Step 1

Heat a large pot over medium heat. Add oil. Add onions and cook for 7-8 minutes until softened. Add garlic cloves and sausage. Cook for 7-8 minutes more until sausage begins to brown.

Step 2

Fill a large pot with water. Bring to a boil over high heat. Add a generous amount of salt to the water to infuse the pasta with flavor. Add pasta and cook according to package instructions.

Step 3

Add tomatoes. If using whole tomatoes, blend in a blender until smooth. Add fresh basil, oregano, red pepper flakes, salt, and pepper. Let it come to a boil and reduce.

Step 4

Stir in heavy cream and 1 cup of parmesan cheese, reserving 1/2 cup for garnish. Reduce heat to medium-low and let it simmer.

Step 5

Drain the pasta and add to the sauce. If you want it to be less "saucy" let the sauce simmer for 10 minutes longer.

Step 6

Taste for seasonings. Serve with remaining 1/2 cup of parmesan cheese and fresh basil.
