If you are working with precooked smoked turkey, all you need to worry about is heating the meat to a comfortable temperature. Because it is precooked, the meat has been prepared and brought to a safe cooking level. Warming smoked turkey can be done slowly in an oven set to a lower temperature of 200 to 250 degrees Fahrenheit. You want to wrap the turkey in tin foil so it does not dry out in the oven. If you are in a hurry, then you can always stick the turkey legs in the microwave until they suite your taste.
