Make Ahead: This dish can be assembled a day ahead; cover tightly with plastic wrap (pressing the wrap directly against the potatoes so they don't discolor), store in the refrigerator, and bake before serving. The potatoes on top will still discolor a bit in the fridge, but it shouldn't be noticeable after baking.
