Start to finish: 1 hour, 20 minutes (plus 30 minutes resting time)
1 (2-pound) center-cut beef tenderloin roast, trimmed, tail end tucked, and tied at 1 1/2-inch intervals
2 teaspoons kosher salt
1 teaspoon pepper
2 tablespoons unsalted butter, softened
1 tablespoon vegetable oil
Shallot and Parsley Butter:
4 tablespoons unsalted butter, softened
1/2 shallot, minced
1 tablespoon minced fresh parsley
1 garlic clove, minced
1/4 teaspoon salt
1/4 teaspoon pepper
For the beef: Sprinkle roast evenly with salt, cover loosely with plastic wrap, and let stand at room temperature for 1 hour. Adjust oven rack to middle position and heat oven to 300 F.
For the shallot and parsley butter: Meanwhile, combine all ingredients in bowl and let rest to blend flavors, about 10 minutes. Wrap in plastic wrap, roll into log, and refrigerate until serving.
Pat roast dry with paper towels. Sprinkle roast evenly with pepper and spread softened butter evenly over surface. Transfer roast to wire rack set in rimmed baking sheet. Roast until beef registers 120 F to 125 F (for medium-rare), 40 to 55 minutes, flipping roast halfway through roasting.
Heat oil in 12-inch skillet over medium-high heat until just smoking. Brown roast well on all sides, about 8 minutes. Transfer roast to carving board and spread 2 tablespoons flavored butter evenly over top of roast; let rest for 30 minutes. Remove twine and slice into 1/2-inch-thick slices. Serve, passing remaining flavored butter separately.
