Key Lime Pie

I’ve been making this Key lime pie for years, and it’s one of my favorite desserts to serve when the weather warms up. Inspired by the classic pie made famous in the Florida Keys, it has a buttery graham cracker crust and a cool, creamy filling that’s the perfect balance of sweet and tart. Best of all, it’s easy to make with just a handful of ingredients—you can use regular limes from the grocery store, and Greek yogurt stands in for the usual egg yolks (trust me, it works). I’ve served this pie everywhere from summer barbecues to holiday dinners, and it’s always a crowd-pleaser.

What You’ll Need To Make Key Lime Pie

For the crust, you’ll need finely crushed graham cracker crumbs, light brown sugar, and melted butter. For the filling, you’ll need sweetened condensed milk, Greek yogurt, fresh lime juice and lime zest. For the topping, you’ll need heavy cream and confectioners’ sugar.

You’ll notice this recipe doesn’t call for egg yolks, like many traditional Key lime pie recipes. After testing it both ways, I found they simply weren’t necessary. The pie sets beautifully because the lime juice’s acidity reacts with the proteins in the yogurt and sweetened condensed milk, thickening the filling as it bakes (the same basic reaction that turns milk into cheese). And from a taste standpoint, I actually prefer the cleaner, brighter lime flavor that comes from leaving the yolks out. As a bonus, there’s no separating eggs, making the recipe even easier to prepare.

Step 1: Mix the crust. Combine the graham cracker crumbs, brown sugar, and melted butter, stirring first with a fork, then finishing with your hands until the mixture looks like damp sand and holds together when you squeeze a bit in your palm.

Step 2: Press the crust into the pan. Work the crumbs up the sides of the pan first, then press the bottom—it’s easier this way. Press firmly; a loosely packed crust tends to crumble when you slice the pie later.

Step 3: Blind bake. Bake just until the edges turn a shade darker and it smells toasty. This short bake deepens the flavor of the crust and keeps the crust from turning soggy once the filling goes in, but it doesn’t need to brown deeply.

Step 5: Whisk the filling. Whisk the condensed milk, yogurt, zest, and juice together until completely smooth. The mixture will look thick, almost like a pudding.

Step 6: Bake and chill. Pour the filling into the warm crust and bake until the center looks just set. Let it cool for a bit on the counter, then pop it in the fridge for at least 3 hours to set completely. It’ll firm up further as it cools and chills.
