Cover and cook on high for 2 to 3 hours, or on low for 4 to 6 hours, until the chicken is cooked through and reaches an internal temperature of 165 ℉.

Mix the cornstarch or tapioca flour with 2 tablespoons of water to create a slurry. Stir the slurry into the slow cooker along with the heavy cream, Parmesan cheese, and fresh spinach leaves.

Serve the Tuscan chicken over rice, noodles, mashed potatoes, or as desired. Optionally garnish with chopped fresh basil or parsley and an extra sprinkle of Parmesan cheese.
