Special Instructions for quantity cookery

When you’re cooking this much chicken, it’s much easier to bake it in the oven rather than splatter up your range. In which case you’ll need some roasting pans. About an hour in a preheated 350° is good; maybe an hour and a half if your trays are densely packed.
