Ingredients:
- 4 lbs center-cut beef tenderloin, peeled and trimmed
- 2 tbsp kosher salt
- 1 tbsp coarse black pepper
- 2 tbsp avocado oil
- 4 tbsp unsalted butter, softened
- 4 cloves fresh garlic, minced
- 1 tbsp fresh rosemary, finely chopped
- 1 tbsp fresh thyme, finely chopped
Instructions:
- Remove the beef from the refrigerator 60 minutes before cooking. Fold the thin tail end under and tie the roast with kitchen twine at 1.5-inch intervals to ensure even thickness.
- Pat the beef completely dry with paper towels. Rub the surface generously with kosher salt and black pepper. Let the meat sit for at least 45 minutes to dry-brine.
- Heat avocado oil in a large cast-iron skillet over medium-high heat. Sear the whole tenderloin for 2–3 minutes per side until a deep brown crust forms on all sides.
- In a small bowl, mix the softened butter, minced garlic, rosemary, and thyme. Slather the herb butter evenly over the top and sides of the seared beef.
- Place the beef on a wire rack set over a baking sheet. Roast in a preheated oven at 425°F (218°C).
- Using an instant-read thermometer, monitor the internal temperature. Remove the beef when it reaches 120°F (49°C) for medium-rare or 130°F (54°C) for medium.
- Transfer the roast to a cutting board and tent loosely with foil. Let the meat rest for 15 minutes before removing twine and slicing to allow juices to redistribute.
