How much turkey per person?
The standard rule is 1 pound of uncooked whole turkey per adult and 0.5 pounds per child. This accounts for the weight lost to bones, skin, and fat during cooking. A typical whole turkey yields roughly 40-50% edible meat after cooking, so a 16-pound bird produces about 7-8 pounds of usable meat. If you want generous leftovers for sandwiches and soup, increase the per-person allowance by 50%. For groups smaller than 8, add a bone-ratio buffer because small birds have more bone relative to meat. Very large groups of 20 or more guests are better served by two 12-14 lb birds than one oversized turkey, which cooks more evenly and is easier to handle.
Cooking times by method
Oven roasting at 325 F is the most common method, taking about 13 minutes per pound for an unstuffed bird and 17 minutes per pound for a stuffed one. A 14-pound unstuffed turkey takes roughly 3 hours. Smokers running at 225-250 F produce deeply flavored, juicy results but need about 30 minutes per pound, so a 14-pound bird requires around 7 hours. Deep frying at 350 F oil temperature is the fastest option at 3-4 minutes per pound, so the same 14-pound turkey takes only about 50 minutes, and produces exceptionally crispy skin. Grilling with indirect heat mirrors oven times. Always verify the thickest part of the breast and thigh reach 165 F on a meat thermometer before serving, regardless of method. After cooking, rest the bird 30-45 minutes tented with foil. The internal temperature will continue to rise 5-10 degrees during the rest.
How to thaw a frozen turkey safely
The two USDA-approved methods for thawing a whole turkey are refrigerator thawing and cold-water thawing. In the refrigerator at 40 F or below, allow approximately 24 hours for every 4-5 pounds of turkey. A 16-pound bird takes 3-4 days. Place it breast-side up on a tray to catch drips and keep it in the original wrapping. Once thawed it is safe in the refrigerator for 1-2 days before cooking. For cold-water thawing, keep the turkey in its original leak-proof packaging and submerge it in cold water. Change the water every 30 minutes to maintain safe temperatures. Allow 30 minutes per pound, so a 16-pound bird takes 8 hours. Cook immediately after the cold-water thaw is complete. Never thaw a turkey on the countertop at room temperature, as the outer layers enter the danger zone (40-140 F) long before the center is safe.
Brining, seasoning, and prep tips
Brining adds moisture and flavor that compensates for the long cooking time. A simple dry brine of 1-1.5% of the turkey weight in kosher salt (about 1 tablespoon per 4-5 lb), applied 24-48 hours before cooking and left uncovered in the refrigerator, is one of the most effective ways to improve a roast turkey. Wet brining (roughly 1 cup of kosher salt per gallon of water) works in 12-18 hours but requires space for a large container. Rinse and thoroughly pat dry after a wet brine to promote browning. For crispy skin, let the turkey air-dry uncovered in the refrigerator overnight after seasoning. Stuff the turkey only if cooking in a conventional oven, and pack the stuffing loosely. The USDA recommends baking stuffing separately to 165 F for best food safety. Spatchcocking (removing the backbone and pressing flat) reduces oven time by 30-40% and gives more evenly cooked, crispier results.

| 10 | 10-12 | 15-18 | Step up to a 14-16 lb bird |
| 12 | 12-14 | 18-21 | 14-16 lb bird or two smaller birds |
| 16 | 16-18 | 24-27 | Two 12-14 lb birds recommended |

Approximate turkey weight needed at 1 lb per adult, 0.5 lb per child. Add 50% for generous leftovers.
Frequently asked questions
How much turkey do I need per person?
Plan on 1 pound of uncooked whole turkey per adult and 0.5 pounds per child. Because bones, skin, and fat account for roughly half the total weight, this yields about 0.5 pounds of edible meat per adult, which is a generous serving. If you want leftovers, increase the per-person allocation by 50%.
How long does it take to cook a turkey?
In a conventional oven at 325 F, an unstuffed turkey takes about 13 minutes per pound and a stuffed turkey takes about 17 minutes per pound. A 14-pound unstuffed bird takes roughly 3 hours. Smokers at 225-250 F need about 30 minutes per pound. Deep fryers at 350 F oil temperature take only 3-4 minutes per pound. Always confirm 165 F internal temperature with a meat thermometer regardless of the estimated time.
How long does it take to thaw a frozen turkey?
Refrigerator thawing (the safest method) takes about 24 hours for every 4-5 pounds - so a 16-pound turkey needs 3-4 days. Cold-water thawing is faster at about 30 minutes per pound, but you must submerge the turkey in cold water, change the water every 30 minutes, and cook immediately afterward. Never thaw on the counter.
Should I stuff the turkey or cook dressing on the side?
The USDA recommends cooking stuffing separately for food safety. When you stuff a turkey, the stuffing must also reach 165 F, which requires longer cooking that can dry out the breast meat. Cooking dressing in a separate dish gives you more control, safer temperatures, and crispier turkey skin. If you prefer a stuffed turkey, use a food thermometer to verify both the deepest part of the stuffing and the thickest part of the thigh reach 165 F.
Is it better to cook two small turkeys instead of one large one?
For groups of 20 or more, two 12-14 lb turkeys are usually better than one very large bird. Large turkeys (over 20 lb) take much longer to cook, are harder to maneuver, and tend to cook unevenly - the breast often dries out before the thigh reaches temperature. Two smaller birds cook faster, more evenly, and fit standard oven racks more easily.
How long should I rest the turkey after cooking?
Rest the turkey for 30-45 minutes after removing it from heat, tented loosely with foil. The internal temperature will continue to rise 5-10 degrees (carryover cooking), and resting allows the juices to redistribute through the meat, making carving easier and the meat noticeably juicier. Do not skip the rest.
What temperature should the turkey reach?
The USDA safe minimum internal temperature for turkey is 165 F (74 C), measured in the thickest part of the breast (without touching bone), the thickest part of the thigh, and the center of the stuffing if stuffed. Check all three spots before declaring the bird done. A high-quality instant-read thermometer is the most reliable way to verify this.
