Ingredients

  • 2 3/4 pounds baking potatoes, peeled and coarsely shredded
  • 2 tablespoons chopped chives
  • 2 tablespoons chopped parsley
  • Salt and freshly ground pepper
  • 6 tablespoons unsalted butter
  • 1/4 cup extra-virgin olive oil
  • Four 1 1/2-inch-thick filet steaks cut from the wide end (6 ounces each)
  • 1/2 cup demiglace
  • 1/2 teaspoon thyme leaves

Method

  • Squeeze as much liquid from the potatoes as possible.

  • In a large nonstick skillet, melt 4 tablespoons of the butter in the oil.
  • Stir in the potatoes and spread in an even layer.
  • Cook over moderate heat, turning once, until the potato cake is golden and crisp, 35 minutes; keep warm.
  • Preheat the oven to 400.
  • Season the meat with salt and pepper.
  • In a large ovenproof skillet, sear the meat over high heat, turning once, until well browned, about 8 minutes.
  • Transfer the skillet to the oven and roast the meat for 15 minutes for medium rare.
  • Transfer the steaks to a plate.
  • Set the skillet over high heat.
  • Add the demiglace and thyme and cook, stirring, until reduced to 1/4 cup.
  • Swirl in the remaining 2 tablespoons of butter and season with salt and pepper.
  • Cut the potato cake into 4 wedges and transfer to warmed plates.
  • Set the steaks on the wedges.
  • Drizzle the sauce around the steaks and serve at once.
