Ingredients

  • Beef steak (ribeye or strip steak):1.1 lb
  • Potatoes:14 oz
  • Fresh button mushrooms:9 oz
  • Butter:2 oz
  • Olive oil:3 tbsp
  • Beef stock:5 fl oz
  • Heavy cream:3.5 fl oz
  • Garlic cloves:3 pieces
  • Fresh thyme:2 tbsp
  • Sea salt:to taste pinch
  • Black pepper, freshly ground:to taste pinch

Instructions

  1. Remove the beef steak from the refrigerator 30 minutes before cooking. Pat it dry with paper towels, then season generously with salt and pepper on all sides.

  2. Cut the potatoes into ½-inch cubes. Heat the olive oil in a large skillet over medium heat and fry the potatoes for 12-14 minutes until golden brown on all sides. Season with salt and pepper, then transfer to a plate.

  3. In the same skillet over high heat, melt 1 oz of butter. Once the butter becomes fragrant and turns nutty brown, place the steak in the pan and sear for 4-5 minutes on each side for medium-rare doneness. Remove the steak to a warm plate and let it rest for 5 minutes.

  4. Slice the mushrooms and sauté them in the skillet over medium heat with the crushed garlic for 6-7 minutes until tender. Pour in the beef stock and heavy cream, bring to a simmer, then stir in the remaining butter and fresh thyme.

Tips & Notes

  • Don't move the steak around in the pan—flip it only once to keep it juicy and develop a beautiful crust.
  • Always bring your steak to room temperature before cooking for even doneness throughout.
  • Check doneness by gently pressing the meat with your finger: at medium-rare, it should spring back slightly.
  • Let the steak rest before serving to keep it tender and juicy.
  • For a richer sauce, add a splash more stock or cream to achieve your preferred consistency.
