Sweet Potato Pommes Anna (Layered Potato Casserole)
This multicolored galette is a fun twist on the classic dish made with white potatoes. Don't worry if you only have one type of sweet potato, the result will still be beautiful. The bottom bakes to a potato-chip crisp with a caramelly sweetness, while the interior becomes melt-in-your-mouth rich.
Equipment: 8-inch cast-iron skillet, mandoline
