1. Season the chicken: Start by seasoning the boneless, skinless chicken breasts with garlic powder, black pepper, and a light sprinkle of salt.

2. Mix the gravy base: In your slow cooker, whisk together the chicken gravy mix, cream of chicken soup, and water until mostly smooth.

3. Add the chicken: Place the seasoned chicken breasts into the slow cooker, ensuring they’re submerged in the gravy mixture.

4. Cook low and slow: Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours until the chicken is tender and easily shreds.

5. Shred and finish: Remove the cooked chicken from the slow cooker and shred it into bite-sized pieces. Return it to the slow cooker and stir in the sour cream. Warm for about 15 minutes before serving.

6. Serve and enjoy: Serve over mashed potatoes, rice, or egg noodles, topped with sliced green onions if desired.
