A 17 pound turkey typically takes about 4 hours in a 325–350°F (163–177°C) oven, but you should always go by internal temperature, not time alone.

Safe target temperatures

  • Roast until the breast reaches 165°F and the thickest part of the thigh reaches about 170–175°F; this is the key food safety and juiciness benchmark.
  • Always use an instant-read thermometer inserted into the thickest part of the thigh without touching bone, and check the breast separately.

Approximate oven times for 17 lb turkey

These are general ranges for a 17-pound whole turkey:

  • At 325°F (un­stuffed): about 4¼–4½ hours.
  • At 350°F (un­stuffed): about 3¾–4 hours.
  • Stuffed at 325°F: roughly 4¼–4¾ hours.
  • Stuffed at 350°F: roughly 3¾–4½ hours.

Time-per-pound rule of thumb

  • Many guides suggest 13–20 minutes per pound for an unstuffed turkey at 325°F, depending on the source and how cold the bird is when it goes in the oven.
  • For a 17 lb turkey, that usually lands you in the 3¾–4½ hour zone, but again, you still confirm with a thermometer rather than relying on the clock.

Simple roasting game plan

  • Pat the turkey dry, season, and optionally rub with butter or oil for better browning.
  • Start it breast-side up on a rack in a roasting pan, loosely tented with foil for the first half of the time to protect the breast, then remove the foil so the skin can brown.
  • Begin checking temperatures 30–45 minutes before the earliest end of the estimated range so you do not overcook it.

Resting time

  • Let the turkey rest loosely tented with foil for 20–30 minutes (up to 45–60 minutes for a large bird) before carving so the juices redistribute and the meat stays moist.

If you share your exact oven temperature and whether the turkey is stuffed, a more tailored time range can be suggested within these guidelines.
