What is the difference between scalloped potatoes and au gratin potatoes?

Scalloped potatoes are much simpler. Most recipes call for the potatoes to be baked in a basic cream sauce (usually a mix of milk and heavy cream), and that’s it. Potatoes au gratin are a bit more decadent. They are made with lots of cheese sprinkled in between the layers of potatoes and also on top of the casserole.
