Key Lime Pie

Key lime pie is one of those timeless desserts that beautifully balances tangy citrus flavor with a sweet, creamy filling. This classic treat originates from the Florida Keys, where the small, aromatic key limes are abundant and highly prized for their distinct tartness. While traditional recipes might call for fresh key limes, this version works wonderfully with standard limes you can find at any grocery store, offering the same vibrant flavor in every bite.

The beauty of this dessert lies in its simplicity: a buttery graham cracker crust, a silky smooth lime filling made from egg yolks, sweetened condensed milk, and fresh lime juice, and a generous topping of whipped cream. The pie requires minimal baking and comes together with a handful of pantry staples, making it a perfect choice for both everyday indulgence and special gatherings. Whether you’re planning a summer party, need a refreshing finish to a heavier meal, or simply want a dessert that requires little fuss but delivers big on taste, this Key Lime Pie is an ideal go-to.

Once chilled and garnished with whipped cream and lime zest, it becomes a vibrant, crowd-pleasing dessert that’s guaranteed to disappear fast.

How to Make the Recipe

Step 1

Preheat the oven to 350°F (175°C). Prepare a 9-inch pie dish.

Step 2

In a bowl, combine graham cracker crumbs, sugar, and melted butter. Mix until evenly moistened.

Step 3

Press the crumb mixture into the bottom and up the sides of the pie dish to form the crust. Bake for 8–10 minutes until lightly golden. Let cool slightly.

Step 4

In another bowl, whisk together the egg yolks, sweetened condensed milk, and freshly squeezed lime juice until smooth and fully combined.

Step 5

Pour the lime filling into the prepared crust and bake for 15–17 minutes, just until the center is set but still slightly jiggly.

Step 6

Remove from oven and allow to cool at room temperature. Then refrigerate for at least 3 hours or until fully chilled.

Step 7

Top with whipped cream and lime zest before serving, if desired.

Tips for Making the Recipe

• Use fresh lime juice for the best flavor—bottled juice lacks the brightness needed.
• Let the pie cool completely before refrigerating to prevent condensation.
• Don’t overbake the filling; it should be set but still have a slight wobble.
• For a firmer crust, you can chill it before baking to help it hold together.
• Use room temperature ingredients for easier mixing and a smoother filling.

How to Serve

Serve chilled with a generous topping of whipped cream and optional lime zest for added fragrance and visual appeal. This pie pairs beautifully with light beverages like iced tea or sparkling water and makes a great end to any warm-weather meal.

Make Ahead and Storage

Storing Leftovers

Cover the pie tightly with plastic wrap or foil and store it in the refrigerator for up to 4 days.

Freezing

To freeze, wrap the pie (without whipped cream) securely in plastic wrap and foil. Freeze for up to 2 months. Thaw in the fridge overnight before serving.

Reheating

This pie is best served cold. Reheating is not recommended as it may affect the texture of the filling.

FAQs

1. Can I use bottled lime juice instead of fresh?

Yes, but fresh lime juice is strongly preferred for optimal flavor and brightness.

2. What’s the difference between key limes and regular limes?

Key limes are smaller and more aromatic, with a slightly more tart and floral taste than regular limes.

3. Can I make this pie crustless?

You can, but the crust provides essential texture contrast. Without it, the pie may be too soft.

4. Is this pie supposed to be baked?

Yes, baking sets the filling, even though it requires just a short time in the oven.

5. Can I make this ahead of time?

Absolutely! It’s best when chilled, making it a perfect make-ahead dessert.

6. Can I use a store-bought crust?

Yes, store-bought graham cracker crusts work well if you need a quicker option.

7. What’s the best way to zest the lime?

Use a fine microplane grater and zest only the green part, avoiding the bitter white pith.

8. Can I make it dairy-free?

You can try using coconut milk-based condensed milk and coconut cream for the topping.

9. How do I know when the pie is done baking?

It should be set around the edges but still slightly jiggly in the center.

10. Can I use egg substitutes?

Yes, but the texture and flavor might change slightly. Look for egg replacers made for baking.

Key lime pie is a dessert that delivers elegance with ease. Its tangy, creamy filling combined with a crunchy graham cracker crust creates a flavor experience that’s refreshing yet indulgent.
