Making a whole rotessierie style chicken is a snap in the Crockpot.
Season whole chicken inside and out. Spray slow cooker insert wkith non stick cooking spray for easier clean up. Place chicken on foil balls inside crockpot and cook on high for 3-4 hours. Instant Read thermometer should read 165 degrees when inserted in thickest part of thigh..
I like to use the juices at the bottom of the slow cooker to baste the chicken while it is resting, just to add even more flavor.
Though the skin is flavorful, it doesn't really get crispy with this cooking method.
I use a 6 quart slow cooker and my chicken fits perfectly.
Resist opening the lid to check progress. Slow cookers take a long time to come back up to temperature and cooking time will need to be extended.
Cooking time really varies with slow cookers. If your slow cooker runs hot on the high setting, it may be ready closer to the 3 hour mark. If you are using a larger chicken, it will probably be ready around 4 hours.
