Begin by placing the boneless, skinless chicken breasts at the bottom of your crockpot. Generously season the chicken with salt, black pepper, garlic powder, and onion powder to ensure a flavorful base.
In a separate mixing bowl, whisk together the chicken broth, heavy cream, grated Parmesan cheese, minced garlic, and Italian seasoning until fully combined and creamy. This will form the rich sauce that flavors the chicken.
Carefully pour the creamy mixture over the seasoned chicken breasts in the crockpot, ensuring that they are completely submerged for optimal flavor.
Secure the lid on the crockpot and set it to cook on low for 6-7 hours, or on high for 3-4 hours. The chicken should be cooked through and easily shred with a fork by the end of the cooking time.
Approximately 30 minutes before the cooking time is complete, stir in the baby spinach. Re-cover the crockpot, allowing the spinach to wilt gently into the sauce, enhancing both flavor and nutrition.
Once the cooking time is finished, shred the chicken using two forks straight inside the crockpot, mixing it with the creamy sauce for a delectable consistency.
Before serving, taste the dish and adjust the seasoning with additional salt and pepper if needed. Stir everything together until well combined for a uniform flavor.
Notes
Serve over rice or pasta, and garnish with parsley and extra Parmesan for a stunning presentation.
