Potatoes au Gratin
在这个富有,美丽的奶油烤菜,土豆和洋葱s are arranged in concentric circles, coated in a creamy cheese sauce, and topped off with a few more handfuls of shredded cheese. Cheddar and Gruyère work wonderfully here, but feel free to substitute with another one of your favorite melting cheeses, such as Fontina or Havarti. A quick run under the broiler at the end browns the top of the gratin for a little extra flavor and texture.
