Casseroles normally do not need to be submerged in water to prevent burning. If it is something like a bread pudding than a hot water bath is necessary because it is a custard. However water baths are do not prevent burning. They are to ensure even cooking throughout a dish (usually egg dishes or charcuterie) so that proteins don't coagulate on the outside faster than the center.
If you are worried about not burning a casserole, cover it with tin foil for 2/3's of the cooking time and then finish the dish uncovered.
