Arrange the Chicken: Place the chicken breasts in the bottom of the slow cooker, spreading them out evenly.
Make the Gravy Mix: In a medium bowl, whisk together the cream of chicken soup, chicken gravy mix, and chicken broth until smooth.
Cook the Chicken: Pour the gravy mixture over the chicken. Cover the slow cooker and cook on low for about 4 hours, or until the chicken reaches an internal temperature of 165°F (74°C).
Shred the Chicken: Once done, shred the chicken directly in the slow cooker using two forks, allowing it to soak up the gravy.
Add Sour Cream and Season: Stir in the sour cream, then season with kosher salt and freshly ground black pepper to taste.
Serve: Spoon the chicken and gravy over cooked rice or mashed potatoes. Garnish with chopped fresh parsley for a final touch.
