Preheat your oven to 425°F.
Pat the beef tenderloin dry with paper towels.
In a small bowl, mix together the olive oil, salt, black pepper, garlic powder, rosemary, thyme, Dijon mustard, and balsamic vinegar to create a marinade.
Rub the marinade all over the beef tenderloin, ensuring it is evenly coated.
Place the beef on a roasting rack in a baking dish or on a sheet pan.
Roast in the preheated oven for about 25 to 35 minutes, or until the internal temperature reaches 125°F for medium-rare.
Remove the beef from the oven and tent it with aluminum foil. Let it rest for 10 to 15 minutes before slicing.
Slice the beef into 1-inch thick pieces and serve.
