I had dinner at a friend's the other night and his wife made meatloaf. The house smelled great when I came in and when she pulled the meatloaf out of the oven, its was (to my shock and horror) still in the loaf pan! I've always made mine molded into a "loaf" and cooked on a sheet pan. They said they've never seen it done that way and I said the same to them about the in-pan method. So, fellow Serious Eaters; in-pan or out?
