Heat 1 tablespoon olive oil in a large, high-sided, heavy-bottomed skillet. Cook sliced mushrooms (seasoned with salt and pepper) on high heat for about 1 or 2 minutes, until lightly browned and softened. Remove half of the cooked mushrooms from the skillet to a plate.
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.
Season with more salt, freshly ground coarse black pepper, red pepper flakes, and smoked paprika, if you like.
Top with the remaining half of the cooked mushrooms.
Notes
This creamy spinach and mushroom gnocchi can be served as a meatless main course or as a side dish.
