These are guides: ovens vary, so check your turkey's label and use a probe thermometer. Always thaw a turkey fully in the fridge, wash your hands and surfaces after handling raw meat, and do not wash the bird. Cook a stuffed turkey for the time on the pack, which is based on the weight of the bird and the stuffing separately.

Before you buy: round up to whole packs, check the size printed on the label, and add a little spare. Your supplier has the final say.

Cooking a 7 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 3 h 50 min for 7 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.
