How Long To I Cook A 13 Pound Turkey

ByLily

A 13-pound turkey needs a substantial amount of oven time, and calculating it properly prevents both undercooking and dryness. If you are wondering how long to i cook a 13 pound turkey, the short answer is roughly 3 to 3¾ hours at 325°F, but that number shifts based on whether the bird is stuffed and how your oven actually runs.

This guide breaks down the timing, temperatures, and simple checks so your turkey comes out safe and juicy.

The Short Answer On Cooking Time

At 325°F, a 13-pound unstuffed turkey takes about 3 to 3¼ hours. A stuffed 13-pound turkey needs closer to 3½ to 3¾ hours.

Those times are estimates, not guarantees. Always cook to temperature, not just the clock.

  • Unstuffed 13-pound turkey: 3 to 3¼ hours at 325°F
  • Stuffed 13-pound turkey: 3½ to 3¾ hours at 325°F
  • Target internal temp: 165°F in the thickest part of the thigh

How Long To I Cook A 13 Pound Turkey

Let’s put the full timeline in one place so you can plan your day without guessing. The chart below uses the standard USDA roasting times for a 13-pound bird.

Timing Chart For A 13-Pound Turkey

  • 325°F, unstuffed: 3 to 3¼ hours
  • 325°F, stuffed: 3½ to 3¾ hours
  • 350°F, unstuffed: 2¾ to 3 hours
  • 350°F, stuffed: 3 to 3½ hours

Notice how a 25-degree bump in oven temp can shave off 20 to 30 minutes. Pick one temperature and stick with it for the whole cook.

Why Weight Alone Does Not Tell The Whole Story

Two 13-pound turkeys can finish 40 minutes apart in the same oven. Several things change the math:

  • Stuffed vs unstuffed: stuffing adds 30 to 45 minutes
  • Oven accuracy: many home ovens run 25°F hot or cold
  • Pan material: dark pans brown faster and can speed cooking
  • Starting temp: a fridge-cold bird takes longer than one rested at room temp for 30 minutes
  • Foil tenting: covering the breast slows heat reaching the center

Because of these variables, the internal temperature is the only reliable doneness test.

Step-By-Step Cooking Instructions

Follow these steps in order and you will hit the right doneness window every time.

  1. Preheat your oven to 325°F and set a rack in the lower third.
  2. Pat the turkey dry inside and out with paper towels.
  3. Season the cavity and the skin with salt, pepper, and any herbs you like.
  4. Place the bird breast-side up on a rack inside a roasting pan.
  5. Insert an oven-safe thermometer into the thickest part of the thigh without touching bone.
  6. Roast uncovered for the first 2 hours.
  7. Check the temperature at the 2-hour mark, then every 20 minutes after.
  8. Tent the breast with foil if it browns too fast.
  9. Pull the turkey when the thigh reads 165°F and the breast reads 160°F.
  10. Rest the bird for 20 to 30 minutes before carving.

The rest is not optional. Carryover cooking raises the internal temp another 5 to 10 degrees while the juices redistribute.

How To Tell When Your Turkey Is Done

Use a digital thermometer. Pop-up timers often trigger late, which means dry meat.

Where To Check The Temperature

  • Thigh: the thickest part, away from the bone, should read 165°F
  • Breast: the deepest point should read 160°F
  • Stuffing center: must also reach 165°F

If you check three spots and all hit the target, the bird is safe to eat.

Signs The Turkey Is Not Done Yet

  • Juices run pink or bloody when you pierce the thigh
  • The meat feels springy and resists the thermometer
  • The joint between the thigh and body is still stiff

Put it back in the oven and recheck in 15 minutes.

Tips To Keep A 13-Pound Turkey Moist

Dry turkey usually comes from overcooking, not from bad luck. A few habits keep the meat tender.

  • Brine the bird for 12 to 24 hours before roasting
  • Rub butter or oil under the breast skin
  • Start the oven at 425°F for 30 minutes, then drop to 325°F
  • Do not open the oven door more than needed
  • Let the turkey rest before you slice it

Basting every 30 minutes sounds helpful, but it actually slows cooking by letting heat escape. Skip it or baste just once.

Should You Cook It Covered Or Uncovered

Roast uncovered so the skin crisps. If the top starts to burn, lay a loose foil tent over the breast only. Do not wrap the whole pan, or the bird will steam and the skin will go soft.

Common Mistakes To Avoid

  • Trusting the pop-up timer instead of a thermometer
  • Stuffing the turkey the night before
  • Cooking at 400°F or higher the whole time
  • Slicing immediately after pulling it from the oven
  • Judging doneness by color alone

Each of these mistakes leads to either dry meat or a food safety risk. A thermometer and a 20-minute rest solve most of them.

Final Timing Summary

For a 13-pound turkey at 325°F, plan on 3 to 3¼ hours unstuffed and 3½ to 3¾ hours stuffed. Add 20 to 30 minutes of rest time before carving.

Start checking the internal temperature at the 2½ hour mark. When the thigh hits 165°F, take it out. That single number matters more than any clock or chart, so keep your thermometer close and trust what it tells you.
