Ingredients you’ll need

- diced peppers and onions
- black pepper, smoked paprika, cayenne
How to make sausage breakfast casserole
- Cook the sausage and veggies: Cook the diced peppers and onions in a little olive oil over medium-high heat until cooked and softened. Add in the sausage and cook for about 10 minutes, making sure to break it up into crumbles with your spatula. Remove from heat and blot any excess grease from the sausage with paper towels. Then preheat the oven to 350ºF.
- Prepare the eggs: Whisk together the eggs, milk, black pepper, smoked paprika and cayenne in a large mixing bowl.
- Prepare the dough: Lay out the crescent roll dough into a lightly oiled 9×13 rectangular baking dish. Pinch together all the seams found in the dough so you have one uniform sheet of dough.
- Assemble the casserole: Add the cooked sausage and veggies on top of the dough. Pour in the egg mixture and bake for 35 minutes, or until the center of the casserole is set.
Make ahead sausage breakfast casserole
If you’re hosting a breakfast or brunch and want to make this ahead of time so you’re not stressed out about getting things done in the morning, you can totally make this casserole ahead of time!
Simply assemble the casserole the night before, cover it with plastic wrap and place it in the fridge overnight. When you’re ready to make it in the morning, remove it from the fridge and bake it in a 350ºF oven for 35 to 40 minutes, or until the center is completely set and cooked through.
The entire dish also reheats well, so you could also bake the casserole the night before and reheat it for 5 minutes in a 350ºF until the next morning. Whichever you prefer!
Substitutions and variations
- If you’re not a fan of pork sausage and want to cut down on the fat, you can use turkey or chicken sausage instead.
- Got leftover ham, turkey or chicken in the fridge? Use that instead of sausage. Just be sure to season it with a generous pinch of salt so it isn’t bland.
- Feel free to add in any veggies you have in the fridge – mushrooms, zucchini, tomatoes, diced green chiles, chopped kale.
- Like cheese? Top your casserole with a cup of shredded mozzarella, colby jack or cheddar cheese!
