You know, Key Lime Pie is one of those recipes that I feel like a lot of people are intimidated by, but I’ve made it SO easy for you here! In fact, you can get this one on the table with as few as 6 ingredients… seriously.
A more authentic Key Lime Pie calls for eggs, but I find that leaving them out and adding sour cream produces a smoother and creamier pie that we just love. In fact, I made both versions and served them to the family and everyone picked this version as the best. Just try it and you’ll see what I mean.
A quick note about the crust: If you’ve been around here any time at all, then you know I’m all about using shortcuts to make meal prep easy and less time consuming, so using a pre-made graham cracker pie crust is perfect here. Just try to get a deep dish one, if possible. Otherwise all the filling may not fit. If you want to make one from scratch (it’s super easy), you’ll find my recipe below.
Let’s also chat about Key Lime juice here. What makes this a KEY Lime Pie are the Key Limes. They’re not your standard Persian lime. The flavor is a bit different and they are much smaller. That means it will take a lot more to get the juice you’ll need for this pie. It took me about 20 Key Limes to get 3/4 cup juice. Now, you are welcome to use regular lime juice or even use bottled Key Lime juice, just know it will affect the flavor.
