Ingredients You’ll Need
This Key Lime Pie keeps things wonderfully simple, and that’s part of its magic. Every ingredient plays an important role in building that creamy, citrus-packed filling that makes this one of my favorite easy dessert recipes to share year after year.

- 5 large egg yolks, beaten: Egg yolks help the filling set properly while giving the pie its rich, smooth texture. Using large eggs keeps the consistency balanced so the filling bakes evenly.
- 1 (14 ounce) can sweetened condensed milk: Sweetened condensed milk brings sweetness and creaminess all in one ingredient. Its thick texture helps create that signature silky filling without needing extra sugar or cream.
- ½ cup key lime juice: Key lime juice gives the pie its bold tart flavor and bright citrus finish. The amount matters here because it balances the sweetness of the condensed milk perfectly.
- 1 (9-inch) prepared graham cracker crust: The graham cracker crust adds a buttery, slightly crisp base that pairs beautifully with the creamy filling. A prepared crust keeps this recipe extra simple and convenient.
How to Make Key Lime Pie
I’ve always loved a dessert that looks impressive without making a mess of the whole kitchen, and this Key Lime Pie surely fits the bill. The filling comes together in just minutes, and once that pie hits the oven, your kitchen starts feeling like a sunny Southern bakery in the best possible way.

- Gather all of your ingredients before getting started so everything is ready to go when it’s time to mix the filling together.
- Preheat the oven to 375 degrees F (190 degrees C) so it’s fully heated before the pie goes in to bake.
- Combine the sweetened condensed milk, key lime juice, and beaten egg yolks in a large bowl. Mix well until the filling is fully blended and smooth.
- Pour the filling into the prepared graham cracker crust, spreading it evenly so the pie bakes consistently from edge to center.
- Bake the pie in the preheated oven until the filling is set, about 15 minutes.
- Cool the pie completely before slicing and serving so the filling has time to firm up properly.
Tips for the Best Key Lime Pie
- Mix Thoroughly — Make sure the egg yolks, condensed milk, and key lime juice are fully combined so the filling bakes evenly throughout the pie.
- Use the Full Cooling Time — Allowing the pie to cool completely helps the filling set cleanly, making every slice easier to serve.
- Pour Carefully — Slowly pouring the filling into the crust helps keep the graham cracker crust intact and evenly filled.
- Bake Until Set — The filling should be set before removing the pie from the oven so it holds its shape after cooling.
- Keep the Crust Even — Using a standard 9-inch crust keeps the filling-to-crust ratio balanced in every bite of this easy dessert.
Storage & Make-Ahead Tips
Fridge: Store leftover Key Lime Pie covered in the refrigerator for up to 3–4 days. Keeping it chilled helps the filling stay firm and creamy.
Freezer: You can freeze the pie for up to 3 months. Wrap it well to help protect the texture of the filling and crust while frozen.
Make-Ahead: This pie is a wonderful make-ahead dessert because it needs time to cool completely before serving. Preparing it earlier in the day gives the filling plenty of time to set.

Frequently Asked Questions
Q: What makes Key Lime Pie different from other citrus pies?
Key Lime Pie has a signature sweet and tart flavor that comes from the combination of key lime juice and sweetened condensed milk. The filling is extra creamy and smooth compared to many other citrus pies, and the graham cracker crust adds a slightly crunchy contrast that makes every bite feel balanced and rich.
Q: Can I make this pie ahead of time?
Yes, this pie works beautifully as a make-ahead dessert. Since the filling needs to cool completely before slicing, making it earlier in the day can actually improve the texture. Once cooled, keep it covered in the refrigerator until you’re ready to serve.
Q: Why do the egg yolks matter in this recipe?
The egg yolks help give the filling its smooth texture while also helping it set during baking. Without them, the pie would not have the same creamy consistency or structure when sliced. Beating the yolks before mixing helps everything combine more evenly.
Q: How do I know when the pie is done baking?
The pie is ready when the filling is set after baking for about 15 minutes. Once it cools completely, the filling continues to firm up, giving you clean slices and that classic creamy texture Key Lime Pie is known for.
Q: Can I use a prepared graham cracker crust?
Absolutely. This recipe is designed to work with a prepared 9-inch graham cracker crust, which makes the process quicker and easier. It’s a great shortcut that still delivers plenty of flavor and texture in the finished pie.
Q: Is this a good dessert for warm-weather gatherings?
It surely is. The bright citrus flavor and cool creamy filling make this pie especially popular for summer meals, cookouts, and family get-togethers. It’s light enough to enjoy after a hearty dinner but still rich enough to feel special.
Q: Why does the pie need to cool completely before slicing?
Cooling gives the filling time to finish setting properly. If sliced too early, the filling may not hold its shape as well. Letting the pie cool completely helps create cleaner slices and a firmer texture.
There’s just something downright joyful about pulling a homemade Key Lime Pie out for family and friends. It’s creamy, bright, easy to make, and full of that old-fashioned charm that keeps folks coming back for another slice.
