Cooking a 10 kg turkey
The usual rule is 20 minutes a kilo, plus 90 minutes for a turkey of this size, at 180°C (160°C fan), which gives 4 h 50 min for 10 kg. Weigh the turkey after stuffing it and always check the label, because pack timings differ.
What time to put it in the oven
Work back from when you want to carve: cooking time, then 45 minutes of resting under foil. Add time for the oven to heat up, and the roast potatoes go in the hot oven while the turkey rests.
| To carve at | Put the turkey in at |
|---|---|
| 1:00 pm | 7:25 am |
| 2:00 pm | 8:25 am |
| 3:00 pm | 9:25 am |
| 4:00 pm | 10:25 am |
Thawing a 10 kg turkey
Allow about 5 days in the fridge: 10 to 12 hours a kilo, so 120 hours at the long end. Start early, and never thaw a turkey at room temperature.
