## Turkey cooking times by weight

### UK times

UK guidance from British Turkey: roast at 190°C (170°C fan), 375°F for **20 minutes per kg, plus 70 minutes for a turkey under 4 kg or 90 minutes for one of 4 kg or more**. Weigh the bird with any stuffing in it.

Whole turkey at 190°C (170°C fan), 375°F:

| Weight | Cooking time | Rest at least |
| --- | --- | --- |
| 3 kg (6.6 lb) | 2 h 10 min | 30 min |
| 4 kg (8.8 lb) | 2 h 50 min | 30 min |
| 5 kg (11 lb) | 3 h 10 min | 45 min |
| 6 kg (13.2 lb) | 3 h 30 min | 45 min |
| 7 kg (15.4 lb) | 3 h 50 min | 45 min |
| 8 kg (17.6 lb) | 4 h 10 min | 45 min |
| 9 kg (19.8 lb) | 4 h 30 min | 45 min |
| 10 kg (22 lb) | 4 h 50 min | 45 min |

### US times

US guidance from the USDA: roast at 325°F (165°C). A stuffed bird takes longer, because the stuffing must reach 165°F too.

Whole turkey at 325°F (165°C):

| Weight | Unstuffed | Stuffed | Rest at least |
| --- | --- | --- | --- |
| 8 lb (3.6 kg) | 2 h 45–3 h | 3 h–3 h 30 min | 30 min |
| 10 lb (4.5 kg) | 2 h 45–3 h | 3 h–3 h 30 min | 30 min |
| 12 lb (5.4 kg) | 2 h 45–3 h | 3 h–3 h 30 min | 45 min |
| 14 lb (6.4 kg) | 3 h–3 h 45 min | 3 h 30–4 h | 45 min |
| 16 lb (7.3 kg) | 3 h 45–4 h 15 min | 4 h–4 h 15 min | 45 min |
| 18 lb (8.2 kg) | 3 h 45–4 h 15 min | 4 h–4 h 15 min | 45 min |
| 20 lb (9.1 kg) | 4 h 15–4 h 30 min | 4 h 15–4 h 45 min | 45 min |
| 22 lb (10 kg) | 4 h 30–5 h | 4 h 45–5 h 15 min | 45 min |
| 24 lb (10.9 kg) | 4 h 30–5 h | 4 h 45–5 h 15 min | 45 min |

## How to tell your turkey is cooked

Push a meat thermometer into the thickest part of the thigh, without touching the bone. It’s done at **74°C (165°F)**. Without a thermometer, pierce the thigh with a skewer: the juices should run clear, with no pink, and the leg should feel loose.

## Resting

Lift the turkey onto a board, cover it loosely with foil and a couple of tea towels, and leave it for at least 30 minutes. A large bird stays hot for well over an hour, which frees the oven for roast potatoes and the rest of the sides.

## Questions

### How long does a 5 kg turkey take to cook?

About 3 h 10 min at 190°C (170°C fan), then at least 30 minutes to rest.

### How long does a 14 lb turkey take?

At 325°F, 3 h to 3 h 45 min unstuffed, or 3 h 30 min to 4 h stuffed.

### Should I cover the turkey with foil?

Cover it loosely for most of the cooking so the breast doesn’t dry out, then take the foil off for the last 45 minutes to brown the skin.

### What temperature should a turkey be when it’s cooked?

At least 74°C (165°F) in the thickest part of the thigh.

### How long should a turkey rest?

At least 30 minutes, and up to 90 for a big bird, covered loosely with foil.
