What is the difference between Dauphinois and Lyonnaise?
Dauphinois (meaning "from Dauphiné" in French) potatoes are a French side dish of thinly sliced raw potatoes layered with cream, milk, and sometimes Gruyère cheese, and baked. Lyonnaise (meaning "from Lyon" in French) potatoes are also a French dish of layered potatoes, but they are pan-fried in butter with onions and parsley.
