In a small bowl, combine the salt, pepper, onion powder, garlic powder, paprika, oregano, and parsley. Stir to combine and set aside.
Roughly chop the potatoes, carrots, celery, onion, and garlic. Add the veggies to the bowl of your slow cooker.
Pour the chicken stock and liquid smoke over the veggies.
To prepare the chicken, remove the giblets from the cavity of the chicken and dispose of them. Pat the chicken dry.
Drizzle the olive oil over the chicken. Using a brush or your hands make sure the chicken is fully coated.
Sprinkle the seasoning over the whole chicken making sure it’s fully seasoned. Add the remaining seasoning to the inside of the chicken.
Place the chicken on top of the veggies in the slow cooker bowl. Cover and set on HIGH and cook for 4 to 4½ hours. (You can also set the slow cooker to LOW and cook for 8 hours.)
After 4 hours, check the internal temperature of the chicken in the thickest part with a food thermometer to ensure it reads 165 degrees F to ensure it's done. This is important as cooking times may vary based on the size of the chicken and the slow cooker model.
Remove the chicken from the slow cooker and place on a platter. Slice the chicken and arrange the vegetables around it. Serve and Enjoy!
