How much chicken to purchase?
I'm cooking for a baby shower and I'm making Chicken Parm, Baked Ziti, Meatballs and Sausages for 20 people. How much chicken should I buy for the cutlets? How much pasta, ground beef and sausages?
Since we don't know your recipes, probably the best way to do it would be to look at the number of servings for each recipe and multiply the amount listed for each meat product to come up with 20 servings.
For the cutlets, figure 6 oz. per, though you could go down to four because of the other entrees. So, roughly 7 1/2 lbs chicken. The Ziti and sausage, I'd go five of the (top-quality) ground and another 5-7 of the sausages - will you be slicing them? and figure 4-6 ozs. pasta per person. Enjoy your party.
If you make 20 full portions of everything you will have enough food for 60 people.
Count on 1/2 portions for each person, less if they are light eaters.
With out recipes ,as stated already, and the complete menu giving you quantities is impossible.
Are you serving chips, hors d' ouvres before the meal? I think you should figure on 3/4-1 lb lb of food per person, generally, then figure out how many lbs of each food to apportion. Unless you know your crowd to be big or light eaters... and pre meal bites. I always lean toward making more than enough.
First, baby shower is not usually a corral of heavy eaters. And the food sounds wonderful, but heavy for that gang. So consider that at the most, people will take only a taste of everything. You should cut items down so they can have, for example, 1/3 or 1/2 of a chicken breast HALF, a piece or two of sausage (maybe cut on the ange for 3-4 pieces per link), and either a small meatball, or a half of a larger one, with a single serving spoon of ziti. Do the math from there...
