Cheesy Potatoes is a rich, comforting casserole that blends tender boiled potatoes with a creamy, savory Gruyère cheese sauce. Perfectly seasoned with a touch of Dijon mustard and nutmeg, the dish balances smooth dairy richness and sharp, nutty cheese. Gruyère adds a sophisticated depth, while a quick broil at the end creates a golden, bubbling topping. Popular as a side dish during holidays or cozy family dinners, it’s a classic example of turning simple pantry ingredients into something luxurious and deeply satisfying.
