I have been lusting after a Staub roasting pan, and would like to buy one to specifically use for roasting a chicken. I am lost as to the best size of pan to get. They come 9, 11, and 12 inches. When I roast a chicken, it is usually just a chicken, though sometimes I will throw some onion, shallots, carrots or even some potatoes at the bottom of the pot to roast as well.
What size would fit a chicken best?
