So. Midwestern cookery is what I was weaned on, and as such I have an inordinate love for that composed, oven baked wonder: The Hot Dish. However, I am not certain what, exactly defines "Hot Dish," and what, if anything, differentiates it from good ol' plain casserole. Any ideas? I mean, I have had them w/ bases of every kind of rice, every kind of potato, any type of meat, and some sort of sauce. Usually it involves a gratin topping of some sort (even if you stretch the definition to include the crushed French's fried onion). What say you? And what's your favorite, and why?
