If you check out my recipe category  for Eggs, you see that I’ve come up with a lot of variations for low-carb breakfast casseroles through the years. I make breakfast casseroles on the weekend for Weekend Food Prep, cut into individual servings, and keep in a container in the fridge to eat for breakfast during the week.

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 Spinach and Mozzarella Egg Bake. This recipe is so simple that I’m not sure why it’s so popular, but it’s always one of the top ten recipes on this site if you check that list in the sidebar!

I did include this recipe in the recent collection of Low-Carb and Keto Breakfast Casseroles Your Family Will Love, but technically this is a variation I’m calling an egg bake. That means this Spinach and Mozzarella Egg Bake has lots of spinach and cheese, and just enough egg to barely hold it together. 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!

How to Make 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. Saute the spinach just until it’s barely wilted.
  2. Then spread it out in a layer in the bottom of the 8 1/2 X 12 casserole dish.
  3. Spread a generous layer of cheese over the spinach. No matter what else I’m using, I always add green onions!
  4. Pour the beaten eggs over the spinach and cheese.
  5. Then use a fork to “stir” the mixture so the spinach, egg, and cheese is well combined.
  6. Bake about 35 minutes, or until the mixture is set and lightly browned.
  7. 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

Yield 6 servings
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!


  • 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


  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.


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:
This Spinach and Mozzarella Egg Bake uses a generous amount of cheese, so it’s important to use low-fat mozzarella if you’re making it for the South Beach Diet. With that caution, everything here is a  low-glycemic ingredient and this recipe would be suitable for all phases of South Beach. This is also a great recipe for any other type of Low-Carb eating plan, and low-carb or keto diet plans would prefer full-fat cheese and wouldn’t even mind a bit more cheese!

  1. Made this morning.  Great!, loved it. 

  2. There is NO way that 5 oz of fresh spinach cooked and drained makes 4 packed cups! This reuires way more spinach. Other than that it is good.

    • The spinach from a 5 oz. package fills a 4 cup measuring cup for me, if I pack it down a bit. I guess it depends on your interpretation of the word “packed”. I think I’ll remove that word to avoid confusion. Either way, I made this with a 5 oz. package. Use more spinach if you prefer, of course!

  3. I made this split between an 8″x8″ square and a 9″ glass casserole round. Afraid I’d overcook it, I set the timer for 25 minutes, poked it, didn’t reset the timer, but took it out a few minutes later. It was thinner than I anticipated (I often pre-bake omelet ingredients in a muffin tin to make mornings easy in my house) but quite perfect. I don’t have Spike, but my husband and I use steak seasoning a lot, so I tossed that in without measuring it. It seemed like it was missing something and honestly I think my taste buds were looking for meat. If reheating the leftovers tomorrow is eventful, I’ll write again, but I suspect putting the pan back in the oven with a splash of water to keep the oven air humid will be just fine. I fully anticipate making this often, but likely with a small helping of browned sausage meat and/or diced ham cubes. Thanks for the inspiration!

    • If you enter “Breakfast Casseroles” into the search bar you will find many, many breakfast casserole options like this with meat. You might like one of those.

  4. Hi,
    I don’t have an 81/2×12 dish to bake it in. What size can I use, so it’s not too thin or too smal and uncooked. If I use a bigger baking dish, should I add spinach, eggs, or cheese.
    Thank you

    • I wish I knew what size dish you do have so I could tell you better how to adjust. But yes, if your dish is larger just add a bit more spinach, egg, and cheese. And if it’s smaller decrease each of them slightly. You will need to slightly adjust the cooking time, but probably not too much.

    • So glad you enjoyed it!

  5. Kids loved it. very good and easy recipe, i tried it last night

  6. Sorry, I just saw it is also listed as SBD phase 1 compliant. My error

  7. Why is the SBD phase 2…all the ingredients are SBD phase 1 compliant, if you use the part skim mozzarella.

  8. Made it this morning for bunch, turned out perfect! I did it with 11 eggs instead of 8 because I’m not watching carbs and the consistency was spot on!

  9. Great!
    Love your skills
    keep sharing things like this.

  10. I added onion, mushrooms, sausage, and Cheyenne pepper (and 4 extra eggs to compensate for the extra volume in the pan).

    So good!! I’ll definitely make this again.

  12. Use any seasoning that is good on eggs!

  13. What can you use if you don’t have Spike seasoning?

  14. any idea the nutritional info on this?? I loved it!!

    • Glad to hear you enjoyed it. More than a year ago I switched my site to WordPress, which created the need to edit by hand to add more than 2,000 recipes to the preferred format for google. I have been working on that (with three assistants) for more than a year, so there is no possibility of me being able to calculate nutritional information until that project is completed. And I know that once I start doing nutrition info on one recipe people will expect to see it on every recipe, which is why I have decided to keep these two projects completely separate.

      If you look after the recipe itself, I give two links (where it says “Nutritional Information”) for suggestions of two ways to get that information. That’s all I am able to do at this time.

    • BTW Kristy, Yummly is not always 100% accurate but the nutritional info for this recipe looks good to me.

  15. Which Spike Seasoning did you use? I see a couple different options when searching.

    • I agree that Spike has made it unnecessarily complicated by making their packages all look similar. The one I use is labeled “original Spike”. It is this one if you want to see the product on Amazon, also comes in jars.

    • It says in the recipe: 1 tsp. Spike seasoning (or use any all purpose seasoning mix that’s good with eggs).

  16. Can I make this a day ahead of time & then bake it the next day?

    • I haven’t done it that way but I think it might work. The only caution I’d give is that you probably need to let it come to room temperature after it’s been in the fridge overnight, otherwise the cooking time will definitely be off. But as I said, I haven’t done it so I don’t know for sure.

  18. This is so nice!!! I made and we had it at a picnic and everyone wanted seconds! I added a tiny amount of chilli flakes for a kick and now I have to share this page with everyone at the picnic!

  19. Looking forward to making this delicious recipe next week. Was trying to watch the video and didn’t see any place to click on it. Where is the video arrow? Thanks.

    • Hope you enjoy Joan! Videos should start automatically so if that didn’t happen something must have been wrong but it worked for me just now.

  20. This looks yummy. I will put it on the menu for next week. The only thing is, I like to freeze portions of food, so my husband can bring it to work and reheat it in the microwave. Now most egg recipes I tried to freeze, become very soggy after thawing. Any recommendations to avoid this?
    Thanks Brigitte.
