In a large, high-sided skillet, heat olive oil over medium heat. Add the crumbled Italian sausage and cook for about 5 minutes, breaking it into smaller pieces, until browned and cooked through. Drain any excess grease.

To the same skillet, add uncooked rigatoni, chicken broth, heavy cream, minced garlic, Italian seasoning, and tomato sauce. Stir to combine, ensuring the pasta is well-coated.

Bring the mixture to a gentle boil over medium heat. Stir occasionally to prevent sticking. Cover the skillet and let it cook for 10–15 minutes, or until the pasta is al dente and has absorbed the flavors.

Stir in the fresh spinach and cook for a few minutes until wilted. Alternatively, remove the skillet from heat, cover, and let the residual heat wilt the spinach for about 4 minutes.
05 -
If a thicker sauce is desired, cook uncovered for an additional few minutes, stirring occasionally.

Remove from heat and season with salt, freshly ground black pepper, and red pepper flakes if using. Serve hot.
