Italian Sausage Rigatoni is a delicious comfort food pasta dish. Made with flavorful sausage and hearty rigatoni pasta in a rich tomato sauce. Perfect for busy weeknights.
Bring a pot of water to boil on medium high heat. Once boiling add in 5-6 Tablespoons of salt. Add the rigatoni. Cook for only 5 minutes, reserving ½ cup of the pasta water. Drain the rest. Pasta will finish cooking in the sauce.
While pasta is cooking, add olive oil to a large skillet on medium high heat. Fully cook the Italian sausage until it is no longer pink.
Add in the onion and cook for another 2-3 minutes until softened. Drain the fat.
Add the garlic, 1 teaspoon of the Kosher salt, black pepper, and red pepper flakes.
Add in tomato paste, sun dried tomatoes, and thyme, cooking for one minute.
Add the whole peeled tomatoes and heavy cream. Simmer sauce for 8-10 minutes covered, until slightly thickened.
Add in Spinach, cooked pasta, and fresh basil. Simmer for 5 more minutes (add some pasta water if needed to finish cooking the pasta).
