Turkey can be safely reheated in a conventional oven or a microwave. Foster Farms recommends cutting the turkey into parts and slices rather than trying to reheat it whole.
Spread the slices, legs or wings onto an oven-proof pan in a single layer when reheating turkey with a conventional oven. Moisten the parts with a little water, and cover with foil, then heat at 350 degrees for approximately 35 to 45 minutes or until the meat is 165 degrees Fahrenheit.
For a microwave oven, use a microwave-safe pan, and cover the meat with plastic wrap. Rotate the dish in order to heat the meat evenly. When heating two to four slices, set the timer for 1 to 2.5 minutes.
