Ingredients

  • 1 whole beef tenderloin about 5 pounds
  • Kosher salt
  • cracked black pepper
  • 2 tbsp olive oil
  • ½ cup butter 1 stick - unsalted, softened
  • 4 cloves garlic minced
  • 2 teaspoons horseradish sauce

Instructions

  • Preheat the oven to 450 degrees F.
  • Tie up the tenderloin and season it with salt and pepper as desired.
  • Place the oil in a large cast-iron skillet and heat it over medium-high heat.
  • Sear the beef tenderloin on all sides, about 1 to 2 minutes per side, creating a brown caramelized crust.
  • Meanwhile combine the softened butter, garlic, and horseradish together in a small dish.
  • Spread the seared tenderloin with the butter mixture and then insert a probe thermometer.
  • If using a cast-iron skillet, place it in the preheated oven, or transfer it to a baking dish and then place it in the preheated oven. Roast until the desired internal temperature is reached, about 20 to 30 minutes. *See notes for temperatures.
  • Remove the tenderloin from the oven and transfer it to a cutting board. Let it rest for 15 to 20 minutes to allow the juices to redistribute before slicing it into ¾ inch slices to serve.
