If you are looking for a great au gratin recipe, this is it. I made this as a side dish for Easter Sunday dinner and it was a hit. So much so that there weren't any left! To make things easier, I sliced the potatoes the night before, put them in a ziploc bag with water and kept them in the fridge. The potatoes stored well that way and cut some prep time when I had several other dishes to make. I recommend trying this dish.
