STEP TWO: COMBINE INGREDIENTS
Add the spaghetti, crushed tomatoes, broth, heavy cream and crushed red peppers (if using) to the stockpot and bring it to a boil.
STEP THREE: STIR TO COOK
Boil the ingredients for 15 to 20 minutes, turning them frequently, until the pasta is cooked and the sauce becomes thick and creamy. Serve with Parmesan and fresh basil, if desired.
