INSTRUCTIONS
1
Season the filets generously with salt and pepper. In a sauté pan, heat the oil and 1 tablespoon of butter over medium-high heat. Sear the steaks on both sides just until browned, about 2 minutes a side, and remove to a plate.
2
Add remaining butter over medium heat and sauté the shallot until tender. Deglaze the pan with brandy or Cognac. Let it burn off, then stir in the mustard, Worcestershire, and cream. Season again to taste with additional salt and pepper
3
Slide the steaks and accumulated juices in the pan. Cook, turning two or three times, until meat is done to your liking (125°F internal temperature for medium-rare). Remove steaks to a plate. Add lemon juice (if using), salt, and pepper to the sauce as needed. Spoon sauce over meat, garnish with chives or parsley, and serve.
