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

Ready to make this Key Lime Pie with Coconut Macaroon Crust? Follow these simple steps:
Step 1: Preheat Your Oven
Preheat your oven to 325°F (160°C). This ensures that your crust bakes evenly and becomes golden brown.
Step 2: Make the Coconut Macaroon Crust
In a mixing bowl, combine the sweetened coconut, egg white, vanilla extract, and salt. Mix until the coconut is fully coated and holds together when pressed.
Step 3: Form the Crust
Press the coconut mixture firmly into the bottom and up the sides of a 9-inch pie dish. Make sure it’s evenly distributed to create a sturdy crust.
Step 4: Bake the Crust
Place the crust in the preheated oven and bake for 10-12 minutes, or until it turns lightly golden. Keep an eye on it to prevent burning. Once baked, remove it from the oven and let it cool slightly.
Step 5: Prepare the Key Lime Filling
In a clean mixing bowl, whisk together the sweetened condensed milk, egg yolks, lime zest, and lime juice. Mix until smooth and well combined, ensuring there are no lumps.
Step 6: Fill the Crust
Pour the key lime filling into the cooled coconut macaroon crust. Use a spatula to spread it evenly.
Step 7: Bake the Pie
Return the pie to the oven and bake for an additional 15-20 minutes, or until the filling is set but still slightly jiggly in the center.
Step 8: Cool and Chill
Once baked, remove the pie from the oven and let it cool at room temperature for about an hour. Then, refrigerate for at least 3 hours or until fully chilled.
Step 9: Serve and Enjoy
Slice the pie into wedges and serve chilled. You can top it with whipped cream and additional lime zest for an extra touch of elegance and flavor!
Quick Replacement Ideas

If you’re missing an ingredient or looking to make substitutions, consider these options:

- Lime juice: If fresh limes aren’t available, bottled lime juice works in a pinch.

These substitutions can help you create a delicious pie, even if you’re low on certain ingredients.
