Prepare the Ingredients. Chop your potatoes, carrots, celery, and onion into bite-sized pieces. Mince the garlic for that extra savory punch.
Add to Slow Cooker. Place chicken, vegetables, garlic, broth, tomato paste, and seasonings into the crockpot. Stir to combine.
Slow Cook. Cover and cook on Low for 7–8 hours or High for 3–4 hours, until chicken and veggies are tender.
Shred & Thicken. Remove the chicken, chop it into bite-sized pieces, and return it to the pot. If desired, stir in a cornstarch slurry to thicken the broth.
Garnish & Serve. Remove bay leaf, taste for seasoning, and garnish with fresh parsley before serving. Pair with crusty bread or a side salad for a complete meal.
