- Unstuffed. A stuffed bird needs 30–60 extra minutes; check stuffing separately.
- Times assume the food starts refrigerated, not room temperature.
Whole turkey cooking time by size
| Size | Approximate | Time |
|---|---|---|
| Small (4.5 kg) | ≈4.5 kg, serves 8–10 | 2 hr 47 min – 3 hr 17 min |
| Medium (6 kg) | ≈6 kg, serves 12–14 | 2 hr 47 min – 3 hr 17 min |

Fresh vs frozen
Cooking from frozen takes roughly 50% longer and cooks less evenly. These estimates are for a medium (6 kg).
Fresh / refrigerated
2 hr 47 min – 3 hr 17 min
From frozen
4 hr 11 min – 4 hr 55 min
USDA guidance allows frozen poultry and meat to be cooked without thawing; allow extra time and never thaw at room temperature.
How to know when it's done
Time is an estimate — temperature is the truth. Check the thickest part with an instant-read thermometer: whole turkey is safely done at 165°F / 74°C.

Frequently asked questions
How long does a 6 kg turkey take?
Roughly 3 hours at 190°C plus a 30-minute rest. Start checking the internal temperature an hour early — ovens vary a lot.
Should I cover the turkey with foil?
Cover the breast with foil for the first two-thirds of cooking, then uncover to brown. Rest 30 minutes loosely tented.
