Potato Gratin Dauphinois | www.oliviascuisine.com | Gratin Dauphinois might sound fancy, but it's just a side dish made of thinly sliced potatoes, cream and cheese. Possibly my favorite potato recipe of all time, this decadent French classic - bubbling and cheesy, with a gorgeous caramelized top - is absolutely irresistible! #potatodauphinoise #gratindauphinois #dauphinoisepotatoes #potatogratin
