Ingredients
  

  • 19 ounces frozen cheese tortellini
  • 1 pound beef Italian sausage
  • 24 ounces pasta sauce
  • ¼ cup grated Parmesan cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • cups shredded mozzarella cheese
  • Fresh parsley chopped, for garnish

Instructions
 

  • Preheat the oven to 350°F (175°C).
  • Bring a large pot of salted water to a boil. Cook the frozen cheese tortellini according to the package directions for about 3 minutes. Drain and transfer to a large mixing bowl.
  • Meanwhile, cook the beef Italian sausage in a skillet over medium heat, breaking it into small crumbles until fully browned. Drain any excess fat.
  • Add the cooked sausage to the bowl with the tortellini.
  • Stir in the pasta sauce, Parmesan cheese, garlic powder, oregano, and basil until everything is evenly coated.
  • Lightly grease an 8×8-inch casserole dish and spread the Italian Sausage Tortellini Casserole mixture evenly inside.
  • Sprinkle the mozzarella cheese over the top.
  • Cover with aluminum foil and bake for 20 minutes.
  • Remove the foil and broil for 2–4 minutes until the cheese is bubbly and lightly golden.
  • Garnish with chopped parsley before serving.

Notes

  • Serve with garlic bread or a crisp green salad.
  • Substitute beef Italian sausage with ground turkey or chicken if preferred.
  • Add extra mozzarella for an even cheesier casserole.
  • Fresh basil makes a wonderful finishing garnish.
