    Scalloped Potatoes vs. Au Gratin Potatoes

    The main difference between scalloped potatoes and au gratin potatoes is the texture. Scalloped potatoes are sliced thin, often with a mandoline slicer, and cooked in a creamy sauce, creating a smooth and creamy texture. Au gratin potatoes are sliced thin and cooked in a roux-based sauce, resulting in a bubbly and golden perfection. Both are classic comfort foods and beloved side dishes. Scalloped potatoes is a simple dish made with only potatoes and a creamy sauce, while au gratin potatoes include cheese and often other ingredients such as onion, garlic or bacon in the dish which gives the dish a more complex flavor. Both dishes are delicious and can be enjoyed as a side dish to any meal.
