To the same skillet with the half of cooked mushrooms, add uncooked potato gnocchi, chicken broth, heavy cream, minced garlic, Italian seasoning, smoked paprika, and ¼ teaspoon salt.
Bring to a boil on medium heat and stir everything well. Cover with lid, and allow the gnocchi to cook for about 5 minutes on medium heat, while the sauce boils.
Add fresh spinach, and cook on medium heat, stirring frequently for 5 minutes until the spinach wilts to your liking. Cook longer if you would like a thicker sauce.
