This sausage pasta bake is a hearty breakfast casserole that combines tender rotini pasta, savory sausage, a creamy cheese sauce, and a biscuit topping baked until golden. It’s almost like breakfast macaroni and cheese but with extra flavor from eggs, peppers, and seasonings. Perfect for holiday mornings, potluck brunches, or anytime you need a filling dish that serves a crowd.
Preheat oven to 375°F and lightly grease a 9x13 baking dish with nonstick cooking spray.
In a large skillet, add sausage, onion, and red bell pepper. Cook over medium-high heat, stirring frequently, until sausage is browned and no longer pink. Drain grease if needed. Stir in salt, garlic powder, paprika, and black pepper.
Add cooked rotini pasta to the prepared baking dish. Spread sausage mixture evenly over the pasta.
In the same skillet, melt butter. Add flour and whisk constantly for 1 minute to form a roux. Slowly whisk in milk, a little at a time, until smooth. Bring mixture to a gentle boil, then reduce heat and simmer 2–3 minutes until thickened. Remove from heat and stir in 1 cup of shredded cheese until melted.
Sprinkle 1 cup of cheese over the sausage and pasta in the baking dish. Pour cream sauce on top and stir gently so everything is coated
In a medium bowl, whisk eggs. Stir in the remaining 1 cup of cheese. Add biscuit pieces and toss to coat. Spread biscuit mixture evenly over the pasta and sauce
Place dish in the oven and bake for 25 minutes, or until a knife inserted in the center comes out clean and the middle is hot. Let casserole rest for 5 minutes before serving warm.
