Begin by trimming any excess fat from the beef tenderloin and patting it dry with paper towels. Tie up the tenderloin at regular intervals using kitchen twine.
In a mixing bowl, combine olive oil, minced garlic, rosemary, thyme, salt, and pepper. Rub this mixture all over the tenderloin.
Preheat your oven to 450°F (230°C). Heat a large skillet over medium-high heat and add butter. Sear the tenderloin on all sides until golden brown.
Transfer the seared tenderloin to a roasting pan and insert an oven-safe meat thermometer. Roast until the internal temperature reaches 130°F (54°C) for medium-rare.
Remove from oven and let it rest for at least 15 minutes under a foil tent. Slice and serve.
Notes
Store leftovers in an airtight container for up to 3 days. This dish pairs wonderfully with a red wine reduction sauce.
