Turkey Roasting Time Calculator
How long to roast turkey
As a guide, turkey takes about 40 minutes per kilogram, plus around 20 minutes on top, cooked at 180°C (fan 160°C, gas mark 4). Enter your joint's weight above and the calculator does the arithmetic. Cover with foil for most of the cooking and remove near the end to brown. Rest for at least 30 minutes.
Weight-based timings are a starting point, not a guarantee: oven calibration, whether the meat went in fridge-cold, and the shape of the joint all matter. The only reliable test is a meat thermometer in the thickest part, away from bone. Convert your oven dial with the oven temperature and gas mark converter.
