Spinach & Feta Breakfast Casserole
Spinach, potatoes, peppers, and onions mixed together with eggs form the base of this make-ahead feta breakfast casserole. A healthy breakfast casserole, perfect for any meal of the day and for meal prep.
This fully-loaded veggie and egg breakfast casserole is a delicious meal that comes together in just 10 minutes of prep time and 45 minutes of baking time. You can use any veggies that you have on hand for the casserole and I like to add some O’Brien potatoes with peppers and onions into the casserole, as that gives it density and also delicious flavor.
We haven’t left the house for a week with the coronavirus quarantine, but I had everything on hand to make this breakfast casserole in my refrigerator. Having a wide variety of veggies on hand allows you to prepare simple and healthy meals that fill your family’s bellies and help keep them satisfied without rummaging through the pantry every meal of the day. Be sure to read about top immunity boosting foods here.
This budget-friendly meal is a great way to clean out the refrigerator and serve up breakfast, lunch or dinner on the cheap. At a total cost of $8.56 to make this breakfast casserole with 8 servings, you’ll pay just $1.07 per serving.
If you wanted to sub shredded cheese for the feta, you could bring the cost down by a couple of dollars, but I had feta in the refrigerator, so I wanted to use up what I had on hand rather than head to the store.
