Using this method a turkey will cook in as little as 2 hrs or less! This is a basic recipe. You will get excellent results and you can dress it up with additions of a marinade soak or more seasonings to suit your liking. Roasting time will depend on the size of your turkey, clearly a 22 lb turkey will take longer than a 12 lb bird. Use of a thermometer is paramount here, do not rely on times.
