A roasting pan is a piece of cookware used for roasting meat in an oven, either with or without vegetables or other ingredients. A roasting pan may be used with a rack that sits inside the pan and lets the meat sit above the fat and juice drippings. A shallow roasting pan is normally used for roasting small cuts of meat, but large-size roasting pans are also used for cooking large poultry such as turkey or goose, or for larger cuts of meat.
Roast may use a combination of bottom and top, or bottom and convection. With baking, such as bread and cakes, you want an even heat, which typically is produced by letting heat rise from the bottom. Roasting, such as when cooking a roast or chicken, shifts the heat balance toward the top - browning the top of the meat as is as important, if not more so, than the bottom.
