How Long To Cook A 15 Lb Turkey At 350
Cooking a 15 lb turkey at 350°F follows a fairly predictable schedule, though oven calibration and rack position can shift things by 20 minutes or more. If you want to know exactly how long to cook a 15 lb turkey at 350, plan on roughly 3 to 3¾ hours for an unstuffed bird and closer to 4 hours if it’s stuffed.
That range assumes your oven runs true and you keep the turkey on the middle rack. A oven that runs hot can finish the job 20 to 30 minutes early, so always verify with a thermometer instead of trusting the clock alone.
How Long To Cook A 15 Lb Turkey At 350
At 350°F, a 15 pound turkey needs about 13 minutes per pound when unstuffed. That works out to around 3 hours and 15 minutes. Stuffed turkeys need roughly 15 minutes per pound, pushing the total to about 3 hours and 45 minutes.
These times are guidelines, not guarantees. The only reliable test is internal temperature. You want 165°F in the thickest part of the thigh, the breast, and the stuffing if you used any.
Quick Time Chart For A 15 Pound Turkey
- Unstuffed, 350°F: 3 hours to 3 hours 15 minutes
- Stuffed, 350°F: 3 hours 45 minutes to 4 hours
- Convection oven, 325°F: 2 hours 45 minutes to 3 hours
- Foil tent removed last 45 minutes for browning
Notice the convection note. Convection ovens cook faster and browner, so many cooks drop the temp by 25°F and shave 20 to 30 minutes off the total.
Step By Step Cooking Method
- Preheat your oven to 350°F for at least 20 minutes. Don’t skip this. A cold start throws off your timing.
- Pat the turkey dry inside and out with paper towels. Dry skin equals crisp skin.
- Season the cavity and the outside with salt, pepper, and any herbs you like.
- Place the turkey breast side up on a rack inside a roasting pan.
- Add a cup of water or broth to the bottom of the pan to keep drippings from burning.
- Roast uncovered on the middle rack. Baste every 45 minutes if you want, though it’s not required.
- Start checking temperature at the 2 hour 45 minute mark. Don’t wait until the full time is up.
- Pull the turkey when the thigh reads 165°F. Cover loosely with foil and rest 30 minutes before carving.
Why Resting Time Matters
The turkey keeps cooking after it leaves the oven. The internal temp can rise another 5 to 10 degrees during the rest. If you carve right away, the juice runs out and you get dry meat.
Resting for 30 minutes also makes slicing easier. The muscles relax and hold moisture better. Use that time to finish your sides and make gravy from the pan drippings.
Factors That Change Your Cooking Time
Oven Calibration
Many home ovens run 15 to 25 degrees off. An oven set to 350°F might actually be 370°F. That extra heat can cut 20 minutes or more off your cook time. Buy a cheap oven thermometer and check yours once.
Rack Position
The middle rack gives the most even heat. Move the turkey too low and the bottom cooks faster while the top stays pale. Too high and the breast browns before the thighs are done.
Stuffed Versus Unstuffed
Stuffing adds density, which slows heat transfer. A stuffed 15 pound turkey needs about 30 extra minutes. If you stuff loosely and pack it in warm, you save a little time. Never pack stuffing tight.
Pan Size And Material
A dark metal pan absorbs more heat and can speed things up. A shiny pan reflects heat and slows browning. Leave at least 2 inches of space around the turkey so air can circulate.
How To Tell When Your Turkey Is Done
- Thigh temperature: 165°F
- Breast temperature: 165°F
- Stuffing center: 165°F
- Juices run clear when you pierce the thigh
- Legs wiggle freely in their sockets
Check the temperature in two or three spots. A single reading can be misleading if you hit a bone or a pocket of fat. Insert the probe into the thickest meat without touching bone.
Common Mistakes To Avoid
Opening the oven door too often is the big one. Every peek drops the temperature and adds 5 to 10 minutes to your total. Use the oven light instead.
Another mistake is cooking by time alone. A 15 pound turkey from one store can differ from another based on fat content, chill temp, and shape. The thermometer is your friend here.
Don’t tent the turkey with foil for the whole cook either. That steams the skin and you end up with pale, rubbery skin. If the breast browns too fast, lay a small foil shield over just that area.
Final Timing Summary
For a 15 pound unstuffed turkey at 350°F, plan on 3 hours to 3 hours 15 minutes. Add 30 minutes if stuffed. Start checking at 2 hours 45 minutes and rely on a meat thermometer reading 165°F.
Write down your actual start time and finish time. Next time you roast a bird, you’ll have real data from your own oven instead of a generic chart. That’s the best way to nail the timing every year.
