If you check out my ingredient category for Eggs, you’ll see a lot of low-carb and keto breakfast casseroles that are similar to this Spinach and Mozzarella Egg Bake. I make breakfast casseroles on the weekend for Weekend Food Prep, cut it into individual servings, and keep in a container in the fridge to eat for breakfast during the week.

But this simple breakfast casserole with spinach, eggs, green onion, and Mozzarella cheese has been wildly popular on the blog for years. I suspect it’s from people buying those big tubs of spinach at Costco and then googling “What can you make with spinach and eggs?” 

And low-Carb Breakfast Casseroles are definitely good any time of year, but when the weather gets cold you’re more likely to turn on your oven to make a breakfast like this, so I’m reminding you about this mega-popular breakfast idea! I love the idea of starting out the day with a big serving of spinach, and this Spinach and Mozzarella Egg Bake is so delicious you won’t even remember that you’re eating something that’s good for you! 

What ingredients do you need?

  • fresh spinach
  • olive oil
  • grated mozzarella cheese
  • green onions
  • eggs
  • Spike Seasoning (affiliate link), or use any all purpose seasoning mix that’s good with eggs
  • salt and fresh ground black pepper to taste

What is an egg bake?

This recipe is a type of breakfast casserole variation that I started calling an egg bake. That means the Spinach and Mozzarella Egg Bake has lots of spinach and cheese, and just enough egg to barely hold it together.

Is spinach and eggs a healthy combination?

No matter what kind of healthy eating plan you follow, spinach and eggs are healthy ingredients! Spinach (and other leafy greens) have more nutrients than almost any other food, and eggs are loaded with protein. You can also make this with liquid egg products or with more egg whites than yolks if that’s what works for you.

How to make the Spinach and Mozzarella Egg Bake:

(Scroll down for complete printable recipe with nutritional information.)

  1. I use a whole 5 oz. package of organic spinach in this, which is about 4 cups of baby spinach.
  2. Cook the spinach just until it’s barely wilted.
  3. Then spread it out in a layer in the bottom of the 8 1/2 inch x 12 inch casserole dish. Any size that’s close will work.
  4. Spread a generous layer of cheese over the spinach. No matter what else I’m using, I always add green onions!
  5. Pour the beaten eggs over the spinach and cheese.
  6. Then use a fork to “stir” the mixture so the spinach, egg, and cheese is well combined.
  7. Bake about 35 minutes, or until the mixture is set and lightly browned.
  8. Serve hot, or cut into portions to keep in the fridge and microwave for a minute or two for a quick healthful breakfast!

Spinach and Mozzarella Egg Bake

Prep Time 10 minutes
Cook Time 35 minutes
Total Time 45 minutes

This low-carb Spinach and Mozzarella Egg Bake has spinach, mozzarella, and green onion and just enough egg to hold it together!

Ingredients

  • 5 oz. organic fresh spinach (4 cups)
  • 1-2 tsp. olive oil (depending on your pan)
  • 1 1/2 cups grated mozzarella cheese
  • 1/3 cup thinly sliced green onions
  • 8 eggs, beaten
  • 1 tsp. Spike seasoning (or use any all purpose seasoning mix that's good with eggs)
  • salt and fresh ground black pepper to taste

Instructions

  1. Preheat oven to 375F/190C.  Spray an 8 1/2 inch by 12 inch glass or crockery casserole dish with olive oil or nonstick spray.
  2. Heat the oil in a large frying pan, add spinach all at once, and stir just until the spinach is wilted, about 2 minutes.
  3. Transfer spinach to the casserole dish, spreading it around so all the bottom of the dish is covered.
  4. Layer the grated cheese and sliced onions on top of the spinach.
  5. Beat the eggs with Spike Seasoning (affiliate link) (or other seasoning mix) and salt and fresh ground pepper to taste.
  6. Pour the egg mixture over the spinach/cheese combination, and then use a fork to gently "stir" so the eggs, spinach, and cheese are evenly combined.
  7. Bake about 35 minutes or until the mixture is completely set and starting to lightly brown.  Let cool about 5 minutes before cutting.
  8. The egg bake will settle down some as it cools.  Serve hot.
  9. This can be cut into individual servings to keep in the fridge and microwaved for a quick breakfast during the week.  Don't microwave longer than 1-2 minutes or the eggs can get slightly rubbery.

Notes

Definitely use more spinach if you prefer.

This is good with sour cream.  I also like a little Green Tabasco Sauce sprinkled on the top.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Spinach and Mozzarella Egg Bake This is a great recipe for any other type of low-carb eating plan, and low-carb or keto diet plans would use full-fat cheese for this and wouldn’t even mind a bit more cheese!

With that caution, this recipe would be suitable for all phases of South Beach.
