La Morbiflette is a gratin de pommes de terre that greatly resembles the better-known Tartiflette, which is made not far south of Geneva (Switzerland) in the Alps in the area called la Savoie. The little town of Morbier (pop. 2,400 or so) is just 25 miles north of Geneva.
Both of these gratins are made of blanched (partially cooked) potatoes peeled and then sliced into rounds before being browned lightly in oil or butter on a baking sheet in the oven or in a frying pan on the stovetop. The rondelles de pomme de terre are arranged in a baking dish in layers and cooked in a hot oven with sauteed onions and smoked lardons, along with cream, white wine, and Morbier cheese.
The Morbier cheese's distinctive feature is a line of vegetable ash that runs through the middle of a wheel of the cheese. Morbier is mild-tasting (as is the cheese that the Tartiflette is made from, called Reblochon) and melts smoothly. The crust of both these cheeses is edible, like the crust of Brie or Camembert, as is the ash in the Morbier. (The broccoli in my photos is some that I steamed for us to have as a side dish.)



After you sautee the onions and lardons, lightly oil an oven-proof dish and put in a first layer of sliced potatoes. Then put a layer of sauteed onions and lardons over them. Put on another layer of potatoes and pour on some cream and a splash of white wine. Slice the Morbier cheese and spread the slices over the potato mixture. Cook the Morbiflette in a hot oven until the potatoes are tender and the cheese has melted and started to turn a golden brown color. The cream and wine will have mostly evaporated when the Morbiflette is done. Be careful not to burn your mouth when you eat it.
P.S. If you're in the U.S. I don't know whether you can find Morbier cheese or not. I believe the Reblochon cheese used to make a Tartiflette is not imported into the U.S. Also, my innovation here was to make the Morbiflette not with smoked-pork lardons but with diced-up smoked chicken that I happened to have in the refrigerator.
