What's the difference between Scalloped Potatoes and Au Gratin Potatoes?
Both recipes use thinly sliced potatoes layered in a baking dish and cooked with a creamy sauce. Au Gratin Potatoes (pronounced ‘oh grah-tin’) or Potatoes au Gratin, include grated cheese or a cheese sauce in the recipe. It can also have a browned bread crumbs crust on top too. The main difference is that scalloped potatoes do not include cheese.
