If a recipe calls for a 2.5 quart casserole dish, does it matter what shape it is? I have only been out of the parents house and a dorm room for a few years and so I seem to have only acquired a very deep round casserole dish. I plan to make a few holiday side dishes for an office party (sweet potato casserole, macaroni and cheese) and my only experience is from my mother and grandmother who seemed to usually bake the dishes in rectangular shallow casserole dishes. Does the shape matter? Should I go on the hunt or swipe one of theirs to make the dishes?
