Preheat the oven to 180 0C. Place the chicken in a shallow oven proof roasting pan that fits the chicken comfortably. Place on a rack if preferred. Roast for about 45 minutes to 1 hour. Use extra marinade in the packet to baste during cooking. Chicken must always be cooked thoroughly. Insert a skewer into the thickest part of the chicken between the leg and thigh. If the juices run clear, it is ready.
