Place the chicken breasts at the bottom of the crockpot.
In a mixing bowl, combine the cream of chicken soup, ranch dressing mix, chicken broth, garlic powder, onion powder, salt, and black pepper. Mix well until combined.
Pour the mixture evenly over the chicken in the crockpot.
Cover the crockpot with the lid and cook on low for 6 hours, or until the chicken is cooked through and tender.
Once cooked, shred the chicken using two forks and stir the shredded chicken into the gravy.
Serve hot over rice or mashed potatoes. Garnish with fresh parsley if desired.
For added flavor, include sliced mushrooms or chopped onions in the crockpot.
If you want a thicker gravy, remove the lid during the last hour of cooking to allow it to reduce.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat on the stovetop or in the microwave.
