Ingredients

  • 1/4 pound sliced bacon, cut crosswise into 1/2-inch lardons
  • 1 yellow onion, peeled and diced
  • 8 leaves fresh sage, roughly chopped
  • 1 1/2 pounds small, waxy yellow potatoes, peeled and cut into bite-size pieces
  • 1/2 teaspoon freshly grated nutmeg
  • 1/2 cup creme fraiche
  • Coarse salt
  • 1/3 pound Reblochon cheese or any soft, washed-rind cheese such as Brie)
  • 2 tablespoons heavy cream

Method

  • Preheat the oven to 425F.
  • Place the bacon into a large, heavy, ovenproof skillet over medium heat.
  • Cook, stirring occasionally, until all of the fat has nearly rendered and the bacon is just beginning to crisp, 5 to 10 minutes.
  • Add the onion to the skillet and cook, stirring occasionally, until softened, another 10 minutes.
  • Add the sage and potatoes and cook, stirring occasionally, until the onions are quite brown and sticky, almost like a jam, and the potatoes are just cooked through, 20 to 25 minutes.
  • Stir the nutmeg and creme fraiche into the potato mixture and season with salt.
  • At this point you can transfer the potato mixture to a gratin dish or individual ramekins or simply leave them in the skillet.
  • Blanket the potato mixture with slices of the cheese and evenly pour over the cream.
  • Place the skillet in the oven and bake until the cheese has melted and browned, about 15 minutes.
