Video transcript

A 21 lb turkey should cook for approximately 4 to 4.5 hours at 325°F (163°C). It's important to use a meat thermometer to ensure the internal temperature reaches 165°F (74°C) at the thickest part of the turkey. Covering the bird with aluminum foil for the first 2 hours can help prevent over-browning, and don't forget to let it rest for about 20-30 minutes before carving to retain its juices.
