Heat oven to 450˚. Place the trimmed tenderloin on a rimmed baking sheet large enough to fit. Rub the tenderloin with the olive oil to coat. Then carefully coat and press the rub mix into the meat, turning to get all sides. Place into the 450 ˚ oven and roast for 5-7 minutes. Turn the oven down to 350 ˚ and roast for 20 -25 minutes or until an instant read thermometer reads 125 ˚ for rare, 130 -135 ˚ for medium rare, 140-145 ˚ for medium and 150-155 ˚ for well done. Remove from oven and let rest for a minimum of 15 – 20 minutes.
