*READ THROUGH ALL INSTRUCTIONS AND NOTES BEFORE STARTING*

One to Two Days Ahead...

• Line a rimmed baking sheet with foil and set a wire rack inside or over the baking sheet.
• Tie the tenderloin with butcher’s twine at 1-inch intervals.
  3 pounds beef tenderloin
  
• Generously season all sides with salt and peppercorns (or pepper).
  Kosher salt, ¼ cup black peppercorns
• Set the beef on the wire rack and transfer to the refrigerator (uncovered) to chill for at least 8 hours and up to 48 hours.

When Ready to Cook...

• Set the oven rack to the middle position and preheat oven to 225°F.
• Place the beef with the rack and baking sheet onto the kitchen counter 30 minutes before cooking.
  
• After 30 minutes, transfer the tenderloin/rack/baking sheet to the oven and cook 2-3 hours, or until a meat thermometer, placed in the center of the tenderloin, registers 120°-125°. Remove the beef from the oven for 10 minutes and cut off the twine.
  

To Finish Under the Broiler...

• Place the oven rack 6 inches from the broiler element and set the oven to broil.
• Heat a cast iron skillet over medium heat and add the butter. Melt the butter, while gently swirling the pan, until foaming subsides and butter turns a light brown and has a nutty fragrance (be careful not to burn the butter).
  ½ cup unsalted butter
  
• Reduce the heat to medium-low and add the thyme, garlic and shallots. Cook 30-60 seconds after the crackling stops. Pour the seasoned butter through a mesh strainer over a medium bowl.
  4 sprigs fresh thyme, 2 cloves garlic, 1 shallot
  
• Pour the butter mixture evenly over the tenderloin and brush with a silicone brush or baste with a spoon until all surfaces are coated.
  
• Place the pan with the tenderloin under the broiler and broil, turning every 30 seconds, until meat is browned on all sides, baste each time the meat is turned.
• Transfer the tenderloin to a cutting board. Let is rest 5-10 minutes and slice into ½–inch slices.
  
• To serve, sprinkle with coarse sea salt and chives (if desired) and serve with Brandy Peppercorn Sauce, our personal favorite (see recipe) or Horseradish Sauce (see recipe).
