Part of the project planner: Planning the holidays: dinner, tree and lights.

Plan on 1 to 1½ pounds of turkey per person, because a whole bird is about half bone. For 10 adults and 2 children that is a 17 lb turkey, which needs 5 days to thaw in the refrigerator and roasts for 3 h 45 min to 4 h 15 min at 325°F. The charts show every size from 4 to 20 guests.

Turkey size by number of guests

Pounds to buy at four amounts per person (1 lb is the USDA minimum; 1½ lb leaves some leftovers; 2 lb leaves plenty):

Guests1 lb each1¼ lb each1½ lb each2 lb each

Count children as half. For more than 20 pounds consider two smaller turkeys, which cook faster and more evenly. For 4 or fewer people a bone-in turkey breast is simpler. Use the turkey size calculator for your own table.

Thawing and roasting times

Thawing in the refrigerator takes 24 hours for every 4 to 5 pounds; we round up. In cold water it takes 30 minutes a pound. Roasting times are for an unstuffed turkey at 325°F:

If you run behind, switch to the cold-water method, which is much faster but needs attention, and cook the turkey straight afterward.

Safe thawing and cooking

  • Never thaw a turkey on the counter. The outside reaches unsafe temperatures while the middle is still frozen.
  • Keep it cold. The refrigerator should be at 40°F or below, and a drip tray on the bottom shelf stops raw juices touching other food.
  • Cook to 165°F in the thickest part of the breast and thigh, and in the center of any stuffing. Color is not a reliable guide.
  • Do not wash the turkey. It spreads bacteria. Pat it dry with paper towels instead.
  • Refrigerate leftovers within 2 hours, and eat them within 3 to 4 days.

Mistakes that cost people their dinner

  • Starting the thaw too late. A big turkey takes four or five days in the refrigerator.
  • Buying by price per pound alone: a very big bird may not fit in your oven or your roasting pan.
  • Roasting by the clock and not by the thermometer. Ovens and birds differ.
  • Carving at once, rather than resting the turkey for 20 to 30 minutes.
