Ingredients

  • 4 pound beef tenderloin (4-5 pounds) - each pound serves 2-3 people
  • 2-3 tablespoons canola oil
  • 1/2 cup salted butter divided
  • 1 tablespoon coarse sea salt
  • 1 tablespoon whole black peppercorns
  • 5 cloves garlic minced (plus whole cloves for roasting, if desired)
  • Fresh herbs for garnish optional

Instructions

  • Prepare beef tenderloin by trimming (if it didn’t come trimmed). Set out tenderloin 1-2 hours before cooking so that it can come to room temperature.
  • Cut the tenderloin into two pieces, if needed, so that it will fit into a cast iron or oven-safe skillet. Tuck the long skinny end under itself to form a roast that is uniform in thickness. Tie with kitchen twine to secure.
  • Preheat oven to 450°F.
  • Coat tenderloin with coarse sea salt and cracked black peppercorns. The exact amount will vary, but sprinkle liberally and coat all sides of the tenderloin.
  • In a large skillet, heat canola oil over medium-high heat until oil begins to smoke. Place the tenderloin into the skillet and sear. Brown on each side for 3-4 minutes.
  • Spread 4 tablespoons of butter over the top and sides of the browned tenderloin. Add whole garlic cloves to the pan around the meat. Add a teaspoon of minced garlic to the top of the meat, if desired.
  • Place in the oven for 25-30 minutes or until the center of the meat registers 120-125°F (for medium rare meat).
  • Remove from the oven and tent with aluminum foil for 10 minutes (the juices will redistribute and the temperature should continue to rise to about 130-135°F.
  • Heat the remaining 1⁄4 cup of butter and minced garlic over medium heat until the butter begins to turn golden brown. Remove from heat and set aside.
  • Remove the twine from the tenderloin and slice into 3⁄4” sections. Drizzle with the garlic browned butter.
  • Garnish with a bit of freshly chopped parsley if desired. Serve immediately.
