Step-by-Step: Key Lime Pie with Coconut Macaroon Crust

Step 1: Prepare the Coconut Macaroon Crust
Preheat your oven to 325°F (160°C). In a large mixing bowl, combine the sweetened coconut, egg white, vanilla, and salt. Mix well until the coconut is evenly coated.
Step 2: Form the Crust
Press the coconut mixture firmly into the bottom and up the sides of a 9-inch pie dish. Make sure it is compact and even. Bake for 10-12 minutes, or until the edges are golden brown. Remove from the oven and let it cool.
Step 3: Prepare the Key Lime Filling
In another mixing bowl, whisk together the sweetened condensed milk, egg yolks, lime zest, and lime juice until smooth and well combined.
Step 4: Pour the Filling
Once the crust has cooled, pour the key lime filling into the coconut macaroon crust, spreading it evenly.
Step 5: Bake the Pie
Bake the pie in the preheated oven for an additional 15-20 minutes, or until the filling is set but still slightly jiggly in the center.
Step 6: Cool and Serve
Let the pie cool at room temperature, then refrigerate for at least 2 hours before serving to allow it to fully set. Serve chilled, garnished with additional lime zest or whipped cream if desired.
Spring to Winter: Ideas
- Top with fresh berries in summer for a refreshing twist.
- Serve alongside a scoop of coconut ice cream for a tropical dessert.
- Use the same coconut macaroon crust for other flavors like chocolate or fruit fillings.
- For a festive touch in winter, add a sprinkle of cinnamon or nutmeg on top.
Troubles You Can Avoid
To ensure your Key Lime Pie with Coconut Macaroon Crust comes out perfectly, here are a few common pitfalls to avoid:
- Don’t overbake the filling; it should be set but still jiggle slightly when you take it out.
- Allow the crust to cool completely before adding the filling to prevent it from becoming soggy.
- Use fresh key limes for the best flavor, but if you can’t find them, bottled key lime juice will also work.
- Make sure to pack the coconut mixture firmly into the pie dish to prevent it from crumbling.
Make Ahead Like a Pro
This dessert is perfect for making ahead of time. You can prepare the coconut macaroon crust a day in advance and store it in the refrigerator. The filling can also be mixed and kept in the fridge until you’re ready to bake the pie. Just remember to bake and chill the pie at least a few hours before serving for the best texture and flavor.
Your Questions, Answered

While you can use unsweetened coconut, it will alter the flavor and sweetness of the crust. You may want to add a bit of sugar to compensate.
How do I store leftovers?

Can I freeze this pie?
Yes, you can freeze the pie. Wrap it tightly in plastic wrap and then in foil. It can be frozen for up to 2 months. Thaw in the refrigerator before serving.
