Add chicken, potatoes, carrots, celery, onion, garlic, chicken broth, and herbs to the slow cooker.
Cover and cook on low for 6-8 hours or high for 3-4 hours.
Once cooked, shred the chicken using two forks.
For a creamy texture, whisk in cornstarch or flour mixed with water in the last 30 minutes.
Serve with crusty bread, a fresh salad, or your favorite sides.
