With a perfect crispy crust and a creamy yet thick key lime filling, this is truly the best key lime pie you will ever have. You will only need 3 ingredients for the filling and 4 for the crust.
0 Butter the bottom and side of a 10-inch Pyrex or other oven-proof glass pie: set aside.
1 To make the crust: In a large bowl, combine the graham cracker crumbs, melted butter, sugar. Using your hands, mix thoroughly until the ingredients come together. Press the graham cracker mixture over the bottom and up the sides of the pie plate.
2 Preheat the oven at 350°F.
3 Place the piecrust in the oven and bake until lightly browned on the edges and firm, 8 to 10 minutes. Remove to a wire rack and let cool while you make the filling. Please don't turn off the oven.
4 To make the filling: In the bowl of a standing mixer fitted with the whisk attachment, beat the sweetened condensed milk with the yolks, salt, and lime zest on medium speed until thick and pale, 2 to 3 minutes.
6 Add the lime juice and beat until blended.
5 Pour the filling into the pie shell and bake, until the custard is set and just wiggle a bit in the center, 25 to 30 minutes. Remove to a wire rack and let cool for 15 minutes. Refrigerate until well chilled.
