Layer Ingredients:
Add chicken, carrots, celery, onion, garlic, and potatoes to the slow cooker.
Season & Add Broth:
Sprinkle in thyme, rosemary, and bay leaf. Add tomato paste and season with salt and pepper. Pour in chicken broth and stir gently to combine.
Cook:
Cover and cook on low for 6–7 hours or high for 3–4 hours, until chicken and vegetables are tender.
Thicken (Optional):
If you prefer a thicker stew, mix cornstarch and water in a small bowl and stir it into the stew during the last 30 minutes of cooking. Let it simmer and thicken slightly.
Finish & Serve:
Remove bay leaf. Adjust seasoning if needed. Garnish with fresh parsley and serve warm with crusty bread.
