Sweet Potato Feta and Arugula Quiche

I made this quiche last week and had to make it again. It's that good. The crust is simple to make and chock-full of healthy fats from the flax and chia seeds. A piece of this for breakfast will keep your stomach happy and full till it's time for lunch. This recipe is gluten free and vegetarian.

Sweet Potato Feta and Arugula Quiche

Ingredients for the crust:

½ cup plus 1 tablespoon oat flour
¼ cup plus 1 tablespoon grated parmesan cheese
¼ cup ground flax seeds
2 tablespoons chia seeds
2 tablespoons olive oil
1 egg

Ingredients for the filling:

1 small white onion, chopped (about 1 cup)
1 medium sweet potato, diced (about 3 heaping cups)
2 cups packed arugula
5 eggs
⅓ cup feta cheese
1 tablespoon pesto, store-bought or homemade
1 tablespoon butter
1 tablespoon olive oil
1 teaspoon kosher salt
1 teaspoon Italian seasoning
¼ teaspoon red chili flakes

Generous grinds of pepper

To make:

Preheat oven to 350 degrees F. In a medium bowl, mix together oat flour, flax, chia seeds, and parmesan cheese. Create a little well in the flour mixture and add the egg and olive oil. Mix well and let sit for 5 minutes. Form dough into a round disk and place between two sheets of wax paper. Using a rolling pin, flatten out the dough. Carefully remove the sheets of wax paper and place dough into a greased 9-inch pie dish. Press dough into the dish and up the sides. Pierce dough several times with a fork and bake for 10 minutes. Remove from oven and set aside until your filling is ready.

In a large frying pan on medium-high heat, add butter and oil. Once it’s nice and hot, add onions and 1 teaspoon salt. Give it a quick stir and cook for about 1-2 minutes. Add the sweet potato and cook, stirring frequently for 5 minutes. Add Italian seasoning, pepper and red chili flakes. Cook for about 3 more minutes. Add arugula, gently stir and remove pan from heat.

Crack eggs into a bowl. Reserve one of the yolks. Add pesto to the bowl of eggs and whisk for about a minute. Using a pastry brush, spread the reserved egg yolk all over the inside of the crust. Layer half of the sauteed veggie mixture, half of the feta cheese and half of the pesto egg mixture. Follow the same steps with the remaining ingredients. Bake in the oven for 30 minutes.
