  • 1/2 lb Italian sausage links hot or sweet*
  • 4 oz fresh mushrooms sliced in half
  • 1/4 cup onion chopped
  • 2 cloves garlic minced
  • 8 oz dry rotini pasta
  • 1/2 cup shredded cheddar cheese
  • 2 cups shredded mozzarella cheese
  • 26 oz spaghetti sauce
  • 1 tbsp olive oil


  • Cook spiral pasta as per package directions, but cook only until al dente (pasta will finish cooking in casserole). Drain, rinse and set aside.
  • Slice sausage links into 1/2-inch pieces.
  • Preheat oven to 350 degrees F. Lightly spray a deep 11 x 7-inch baking dish (or a shallow 13 x 9-inch dish)
  • Heat a heavy skillet over medium-high heat. Add the olive oil. When oil begins to shimmer, add the sausage pieces, onion, mushrooms and garlic. Cook, stirring frequently, until sausage begins to brown. Remove from heat.
  • In a large bowl, combine the pasta, sausage mixture, the cheddar cheese, 1 cup of the mozzarella and the spaghetti sauce. Stir well to combine.
  • Turn out into prepared baking dish. Cover with foil and bake at 350 degrees F for 25-30 minutes. Remove foil and top with the remaining mozzarella cheese. Return to oven and bake an additional 10-15 minutes, or until cheese is melted and beginning to bubble.
