as far as baking goes, you can generally cook things about the same time as usual by using a larger pan so that the depth
of what's being cooked is the same as usual. if you don't have a large enough pan to do so, try using two pans or more. while you don't want to be moving cakes around during baking, casseroles can be move from top to bottom rack from time to time for even cooking.
