How to Prepare No-Bake Key Lime Pie

Preparing this No-Bake Key Lime Pie is a breeze, and I promise you’ll love how simple and satisfying it is! Let’s break it down step by step so you can get that pie chilling in no time.

Step 1: Make the Crust

Start by combining 1 ½ cups of graham cracker crumbs, ½ cup of melted unsalted butter, and ¼ cup of granulated sugar in a bowl. Mix them well until everything is combined and resembles wet sand. Then, take this mixture and press it firmly into the bottom and up the sides of a pie dish. You want it nice and compact, so don’t be shy about getting your hands in there! This crust will be the perfect crunchy base for your creamy filling.

Step 2: Prepare the Lime Filling

In another bowl, mix together 1 can (14 oz) of sweetened condensed milk, ½ cup of sour cream, ¾ cup of fresh lime juice, and 1 tablespoon of lime zest. Make sure to use fresh limes for that vibrant zing! Whisk everything together until it’s super smooth and creamy—this is where the magic happens! The flavors meld beautifully, creating that tangy, luscious filling we all love.

Step 3: Assemble and Chill

Once your filling is ready, pour it into the graham cracker crust, spreading it evenly. Now, here’s the crucial part: cover the pie with plastic wrap and refrigerate it for at least 4 hours. This chilling time is essential for the pie to set properly, giving you that perfect slice. I know it’s hard to wait, but trust me, the final result is worth it! Once that time’s up, you’ll be ready to top it with whipped cream and dig in!
