Scalloped Potatoes Au Gratin
Layers of thinly sliced potatoes in a creamy cheese sauce, baked until golden
By RecipesQueen Kitchen • June 10, 2026
Scalloped potatoes are the most luxurious potato side dish — paper-thin slices layered with a silky Gruyère cream sauce and baked until the top is golden and the potatoes are meltingly tender.
Slice the potatoes uniformly thin (1/8 inch) — a mandoline makes this easy. The thinner the slices, the creamier the result.
Let rest 15 minutes before serving so the sauce thickens slightly.
