A quick and easy recipe for two featuring tender beef tenderloin steaks with a rich, creamy mushroom sauce enhanced by cognac. Perfect for intimate dinners or special occasions.

Ingredients

Scale
  • 2 beef tenderloin steaks (about 6 oz / 170 g each, 1 to 1.5 inches thick)
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 cup cremini or button mushrooms, thinly sliced
  • 2 tablespoons shallots, finely chopped
  • 1 clove garlic, minced
  • 1/4 cup cognac or brandy
  • 1/2 cup beef broth
  • 1/4 cup heavy cream
  • 1 teaspoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • 2 tablespoons unsalted butter (for finishing the sauce)
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Pat steaks dry with paper towels and season both sides generously with salt and freshly ground black pepper. Let rest at room temperature for 10-15 minutes.
  2. Heat a heavy skillet or cast-iron pan over medium-high heat and add 1 tablespoon olive oil. Heat until shimmering but not smoking, about 2 minutes.
  3. Place steaks in the pan and cook for 3-4 minutes on the first side without moving to create a crust. Flip and cook for another 3 minutes for medium-rare. Add 2 tablespoons butter during the last minute and spoon melted butter over steaks.
  4. Remove steaks from pan and transfer to a warm plate. Tent loosely with foil and rest for 5-7 minutes.
  5. Reduce heat to medium. Add chopped shallots and garlic to the same skillet and sauté for 1-2 minutes until fragrant.
  6. Add sliced mushrooms and cook, stirring occasionally, until golden brown and moisture is released, about 5-6 minutes.
  7. Carefully pour in 1/4 cup cognac and let it simmer for 1 minute, scraping up browned bits from the pan.
  8. Add beef broth and bring to a gentle simmer. Reduce by half, about 5 minutes.
  9. Lower heat and stir in heavy cream, Dijon mustard, Worcestershire sauce, and remaining 2 tablespoons butter. Cook gently until sauce thickens and coats the back of a spoon, about 3-4 minutes. Adjust seasoning with salt and pepper.
  10. Serve steaks on plates, spoon mushroom sauce over the top, and garnish with chopped fresh parsley if desired.

Notes

For dairy-free, substitute heavy cream with coconut cream and butter with olive oil. Use gluten-free Worcestershire sauce for gluten-free diet. Let steaks rest after cooking for juicy results. Be cautious when adding cognac to hot pan due to flare-ups. If sauce is too thick, add broth; if too thin, simmer longer.
