Forget waiting for a special occasion — this Seared Beef Tenderloin with Roasted Garlic and Buttery Herb Sauce brings steakhouse luxury to a weeknight skillet. Thick tenderloin medallions get a hard, caramelized sear, then finish in a bath of foaming butter loaded with sweet roasted garlic and fresh herbs. The result is meltingly tender beef with a rich, savory sauce you’ll want to spoon over everything on the plate.
Ingredients
- 4 beef tenderloin medallions (about 6 oz each, 1½ inches thick)
- 1 head of garlic, top trimmed off
- 6 tbsp unsalted butter
- 2 tbsp olive oil
- 1 tsp kosher salt, plus more to taste
- 1 tsp freshly cracked black pepper
- 2 sprigs fresh rosemary
- 4 sprigs fresh thyme
- 1/3 cup beef broth
- 1 tbsp fresh parsley, chopped
- Flaky sea salt, for finishing
Instructions
- Roast the garlic: Preheat the oven to 400°F (200°C). Place the trimmed garlic head on a small square of foil, drizzle with a teaspoon of olive oil, wrap it up, and roast for 35–40 minutes until the cloves are soft and golden. Squeeze the cloves out of their skins and set aside.
- Prep the beef: Pat the tenderloin medallions completely dry with paper towels and let them sit at room temperature for 30 minutes. Season generously all over with kosher salt and black pepper.
- Sear hard: Heat the olive oil in a large cast-iron or heavy skillet over high heat until it just starts to smoke. Sear the medallions for 2–3 minutes per side until deeply browned with a dark, crusty exterior. Work in batches if needed so the pan stays hot.
- Butter and baste: Reduce the heat to medium-low. Add the butter, rosemary, thyme, and the roasted garlic cloves to the skillet. As the butter foams, tilt the pan and spoon the hot garlic-herb butter over the medallions for 1–2 minutes, until they reach 130°F for medium-rare.
- Make the pan sauce: Transfer the medallions to a warm plate to rest. Pour the beef broth into the skillet, scraping up all the browned bits, and simmer for 2 minutes until slightly reduced. Mash a few roasted garlic cloves into the sauce with a spoon.
- Rest and serve: Let the medallions rest for 5–8 minutes so the juices redistribute. Spoon the roasted-garlic herb butter sauce over the top, sprinkle with chopped parsley and flaky sea salt, and serve immediately.
Pro tip: The roasted garlic is the secret weapon — roasting turns it sweet and creamy, so don’t be shy about mashing extra cloves into the sauce. And use a thermometer, not the clock: pull the medallions at 130°F and let carryover heat finish the job.
