This Cheesy Sausage Egg Casserole is the perfect brunch or breakfast recipe! Eggs and sausage and cheese all baked up in a pan, everyone loves this recipe!

Remember my Christmas Eggs? This is another version of that recipe, but with SAUSAGE! Goodness knows, this was a HIT.

Why we love this recipe

I can tell you this egg casserole tastes AMAZING: there is never any left whenever I serve it – it’s always a hit, no matter when I make it or what I put inside. (Remember when I used green chiles?)

This sausage egg casserole is full of eggs and sausage and cheese and has no bread – which is why I love it. When I serve brunch I like to serve something sweet, like cinnamon rolls or French toast. When you’re eating muffins, you don’t need bread in your eggs.

An easy egg casserole full of delicious breakfast sausage is what you need for Sunday brunch…or just a random Tuesday. We often make this on Sunday morning and then freeze slices for during the week. Even my picky eater loves this casserole!

Ingredients Needed

  • Sausage: I use 1 lb bulk breakfast sausage
  • Butter: use 1/2 cup melted butter
  • Cottage Cheese: Don’t be scared!! I don’t like cottage cheese but I love it in this recipe – you won’t even know it’s there. It adds body and protein and more cheesy flavor.
  • Cheese: shredded cheddar cheese is my favorite for this one, but you can use your favorite cheese. Sharp cheddar cheese is also amazing.
  • Eggs: you need eggs, obviously! I use 10 large eggs

How To Make Sausage Egg Breakfast Casserole

  1. Crumble sausage and cook in a large skillet over medium-high heat. Cook until no longer pink.
  2. Whisk the eggs in a large bowl until completely mixed.
  3. Add butter, flour, baking powder, pepper, and salt into the eggs.
  4. Add cottage cheese.
  5. Add the shredded cheese and crumbled sausage.
  6. Pour into prepared baking dish and bake for 30-40 minutes or until browned and set in the middle. Cool 5-10 minutes before slicing and serving.

Expert Tips

  • You can also add cooked onion, bell peppers, and/or mushrooms to the egg mixture. Change up the flavor as you like!
  • Allow it to sit for 10 minutes before slicing.

Storing Leftovers

  • Store leftovers in an airtight container in the refrigerator. We like to slice leftovers into serving squares and freeze them in sandwich bags. Then it’s easy to just reheat for a quick breakfast!
  • You can also freeze slices in sandwich bags.
  • You can make it ahead: I know a lot of egg casseroles are overnight egg casseroles, but you don’t have to do this one overnight. You can cook your sausage the night before, if you want, but it whisks together in about 10 minutes and then goes straight into the oven. If I can make this on Christmas morning, believe me, it’s easy enough to make for your family for brunch.

FAQ

Can you cook the sausage the night before?

Yes, drain the fat and store in the refrigerator.

What cheese is best in egg casserole?

Any kind you like! I love cheddar, Monterey Jack, or mozzarella in this.

How do you keep eggs warm while finishing breakfast?

If the casserole finishes before the rest of the meal, cover it with aluminum foil until ready to serve.

Recipe Notes

Use any kind of sausage and any kind of cheese!
If your casserole browns too quickly, tent with foil. My oven tends to bake hotter on top, so I often do this to make sure it cooks all the way through without getting too brown.

  1. This is the only breakfast casserole I’ll make from now on. Love that it doesn’t have potatoes or bread in it, and it’s easily customizable. I’ve added fresh mushrooms, diced fresh tomatoes, green onions, etc., at different times and it’s always been delicious.

    1. Honestly I recommend doing your own calculation, my facts aren’t guaranteed to be accurate. I’m also not a nutrition expert.

  3. This was an absolute family pleaser!! I added some fresh diced tomatoes, scallions and roasted green tomatillo sauce to give it a bit of acid and kick. The three of us nearly finished the entire casserole. This is now our go-to favorite!

  4. This is my go-to Christmas morning breakfast casserole. Much better than the ones I’ve made with potatoes or bread. Kids are now young adults and asked them if they wanted something different this year – the answer was no way! Sometimes I use hot breakfast sausage to kick it up a little.
    Thank you for sharing the recipe.
