If you love creamy, tangy desserts, this casserole-style key lime pie is a fun twist on the classic Key lime pie. Inspired by the famous recipe from Sally’s Baking Addiction, this version is baked in a casserole dish, perfect for serving a crowd with less effort and more comfort-food vibes.
🌿 About This Recipe
This dessert combines a buttery graham crust with a smooth citrus custard filling made from sweetened condensed milk, egg yolks, and key lime juice. The acidity of lime naturally thickens the filling, while baking helps set it into a silky texture.
Unlike a traditional pie, the casserole format makes it easier to slice, serve, and store—ideal for family gatherings and parties.

👩🍳 Step-by-Step Instructions
Step 1: Prepare the Crust
Preheat your oven to 180°C (350°F). Mix graham cracker crumbs, macadamia nuts, sugar, and melted butter until the mixture becomes sandy. Press it evenly into a greased casserole dish, covering the bottom firmly.
Step 2: Pre-Bake the Base
Bake the crust for 8–10 minutes. This helps it hold shape and prevents sogginess when the filling is added.
Step 3: Make the Filling
In a bowl, whisk together sweetened condensed milk, egg yolks, lime juice, and zest until thick and creamy. The lime juice reacts with the milk to naturally thicken the mixture.
Step 4: Assemble
Pour the filling over the warm crust and spread evenly across the casserole dish.
Step 5: Bake
Bake for 15–20 minutes, until the center is slightly jiggly but mostly set. Avoid overbaking to maintain a smooth texture.
Step 6: Cool & Chill
Let it cool completely at room temperature, then refrigerate for at least 2–3 hours. This step is essential for the custard to firm up.
Step 7: Garnish & Serve
Top with whipped cream and lime slices before serving. Cut into squares and enjoy chilled.
