Ingredients
1 lb mild Italian sausage (or hot, if you prefer)
1 tablespoon olive oil
½ yellow onion, diced
2 cloves garlic, minced
1 tablespoon Italian seasoning
½ teaspoon salt
¼ teaspoon black pepper
24 ounces marinara sauce (1 jar)
3 cups water
16 ounces rigatoni
½ cup heavy cream (or half-and-half)
1½ cups shredded mozzarella cheese
½ cup grated Parmesan cheese
Fresh parsley, for garnish
Step by Step Instructions

Photo 1. Set the Instant Pot to Sauté/Brown. Add the Italian sausage and break it into small pieces with a spatula as it browns.
Photo 2. Add the olive oil and diced onion. Cook 4–5 minutes until the onion softens.

Photo 3. Stir in the minced garlic and Italian seasoning and cook one more minute to bloom the flavors.
Photo 4. Pour in the marinara sauce, then add the water.

Photo 5. Stir gently to combine the sauce and liquids.
Photo 6. Add the rigatoni. Do not stir it into the sauce; simply press the pasta down so it’s submerged in the liquid. This helps avoid a burn warning.

Photo 7. Keep the pasta mostly undisturbed—just ensure it’s covered by the liquid.
Photo 8. Close the lid, seal the vent, and cook on HIGH pressure for 6 minutes. Perform a quick release when the time is up. Open the pot, then stir in the heavy cream, mozzarella, and Parmesan until the sauce is smooth and creamy.

Serve hot, topped with fresh parsley. This dish is a family favorite—rich, comforting, and ready in minutes.
