Italian Sausage & Alfredo Pasta Bake

This Italian Sausage & Alfredo Pasta Bake is easy to make and is fairly economical. You could add other veggies if you'd like, but usually, I like to keep it pretty simple. I like to keep my veggies "noticeable" in this dish, however, feel free to make them smaller if you want.

Ingredients

▢ 1 pound penne, or other pasta
▢ 1 jar Alfredo sauce, or use homemade Alfredo sauce
▢ 1 pound Italian sausage, casings removed
▢ 1 tablespoon butter
▢ ½ cup red onion, chopped
▢ ½ cup green bell pepper, chopped
▢ 4 ounces Mushrooms, chopped
▢ 4 – 6 ounces Mozzarella cheese, shredded

Instructions

Preheat oven to 375°F. Spray a 9×13-inch baking pan with cooking spray and set aside.
Cook pasta according to package directions and drain.
Meanwhile, in a skillet, brown and crumble the sausage over medium-high heat until no longer pink. Drain. Set the sausage aside.
In the same skillet, melt the butter. Saute the red onion and bell pepper for 2-3 minutes. Add the mushrooms and continue to saute for an additional 2-3 minutes.
In a large bowl (or the same pan the pasta was cooked in), combine the pasta, sausage, veggies and Alfredo sauce. Mix well. Spread evenly into the prepared 9×13-inch pan. Top with Mozzarella cheese.
Bake 20-30 minutes, or until the cheese is melted and the mixture is heated through. Serve immediately.

This is perfect with any short cut pasta!
