Creating this incredible Creamy Sausage Rigatoni is simple if you follow these easy steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add rigatoni and cook according to package directions until al dente. Drain and set aside.
2. Sauté the Sausage: In a large skillet, heat olive oil over medium heat. Once hot, add the Italian sausage, breaking it apart with a wooden spoon. Cook until browned and cooked through, about 5-7 minutes.
3. Add Aromatics: Add the chopped onion and minced garlic to the skillet. Sauté for an additional 3-4 minutes until the onion is translucent and fragrant.
4. Stir in Tomatoes: Pour in the diced tomatoes (including the juice) and red pepper flakes if using. Stir to combine and let simmer for 2-3 minutes.
5. Incorporate Cream: Reduce the heat to low and slowly add the heavy cream, stirring continuously until well combined.
6. Mix in Cheese: Gradually add the grated Parmesan cheese, stirring until melted and the sauce is creamy. Season with salt and pepper to taste.
7. Combine Pasta and Sauce: Add the cooked rigatoni to the skillet and stir until the pasta is evenly coated in the creamy sauce.
8. Heat Through: Allow everything to heat together for an additional 2-3 minutes, so the flavors meld.
9. Garnish and Serve: Remove from heat, and garnish with fresh basil if desired. Serve hot and enjoy!
