  • The turkey is done only when the thickest part of the thigh, the breast, and the center of any stuffing all reach the USDA-safe 165°F, checked with a thermometer.
  • Thaw the turkey in the refrigerator, not on the counter — the USDA warns that thawing at room temperature lets the outer layer enter the bacteria danger zone.
  • These cook times are estimates. Start checking the temperature early, and tent the breast with foil if it browns before the thigh is done.
  • Add a target serving time above to get a full backward schedule — when to thaw, roast, temperature-check, and rest.

How to use this calculator

  1. Enter the turkey's weight

    Type the weight in pounds — thaw and roast times both scale with it.

  2. Choose stuffed or unstuffed

    A stuffed turkey takes longer, because the stuffing must also reach a safe temperature.

  3. Add your serving time (optional)

    Enter when you want to serve, and the calculator works backward into a full schedule.

  4. Roast to 165°F

    Follow the schedule and pull the turkey when the thigh, breast, and stuffing all reach the USDA-safe 165°F.

Add about 30 minutes for a stuffed turkey. The bird is done only when the thigh, breast, and any stuffing all reach the USDA-safe 165°F.

Tips & best practices

  • Start thawing early — refrigerator thawing is slow but safe, and it is far better to have a thawed turkey waiting than a frozen one on the morning of.
  • Use a leave-in probe thermometer in the thigh so you can track the temperature without opening the oven.
  • Build a generous buffer into your schedule — a resting turkey holds its heat well, so finishing early is never a problem.
  • Cook the stuffing in a separate dish: the breast stays juicier and the stuffing reaches a safe temperature without overcooking the bird.
  • Tent the breast with foil if it browns too fast — it shields the surface while the thigh catches up.
  • Pull the turkey at 165°F in the thigh; carry-over heat during the rest carries it the rest of the way.

Frequently asked questions

How long does it take to thaw a turkey?
In the refrigerator, allow about 24 hours of thawing for every 4 to 5 pounds. A 16-pound turkey takes roughly 4 days. Refrigerator thawing is the only method the USDA recommends as completely safe — never thaw a turkey on the counter.
How long do I cook a turkey per pound?
At 325°F, an unstuffed turkey takes roughly 13 minutes per pound for an 8–12 lb bird, about 12 minutes per pound for 12–14 lb, around 11 minutes per pound for 14–18 lb, and closer to 10 minutes per pound for 18 lb and up. A stuffed turkey takes about 30 minutes longer overall.
What internal temperature should a turkey reach?
The USDA-safe minimum is 165°F. Check the thickest part of the thigh, the thickest part of the breast, and — if the bird is stuffed — the center of the stuffing. All three must reach 165°F before the turkey is safe to eat.
Is it safe to cook a stuffed turkey?
It can be, but it takes longer and carries more risk, because the stuffing in the cavity must also reach 165°F. By the time it does, the breast is often overcooked. The USDA notes that cooking the stuffing in a separate dish is the safer and more reliable choice.
Why do I need to rest a turkey before carving?
Resting for at least 30 minutes (up to an hour for a large bird) lets the juices redistribute through the meat instead of running out when you carve. The internal temperature also keeps climbing slightly from carry-over heat during the rest.
Can I thaw a turkey faster if I forgot?
Yes — the USDA cold-water method thaws about 30 minutes per pound. Keep the turkey in its leakproof wrapper, submerge it in cold tap water, and change the water every 30 minutes. A turkey thawed this way must be cooked immediately.
Why is my turkey cooking faster or slower than the estimate?
Oven calibration, how cold the turkey was going in, whether it is stuffed, the pan, and how often the oven door opens all change the real time. Treat the calculated time as a planning estimate and rely on a thermometer for doneness.
Should I cover the turkey while it roasts?
Roast it uncovered for browned, crisp skin. If the breast browns well before the thigh reaches 165°F, tent that area loosely with foil for the rest of the cook to slow the browning without steaming the skin.
