Pat the beef tenderloin dry with paper towels. Rub with olive oil, salt, and pepper.
Sear the tenderloin in a hot skillet for 2-3 minutes per side.
Roast in the preheated oven for 40-45 minutes, or until a meat thermometer inserted into the thickest part registers 130-135°F (54-57°C) for medium-rare.
Let the beef rest for 10 minutes before slicing and serving.
Notes
For a more flavorful roast, marinate the beef tenderloin overnight.
