Preheat your oven to 425°F (220°C).
Trim any excess fat or silver skin from the beef tenderloin.
Rub the beef tenderloin with olive oil and season generously with salt and pepper. Press the seasoning onto the meat.
Heat an ovenproof skillet over medium-high heat. Once hot, sear the beef tenderloin on all sides until it's nicely browned, about 2-3 minutes per side.
Add the minced garlic and fresh thyme to the skillet. Tilt the skillet and spoon the hot oil over the meat to infuse flavor.
Transfer the skillet to the preheated oven and roast for about 20-25 minutes for medium-rare, adjusting the time for your preferred level of doneness. Use a meat thermometer to check doneness (145°F or 63°C for medium-rare).
Remove the beef tenderloin from the oven and let it rest on a cutting board for 10 minutes. This allows the juices to redistribute, ensuring a juicy tenderloin.
Slice the beef tenderloin into thick rounds and serve with your favorite side dishes. Enjoy your simple and delicious Beef Tenderloin!
