🛒 Ingredients

4 servings

4
  • 500 g (1.1 lb) filet mignon, cut into thin medallions
  • 200 g (7 oz) canned sliced mushrooms, drained
  • 1 heaping tablespoon all-purpose flour
  • 2 cups hot water
  • 1/2 beef bouillon cube
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon cognac or brandy
  • 1 tablespoon soy sauce
  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • Salt and black pepper to taste

Directions

  1. 1

    Season the medallions with salt and pepper. Melt butter in a skillet over high heat and sear for 2–3 minutes per side until golden brown. Remove from heat and rest, loosely covered with foil.

  2. 2

    In a small saucepan, gradually whisk the flour into the hot water to avoid lumps. Add the crumbled bouillon cube and cook over medium heat, stirring, until slightly thickened. Set aside.

  3. 3

    In the same skillet, heat olive oil over medium heat and sauté the sliced mushrooms for 4–5 minutes until golden.

  4. 4

    Pour the cognac over the mushrooms and carefully flambé. Let the flames die out on their own, then stir in the Worcestershire sauce and soy sauce. Let reduce for 1 minute.

  5. 5

    Pour in the reserved broth and simmer over low heat for 3–4 minutes until the sauce is smooth and glossy. Adjust salt as needed.

  6. 6

    Plate the medallions and spoon the sauce generously on top. Serve immediately with steamed white rice and crispy golden potatoes.

💡 Chef's Tip

Avoid overcooking the filet mignon — a slightly pink center keeps the meat tender and juicy. Fresh button mushrooms can replace canned ones for a deeper, earthier flavour.
