Hello Spoonful of Flavor readers! Haley here from If You Give a Blonde a Kitchen. I’m happy to share a new recipe with you today! Just in time for summer, this 6-ingredient classic key lime pie is a refreshing dessert to make for friends and family.
Anyone who has made key lime pie before knows that the key (no pun intended) to a good pie is fresh lime juice. Yes, it requires a little extra work, but it’s smooth sailing after those limes are squeezed.
Key lime v lime
Key limes contain more concentrated aromatic juices, which gives the pie more flavor. They are also more yellow and smaller than regular limes.
Because key limes are so tiny, this recipe calls for a lot of them. I used around 50 key limes to make 3/4 fresh squeezed juice. Use a citrus squeezer to make the process quick and easy.
How to make key lime pie
A classic key lime pie recipe includes homemade pie crust. To make a homemade crust, stir together graham cracker crumbs, sugar and melted butter in a large bowl. Press the mixture into a 9-inch pie plate and bake in the oven at 375 degrees F for 7 minutes. Cool the pie crust completely before filling.
To make the pie filling, add condensed milk, sour cream and lime juice and zest to another large bowl. Mix well and pour into the baked pie crust. Tap the pie plate gently on the counter to release any bubbles. Bake in the oven at 350 degrees for five to eight minutes, or until the filling is set and barely jiggly. Do not let the pie brown. Chill the pie in the refrigerator for at least 4 hours before serving. Garnish with lime and serve with whipped cream, if desired.
See the recipe below for full measurements and details.
Once the limes are juiced, the rest of the recipe is simple. The filling only requires a couple more ingredients including the primary ingredient – sweetened condensed milk. The condensed milk makes the key lime pie incredibly smooth and rich.
Homemade graham cracker pie crust is the best crust for key lime pie. The buttery sweetness and crunchy texture compliments the citrus filling perfectly. The smooth pie filling in a homemade pie crust creates the best key lime pie recipe.
