Preheat oven to 400 degrees F.
Drizzle olive oil on both sides of tenderloin and season generously with salt and pepper.
Tuck narrow end of tenderloin under the top to even out the thickness of the roast.
Place tenderloin on a roasting rack in a roasting pan.
Roast for 30-40 minutes or until internal temperature reaches 140 degrees F (for rare to medium rare). Remove from oven and let rest on a cutting board under tented foil for 5 minutes.
To serve, slice into 1/2 inch pieces and plate alongside gourmet mushrooms or your favorite vegetable side.
