If you can get your hands on some French reblochon, your Christmas eve dinner is golden. Even if you can't find the melty-licious, nutty, creamy cheese, just sub Brie or Camembert to make this comforting tartiflette recipe. The base is composed of sliced potatoes, lardons (sub bacon, if desired) and onions cooked in dry white wine, before being topped with glorious wheels of cheese and baked to rich perfection.
