Cooking a turkey involves roasting it in an oven. Roasting is a dry-heat cooking method that uses hot air to circulate around the food, allowing it to cook evenly. The turkey should be placed in a roasting pan and cooked at a high temperature for a certain amount of time. The internal temperature of the turkey should be checked with a thermometer to ensure it is cooked through. Once the turkey is cooked, it should be allowed to rest before carving.
