An easy, delicious, and better-for-you spinach and mushroom feta casserole. Recipe includes a dairy-free option.
Defrost the spinach overnight in the fridge. Then place in a cheesecloth or thin towel and squeeze out all excess liquid. (Do not skip this step!)
Preheat oven to 375 degrees Fahrenheit.
Sauté onion in butter (or oil) until beginning to soften. Add mushrooms and continue to sauté.
Remove from pan and add spinach.
In a separate bowl, whisk together eggs, dressing, salt, and cheese if using. Pour wet ingredients over the veggies and mix to combine.
Place the mixture in an eight-inch square casserole dish and sprinkle the top with coating crumbs. Bake on 375 degrees for an hour.
For a dairy free option, sauté veggies in oil and omit feta cheese. Feta cheese is salty so you may want to add 1/2 teaspoon salt to compensate.
