This recipe is the best way to cook a whole chicken in the slow cooker! I used Dr. Pepper instead of cola and whiskey instead of bourbon because that is what I had in my cupboard.
Nest chicken parts into slow cooker. Stir together first four ingredients in a small bowl. Sprinkle evenly over chicken.
Whisk together cola soft drink and next 4 ingredients in a small bowl. Slowly pour between chicken pieces (to avoid removing spices from chicken.) Place lemon slices in a single layer on top of chicken.
Cover and cook on HIGH 5 hours (or on low 6 ½ to 7 ½ hours) or until done.
Transfer chicken pieces to a serving platter, discard lemon slices. Skim the fat off the sauces in the slow-cooker and discard. Pour pan juices over chicken and serve.
