Season the Chicken: Pat the chicken dry and season with salt, black pepper, and Italian seasoning.
Sear the Chicken: Heat olive oil in a skillet over medium-high heat. Cook the chicken for 4-5 minutes per side until golden brown. Remove and set aside.
Prepare the Cream Sauce: In the same skillet, sauté garlic until fragrant. Add chicken broth, heavy cream, and Parmesan cheese, stirring until the sauce begins to thicken.
Add the Spinach: Stir in the fresh spinach and cook until wilted.
Combine and Serve: Return the chicken to the skillet and let it simmer in the sauce for a couple of minutes. Serve hot over pasta, rice, or with crusty bread.
