Creating this incredible Creamy Sausage Rigatoni is simple if you follow these 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. Brown the Sausage: In a large skillet, heat the olive oil over medium heat. Add the Italian sausage, breaking it apart with a spoon. Cook until browned and cooked through, about 5-7 minutes.

3. Sauté the Aromatics: Add the chopped onion to the skillet with the sausage. Cook for 3-4 minutes until the onion becomes translucent, then stir in the minced garlic and cook for another minute.

4. Make the Sauce: Pour in the heavy cream and chicken broth. Bring to a simmer and sprinkle in the Italian seasoning. Season with salt and pepper to taste. Let it cook for 2-3 minutes until it thickens slightly.

5. Combine Pasta and Sauce: Add the cooked rigatoni to the skillet and gently toss to coat the pasta in the creamy sauce.

6. Add Cheese: Stir in the grated Parmesan cheese until melted and combined. Adjust seasoning, if necessary.

7. Serve Immediately: Remove from heat and transfer to a serving bowl. Garnish with fresh basil leaves, if using.

8. Enjoy: Pair with a green salad or garlic bread for a complete meal!
