Test Kitchen Tips: 

• For food safety, turkey must reach an internal temperature of 165°F. 
• Always thaw a frozen turkey in the refrigerator, not at room temperature. A 12-15 pound frozen turkey will take 2-3 days to thaw in the refrigerator. If pressed for time, this size turkey can be thawed in cold water in 6-9 hours. Be sure to change the water often.
• The roaster oven cooks a turkey in less time than a regular oven, but use a meat thermometer to make sure your turkey is thoroughly cooked.
• Turkey cooked in a roaster oven will be very moist, but less brown than a traditionally roasted turkey. Seasoning rubs add flavor and enhance the appearance of a roaster oven cooked turkey.
