For a whole turkey, the safest way to decide “how long do I bake it” is to go by internal temperature , then use time-per-pound as a guideline, not the only rule.

Quick Scoop: Core Rule

  • Roast the turkey until the thickest part of the breast and the innermost thigh each reach 165°F (74°C) on a meat thermometer.
  • Most home-oven methods that start hot and then lower the temperature end up around 13–15 minutes per pound in a 325°F–350°F oven for an unstuffed bird.

Approximate Time-Per-Pound

These are rough estimates for an unstuffed turkey in a conventional oven:

  • At 325°F: about 10–15 minutes per pound , depending on your starting oven blast and how cold the turkey is.
  • Example chart (un-stuffed, common methods):
    • 10 lb: about 2–2½ hours.
* 12 lb: about 2½–3 hours.

* 14–16 lb: around 2–3½ hours, depending on whether you start at a higher temp then lower.

* 18–20 lb: roughly 4–4½ hours at 325°F.

Stuffed turkeys usually need about 30–60 minutes more, and the stuffing itself must also reach 165°F.

Simple Step Pattern

  1. Preheat oven to 400–450°F and roast 20–45 minutes to brown the skin, depending on the recipe.
  1. Lower heat to 325°F and continue roasting until the thermometer in breast and thigh hits 165°F.
  1. Start checking temp early (about 30–45 minutes before the earliest estimated time) so you do not overcook.
  1. Let the turkey rest 30–45 minutes before carving so the juices redistribute.

Safety And Doneness

  • Always trust a thermometer over the clock to avoid undercooked poultry while keeping it juicy.
  • Insert the thermometer into the thickest part of the breast and the inner thigh, without touching bone, and stop baking once both are at 165°F.
