  • 1 pound beef tenderloin - 4 steaks
  • 1 pound mushrooms washed and chopped
  • 2 cloves garlic minced
  • 2 tbsp olive oil divided
  • 2 tbsp butter divided
  • 1/2 tsp salt
  • 1/2 tsp pepper


  • Let the beef tenderloin steaks come to room temperature before cooking. Take them out of the fridge about an hour before starting this dish.
  • Preheat the oven to 425-F.
  • Add 1 tbsp oil and 1 tbsp butter to the oven-safe skillet and sautee the garlic and mushrooms for two minutes. Remove mushrooms and garlic.
  • Season the steaks well with salt and pepper. Add the remaining oil and butter to the skillet and heat until very hot but not smoking.
  • Add the steaks and sear about 2 minutes per side. You're looking for a good, dark sear, but don't burn them!
  • Add the mushrooms to the skillet and pop the whole skillet into the heated oven. Cook for about 4 minutes at 425-F for medium-rare. Use a digital meat thermometer to get an accurate internal temperature.
  • Remove the steaks and let rest for about five minutes before serving.
  • Enjoy!
