Cheesy Sausage, Onion, and Pepper Breakfast Casserole

It has been a while since I’ve made a breakfast casserole. I’ve had the breakfast sausage for a while in the freezer, and while at the grocery store, my girls picked out red, orange, yellow, and green bell peppers. Along with an onion, milk, eggs, and Bisquick, I knew it would make a delicious breakfast casserole! Plus, it was really pretty too, very colorful!

One great thing about a casserole like this, you can make it up ahead of time and keep it in the refrigerator for up to 12 hours before baking it. So, you can make this the night before, wake up, take it out of the refrigerator, preheat your oven, and then bake it.

Also, if you are hesitant about bell peppers, substitute in other vegetables that you like! I would do this again with broccoli or spinach and mushrooms, maybe even spinach, mushrooms, and tomatoes. Or, change out the sausage for bacon or ham. Whatever you would eat in an omelet or you like with your eggs, try in this casserole!

Cheesy Sausage, Onion, and Pepper Breakfast Casserole

What you need:

1 pound breakfast sausage (if there are casings, remove them)
1 small red onion, diced
2 bell peppers, diced (I used 1/2 red, 1/2 orange, 1/2 yellow, and 1/2 green)
2 cups Mexican blend shredded cheese
1 1/4 cups baking mix, such as Bisquick
1 cup milk
9 eggs
1/2 teaspoon paprika
1/2 teaspoon salt
1/4 teaspoon ground black pepper

How to make it:

Preheat oven to 350 F. Spray a 9 x 13 casserole dish with olive oil or non-stick cooking spray.

In a large skillet, break up and brown the breakfast sausage. Add in diced onion and bell pepper. Cook until onions and peppers have softened. Drain the excess grease from the pan, and pour the sausage, onions, and peppers into the casserole dish. Spread the 2 cups of shredded cheese on top.

Meanwhile, in a medium bowl, whisk together the baking mix, milk, eggs, paprika, salt and pepper. Pour evenly into the casserole dish.

Bake in the preheated oven for 30-35 minutes, or until golden brown on top and a knife comes out clean from the center.
