How Long To Cook Turkey Per Lb

ByLily

Timing a turkey by weight works the same whether you measure in pounds or kilograms. Most cooks want a simple answer to how long to cook turkey per lb, and the standard rule is 13 to 15 minutes per pound for a stuffed bird and 15 to 20 minutes per pound for an unstuffed one at 325°F. That single number gets you close, but the real key is checking the internal temperature before you pull it from the oven.

This guide breaks down cooking times by weight, explains why stuffed and unstuffed birds differ, and shows you exactly where to place your thermometer. By the end, you will know how to plan your roast so the turkey lands on the table hot and juicy.

The Basic Rule For Cooking Turkey By Weight

Oven temperature matters as much as weight. The USDA recommends roasting at 325°F, and that is the temperature all the times below assume. If you cook hotter, the outside browns before the center is safe. If you cook lower, the bird dries out before it finishes.

Here is the quick reference for an unstuffed turkey at 325°F:

  • 8 to 12 lb: 2 hours 45 minutes to 3 hours
  • 12 to 14 lb: 3 hours to 3 hours 45 minutes
  • 14 to 18 lb: 3 hours 45 minutes to 4 hours 15 minutes
  • 18 to 20 lb: 4 hours 15 minutes to 4 hours 30 minutes
  • 20 to 24 lb: 4 hours 30 minutes to 5 hours

These times are guides, not guarantees. Oven calibration varies, and a bird that sits at room temperature for 30 minutes before roasting cooks faster than one straight from the fridge.

How Long To Cook Turkey Per Lb

When people ask how long to cook turkey per lb, they usually want one number they can multiply. Use 15 minutes per pound as your starting point for an unstuffed turkey, then add 15 to 30 minutes of buffer time. A 16 lb bird, for example, lands around 4 hours.

Stuffed turkeys need more time because the dressing insulates the center. Plan on 13 to 15 minutes per pound, but never trust the clock alone. The stuffing must reach 165°F too, and that often pushes total time past the unstuffed estimate.

Unstuffed Turkey Times Per Pound

Unstuffed birds cook faster and more evenly. The chart below uses 325°F and a thawed turkey.

  • 10 lb: about 2 hours 30 minutes
  • 12 lb: about 3 hours
  • 15 lb: about 3 hours 45 minutes
  • 18 lb: about 4 hours 15 minutes
  • 22 lb: about 4 hours 45 minutes

Add roughly 15 minutes per pound if your oven runs cool. Subtract nothing if it runs hot, since undercooked poultry is a food safety risk.

Stuffed Turkey Times Per Pound

Stuffing a turkey adds 30 to 45 minutes to the total cook. The center of the stuffing is the last part to hit a safe temperature, so the bird often overcooks near the breast while you wait.

  • 12 lb stuffed: 3 hours 30 minutes to 4 hours
  • 16 lb stuffed: 4 hours to 4 hours 30 minutes
  • 20 lb stuffed: 4 hours 45 minutes to 5 hours 15 minutes

If you want the best of both worlds, roast the turkey unstuffed and bake the dressing in a separate dish. You get faster cooking and a safer result.

Why Internal Temperature Beats The Clock

Weight gives you a plan, but a thermometer gives you the truth. The turkey is done when the thickest part of the thigh reads 165°F and the breast reads 165°F. Check both spots and avoid touching bone, which heats faster and gives a false reading.

Let the bird rest for 20 to 30 minutes before carving. The temperature rises another 5 to 10 degrees during the rest, and the juices redistribute through the meat.

Where To Place Your Thermometer

  1. Insert the probe into the inner thigh, near the body but not touching bone.
  2. Take a second reading in the thickest part of the breast.
  3. If the turkey is stuffed, check the center of the stuffing separately.
  4. Wait 15 seconds for a stable reading before you trust the number.

Factors That Change Cooking Time

Two birds of the same weight can finish 30 minutes apart. Here is what moves the needle.

  • Oven accuracy: a 25 degree difference can add or remove 30 minutes.
  • Pan material: dark pans brown faster, so you may need to tent the breast with foil.
  • Starting temperature: a room temperature bird cooks quicker than a cold one.
  • Stuffing: a stuffed cavity slows heat transfer to the center.
  • Altitude: higher elevations often need longer roasting at the same temperature.
  • Open roasting vs covered: foil traps steam and slows browning but speeds the center.

Check the turkey 45 minutes before your estimated finish time. If it is already close, you avoid overcooking. If it is far off, you know to keep waiting.

Step By Step Roasting Plan

  1. Thaw the turkey in the fridge, allowing 24 hours for every 4 to 5 pounds.
  2. Preheat the oven to 325°F and set a rack in the lower third.
  3. Pat the bird dry, season inside and out, and place it breast up in a roasting pan.
  4. Calculate your time using 15 minutes per pound as a baseline.
  5. Start checking the internal temperature 45 minutes before the estimate.
  6. Pull the turkey at 165°F in the thigh and breast.
  7. Rest for 20 to 30 minutes, tented loosely with foil, then carve.

Write your start time on a sticky note and set a timer for the early check. This one habit prevents both dry meat and a late dinner.

Common Mistakes To Avoid

  • Relying only on pop up timers, which often trigger late or early.
  • Opening the oven door every 20 minutes, which drops the temperature.
  • Stuffing the bird the night before, which invites bacteria growth.
  • Skipping the rest, which lets juices run out onto the cutting board.
  • Cooking to a fixed time instead of a fixed temperature.

Follow the weight chart, trust your thermometer, and give the bird a proper rest. Your turkey will come out safe, moist, and ready to serve.
