A 15-pound turkey at 350°F usually roasts for 3 to 3¾ hours unstuffed, or about 3¾ to 4¼ hours stuffed.
A roast turkey can feel like a high-wire act. Pull it early and the center is underdone. Leave it too long and the breast turns chalky.
If your oven is set to 350°F, the usual range for a thawed 15-pound turkey is about 3 to 3¾ hours if it’s unstuffed. A stuffed bird needs more time, usually 3¾ to 4¼ hours. That range gets you close. The finish line is temperature, not the timer. Roast until the thickest part of the breast, the thigh, and the wing joint all hit 165°F.
How Long To Cook a 15 Lb Turkey at 350 With Better Accuracy
Start with the broad answer, then tighten it up with the details of your bird. For a plain, thawed, unstuffed 15-pound turkey, check it at the 3-hour mark. If you packed stuffing inside the cavity, start checking closer to 3¾ hours. Opening the oven every 15 minutes is a trap, so resist the urge. Each peek dumps heat and stretches the roast.
These are the timing lanes most home cooks use at 350°F:
- Unstuffed: 3 to 3¾ hours
- Stuffed: 3¾ to 4¼ hours
- Resting time after roasting: 30 to 45 minutes
Resting matters as much as oven time. It lets the juices settle back into the meat, so the slices stay moist instead of flooding the cutting board.
What Changes The Roasting Time
Turkey timing isn’t one-size-fits-all. A bird pulled straight from the fridge will cook a bit faster than one with a still-chilly center. A dark roasting pan can brown the skin faster. A crowded oven can slow things down. So can a thick layer of glaze brushed on too early.
Here are the biggest factors that nudge the time up or down:
- Stuffing: A packed cavity slows heat flow.
- Starting temperature: A fully thawed bird roasts more evenly.
- Pan depth: A shallow pan lets hot air move better.
- Frequent door opening: Heat drops fast every time the door swings open.
- Foil cover: Foil can slow browning on the breast, which is handy if the skin darkens too soon.
If you want cleaner timing, roast the stuffing in a separate dish. You’ll get a crisper top, a safer cook, and less guesswork from the clock.
Timing Chart For A 15-Pound Bird And Nearby Sizes
Turkey math gets easier when you can see where your bird sits in the wider range. This table gives you a practical 350°F view for whole turkeys, plus the point where you should start checking temperature.
| Turkey Size | Unstuffed At 350°F | Stuffed At 350°F |
|---|---|---|
| 10 lb | 2 to 2¾ hours | 2¾ to 3¼ hours |
| 11 lb | 2¼ to 3 hours | 3 to 3½ hours |
| 12 lb | 2½ to 3 hours | 3 to 3½ hours |
| 13 lb | 2¾ to 3¼ hours | 3¼ to 3¾ hours |
| 14 lb | 3 to 3½ hours | 3½ to 4 hours |
| 15 lb | 3 to 3¾ hours | 3¾ to 4¼ hours |
| 16 lb | 3¼ to 4 hours | 4 to 4½ hours |
| 17 lb | 3½ to 4 hours | 4 to 4½ hours |
Use that chart as your map, then verify with a thermometer. That step is non-negotiable. The USDA’s turkey roasting advice and the safe minimum internal temperature chart both point to 165°F for poultry.
How To Roast It So The Meat Stays Juicy
A good turkey is more than a number on a timer. The oven setup, the pan, and the way you season the bird all shape the result. A few simple moves do most of the work.
Before The Bird Goes In
- Pat the turkey dry with paper towels. Dry skin browns better.
- Rub the skin with butter or oil. Then season the outside and cavity.
- Tuck the wing tips behind the bird so they don’t burn.
- Set the turkey breast-side up on a rack in a shallow pan.
- Add a cup or two of water or broth to the bottom if you want drippings that are less likely to scorch.
If your turkey is frozen, thawing can take longer than new cooks expect. The USDA’s safe thawing advice gives the refrigerator rule at about 24 hours for each 4 to 5 pounds, so a 15-pound bird usually needs 3 to 4 days in the fridge.
During The Roast
Set the pan on a lower-middle rack so hot air can move around the bird. Roast at 350°F. After about 90 minutes, take a look at the skin. If the breast is getting too dark, lay a loose foil tent over it. Don’t wrap it tight. You want to slow browning, not steam the skin.
Basting is optional. It can add color, though it won’t drive moisture deep into the meat. If you baste, do it once or twice near the end. Repeated basting drags out the cooking time by cooling the bird and opening the oven.
Foil And Browning
If the skin is browning too fast while the inside still needs time, lay a loose foil tent over the breast. That slows the color change without trapping too much steam.
Where To Check Temperature
This is the part that saves dinner. Insert the thermometer into the thickest part of the thigh without touching bone. Then check the thickest part of the breast and the inner wing area. If you stuffed the cavity, the center of the stuffing should also hit 165°F.
Don’t trust the pop-up timer by itself. It can lag behind the real doneness point, and it only checks one area. A fast digital thermometer gives you a far cleaner read.
| Spot To Check | Target Temperature | Why It Matters |
|---|---|---|
| Breast | 165°F | Prevents dry white meat from overshooting while you wait on the thigh |
| Thigh | 165°F | Dark meat cooks slower and is often the last section to finish |
| Wing Joint Area | 165°F | Catches cool spots near the bone |
| Stuffing | 165°F | Stops undercooked filling in the center of the bird |
Common Timing Mistakes That Ruin Turkey
Most turkey trouble comes from a handful of habits. Fix those and the roast gets much easier.
- Cooking by pounds alone: Weight gives you a range, not a promise.
- Starting with a partly frozen center: The outside dries out while the middle catches up.
- Stuffing too tightly: Dense stuffing slows the cook and can leave cold pockets.
- Skipping the rest: Carving too soon sends the juices running.
- Relying on color: Golden skin looks done long before the center is ready.
One more trap: carving straight from the oven because the bird “looks done.” Give it 30 to 45 minutes on the counter, loosely tented with foil. That pause makes cleaner slices and buys you time to finish gravy, warm sides, or bring the table together.
If Your Turkey Is Done Early
Done early is a nice problem to have. Leave the bird whole, tent it loosely with foil, and let it rest. A big turkey holds heat well while the last dishes finish up.
If dinner is still a ways off, carve the turkey, arrange the slices in a baking dish with a little warm stock, and cover it. That keeps the meat from drying out while you wait. Don’t let cooked turkey sit out for more than 2 hours.
Carving And Serving A 15-Pound Turkey
A 15-pound turkey usually feeds about 10 to 12 people with a fair shot at leftovers, depending on how many sides are on the table. For neater slices, remove the legs first, then the wings, then cut each breast lobe off the bone before slicing across the grain.
If leftovers are part of the plan, get the meat off the carcass not long after the meal. It cools faster in shallow containers than in one giant bowl. That means better texture the next day and less scrambling after everyone leaves.
So, how long should you cook a 15-pound turkey at 350°F? Plan on 3 to 3¾ hours for an unstuffed bird, or 3¾ to 4¼ hours for a stuffed one. Start checking before the end of the range, trust the thermometer over the clock, and let the turkey rest before carving. That’s the combo that gives you crisp skin, juicy slices, and no last-minute panic.
