Heat the olive oil in a large, heavy-bottomed skillet over medium heat. Add the crumbled Italian sausage and cook for about 5 minutes until it's no longer pink, breaking it up as it cooks. Drain any excess grease.

To the same skillet with the cooked sausage, add the uncooked rigatoni, chicken broth, heavy cream, minced garlic, Italian seasoning, and tomato sauce. Give everything a good stir to combine.

Bring the mixture to a gentle boil over medium heat. Cover with a lid and let the pasta cook for about 10-15 minutes, stirring frequently to prevent sticking. Cook until the pasta reaches al dente texture and the sauce thickens up nicely.

Add the fresh spinach to the skillet and stir until it wilts to your liking, about 2 minutes. Alternatively, remove the skillet from heat, top with spinach, cover with the lid, and let stand for about 4 minutes until the spinach wilts in the residual heat.

Season with salt, freshly ground black pepper, and red pepper flakes to taste. Remember, the sausage might already be salty enough, so taste before adding extra salt. For a thicker sauce, simply cook a few minutes longer.
