This creamy scalloped potatoes dish is a rich, comforting side that layers thinly sliced potatoes in a silky cream sauce and bakes them until tender and golden. The sauce, made with milk, cream, and a touch of butter, seeps between the potato slices, creating a luscious texture. A blend of cheeses adds depth and a bubbly, golden finish. It’s ideal for holiday meals, family dinners, or whenever you want a satisfying classic side. Scalloped potatoes are timeless because they combine simplicity with indulgent flavor and pleasing textures, making them a favorite around the table.
