  • 1 tablespoon olive oil
  • 1 pound Italian sausage casings removed
  • 2 cloves garlic minced
  • 1 green pepper diced
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 29 ounces crushed tomatoes
  • 2 cups chicken broth
  • 1/2 tablespoon dried basil
  • 1/2 tablespoon dried oregano
  • 1/2 teaspoon crushed red pepper flakes
  • 8 ounces rotini
  • 2 cups shredded mozzarella
  • pepperoni for topping
  • sliced olives for topping
  • shredded parmesan for topping


  • Preheat the oven to 350 degrees.
  • Heat the oil in a large oven proof skillet over medium heat. Add the Italian sausage, breaking it up as you cook. When it is completely broken up but before it has begun to brown, add the green pepper and garlic. Season with salt and pepper. Sauté until the peppers have begun to soften, about 5 to 7 mintues.
  • Add crushed tomatoes, chicken broth, red pepper flakes, basil, and oregano, stirring to combine.
  • Stir in rotini. Bring to a boil and then reduce heat and simmer for 10 to 15 minutes (or until the rotini just has a small bite to it), stirring occasionally.
  • Stir in 1/2 cup of the mozzarella. Top with the rest of the cheese, the pepperoni, and the olives. Put it in the preheated oven and cook for 5 to 10 minutes or until the cheese has melted.
