Ingredients

  • 4 tablespoons peppercorns
  • 2 tablespoons kosher salt
  • 4-5 pound beef tenderloin roast
  • 3 tablespoons avocado oil

Potatoes

  • 3 lbs. fingerling potatoes rinsed and patted dry
  • 1 tablespoon kosher salt
  • 4 tablespoons salted butter melted
  • 2 tablespoons mayo or plain Greek yogurt
  • 1 teaspoon sea salt
  • 1 tablespoon dried chives
  • 1 tablespoon fresh rosemary

Instructions

  • Cover a baking sheet with tin foil and then place a metal rack on top.
  • Grind the peppercorns in a mortar and pestle and mix with the kosher salt.
  • Place the tenderloin on the metal wrack. Massage the salt and pepper into the beef tenderloin roast. Transfer the baking sheet to the refrigerator, uncovered to dry out for at least 2 hours.

  • While the meat is resting, prepare the potatoes. Transfer the potatoes to a large pot and cover the potatoes with water. Add the salt to the water and bring to a boil over high heat.
  • Turn the heat to medium and allow the potatoes to cook until fork tender. Strain and set aside.
  • In a separate bowl, whisk together the melted butter, mayo, sea salt, chives, and rosemary.
  • Transfer the potatoes to a large bowl and pour the mayo sauce over the potatoes. Toss until the potatoes are covered. Set aside.
  • Remove the meat from the refrigerator and let it come to room temperature. Preheat the oven to 425ºF.
  • When the meat has come to room temperature, heat the avocado oil in a pan over high heat. When the oil is hot, add the beef tenderloin to the cast iron pan.
  • Sear the beef for 6-8 minutes on 3-4 sides, if possible. The goal is to create a crust on the outside of the tenderloin. The cooking method creates a bit of smoke, so be sure to turn on a fan and open windows.

  • When a crust has formed, check the internal temperature to be sure it is in the lower 100s or upper 90s.
  • Transfer the beef back to the wire rack and bake for 10-15 minutes or until it reaches an internal temperature of 125ºF and remove it from the oven. It will continue to cook when removed from the oven. The goal is to reach an internal temperature of 130-135ºF for a medium rare cut.

Tips & Notes

  • If a smaller beef tenderloin is used, the cook time will decrease. Be sure to check the internal temperature of the meat while searing and baking.
  • This recipe cooks a medium-rare roast. If you prefer your beef more cooked, 140-145°F is optimal for medium doneness (per the USDA). Be careful not to overcook the meat, as it will continue to cook while resting.
  • Let the roast rest before slicing. Resist the temptation to cut into the roast immediately after taking it out of the oven. Allowing it to rest for 15-20 minutes will ensure juicy, tender meat.
