This casserole has changed my mind about serving mashed potatoes without gravy. Just one bite won me over. Even more than texture and flavor a huge bonus is that it can be made the day before, or even two. Just cook the potatoes, assemble the casserole, wrap tightly and store it in the refrigerator. When it is serving time just top the dish with cheese, butter and bread crumbs and bake!
