Spray the inside of the slow cooker with non-stick cooking spray. Place 3 pounds boneless skinless chicken breasts in the bottom of the slow cooker.
In a medium-sized bowl combine 1 cup low sodium chicken broth, 1 (1-ounce) packet ranch seasoning powder, 1 (0.6-ounce) packet Italian dressing powder, and 1 (0.9-ounce) packet chicken gravy powder. Whisk together until dissolved.
Pour the broth mixture over the chicken in the slow cooker.
Cover and cook on LOW for 5 hours or HIGH for 4 hours.
Shred the chicken using two forks and serve with mashed potatoes or rice!
Notes
Mix 1 tablespoon cornstarch with 1 tablespoon water and stir into the sauce if you want to thicken the gravy.
