Heat olive oil in a large skillet over medium heat. Add the crumbled Italian sausage and cook for about 5 minutes until browned. Break it into smaller pieces as it cooks, then drain any excess grease.
02 -
Add the uncooked rigatoni, chicken broth, heavy cream, minced garlic, Italian seasoning, and tomato sauce to the skillet with the sausage. Stir well to make sure the pasta is coated evenly.
03 -
Bring everything to a gentle boil, stirring occasionally to prevent sticking. Cover the skillet and let it simmer for 10-15 minutes until the pasta is al dente and has absorbed the flavors of the sauce.

Once pasta is tender, add the fresh spinach to the skillet. Stir for a few minutes until wilted, or cover and let the residual heat wilt the spinach for about 4 minutes.

If you want a thicker sauce, cook uncovered for a couple more minutes. Season with salt, pepper, and red pepper flakes if desired. Remember the sausage already adds saltiness, so taste before adding more salt.
