This simple Spinach and Mozzarella Egg Bake that uses 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 even though it’s been ultra-popular, for years I’ve wanted to improve the photos for this recipe. When we finally did decide to take new photos, I discovered I no longer had the size of baking dish I’d used in the recipe, so we upgraded this to a recipe that now makes eight servings. But if you prefer the original version that used a slightly smaller dish and makes six servings, you can still find that here.

We did make a real effort to match the old photos, since this recipe has so many fans! If you’re someone who’s been making this breakfast casserole with spinach and Mozzarella cheese regularly, what do you think? Do you still recognize it in these new-and-improved pictures?

We actually made this two weeks in a row to get new photos we thought captured the dish, and Kara and I devoured it each time, and I happily warmed up leftovers for breakfast for a few days in a row. If you’re a spinach fan, or just like to start out the day with a healthy breakfast I hope you’ll give this a try!

What ingredients do you need?

  • fresh spinach
  • Olive Oil (affiliate link)
  • 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 a few years ago. What that title means is that 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.

What if you’re not a fan of Mozzarella cheese?

If you’re not a fan of the very mild flavor of Mozzarella cheese, you can definitely use another white cheese in this recipe such as white cheddar, Monterey Jack, or Swiss.

How to make the Spinach and Mozzarella Egg Bake:

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

  1. Preheat the oven to 375F/190C and spray a 9″ x 13″ casserole dish with non-stick spray.
  2. I used 12 oz. of organic spinach for the updated recipe. Heat the oil in a large frying pan and add the spinach all at once.
  3. Turn spinach over and over and cook the spinach just until it’s barely wilted, just a couple of minutes.
  4. Then spread out the wilted spinach out in a layer in the bottom of the casserole dish. 
  5. Spread a generous layer of cheese over the spinach and then add green onions!
  6. Season with the Spike Seasoning and some fresh-ground black pepper. (You can add salt if you like, but Spike has salt so we didn’t add more.)
  7. Pour the beaten eggs over the spinach and cheese.
  8. Then use a fork to “stir” the mixture so the spinach, egg, and cheese is well combined.
  9. Bake about 25-30 minutes, or until the mixture is set and lightly browned.
  10. Serve hot, or cut into portions to keep in the fridge and microwave for a minute or two for a quick and tasty breakfast!

Spinach and Mozzarella Egg Bake

Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes

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


  • 12 oz. organic fresh spinach
  • 2 tsp. olive oil
  • 2 cups grated mozzarella cheese
  • 1/2 cup thinly sliced green onions
  • 12 eggs, beaten
  • 2 tsp. Spike seasoning (or use any all purpose seasoning mix that's good with eggs)
  • fresh ground black pepper to taste


  1. Preheat oven to 375F/190C.  Spray a 9 inch X 13 inch 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. Season with Spike Seasoning (affiliate link) and fresh ground pepper to taste.
  6. Beat the eggs until they're well combined.
  7. Pour eggs over the spinach/cheese combination, and then use a fork to gently "stir" so the eggs, spinach, and cheese are evenly combined.
  8. Bake about 25-30 minutes or until the mixture is completely set and starting to lightly brown.  Let cool about 5 minutes before cutting.
  9. The egg bake will settle down some as it cools.  Serve hot.
  10. 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.


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 is a great recipe for any other low-carb eating plan including Keto, and low-carb or keto diet followers would use full-fat cheese for this and wouldn’t even mind a bit more cheese! However 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.
