Boil salted water in a large pot and cook rigatoni according to package instructions until al dente. Reserve some pasta water, then drain.
In a large skillet over medium heat, add the sausage and cook until browned. Use a wooden spoon to break it into smaller pieces as it cooks.
Stir in garlic and red pepper flakes and cook for about 1 minute until fragrant.
Pour in the cream and chicken broth, then stir to combine. Add Parmesan cheese and season with salt and pepper, mixing until the cheese melts and the sauce thickens.
Add the drained pasta to the skillet, tossing it with the sauce. If it’s too thick, add reserved pasta water a little at a time until reaching the desired consistency.
Plate the creamy rigatoni and garnish with additional Parmesan cheese and fresh basil if desired.
Use mild or spicy Italian sausage based on your preference; both work well in this recipe.
For a vegan version, substitute the sausage with plant-based sausage and use coconut cream instead of heavy cream.
You can prepare the sauce ahead of time. Just reheat it when ready to serve and add the cooked pasta.
