Spinach, Mushroom, and Feta Quiche

Spinach, mushroom, and feta quiche is loaded with fresh veggies and feta cheese. In fact, the flavor reminds me of Greek spanakopita. This quiche is super simple to make and wildly delicious. Start with a pre-made pie crust, sautee your veggies, whisk your eggs, and bake!

Quiche is easy to personalize you can almost always use your favorite veggies, cheese and even add in your favorite protein. It freezes well and is an easy reheat on the days you seem to not have enough time to make a meal. I love having it in the freezer for days when groceries are low and I want a home-cooked meal.

Can I bake it without a crust?

Absolutely! The same method as baking with a crust however generously spray your dish to avoid sticking. Cooking without a crust is a great low carb alternative.

How do I make Spinach, Mushroom and Feta Quiche?

    • Bake pie crust: Preheat the oven and bake crust for 10 minutes while you’re preparing the quiche.
