Ingredients:
- 4 lbs center-cut beef tenderloin, trimmed and tied
- 2 tbsp avocado oil
- 1 tbsp kosher salt
- 2 tsp freshly cracked black pepper
- 4 tbsp unsalted butter, softened
- 4 cloves garlic, minced
- 1 tbsp fresh thyme, finely chopped
- 1 tbsp fresh rosemary, finely chopped
- 1 tsp prepared horseradish
- 1 cup beef bone broth
- 0.5 cup dry red wine
- 1 shallot, minced
- 1 tbsp cold unsalted butter
Instructions:
- Remove the beef from the refrigerator 45 minutes before cooking to temper. Pat the meat completely dry with paper towels.
- Season the beef aggressively on all sides with kosher salt and cracked black pepper.
- Heat avocado oil in a 12-inch cast-iron skillet over high heat. Sear the beef until a deep mahogany crust forms on all sides.
- In a small bowl, combine 4 tbsp softened butter, minced garlic, thyme, rosemary, and horseradish. Slather the mixture over the seared beef.
- Place the beef on a wire rack set over a rimmed baking sheet. Transfer to a 400°F (200°C) oven.
- Roast until a digital thermometer reads 125°F (52°C) for medium-rare. Pull the meat from the oven and let it rest for 15-20 minutes.
- While resting, sauté shallots in the roasting pan or skillet. Deglaze with red wine and bone broth, simmering until reduced by half. Whisk in 1 tbsp cold butter to finish.
