  • 2 pound center-cut tenderloin roast chateaubriand, tied
  • 2 teaspoons sea salt
  • 1 teaspoon fresh ground black pepper
  • ½ teaspoon garlic powder
  • 2 tablespoons avocado oil
  • 2 tablespoons unsalted butter


  • Preheat the oven to 250° F.
  • In a small dish, mix together the salt, pepper, and garlic. Rub the mixture on top of the beef.
  • Place a wire rack on a rimmed baking sheet. Allow to sit in the refrigerator overnight.
  • If desired, use cooking twine to tie the tenderloin at even intervals.
  • Place the tenderloin on top of the wire rack and roast until the center of the meat reaches 120° F for medium-rare. (About 1 hour.)
  • Heat the oil and butter in a heavy skillet to high heat.
  • Add the tenderloin and sear on all sides until brown, about 6 minutes.
  • Transfer to a cutting board and tent with foil.
  • Allow to rest for at least 20 minutes before carving.
