A 19 lb turkey usually takes about 4 to 4.5 hours at 325°F (163°C) if unstuffed, but you should always go by internal temperature, not time alone.

Basic timing for 19 lb turkey

  • At 325°F, guides for 18–20 lb unstuffed turkeys give a range of about 4 to 4.5 hours.
  • Some home cooks report that a 19–20 lb bird can run closer to 5 hours at 325°F, depending on oven accuracy and how cold the turkey was when it went in.

Stuffed vs unstuffed

  • Unstuffed: Plan roughly 13–15 minutes per pound at 325°F as a broad rule of thumb, which puts a 19 lb turkey in the 4–4.5 hour range.
  • Stuffed: Stuffed birds typically need more time, closer to 15–17 minutes per pound at 325°F, so a 19 lb stuffed turkey can approach 5+ hours. Always check that the stuffing center also hits a safe temperature.

Doneness temperature and safety

  • The turkey is done when the thickest part of the thigh and breast reaches at least 165°F (74°C) on a meat thermometer; this matters more than the clock.
  • If the bird is very cold going into the oven or partially frozen, total time can increase by an hour or more, so begin checking temperature earlier and keep roasting until it’s safely in range.

Practical example for planning

  • For a typical 19 lb unstuffed turkey at 325°F, many cooks plan on about 4.5 hours, start checking internal temperature after 3.5–4 hours, then adjust as needed.
  • After roasting, let the turkey rest 20–30 minutes before carving so juices redistribute and the internal temperature stabilizes.
