Key lime pie is famous the world over and for good reason. The simple custard pie is the perfect mixture of tangy, sweet, creamy, and crunchy. It also happens to be very easy to make at home.

Key limes are a variety of lime that is small, tart, and aromatic. They can sometimes be found in the grocery store, especially when in season and in citrus regions like Florida and California. While you can technically make this pie with regular limes, it will lack that special flavor that Key limes provide. Use freshly squeezed juice if at all possible, but bottled Key lime juice is an acceptable backup. Look for it in the juice aisle next to the bottled lemon juice.

You'll just need a few ingredients to make this recipe. Egg yolks give the pie richness and allow it to set up in the oven. Sweetened condensed milk makes it nice and creamy and sweet, an ideal counterpoint to the tart Key lime juice. A graham cracker crust provides sweet crunch—you can use a store-bought crust in a pinch to save time.

Topping the pie with a little whipped cream makes it extra special. Serve Key lime pie at your next barbecue, family gathering, or anytime you're craving a cool and creamy dessert. It's great for making ahead, too.


Steps to Make It

  1. Gather the ingredients. Preheat the oven to 350 F.

  6. Bake in preheated oven for 10 to 15 minutes to cook the eggs. The filling should have set up with a slight jiggle in the middle.

How to Store and Freeze

  • Cover and store the cooled pie for up to three days in the fridge. The crust will lose some of its crispness after the first day or two.
  • Make the whipped cream just before serving or make stabilized whipped cream for longer storage.
  • Key lime pie can also be frozen. Tightly wrap the cooled pie in plastic wrap and then aluminum foil and freeze for up to a month. Defrost in the fridge before serving.


  • If possible, use freshly squeezed Key lime juice. If using bottled juice, make sure to still use fresh zest. Regular lime zest can be substituted.
  • This pie can be made using regular limes. It won't have the same signature flavor that is expected from Key lime pie, but it will still be tasty.

Is Key Lime Pie Safe To Eat?

Some Key lime pie recipes are made using eggs but are not baked, prompting some to wonder if they are safe to eat. If you use fresh eggs and refrigerate the pie properly, you shouldn't have anything to worry about. However, if you are concerned or pregnant, try using pasteurized eggs or make a baked Key lime pie recipe instead.

Do You Serve Key Lime Pie Cold?

Key lime pie is commonly served cold since the pie sets up further as it chills. It can be made ahead of time and served directly from the fridge.
