Cooking Tips: Cooking a Turkey on a Gas Grill
Before you set your turkey out on the open blue flame, check out how your grill actually works. You'll want indirect heat to cook your turkey on the grill. If your gas grill has only one large burner, place a pan of water under the grate to create indirect heat. Place the turkey in a roasting pan and place on top of the grill. If the grill has two or three burners, try turning off one burner and then placing the turkey away from the flame. Preheat the grill just like you would an oven.
When using a gas grill, always follow manufacturer's directions for cooking times. But if your grill has its own thermometer or you place an oven thermometer on the grate, you can monitor the cook temp just as you would in an oven. Baste the turkey every half hour or so, and check the temp while you're at it, remembering that rain or wind could be a challenge to maintaining 350 degrees F.
And of course, make sure your gas tank is actually full. Half-cooked turkey just doesn't fly.
