This recipe is for a whole orange chicken cooked in the crockpot, not an asian-style dish. The chicken is flavored with oranges, sweet onion, and an allspice compound butter spread between the skin and the flesh. This helps keep the white meat moist. Place the whole chicken in the with little preparation and forget about it until dinnertime if you can ignore the scrumptious aroma. Instructions are also given for cooking this chicken in the oven.
