What Does Potatoes Au Gratin Mean?
Typically this refers to a French-style casserole where you've created a browned crust on top of a dish. Sometimes this is done with breadcrumbs, sometimes cheese--or if you're craving some good old-fashioned American topping, I've seen this done with crushed, buttered corn flakes.
I will not judge, because by golly that cornflake topping is delicious!
I debated whether this cheesy potato casserole was au gratin or not since I don't use a breadcrumb topping for them. But the simplest way to get a browned crust on these--and also a delicious way to do that--is to top with grated cheese for the final 2-3 minutes of cooking.
