Instructions

  1. Step 1: Pat the beef tenderloin dry with paper towels, then season evenly with 1 tsp salt and 1/2 tsp black pepper. Melt 3 tbsp unsalted butter in a small bowl, then stir in 2 tbsp finely chopped rosemary, 2 tbsp finely chopped thyme, and minced 2 garlic cloves until fully combined.
  2. Step 2: Rub the herb butter mixture over the entire surface of the beef tenderloin, pressing gently to adhere. Heat 2 tbsp avocado oil in an oven-safe skillet over medium-high heat until shimmering.
  3. Step 3: Sear the beef in the skillet for 2-3 minutes per side until deeply browned, then transfer the skillet to a preheated 400°F (200°C) oven. Roast for 15-18 minutes for medium-rare, until the internal temperature reaches 125°F (52°C). Remove from oven, tent loosely with foil, and rest for 10 minutes before slicing.
