Estimated cooking time: 165–225 minExamples
Use the USDA weight-class range at 325 °F. An 8 lb stuffed whole turkey needs roughly 180–210 minutes; plan enough time and confirm 165 °F in breast, thigh and stuffing with a thermometer.

USDA weight-class range at 325 °F
- StepEnter the weight of the whole bird in pounds; the packaging usually prints it.Turkey weight (lb)=12lb
- StepChoose stuffed or unstuffed and keep the oven at 325 °F.Stuffed or unstuffed?=Unstuffed
- StepAllow the upper end of the displayed range for planning; boundary weights include both adjacent classes.
- ResultStart probing 45 minutes early: 165 °F in breast, thigh and stuffing is what ends the roast.165–225min
What this number means
The thermometer ends the roast, not the clock
The thickest part of the breast and the innermost thigh must reach 165 °F, and in a stuffed bird the centre of the stuffing has to reach it too. Colour and elapsed time are not a test.
Use a weight-class range
Use the USDA weight-class range at 325 °F. An 8 lb stuffed whole turkey needs roughly 180–210 minutes; plan enough time and confirm 165 °F in breast, thigh and stuffing with a thermometer.
Start probing 45 minutes early
Use the estimate to decide when the bird goes in, never when it comes out. Then allow about 20 minutes of resting before carving.
The field takes pounds, nothing else
The source table is bracketed in pounds. Divide a kilogram figure by 0.4536, so a 5 kg bird is about 11 lb.
Commonly misread
MisconceptionThe timer went off, so the turkey is done.
CorrectionThe time is an estimate; what ends the roast is 165 °F in breast, thigh and stuffing. Measure at the thickest part instead of trusting the clock.
MisconceptionA fixed number of minutes per pound matches the USDA table.
CorrectionThe USDA table gives ranges per weight bracket. A 12 lb unstuffed bird lies on two classes, so this calculator shows their combined range of 165–225 minutes.
MisconceptionStuffing does not change the cooking time.
CorrectionUse the USDA weight-class range at 325 °F. An 8 lb stuffed whole turkey needs roughly 180–210 minutes; plan enough time and confirm 165 °F in breast, thigh and stuffing with a thermometer.
MisconceptionI can carve it straight out of the oven.
CorrectionGive it about 20 minutes so the juices redistribute. Carryover cooking also pushes the internal temperature up a few more degrees while it sits.

Questions
How long do you cook a turkey per pound?
Use the USDA weight-class range at 325 °F. An 8 lb stuffed whole turkey needs roughly 180–210 minutes; plan enough time and confirm 165 °F in breast, thigh and stuffing with a thermometer.
Why do boundary weights have a wider range?
The source classes share endpoints. At 12 lb both the 8–12 lb and 12–14 lb rows apply, so the displayed range includes both rather than choosing the shorter time.
What temperature should turkey reach?
The thickest part of the breast and the innermost thigh must reach 165 °F, or 74 °C. If the bird is stuffed, the centre of the stuffing has to hit 165 °F too. A meat thermometer is the only reliable test — colour and elapsed time are not.
Why does a stuffed turkey take longer?
Use the USDA weight-class range at 325 °F. An 8 lb stuffed whole turkey needs roughly 180–210 minutes; plan enough time and confirm 165 °F in breast, thigh and stuffing with a thermometer.
Can I enter the weight in kilograms?
The field uses pounds to match the source classes. Divide a kilogram figure by 0.4536; a 5 kg bird is about 11 lb. Retain the weight shown on the packaging when it lies close to a class boundary.
Do I need to let the turkey rest?
Yes, give it about 20 minutes before carving. Resting lets the juices redistribute so the meat stays moist, and carryover cooking pushes the internal temperature up a few more degrees while it sits.
