Boulangère potatoes are a French dish that has layers of thinly sliced potatoes that have been layered with onions in a pan and then covered in stock. This ensures the top layers become nice and crispy in the oven, while the bottom layers are thick and creamy. They’re often served as a side dish to roasted meats. Sage and Gruyere cheese make this an herby, cheesy masterpiece.
