In the bottom of a crock pot, combine the ranch dressing mix, cream of chicken soup, chicken broth, garlic powder, onion powder, and black pepper. Mix well to create a creamy base.
Place the chicken breasts into the mixture, making sure they are well coated.
Cover the crock pot with a lid and set it to cook on low for 6-7 hours or high for 3-4 hours, until the chicken is cooked through and tender.
About 30 minutes before serving, remove the chicken from the crock pot and shred it using two forks.
Return the shredded chicken to the crock pot and stir in the sour cream and half of the shredded cheddar cheese until well combined.
Cover and allow it to cook on low for an additional 30 minutes to heat through.
Before serving, sprinkle the remaining cheddar cheese on top and let it melt slightly.
Garnish with freshly chopped parsley for a pop of color and freshness.
Notes
Serve over rice or mashed potatoes, garnished with parsley.
