Tips and Tricks
- Use fresh key limes if possible; they provide a more vibrant flavor than bottled juice. If key limes are not available, Persian limes can be a suitable substitute.
- For an extra creamy filling, allow the sweetened condensed milk to come to room temperature before mixing.
- Don’t skip the chilling time! Letting your pie set in the refrigerator for at least three hours ensures the filling firms up properly.
- Garnish generously with whipped cream just before serving for an airy finish.
Common Mistakes to Avoid
- Avoid overbaking the pie; it should be set but still slightly jiggly in the center when you take it out of the oven.
- Don’t substitute regular lime juice for key lime juice, as the flavor will differ significantly.
- Be cautious with the sweetened condensed milk; using too much can make the pie overly sweet.
- Ensure you measure your key lime juice accurately to maintain the balance of flavors.
Make Ahead Tips
You can prepare the graham cracker crust a day in advance and store it covered at room temperature. The filling can also be made a day ahead; simply pour it into the crust and refrigerate. This pie stays fresh for up to 5 days in the refrigerator, making it a great option for meal preppers and busy cooks.
Recipe Variations
- For a tropical twist, add a layer of coconut cream on top of the whipped cream for a coconut key lime pie.
- Experiment with flavored whipped cream, such as adding a hint of vanilla or coconut extract.
- For a no-bake version, try using a pre-made graham cracker crust and let the filling set without baking.

How to Serve
Serve your key lime pie chilled, straight from the refrigerator. Garnish each slice with a dollop of freshly whipped cream and a sprinkle of lime zest for an added pop of color. For an extra touch, you can add a slice of key lime or a few fresh berries on the plate.
Pairing Suggestions
Pair your key lime pie with a refreshing glass of iced tea or a classic mojito to complement the citrusy flavors. If you prefer wine, a crisp Sauvignon Blanc works beautifully. For a more decadent experience, serve it alongside a scoop of vanilla ice cream.
How to Store
Store leftover key lime pie in an airtight container in the refrigerator for up to 5 days. If you want to freeze it, wrap individual slices in plastic wrap and then place them in a freezer-safe bag. The pie can be frozen for up to 2 months. Thaw in the refrigerator before serving.
