This is going to be one of your favorite barbecue recipes: whole bbq turkey cooked directly on the barbecue grill. Not only can it be done, it is actually pretty easy. And it tastes absolutely fabulous.
Place the turkey, breast side up, in a roasting pan. Lightly brush it with oil or melted butter and sprinkle the outside with the seasonings. Add 1/2 cup water to the bottom of the roasting pan. Insert a meat thermometer into the thigh of the turkey (Be careful not to touch the bone with the thermometer. It will affect the temperature reading.)
Place the turkey roasting pan on the grill. Close the lid and roast for 20 minutes, then lower the heat to medium-low. If you have a barbecue with a temperature setting, keep the temperature set at between 325ºF-375ºF. Tent the turkey with aluminum foil to prevent it from over-browning.
Baste your bbq turkey every 15-20 minutes. Add more water to the pan if it dries out during cooking. There should always be water or juices in the pan.
