Au Gratin Potatoes Recipe (Real French Technique, Cheese Included)

Au gratin potatoes with golden bubbling cheese in a baking dish

Au gratin potatoes are thinly sliced potatoes layered with cream and cheese, usually gruyere or sharp cheddar, then baked until the potatoes are tender and the top is browned and bubbling, distinct from scalloped potatoes, which traditionally skip the cheese entirely. Most people use these two names interchangeably, and honestly, most recipes online do too.
