Who needs a pastry crust, when you can have a delicious sweet potato crust?! This Spinach Quiche is made with a Sweet Potato Crust to deliver a gluten-free version of a spinach quiche that is both nutritious and delicious!
I love quiche! But there have been many times in my life when I have needed a gluten-free version for myself or my guests, which led me to create a quiche using a sweet potato crust.
Not only does swapping out the traditional pie crust for a sweet potato crust yield a gluten-free and grain-free quiche, but the sweet potato crust adds an element of delicious surprise!
Reasons to Love Sweet Potato Quiche
- Amazing Flavor. The sweet potatoes not only give this quiche substance, but they lend a sweet, earthy flavor as well. Paired with spinach and roasted red peppers, the flavors are perfection!
- Allergy-Friendly. By using a sweet potato crust, this recipe is already gluten-free and grain-free, but it can easily be made dairy-free as well.
- Adaptable. If you aren't in the mood for a spinach and roasted pepper quiche, use this Sweet Potato Quiche Crust as a base for Ham and Cheese Quiche or Quiche Lorraine.
How to Make Quiche with Sweet Potato Crust
The following tips are provided to help you achieve perfect results. You will find the detailed instructions in the recipe card at the bottom of this post.
Step One: Prepare Sweet Potato Crust. A sweet potato crust is easy to prepare. Simply shred peeled sweet potatoes using a food processor and then press the shredded potatoes into a greased pie plate or springform pan. Use a glass or your hands to FIRMLY press the sweet potatoes into the pan.
Step Two: Bake Sweet Potato Crust. It is crucial to prebake the crust as this lets the sweet potatoes cook and begin to get crispy before adding the quiche filling.
Step Three: Make Quiche Filling. Whisk the eggs together with milk of choice, and seasonings, and then add in drained spinach, feta, and red peppers.
Step Four: Bake Sweet Potato Quiche. Remove the crust from the oven, pour the egg mixture into the crust, and return to the oven to allow the sweet potato crust to finish baking the eggs set up.
Step Five: Serve. It is best to let the quiche cool for 10 minutes before serving.
Storage
- Refrigerate: Leftover sweet potato quiche can be stored in an air-tight container for up to 3 days.
- Reheat: For best results, reheat in a dry skillet or a 400-degree oven for 3-4 minutes. This will prevent your crust from being soggy once reheated.

I'm really digging this quiche. I've made a similar crust out of dried coconut flakes. Using sweet potatoes as the crust is a nice change.

I NEVER would have thought to use coconut flakes--that is a great idea!

Quiche makes me weak in the knees. Sadly, I hardly ever make it because I always thought it was really hard to make. I love the idea of a sweet potato crust (I'm currently OBSESSED with sweet potatoes). Thanks for the recipe!

I can just see it being the star of my southern garden party, brunch or keeping it all to myself. That sweet potato crust looks so crispy and delicious. I'm pinning so I won't lose the recipe.
