Substitute chicken breasts for whole chickens

[muzzlet]

I have a casserole recipe calling for a 5 pound chicken, to be poached with vegetables and then cut up and mixed with the rest of the ingredients.

My question: how much boneless, skinless chicken breast would equal the same amount of meat from a 5 pound whole chicken? I know the whole weight is not edible meat. Frankly, I'm just too darned lazy to cook the whole chicken, and nobody in my family likes dark meat anyway. Yes, I know dark meat is more flavorful, but ...

Thanks!!

I'd use 6 boneless breasts. 1 to take place of each main part of a whole chicken. 2 legs, 2 thighs, 2 breasts. Maybe 1 more for the wings?

Edit: Maybe just 5.

Just do a half breast for each person.

Not including gibblets, one whole chicken will yield you roughly half it's original mass once it's broken down.

Of course you won't have all of that wonderful poaching liquor.

I think roasting a whole chicken is easier than cooking 6 breasts.
