Creating Spicy Sausage Rigatoni is easy if you follow these simple steps:

1. Boil the Pasta: In a large pot, bring water to a boil. Add a pinch of salt and the rigatoni. Cook according to package instructions until al dente. Drain and set aside.

2. Cook the Sausage: In a large skillet over medium heat, crumble and add the spicy Italian sausage. Cook until browned and fully cooked, about 5-7 minutes.

3. Sauté the Onion: Add the diced onion to the skillet with the sausage and sauté until translucent, approximately 3-4 minutes.

4. Combine the Sauce: Pour in the marinara sauce and bring to a simmer. Let it cook for about 5 minutes to combine the flavors.

5. Add Cream: Stir in the heavy cream, mixing well. Allow the sauce to cook for an additional 2-3 minutes until slightly thickened.

6. Combine Pasta and Sauce: Add the drained rigatoni to the skillet, tossing to coat the pasta evenly in the sauce.

7. Heat Thoroughly: Continue cooking for another 2-3 minutes over low heat to ensure everything is heated through.

8. Garnish and Serve: Remove from heat, garnish with fresh basil if desired, and serve immediately.
