  • 1 16 oz box pasta I used Rigatoni
  • 1 cup mini pepperoni
  • 1 green pepper chopped
  • 1/2 cup diced onion
  • 2.25 oz can sliced black olives
  • 2 cups shredded mozzarella cheese
  • 1 lb Italian sausage casings removed
  • 1 teaspoon Italian seasoning
  • 1 24 oz jar marinara sauce


  • Preheat oven to 350 degrees.
  • Cook pasta according to directions on box.
  • Cook Italian sausage in a skillet over medium high heat. Cook until browned, about 5-7 minutes. Use a wooden spoon to crumble sausage while cooking.
  • Drain excess fat.
  • Drain pasta and add back into pot. Stir in sausage, peppers, onions, olives, pepperoni, seasoning, sauce and 1 cup of cheese. 
  • Place pasta mixture in greased 9x13 casserole dish. Top with remaining mozzarella cheese.
  • Bake for 30 minutes or until heated through.


  • If you know you are going to make this meal, pre-chop the veggies and pre-cook your sausage. When you are ready to assemble, everything will be ready to mix together. 
  • Salt your pasta water while cooking the pasta. It is a great way to season the pasta itself. 
  • Like your casserole super cheesy? Add another 1/2 cup mozzarella to the top.
  • This pasta bake will keep 4-5 days covered in the refrigerator.
