This French Layered Potato and Onion bake is a simple potato dish called Pommes Boulangère or Boulangere Potatoes. It is so easy to make and makes a great alternative to creamy scalloped potatoes or cheesy potatoes au gratin. The thin slices of potatoes and onions are cooked in broth with rosemary until they are soft and tender with a golden crust. A great side dish.

Dot the remaining 2 tbsp of butter over the top of the dish, cover the dish with foil and then transfer the baking dish and tray to the oven.
