INGREDIENTS

  • 1 (about 2 lbs) whole beef tenderloin
  • 4 tablespoons grass fed butter divided
  • 1/4 cup chopped scallions
  • 2 tablespoons soy sauce (or coconut aminos for soy free)
  • 1 teaspoon dijon mustard
  • 1/4 teaspoon fresh cracked pepper
  • 3/4 cup dry sherry

Horseradish cream sauce:

  • 1/2 cup real mayonnaise
  • 1/2 cup sour cream
  • 1 tablespoon prepared horseradish or horseradish substitute
  • 1 tabelspoon lemon juice

INSTRUCTIONS

  • Preheat oven to 400°F. Tie the beef tenderloin with butcher's twine and place the whole beef tenderloin in a low baking dish or cast iron skillet. Spread 2 tablespoons of butter on top. Place in preheated oven and roast for 20 minutes. Do not open oven.
  • Meanwhile, in a small saucepan, cook the scallions in the remaining 2 tablespoons of butter. Add the soy sauce (or coconut aminos), dijon mustard and pepper and stir to combine. Add the sherry and heat until just boiling for 3-5 minutes. 
  • After roasting for 20 minutes, open the oven and baste the beef tenderloin with the prepared sauce. Baste every 5 minutes for 20 more minutes, for a total cook time of 40 minutes. 
  • Check internal temperature of the beef tenderloin before 40 minutes and remove from the oven when it reaches an internal temperature of 125°F. Transfer to a cutting board and create a tent with foil over top and let it rest for 15-20 minutes. The beef tenderloin temperature should rise to about 135°. 
  • While it's resting, make the horseradish cream sauce. Whisk all the ingredients together until well combined. Refrigerate until ready to serve.
  • Cut into slices and serve with horseradish cream sauce.
