  • 2 8 ounce New York Strip, flat iron, or beef tenderloin steaks 1 inch thick or less
  • 1 Tablespoon vegetable oil
  • ¼ tsp. kosher salt and pepper
  • 1 Tablespoon butter
  • 8 ounces cremini or white button mushrooms cleaned and sliced
  • 2 cloves garlic
  • ½ small onion or 2 shallots minced
  • ¼ cup Cognac or brandy
  • 1 Tablespoon Dijon mustard
  • 1 Tablespoon Worcestershire sauce
  • ½ cup beef broth
  • ¼ cup heavy whipping cream
  • ¼ cup chopped chives or parsley for garnish optional


  • Steaks should be 1-inch thick or less. If steaks are too thick place a piece of plastic wrap over the top and pound with a meat mallet.
    Season both sides of the steak with ⅛ teaspoon of kosher salt and black pepper. Allow to sit at room temperature for 15 minutes.
    Mince garlic and small onion (or shallots). Wipe mushrooms clean and cut into slices.
    Heat a large cast iron skillet to medium-high with 1 Tablespoon of vegetable oil. Once hot, add both steaks to the pan and sear for 4-8 minutes on the first side to form a brown crust. Flip and sear another 4-8 minutes on the opposite side.
    Internal temperature of the steak should read at least 145°F. Remove the steaks, place them on a plate, cover with foil, and allow to rest.

  • Remove skillet from heat, add ¼ cup of Cognac or brandy to the pan, and return to the heat. Be careful as alcohol may cause a flame.
    Saute for 1-2 minutes and allow the alcohol to cook down.
    Add 1 Tbsp. Dijon mustard, 1 Tbsp. Worcestershire sauce, and ½ cup of beef broth. Stir to incorporate.
    Add ¼ cup heavy whipping cream to the skillet. Stir and allow to cook for 5 minutes or so. The sauce should thicken a bit as it cooks.

  • Use steaks that are already tender for best results, such as flat iron steaks, strip steaks, or beef tenderloin steaks.
  • You want your cuts of steak to be 1 inch thick or less. This will ensure they are easy to cook and do not take a long time to pan fry.
  • Cooking times will vary depending on the thickness of your steak and desired level of doneness.
