Scalloped potatoes are a classic comfort food dish made by layering thinly sliced potatoes in a baking dish with a creamy sauce and baking until tender and golden brown. The dish is typically made with sliced potatoes, milk or cream, butter, cheese, and various herbs and spices. The potatoes are arranged in a layer at the bottom of the baking dish, and then the sauce is poured over them.
The dish is then baked in the oven until the top is golden brown and the potatoes are cooked through. Scalloped potatoes can be served as a side dish with a variety of main courses, or enjoyed as a main dish on their own.
