Instructions:
Prepare the Herb Butter:
In a small bowl, mix the softened butter with minced garlic, chopped rosemary, thyme, parsley, Dijon mustard, salt, and pepper. Stir until fully combined. 
Season the Beef:
Rub the beef tenderloin all over with olive oil, then generously season it with salt and pepper. Make sure the meat is well-coated. 
Apply the Herb Butter:
Spread the herb butter mixture evenly over the entire surface of the beef tenderloin. Make sure to coat all sides for maximum flavor. 
Roast the Beef:
Preheat your oven to 425°F (220°C). Place the beef tenderloin on a rack in a roasting pan or on a baking sheet lined with foil. Insert a meat thermometer into the thickest part of the roast. 
Roast in the preheated oven for 25-30 minutes for medium-rare (until the internal temperature reaches 130-135°F/54-57°C), or adjust cooking time for your desired doneness. 
Rest the Roast:
Once the roast reaches your desired internal temperature, remove it from the oven and loosely cover it with aluminum foil. Let it rest for 15-20 minutes to allow the juices to redistribute throughout the meat. 
Slice and Serve:
Slice the beef tenderloin into thick slices and serve on a platter. Garnish with fresh rosemary and thyme sprigs for a beautiful presentation. 
Enjoy your elegant Herb Butter Beef Tenderloin Roast—it’s perfect for special occasions or an impressive dinner!
