Creating the perfect Creamy Italian Sausage Rigatoni is simple if you follow these easy steps:

1. Cook the Rigatoni: In a large pot, bring salted water to a boil. Add the rigatoni and cook according to package instructions until al dente. Drain and set aside.

2. Cook the Sausage: In a large skillet over medium heat, add the olive oil. Once hot, add the Italian sausage. Break it apart with a wooden spoon and sauté until browned and cooked through, about 5-7 minutes.

3. Sauté the Onion and Garlic: Add the diced onion to the skillet with the sausage and cook until translucent, about 3-4 minutes. Stir in the minced garlic and sauté for an additional minute until fragrant.

4. Add the Cream: Pour in the heavy cream and stir to combine. Allow it to simmer for a few minutes to thicken.

5. Incorporate Cheese and Seasoning: Add the grated Parmesan cheese and Italian seasoning to the skillet, stirring until the cheese is melted and the sauce is smooth. Season with salt and pepper to taste.

6. Combine Pasta and Sauce: Add the cooked rigatoni to the skillet, tossing it in the creamy sauce until well coated.

7. Serve Warm: Remove from heat and let it sit for a minute before serving.
