Breakfast Casserole is one of those everyday, classic recipes that all people everywhere should have in their recipe box. It’s a simple savory dish, but universally loved. This version has all our favorite breakfast items baked into one deliciously cheesy dish.
Make It Your Own
Breakfast Casserole is crazy versatile. Change up the veggies you use, or even the meat. (It’s great with added bell peppers or subbing in some bacon.) Try a different cheese (Monterey Jack is scrumptious.)
It’s obviously the ultimate breakfast to get your day started off right. Pair it up with your favorite waffles or pancakes, like Renae’s easy Bisquick pancake recipe, for the ultimate Sunday morning treat. And if you’re feeling really indulgent and like having a breakfast celebration, you definitely need to give the rabanadas from Recipe Mash a try. That yummy Portuguese French toast pairs perfectly with my delicious sausage and egg breakfast casserole.
Perfect Any Time of Day
But, breakfast casserole is more than just breakfast. It’s also a satisfying midnight snack. Or, cut it into tiny squares to use as appetizers on a brunch table. Even whip one up to serve as “breakfast for dinner” night. That’s a family favorite!
Leftovers warm beautifully, in the microwave, for an after-school snack, too. No matter how or when you serve it, Breakfast Casserole will get rave reviews and put another simple, hearty meal into your expanding recipe repertoire.

A Tip for Baking Potatoes
I’ll let you in on a secret about me. I hate wasting time doing something multiple times, if I can accomplish it in just one session of work.
For instance, I bake potatoes, 8 or 10 pounds, at a time. I scrub them up, prick the skin and then toss them on a *baking sheet. I bake them all at once, on the sheet tray, which makes them super easy to get in and out of the oven.
Baked potatoes re-heat quickly in the oven or microwave, and a baked potato with a green salad is my all-time favorite lunch!
Pre-baked potatoes are also great for casseroles, soups, salads, hash browns, potato pancakes and fried potatoes. They’re already cooked, so you don’t need to overcook other ingredients trying to get them done, like you would if you started with them raw. All they need is to heat through.
It’s great to keep a few already baked potatoes in the fridge, ready to add to my next dish or to warm up for an indulgent lunch break. It’s also great for making recipes like this scrumptious Breakfast Casserole!
How to Make Breakfast Casserole
Start by preheating the oven and greasing a *9×13 pan.
Crumble and brown the ground sausage in a skillet. Drain off the grease and crumble any bigger clumps, so your crumbles are all fairly uniform in size.
Next, grate your baked potatoes. You don’t even need to remove the skins. They will come away on their own as you’re grating. Plus, if a little baked potato skin gets grated into the mix, that’s tasty, too. I use a *4-sided box grater. It’s so much easier to handle and balance on the counter or cutting board, than a flat grater and I get the benefit of all the different grate sizes. It’s another one of those everyday kitchen tools that was a great investment for me.
Add the potatoes to the bottom of your prepared baking pan. Spread them out in an even layer. I salt and pepper this layer. If you are restricting salt, then certainly, adjust to your own tastes and dietary needs.
Drizzle the potato layer with the melted butter.
Mix together the browned sausage, onions, spinach, and garlic.
Once the ingredients in the sausage layer are evenly combined, pour them over the potato layer in your baking pan.
Beat the eggs until they are golden and fluffy. I add salt and pepper to the raw egg mixture. Season it to your own tastes. Stir in the grated cheese. Pour the egg and cheese mixture over the sausage layer.
You may need to redistribute some of the cheese after everything is poured out. And that’s it. It really IS that simple. Your Breakfast Casserole is ready to bake.
Bake at 350° for 45 minutes, until the eggs are firmly set and the cheese is golden brown and crispy on top.
Cut the Breakfast Casserole into squares and serve with a green salad and/or fruit for a fully-balanced and over-the-moon delicious meal. Enjoy!
