To cook a 21lb turkey at 350°F, it's recommended to roast it for about 3 to 3.5 hours if it's unstuffed, and 3.5 to 4 hours if it's stuffed. Ensure it reaches an internal temperature of 165°F in the thickest part of the breast and thigh before serving. For the best results, cover the turkey loosely with aluminum foil if it begins to brown too quickly, and let it rest for about 20 minutes before carving to redistribute the juices.
