I will be cooking for approximately 100 people for a church Thanksgiving dinner. How many 18 to 20 pound turkeys will I need to feed that many people???
I think you will need at least 15 turkeys. 10 Turkeys should feed 100 people, but 15 will leave room for leftovers. People love to take an extra plate home.
Consider a serving 1 pound per person. 5 20lb. turkeys should work for 100 people.
I would do a minimum of three.
Figure 1.5lbs per person
Ah, my we all have such different answers. When I was cooking in an institutional kitchen, we always planned 1/2 of turkey per person. That was 1/2 pound of the uncooked turkey. It feed folks very generously.
Additionally, I would think that you would need to take into consideration the other items being served. If there is ham in addition to the turkey, you need less turkey. How many sided dishes are being served?
Also, are you plating the meals or is this a buffet. Plating, you can be more exact with quantities. Buffet, I always tend to error on the high side.
If you are serving a buffet, if the Turkey is that the beginning of the line, you will need more turkey, than if it is the last item.
Finally, what is the age of the people being served. If they are fifty and over 1/2 pound per person is probably reasonable. If they are mostly 12 to 35, then I would allow for 1 pound per person.
