Turkey roasting tips

  • Follow the cooking instructions on the pack. Use the calculator time and oven setting to plan. A timer alone cannot tell you when turkey is safe to serve.
  • For an unstuffed whole bird without pack instructions, the Food Standards Agency uses a preheated oven at 180°C conventional or 160°C fan (Gas Mark 4). Under 4.5 kg, allow 45 minutes per kg plus 20 minutes. From 4.5 to 6.5 kg, allow 40 minutes per kg. Over 6.5 kg, allow 35 minutes per kg. For a crown without instructions, ask the retailer for guidance.
  • Cook stuffing in a separate roasting tin.
  • Cook turkey all the way through. Use a clean thermometer in the thickest part, away from bone. On a whole bird, check between the breast and leg. Make sure the meat stays at or above 75°C for 30 seconds or 70°C for 2 minutes.
  • Without a thermometer, cut into the thickest part. The meat should be steaming hot throughout with no pink meat and clear juices.
  • Allow time for the turkey to rest before carving.
