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!

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! The recipe uses a generous amount of cheese, so it’s important to use low-fat mozzarella if you’re making it for the original South Beach Diet. With that caution, this recipe would be suitable for all phases of South Beach.

  1. Turned out great, I added some red pepper, zucchini and asparagus, garlic and some savory spices from Penzeys.

  2. I was in a hurry so I made this on top of the stove in an 8 inch cast-iron skillet.  I reduced the amount of the ingredients, put a lid on it and cooked it on low until it was well set. The top was not brown but the bottom was. Delicious 

    • Fun, it sounds like you turned it into a Frittata. You could brown the top under the broiler. I need to try this idea!
