What Are Potatoes Gratin?
Potatoes au gratin is a French dish consisting of thinly sliced potatoes with cheese, cream, and butter. The dish is baked to a crisp golden top with a cheesy, bubbling interior.
The French word “au gratin,” meaning “to brown,” refers to a dish covered in cheese or breadcrumbs. The gratin method can be used with a number of different ingredients, though the potato version has become the most popular.
While scalloped potato is often confused with it, they are different. The sauce used to make scalloped potatoes is cream- or milk-based and does not always include cheese. In contrast, potatoes au gratin are always made with generous cheese. It gives them their signature richness.
