Spray the slow cooker with non-stick cooking spray and lay 1 pound halved baby potatoes and 2 cups baby carrots on the bottom. Lay 4 boneless skinless chicken breasts on the vegetables.

In a medium bowl, whisk together 1 (10.5-ounce) can cream of chicken soup, 1 package dry ranch dressing mix, and ½ cup whole milk.

Pour the ranch mixture over the chicken and vegetables and cook on LOW for 4-5 hours until the chicken is fully cooked and the vegetables are tender.

Serve the chicken and vegetables fresh with the ranch sauce and parsley for garnish.
