Ingredients

Tips & Substitutions
For a more intense lime flavor, consider adding a pinch of lime zest to the mixture. If you're short on time, a pre-made graham cracker crust works great as a substitute for making your own. For a lighter version, you can use Greek yogurt instead of sour cream. This pie pairs beautifully with Low Calorie Viennese Hot Cocoa Mix during the holidays for a refreshing dessert option.
Serving Suggestions
Serve the key lime pie chilled, topped with generous dollops of Cool Whip for added creaminess. Fresh lime slices or zest make for a beautiful garnish. This pie is a perfect standalone dessert but also pairs well with a side of fresh fruit or a scoop of vanilla ice cream for a delightful contrast.
Storage & Reheating
Store any leftover key lime pie in an airtight container in the refrigerator for up to 3 days. It’s best enjoyed cold, so no need to reheat; simply slice and serve straight from the fridge for a refreshing treat.

Frequently Asked Questions
Can I use regular lime juice instead of Key lime juice?
While you can use regular lime juice, the flavor will be different. Key limes provide a unique tartness that is essential for authentic key lime pie. If you must substitute, use a blend of lime and lemon juice to mimic the flavor profile.
How do I know when the pie is set?
The pie should be firm to the touch but slightly jiggle in the center when you gently shake it. Refrigerating it for at least 1 to 2 hours after pouring the filling helps it set properly.
Can I make this pie ahead of time?
Yes! Key lime pie can be made a day in advance. Just be sure to cover it well with plastic wrap or foil in the refrigerator to maintain its freshness. This allows the flavors to meld beautifully, making it even tastier when served.
