Key Lime Pie Ingredients

These are the five ingredients you'll need to make this top-rated Key lime pie recipe:

· Sweetened condensed milk: This sweet, smooth, and creamy Key lime pie starts with a can of sweetened condensed milk.
· Key lime juice: Key lime juice comes from the Florida Keys. Key limes are more acidic than regular limes, so they pack a flavorful punch.

· Lime zest: A tablespoon of lime zest enhances the bold citrusy flavor.
· Graham cracker crust: Use a store-bought or homemade graham cracker crust.

2. Bake the pie: Bake the pie in a preheated oven until tiny bubbles appear and pop on the surface of the pie.

How to Store Key Lime Pie

Cover the cooled Key lime pie tightly with storage wrap or foil. Store in the refrigerator for up to three days. Serve chilled.

Can You Freeze Key Lime Pie?

Yes! You can freeze Key lime pie for up to three months (but make sure you don't add whipped cream or toppings until after it's thawed). If you plan to freeze the pie, bake it in a foil pan. Wrap the cooled pie in at least one layer of storage wrap, then follow it up with at least one layer of foil. Thaw in the refrigerator overnight.

"I love this recipe, it's fabulous," says Stephanie White. "I also experimented and used lemon in place of the lime (just to find a use for my over abundance of lemons) and it turned out great."

"This Key lime pie is delicious," raves Debidoooo. "I make a homemade graham cracker crust and add one-third cup of toasted shredded coconut to the crust. Everyone raves about this pie. Try it… won't be disappointed."

"This recipe was excellent," raves one Allrecipes community member. "The only change I made was to substitute plain yogurt for the sour cream because I didn't have any. Everyone enjoyed it."
