citrus flavor with a fragrant punch and a pop of color.
How to Make Easy Key Lime Pie Recipe
Step 1: Prepare and Prebake the Crust
Start by preheating your oven to 350°F. In a large bowl, mix the graham cracker crumbs, sugar, and melted butter until well combined. Press this mixture firmly and evenly into the bottom and up the sides of a 9-inch pie dish. This ensures a sturdy, crunchy crust that will hold the creamy filling perfectly. Pop the crust into the oven and prebake for about 8 minutes—this step prevents sogginess and deepens the buttery flavor.
Step 2: Whisk Together the Filling
While the crust cools slightly, whisk together the sweetened condensed milk, key lime juice, sour cream, and lime zest in a large bowl until smooth and silky. This mixture is where the magic happens—its creamy texture combined with zesty lime is what makes this pie so refreshing and addictive.
Step 3: Assemble and Bake
Pour the luscious filling into your prebaked crust, smoothing out the top with a spatula for an even finish. Bake the pie at 350°F for 18 to 20 minutes. At this point, the filling should be mostly set but still have a slight jiggle in the center—that’s perfect because it continues to set beautifully after baking.
Step 4: Chill and Let Rest
Allow the pie to cool at room temperature for about 30 minutes. Then, cover it and refrigerate for at least an hour to let everything firm up properly. Chilling not only helps set the pie but also lets those amazing lime flavors meld together for the tastiest experience.
How to Serve Easy Key Lime Pie Recipe
Garnishes
Simple garnishes can amplify this pie’s appeal without complicating the process. Freshly whipped cream dolloped on top complements the tangy filling wonderfully, while a sprinkle of lime zest adds a burst of freshness and an inviting aroma. Thin lime slices or even some crushed graham crackers on top can provide texture and visual delight.
Side Dishes
This pie pairs amazingly with light accompaniments. Consider serving it alongside fresh berries like raspberries or strawberries, which add natural sweetness and a pop of color. A cup of freshly brewed coffee or a chilled glass of sparkling water with lime can also enhance the citrusy goodness of the pie by balancing out its richness.
Creative Ways to Present
If you want to wow your guests with presentation, serve the pie in individual mini tart shells or jars for personal servings. Layering a bit of graham cracker crumbs at the bottom, then pie filling, topped with whipped cream makes a stunning parfait-style dessert. You can also drizzle a raspberry coulis or a light honey glaze over the top for added flair.
Make Ahead and Storage
Storing Leftovers
Leftover Easy Key Lime Pie should be kept refrigerated, tightly covered with plastic wrap or stored in an airtight container. It holds up well for up to three days, maintaining its delightful texture and fresh tang. Just make sure to keep it chilled to preserve its creamy consistency.
Freezing
Freezing is possible if you want to prepare the pie in advance. Wrap it securely in plastic wrap and then in aluminum foil to protect against freezer burn. It’s best consumed within one month. When ready to enjoy, thaw overnight in the refrigerator for the best taste and texture.
Reheating
This pie is best enjoyed cold, but if you prefer a slightly softer texture after refrigeration, leave it out at room temperature for about 15 minutes before serving. Avoid microwaving, as this can affect the creamy filling’s smooth texture and cause the crust to become soggy.
FAQs
Can I use regular lime juice instead of key lime juice?
Absolutely! While key lime juice has a unique tartness and floral notes, regular lime juice will still deliver that citrusy kick, making this an adaptable recipe anyone can enjoy.
Is it necessary to prebake the crust?
Yes, prebaking helps the crust firm up and prevents it from becoming soggy once you add the filling. It also enhances the buttery flavor and crunchiness of the crust.
Can I make this pie without an oven?
This recipe relies on baking to set the filling properly. However, no-bake variations exist but may not have the same texture. To get that signature silky finish, baking is best.
How long should the pie chill before serving?
For the optimal texture and flavor, chill the pie for at least one hour. If you can wait longer, refrigerating for several hours or overnight allows the flavors to deepen beautifully.
Can I substitute sour cream with something else?
You can use Greek yogurt as a substitute for sour cream. It will still give that creamy, tangy touch but with a slightly different texture and reduced fat.
