What could be better than classic Italian sausage, peppers and onions? The classic trio combined with rigatoni for an irresistible gooey baked pasta.
Bring a large pot of salted water to a rolling boil and cook the rigatoni for 10 to 12 minutes, until al dente. Preheat oven to 350°.2.
In a large skillet, add the Italian sausage and cook over medium heat until browned through, about 10 minutes. Add in the peppers, onion and garlic, and cook until tender, about 5 minutes. Stir in the diced tomatoes and cook for another 3 to 4 minutes, until heated through.3.
Pour the Italian sausage mixture into a large bowl and toss with the rigatoni, marinara sauce and 1½ cups of the Parmesan cheese. Pour the mixture into a 9-inch by 13-inch casserole dish. Top with the remaining cup of Parmesan cheese. Bake for 25 to 30 minutes until the cheese is melted and bubbly. Sprinkle with the parsley and serve.
