01 - Preheat the oven to 425°F. Line a roasting pan with foil or parchment paper for easy cleanup.
02 - Pat the beef dry with paper towels and tie with kitchen twine at 2-inch intervals to ensure even cooking.
03 - Rub the tenderloin evenly with 1 tablespoon olive oil. Season all sides with kosher salt and freshly ground black pepper.
04 - Combine rosemary, thyme, parsley, minced garlic, Dijon mustard, and 1 tablespoon olive oil in a small bowl and mix into a thick paste.
05 - Spread the herb mixture uniformly over the beef surface, pressing gently to adhere.
06 - Place the beef on a rack in the prepared roasting pan and roast for 30 to 35 minutes, or until the internal temperature reaches 130°F for medium-rare.
07 - Remove the tenderloin from the oven, tent loosely with foil, and let rest for 15 minutes before slicing.
