Preheat the oven to 425°F. Place the tenderloins in a shallow baking dish.
Combine the olive oil, mustard, garlic, salt and pepper to taste, rosemary, and thyme in a small bowl. Rub the mixture evenly onto the tenderloins. Roast for 25 to 30 minutes, or until an instant read thermometer registers 145°F. Let rest for 5 minutes before cutting into thick slices and serving.
