Turkey Cooking Time Calculator
The one day of the year this matters most. Let us nail it.
Turkey is the meat most people cook once or twice a year, which is exactly why people mess it up. We do not build muscle memory for it. This calculator takes the guesswork out.
Enter your turkey's weight, choose whether it is stuffed or unstuffed, pick your oven temperature (most recipes use 325F, but variations exist), and get the total cooking time plus milestones. When to check, when to tent with foil to prevent over-browning, and when to test internal temperature.
The calculator follows USDA-recommended guidelines (165F internal temp at the thickest part of the thigh, measured away from bone) and accounts for the significant cooking-time difference between stuffed and unstuffed birds. Stuffed takes 30-50 minutes longer because the stuffing must also reach 165F.

USDA Reference Times (at 325F)
Standard roasting times for unstuffed turkey.
| Weight | Time |
|---|---|
| 4-6 lb unstuffed | 1h 30m - 2h 15m |
| 6-8 lb unstuffed | 2h 15m - 3h 15m |
| 8-12 lb unstuffed | 2h 45m - 3h |
| 12-14 lb unstuffed | 3h - 3h 45m |
| 14-18 lb unstuffed | 3h 45m - 4h 15m |
| 18-20 lb unstuffed | 4h 15m - 4h 30m |
| 20-24 lb unstuffed | 4h 30m - 5h |
| Stuffed (any size) | Add 30-45 min to above |

The Reference
USDA-recommended safe turkey internal temperature: 165F (74C) at the thickest part of the thigh and in the stuffing center. Most turkey failures come from overcooking the breast (which reaches 165F faster than the thigh) while waiting for the thigh to hit temp.
Tenting the breast with foil after the first hour protects it. Removing the turkey at 160-162F and resting allows carryover cooking to hit the target without over-drying. Rest 20-30 minutes before carving. Essential, not optional.
The Carryover Problem in Large Roasts
A 15-pound turkey has massive thermal mass. When you pull it from the oven, the internal temperature continues rising for 20-30 minutes as heat conducts from the outer layers toward the center. Pulling a turkey at 165F means serving it at 170-175F in the thickest parts, which is dry.
Professional turkey technique: pull the bird when the thigh (thickest muscle, measured near the joint but not touching bone) reaches 160-162F. Cover loosely with foil. Rest 20-30 minutes. The temperature will coast to 165-170F, the USDA safe target, while the fibers relax and redistribute juices. The result is dramatically juicier than a turkey cooked to 170F in the oven.
For stuffed turkeys, the stuffing itself must reach 165F for food safety. This typically happens 20-30 minutes after the turkey meat does, which is why stuffed birds often overcook. Many cooks now bake stuffing separately, using pan drippings for flavor. This is the approach recommended by most food safety experts and professional chefs.
How to Use
- Enter your turkey's weight in pounds (post-thaw).
- Specify stuffed or unstuffed.
- Choose oven temperature. 325F is the standard.
- Get total time, tent timing, and target temperature. Use a thermometer to verify.
Frequently Asked Questions
Should I cook turkey stuffed or unstuffed?
Food safety experts recommend unstuffed. The stuffing must reach 165F, which often means overcooking the turkey. If you want stuffing flavor, cook the stuffing separately in the pan drippings or bake it in a casserole. Many chefs consider this the superior approach both for safety and texture.
How long does a 15 lb turkey take to cook?
Approximately 3h 45m to 4h at 325F, unstuffed. Plus 20-30 minutes rest. Add 30-45 minutes if stuffed.
Why does my turkey come out dry?
Three common causes: cooking past 165F in the breast, not resting before carving, not brining or covering with butter or oil. Solutions: use a thermometer and pull at 160-162F; rest 20-30 minutes; brine for 12-24 hours before cooking, or rub butter under the skin before roasting.
Is brining worth it?
Yes, for 12-24 hours. A wet brine (salt plus water plus aromatics) or dry brine (salt rubbed on and refrigerated uncovered) significantly improves moisture retention. Dry brining is simpler and arguably produces crispier skin.
What if my turkey is still partially frozen?
Thaw in cold water: 30 minutes per pound, changing water every 30 minutes. A 15 lb turkey takes about 7.5 hours in cold water. Never thaw at room temperature (food safety). Cooking a fully frozen turkey is possible but takes 50% longer and cooks unevenly.
How much turkey per person?
1 pound per person if you want leftovers. 0.75 pound per person for just-the-meal servings. A 15 lb turkey serves 10-12 people comfortably with leftovers, or 15-18 without.
When should I take the turkey out of the fridge?
1-2 hours before roasting. Room-temperature turkey cooks more evenly. Do not leave it out longer than 2 hours (food safety).
