USDA’s published recommendations for safely roasting a turkey are:
* Set your oven temperature no lower than 325 °F.
* Place your turkey or turkey breast on a rack in a shallow roasting pan.
* For optimum safety, stuffing a turkey is not recommended. For more even cooking, it is recommended you cook your stuffing outside the bird in a casserole. Use a food thermometer to check the internal temperature of the stuffing. The stuffing must reach a safe minimum internal temperature of 165 °F.
* If you choose to stuff your turkey, the ingredients can be prepared ahead of time; however, keep wet and dry ingredients separate. Chill all of the wet ingredients (butter/margarine, cooked celery and onions, broth, etc.). Mix wet and dry ingredients just before filling the turkey cavities. Fill the cavities loosely. Cook the turkey immediately. Use a food thermometer to make sure the center of the stuffing reaches a safe minimum internal temperature of 165 °F.
* A whole turkey is safe when cooked to a minimum internal temperature of 165 °F as measured with a food thermometer. Check the internal temperature in the innermost part of the thigh and wing and the thickest part of the breast. For reasons of personal preference, consumers may choose to cook turkey to higher temperatures.
* If your turkey has a "pop-up" temperature indicator, it is recommended that you also check the internal temperature of the turkey in the innermost part of the thigh and wing and the thickest part of the breast with a food thermometer. The minimum internal temperature should reach 165 °F for safety.
* For quality, let the turkey stand for 20 minutes before carving to allow juices to set. The turkey will carve more easily.
* Remove all stuffing from the turkey cavities.
