Spinach and Eggs

This casserole is meatless vegetarian option, but when craving some extra protein with your breakfast be sure to give this cheesy sausage breakfast casserole or this overnight ham egg casserole a try.

Even without any meat, this casserole dish is packed with plenty of satisfying protein from the eggs and cheese. I used pre-packaged egg whites in this recipe, but only because the egg whites were on sale.

Some people believe that egg whites are better to consume than the whole egg. Egg whites do have less calories than a whole egg, but you are also missing out on some healthy vitamins and minerals.

For that reason I will include an option to use whole eggs in this recipe in the recipe card.

Spinach is also a nutritional powerhouse packed with Vitamin A, K and iron (Popeye approves!).

Bottom line…make this casserole today!

Spinach Egg Bake Frequently Asked Questions

Can frozen spinach be used in place of fresh spinach?

Yes, but I would defrost the spinach a day in advance and drain as much liquid as possible before adding it to the egg mixture.

How do you know when the egg casserole is done?

Place a knife in the center of the casserole and if it comes out clean, then it’s ready to be taken out of the oven. For a precise measurement use a thermometer. The temperature should reach 160 degrees.

Can spinach egg bake be made in advance?

Yes! To make this dish in advance, simple follow the directions and once ingredients are in the casserole dish cover and refrigerate. Note that to bake the next day, bring the dish to room temperature (approximately 30 minutes) or be prepared to bake for an extra 15 minutes.
