Healthy Zucchini Egg Bake has been our go to summer breakfast.

When your garden is overflowing with zucchini and you simply can’t make another Healthy Zucchini Bread… this is what you should make!

High protein, meal prep friendly, quick to prep and cook – it’s the perfect breakfast.

Egg and zucchini pair deliciously with fresh herbs and lots of cheese for a yummy breakfast that even picky toddlers will enjoy (we can attest to this!)

Tyler’s Tips for the Best Egg Bake

  • Don’t skip sautéing the zucchini- Zucchini has a lot of water in it and sautéing it helps prevent soggy eggs!
  • Grease the pan well– Use lots of butter or oil so your eggs don’t stick!

substitutions

Olive Oil: You could use avocado oil, but we really recommend extra virgin olive oil.

Vegetables: Feel free to add more veggies. Peppers or mushrooms would be delicious.

Adding meat: You can add cooked bacon or breakfast sausage to this casserole. Check out these recipes for other ideas: Sausage Egg Bake, Bacon Breakfast Casserole, Egg Hashbrown Casserole.

What to Serve with Egg Bakes

Here are some of our favorite things to serve with this simple zucchini egg bake:

storage

Storing: This breakfast casserole can stay in the refrigerator for up to 3 days.

Can I make this egg bake ahead of time? Absolutely! You can make this breakfast casserole ahead of time and reheat it before serving.

Freezing: You can freeze this healthy egg casserole, but we don’t recommend it. We find that frozen/reheated eggs can be a bit soggy but if you don’t mind that, it will freeze! T

Reheating: We prefer to reheat this in the toaster oven/oven. 350-375° for 5-8 minutes should do the trick – but just watch your oven and check after 5 minutes. You can microwave this, but we don’t recommend microwaving eggs. I find it gives them a bouncy texture that we don’t care for.
