Instructions
Begin by heating canola oil in a large 12-inch skillet over medium-high heat until shimmering hot. Generously season the beef fillets on both sides with salt and freshly ground pepper. Carefully place the steaks into the skillet, allowing them to sear undisturbed for 4 to 5 minutes until a rich brown crust forms. Flip the steaks to the other side and cook to your preferred doneness — medium-rare is ideal here for tenderness. Once cooked, transfer the steaks to a warm plate and cover loosely to keep warm while you prepare the sauce. Return the skillet to high heat and pour in the beef stock. Allow it to simmer and reduce down to about half a cup over approximately 10 minutes, concentrating the flavors. Pour the reduced stock into a separate bowl and set aside. Next, reduce the skillet to medium-high heat and add butter. When melted, stir in the minced garlic and finely diced shallots, cooking until they become soft and fragrant, about 2 minutes. Add the mushrooms and sauté, stirring occasionally, until they release their moisture, which then evaporates, and the mushrooms turn a beautiful golden brown, roughly another 2 minutes. Carefully pour in the brandy and ignite it with a match to flambé. This dramatic step burns off the alcohol and infuses the sauce with a smoky, caramelized flavor. Allow the flames to subside naturally. Stir in the reserved reduced stock along with heavy cream, Dijon mustard, Worcestershire sauce, and a dash of Tabasco sauce for a subtle kick. Return the steaks to the skillet, nestling them into the sauce. Continue cooking for about 4 minutes, gently turning the steaks to coat them thoroughly and warm them through as the sauce thickens to a luscious consistency. Finally, remove the skillet from heat and sprinkle minced parsley and chives into the sauce. Transfer the steaks to serving plates and generously spoon the rich, flavorful sauce over top. For a beautiful presentation, garnish with additional fresh herbs if desired. Serve immediately and enjoy this timeless dish!
