Creamy and Delicious Key Lime Pie Recipe

This tart, sweet and simple to make super creamy key lime pie is perfect for summer afternoons. If you are a lime-lover, like I am, it is a welcome dessert year round! It pairs perfectly with a graham cracker crust, a dollop of whipped cream and, of course, a freshly brewed espresso.

What is a key lime? A key lime is a citrus hybrid fruit that is significantly smaller than its Persian cousins (a key lime is about the size of a ping pong ball). Regardless of their size, they pack a ton of flavor and are more acidic, aromatic and sweeter than other limes.

I suggest making the dessert a day in advance of serving it. This allows the filling time to set up properly and the flavor will be enhanced. Each component of this recipe only takes a few minutes to make so take the time to make the pie in advance and you will thank yourself!

Tips for Making the Perfect Key Lime Pie

Making the graham cracker crust:

  • Key lime pie is traditionally made with a graham cracker crust pressed into a pie tin. If you are looking to save a step you may certainly use a store bought crust..
  • This recipe calls for 2 cups of graham cracker crumbs. If making your own crumbs in a food processor you will need about 15 full graham crackers.
  • I like to save a bit of the graham cracker mixture to put on the edges of the pie prior to baking. It enhances the look and the extra crust is a great texture with the creaminess of the pie.

Ingredient tips for this creamy key lime pie:

  • Do you need to use key limes? No, but key limes are my preference. You will need approximately 12 – 15 key limes to achieve the 5 fluid ounces of juice needed in this recipe. Not everyone wants to spend time squeezing a dozen key limes. You will still get a spectacular pie using regular limes or my favorite lime juice from Nellie and Joe’s.

Mixing, baking and serving the pie:

  • The secret to the perfect key lime pie is in the mixing and baking of the pie. When combining the three ingredients for the filling (egg yolks, sweetened condensed milk, and lime juice), whisk the filling slowly and completely until the filling is homogenous.
  • If air bubbles form during the mixing, simply tap the bowl on the counter to allow the bubbles to escape.
  • This pie needs to bake slowly at a low temperature to allow the custard to set evenly. After baking for 16 – 18 minutes the middle of the pie will still be a bit ‘jiggly.’ This is what you are going for and you don’t want to overbake or you will have a a cheesecake texture.
  • Serving:
    • As tempting as it may be to serve the pie shortly after baking, don’t! Let the pie cool completely on a cooling rack then place it in the refrigerator for at least 2 hours (overnight is preferable). This will allow the flavors to meld and the filling to set properly.

FAQs

Can you freeze a key lime pie?

Yes! I have frozen quite a few key lime pies at the bakery with great success – there is no difference between my fresh baked pies and the ones which were frozen. To defrost, place the frozen pie in your fridge for 3 – 4 hours and allow to defrost completely before serving.

Can you use regular limes for a key lime pie?

Yes, but key limes are my preference as they pack a lot of flavor! If you don’t want to squeeze a ton of little key limes – purchase a key lime juice (my preference is Nellie and Joe’s).

Is key lime pie gluten-free?

The filling for this pie is gluten-free but the crust is not. Gluten-free graham crackers are available and may be substituted for the crust.
