A quick and elegant steak dish featuring tender filet mignon steaks in a rich, buttery, tangy sauce made with Dijon mustard, Worcestershire sauce, and brandy. Perfect for special occasions or a sophisticated weeknight dinner.
Use room temperature steaks for even cooking. Rest steaks after searing to keep them juicy. When flambéing, keep a lid nearby for safety. For dairy-free, substitute butter with plant-based alternative. For alcohol-free, replace brandy with extra beef stock and lemon juice. Sauce should coat the back of a spoon; add stock or water if too thick.
