How to Convert Oven Recipes to Air Fryer
Choosing the right turkey size ensures everyone gets fed with enough for sandwiches the next day. The calculation is based on per-person serving weight.
The basic rule:
- Bone-in whole turkey: 1 to 1.5 lbs per person
- Boneless turkey breast: 0.5 to 0.75 lbs per person
- Thawing: 24 hours per 4-5 lbs in the refrigerator
Add about 25% more weight if you want generous leftovers. Cooking time at 325°F is approximately 13-15 minutes per pound for an unstuffed turkey. Always use a meat thermometer — the turkey is done when the thickest part of the thigh reaches 165°F.

Frequently Asked Questions
How many pounds of turkey per person?
For a whole bone-in turkey, plan for 1 to 1.5 pounds per person. For boneless turkey breast, plan for 0.5 to 0.75 pounds per person. The bone and carcass account for about 40% of a whole turkey's weight, which is why you need more per person.
How long does it take to thaw a turkey?
In the refrigerator, allow 24 hours for every 4-5 pounds. A 16-pound turkey takes about 3-4 days. For faster thawing, submerge in cold water and change the water every 30 minutes — this takes about 30 minutes per pound.
How long to cook a turkey at 325°F?
For an unstuffed turkey at 325°F: 8-12 lbs takes 2.75-3 hours, 12-14 lbs takes 3-3.75 hours, 14-18 lbs takes 3.75-4.25 hours, 18-20 lbs takes 4.25-4.5 hours, 20-24 lbs takes 4.5-5 hours. Always verify with a meat thermometer (165°F in the thigh).
What if my turkey is too big for one bird?
If you need more than 22-24 pounds, buy two smaller turkeys instead. Two 12-pound turkeys cook faster and more evenly than one 24-pound turkey. They also thaw faster and fit in the oven more easily.
Should I buy a fresh or frozen turkey?
Both taste great. Frozen turkeys are more affordable and can be bought well in advance. Fresh turkeys don't require thawing time but should be purchased 1-2 days before cooking. Fresh turkeys may have slightly better texture but the difference is subtle.
How much turkey for leftovers?
Add about 25-30% more turkey weight if you want leftovers. For example, if you need 15 lbs for your guests, buy an 18-20 lb turkey. This gives enough for turkey sandwiches, turkey soup, and other leftover meals for 2-3 days.
