Ingredients:
- Beef Tenderloin Roast: 3-4 lbs (1.4-1.8 kg), trimmed of silver skin
- Olive Oil: 2 tablespoons (30 ml), extra virgin
- Salt: 2 tablespoons (36 g), kosher or sea salt
- Black Pepper: 1 tablespoon (8 g), freshly ground
- Fresh Rosemary: 2 sprigs, roughly chopped
- Garlic: 4 cloves, minced
Instructions:
- Pat the tenderloin dry with paper towels. Season generously with salt, pepper, rosemary, and garlic. (Consider tying the roast with kitchen twine at 2-inch intervals to ensure even cooking).
- Heat olive oil in a large cast-iron skillet over high heat until shimmering. Sear the tenderloin on all sides until deeply browned (about 2-3 minutes per side).
- Transfer the skillet to a preheated oven (400°F/200°C). Roast until the internal temperature reaches 130°F (54°C) for medium-rare (adjust for desired doneness).
- Remove the tenderloin from the oven and let it rest, uncovered, for at least 10 minutes before slicing. Resting allows the juices to redistribute.
- Slice the tenderloin against the grain into 1/2-inch thick slices. Serve immediately.
