Easy Gluten Free Key Lime Pie Recipe with Almond Crust

Key limes are the star of this recipe with their refreshing citrus flavor, but if you can’t find key limes then regular limes will work too as well as bottled lime juice. If you love key limes and would like your own regular supply, why not grow your own? You can read how in our article How to Grow Key Limes for Key Lime Pie.

I love that this recipe uses the whole egg, whereas many recipes use only the egg yolk. I always try to use whole eggs where possible to reduce food waste. Yes, you can make use of the egg whites in other dishes or even freeze them for later use but I prefer not to do this if I can help it. Because I know the egg white will end up forgotten and unused at the back of the freezer! Key Lime Pie can also be made with a meringue topping but I can’t go past whipped cream for an easy and delicious topping for this pie.

Key lime pie classically makes use of sweetened condensed milk, bringing sweetness to the recipe and so does this recipe.

While the sweet and sour flavors of the filling are balanced with the biscuity goodness of the almond crust.

Gluten Free Crust

Easy Gluten Free Key Lime Pie Recipe with Almond Crust

One way to make this recipe gluten free is by using gluten free graham crackers but this recipe is all about an almond crust. So almond meal makes up the basis of this delicious gluten free pie crust. Almond meal gives a lovely texture to the crust, so don’t get confused with almond flour. The main difference is that almond meal uses the whole almond, skin and all, while almond flour is usually made up of almonds without the skin and ground to a fine flour texture.

Helping to bind all the ingredients is the egg, butter, and xanthan gum.

If you’re already familiar with gluten free baking, you will probably know what xanthan gum is. But for those who are new to gluten free baking and unfamiliar with xanthan gum, it’s used in cooking to help bind and thicken foods. And it is particularly useful for gluten free cooking. If you check out the ingredients of gluten free flour, xanthan gum will usually be listed.

Don’t have xanthan gum? That’s ok. This recipe will still work and be delicious though the crust may be a little more crumbly.

Because this pie needs to set for at least 2 hours in the refrigerator, you can make it the day before and leave it to set overnight. So if you’re entertaining, this is an excellent dessert to make ahead.
