INSTRUCTIONS
- Preheat oven to 350 degrees Fahrenheit and lightly grease a 9-inch deep dish pie plate.
- Heat olive oil in a large skillet over medium high heat. Add in onion and mushroom and saute until softened, about 5 to 7 minutes. Add in garlic and cook 1 minute more. Turn off heat and stir in spinach, feta, and cheddar cheese. Spoon mixture into the prepared pie plate.
- In a mixing bowl, whisk together eggs, milk, salt, and pepper. Pour egg mixture over the spinach mixture in the prepared pie plate.
- Bake in the preheated oven for 40 to 45 minutes, until eggs are set. Let cool 10 minutes before slicing and serving.
NOTES
Want to add a crust? Use frozen, pre-made, or . Instead of spooning the pie filling into an empty pie plate, you’ll spoon it directly into the crust. No par-baking required!
