1 tablespoon chopped fresh parsley, or to taste (Optional)
Instructions
Stir chicken broth, onion, carrot, rice, celery, mushrooms, garlic, salt, and pepper together in a 6-quart slow cooker. Nestle in chicken, thyme, and bay leaves.
Cover and cook on Low until chicken and wild rice are tender, about 7 hours. An instant-read thermometer inserted near the bone of each breast should read 165 degrees F (74 degrees C).
Remove chicken from the slow cooker. Increase heat to High. Discard chicken bones and shred meat; set aside. Discard thyme sprigs and bay leaves.
Whisk milk and flour together in a medium bowl. Stir into slow cooker and cook on High until thickened, about 10 minutes. Gently stir in chicken. Garnish with parsley.
