This educational video teaches you how to cook a stuffed turkey. This chart will help you determine approximately how long to roast stuffed and unstuffed turkey. Always use a meat thermometer to gauge how done it is.
For a stuffed turkey, the roasting time may vary up to 30 minutes, depending upon the bird and the oven. Use the meat thermometer to check the temperature of the dressing. The center of the dressing inside the bird (or in a separate baking dish) must reach a temperature of 165 degrees F. for food safety.
For an unstuffed turkey, place the meat thermometer in the thickest part of the thigh, taking care that it does not touch any bone. Roast the turkey until the meat thermometer reaches 180 degrees F.
