How much turkey should I plan per person?

Unless you're feeding 20, chances are you want the smallest bird they have. It doesn't really matter if you should have 1 lb per person or 1.5 if you have 8 people and their smallest bird is 12 pounds - and I'm willing to bet that's the case.

That said, I generally allow 1 lb per person and don't count the smallest children (say, haven't started school yet.) I also tend to send a lot of leftovers home with other people. Our feasts are very veggie heavy, but as I mentioned above you may have less control over this than you think.

Typically for any whole animal (turkey, pig, or chicken) cooked for a holiday feast I plan for 1lb (dressed weight) per person. If there are going to be a lot of children, you can revise that down a half lb for each child under 12. In my experience this formula usually ends up with enough leftovers for people to take some home, but not so many that you're stuck eating turkey for 3 weeks.

For example, last week I cooked a 5 lb turkey breast for 5 people, after dinner there was approx 1.25 lbs leftover, which is easily enough for 3-4 sandwiches or a pot pie. Keep in mind that this meal did not include a lot of heavy side dishes, so it yielded a few less leftovers than a typical holiday dinner would using the same formula.

Butterball's planning calculator suggests 1.5 lbs per adult and 1 lb per child if you want to be sure to have leftovers and are "light eaters". I think that's probably overkill and/or their way to sell 50% more turkey... especially if you plan on having 3 or more side dishes.

I work in a deli and over the holidays we cook and debone a lot of turkeys. I can tell you from experience that a 20# turkey will yield about 8-10 pounds of meat. This is because when the turkey cooks it releases a surprising amount of liquid. Add in all the bones and you loose a lot of your starting weight. So you really do want to figure 1 1/2 to 2 pounds per person, especially if you want leftovers.

We found a 7lb turkey which, for the three of us, gave almost no leftovers. So clearly the 1-lb per person measure breaks down at sufficiently small numbers of people :(

At Serious Eats, Kenji Lopez Alt says:

As a general rule, larger birds will have plumper breasts (a higher meat to bone ratio), so you'll want to use a little bit less turkey per person by weight. [...] if you're the type who likes leftovers (I do). I'd aim for 3/4 pounds of live weight per person to be safe.

This is in line with my own experiences. It matches the Butterball recommendation for Turkey Breast, as well, although they don't seem to post on their main website a recommended estimate for whole turkeys.

I think if you have a 3 to 4 adults, a 3-pound boneless turkey, plus 1 or 2 drumsticks alongside the breast is a VERY ample amount of meat....and some leftover too!

• You should first know how many people you are inviting for the Thanksgiving, are they five or ten people, are there three or six children. Secondly how are you going to prepare the events; are you going to cook a variety of food such that your guest will have turkey, pumpkin, potatoes, bread, pie, drinks, dessert etc.
• If you will prepare that many variety, then the guest will likely try all of them, meaning they will just eat enough of turkey, pumpkin, potatoes etc.
• Turkey will probably be the special part of the Thanksgiving. Many people especially with their family and friends in mind, would normally prepares one full turkey. I suggest you buy one big turkey for this event also considering how many guest you will invite. Also cook it well enough so that people will be satisfied with the turkey even before they get to eat it.
