Our family holidays center around food, and “eating healthy” tends to go on the back burner. The last thing that will pass our food-loving family is food that tastes too healthy (and our opinionated bunch will not hesitate to let you know as much). At the same time, however, by the time we’ve hit our third or fourth day of non-stop decadence, a few members of my family (myself included) appreciate a healthy breakfast recipe to provide some nourishment and reprieve. That’s where this healthy breakfast casserole with potatoes and spinach comes in (or this Pesto Quiche). LOADED with vegetables and paired with classic hearty additions like hash brown potatoes and sausage, this is a healthy breakfast casserole that even the diner-style breakfast purists at your table will also approve of.

Like my other favorite healthy breakfast bakes (Whole30 Breakfast Casserole and Crockpot Egg Casserole), this recipe can be assembled the day before to make your morning easy-breezy.When you wake up, just preheat the oven, put on the coffee, and slip this easy breakfast casserole into the oven.

Without fail, the scent of melting cheese and zesty sausage will lure your family into the kitchen, as will any of my other breakfast casserole recipes!

The Best Easy Breakfast Casserole – A Shortcut

Since the holidays are busy enough as it is, I wanted to take any time-saving measures I could find to speed this recipe along. Frozen veggies are one of my go-time time savers, so I decided to see if I could make a healthy breakfast casserole with frozen hash browns, like the ones that I use for Hash Brown Casserole. TOTAL SUCCESS. Rather than dice the potatoes, I swapped in thawed frozen diced hash brown potatoes. They tasted absolutely perfect, to the extent that I may never make a breakfast casserole the old way again (I’ll save fresh potatoes for this Potato Frittata).

How to Make Healthy Breakfast Casserole

This healthy breakfast casserole with sausage is filling, flavorful, and offers big-time appeal for everyone at the table. In fact, don’t even mention the “h”-word. Your family will never suspect it!

The Ingredients

Eggs. The “glue” that holds all of our delicious casserole ingredients together. Packed with protein, choline, and numerous vitamins, eggs are an incredibly healthy ingredient. Italian Sausage. With added spices, Italian sausage is an especially scrumptious and flavorful addition. Using either Italian turkey or chicken sausage also helps to keep this recipe on the healthy side.

Bell Pepper. Adds a wonderful pop of color and added nutrition. Bell peppers are rich in vitamin A and vitamin C. Baby Spinach. An easy way to sneak some greens into your breakfast! When you add the spinach to the skillet, it will seem like far too much. However, it will cook down significantly and be just the right amount.

Hot Sauce. Add a little of your favorite hot sauce for a mild touch of heat. Hash Browns. The ultimate crowd-pleasing casserole ingredient that helps make this recipe extra satisfying. Plus, using frozen hash browns keeps things quick and easy.

Cheddar Cheese. Sharp cheddar cheese won’t get lost amongst other ingredients in this casserole, and its flavor wonderfully complements them too.
