This zucchini egg bake is a high-protein, low-carb recipe that works equally well for breakfast, lunch, or dinner. Whip it up on a weekend and enjoy healthy meals all week long.

Whether you call it an egg bake, crustless quiche, or breakfast casserole, I love a good make-ahead egg breakfast. Not only are they made in one pan and super easy to prepare, but they are so versatile, and you can mix and match the veggies and ingredients based on the season.
This zucchini egg bake recipe is inspired by fresh and fragrant summer flavors. You can enjoy it as part of a weekend brunch, serve it with fresh fruit for a balanced breakfast, or with a green salad for a light lunch or dinner.

Why You’ll Love it

Ingredients + Substitutions
- Eggs – To add some protein. The recipe calls for whole eggs, but you can use a combination of eggs and egg whites if preferred. See the notes section of the recipe card for details.
- Zucchini – To add some veggies. The recipe calls for grated zucchini, or shredded zucchini, but sliced zucchini would also work well.
- Feta – To add some more protein and healthy fats. The recipe calls for feta cheese, but cottage cheese or shredded parmesan cheese would also work well.
- Milk – To add some more protein and ensure the eggs don’t come out rubbery.
- Fresh Herbs – To add some flavor. I used a mixture of parsley, basil, and dill, but any combination of fresh herbs will work well. You can use dried herbs if needed; see the notes section of the recipe card for details.
- Green Onion – To flavor the dish. The recipe calls for spring onions, but you can use a white onion or onion powder if needed. See the notes section of the recipe card for details.
- Garlic Powder – For additional flavor.
- Olive Oil – To add some healthy fats and grease the pan. You can use regular or extra virgin olive oil, avocado oil, melted butter, or cooking spray would also work well.
- Salt and Pepper – To season the zucchini and eggs.

Red’s Nutrition Tip
Eating a savory breakfast like this zucchini egg bake is a great way to eat less sugar. Not only do savory breakfasts contain little or no added sugar, but their high protein content, particularly when paired with high-fiber foods, can help to balance blood sugar and improve satiety throughout the day.
Serving Suggestions
This zucchini egg bake recipe is a high-protein, low-carb meal that is a good source of protein, fat, and micronutrients. It can be enjoyed on its own as a light breakfast or lunch, or served with additional items to create a more filling meal or suit your personal calorie or macro needs. For example:
- To make it higher in protein, add 1 cup of cottage cheese to the egg mixture.
- To make it lower in fat, swap half of the eggs for egg whites and/or use low-fat feta.
- To make it higher in fiber, serve it with a side of fresh berries.

Storage + Reheating
To Store: Once cooled, the zucchini egg bake can be stored whole, covered with aluminum foil or plastic wrap, or leftover pieces can be transferred to an airtight container and stored in the refrigerator for up to 3-4 days.
