I’ve found one of the keys to eating a healthy and balanced diet is to eat a healthy (and filling!) breakfast. It’s not always easy, especially on school mornings. On school mornings, I spend most of my time saying:

“Let’s go!”
“Eat your breakfast!”
“Hustle hustle!”
“Shoes! Coat! Backpack!”

Since mornings tend to be on the hectic side, I’ve found it extremely helpful to prep healthy breakfasts on the weekends and keep them in the fridge. When all that is required is a simple reheating, it’s much easier to make that breakfast happen. (Be sure to check out my list of 23+ easy breakfast recipes for more ideas).

This breakfast bake is one of the recipes I depend on. I’ll admit, this one’s more for me than the kids although my husband loves it too. It’s loaded with protein and lots of healthy vegetables so we get a big nutritional boost to start our day.

About This Egg White Breakfast Bake

This recipe is easy to make. All you need to do is stir everything together and bake it. Your food processor will make quick work of shredding the sweet potato; if you don’t have one, it’s easy to shred the sweet potato with your box grater, too. If you use the liquid egg whites, you don’t even have to crack the eggs.
The egg white breakfast bake is super nutritious. It contains lots of protein, with egg whites and cheddar cheese. Egg whites are cholesterol free, fat-free, and low calorie. Sweet potato has many health benefits, and of course, spinach is a nutritional powerhouse, as is any leafy green.
It’s a good make-ahead breakfast. Because this egg casserole stores well and reheats quickly, it’s perfect for food preppers. Make a large casserole, cut it into squares, refrigerate, and you’ll have an easy healthy breakfast for the next three to four days.
The recipe is versatile. You can easily make this egg casserole with whole eggs instead of egg whites. Choose your favorite type of cheese. Instead of spinach, add baby kale or another tender green. Add finely diced bell peppers or onions. Throw in cooked sausage or bacon.

Storage & Reheating Tips

Refrigerate: Cool to room temperature; cut into serving size portions, and refrigerate for up to 4 days.
Freeze: Breakfast bake can be frozen for up to 3 months. Bake as directed, cool to room temperature, cut, and package each portion separately. Thaw overnight in the fridge before reheating.
Reheat: Unwrap and reheat individual portions on a microwave-safe plate in the microwave on 50% power until heated through.
