Ingredients
1 center-cut trimmed beef tenderloin, 2 to 3 pounds
Kosher salt and freshly ground black pepper
4 tablespoons unsalted butter
4 sprigs thyme
1 shallot, roughly sliced
Finely minced chives, for serving
Coarse sea salt, such as fleur de sel or Maldon, for serving
1 recipe Horseradish Cream Sauce, for serving
Directions
Using butcher's twine, tie tenderloin at 1-inch intervals using butcher's knots. Season generously with salt and pepper. Transfer to a wire rack set in a foil-lined rimmed baking sheet and refrigerate uncovered at least overnight and up to 2 nights.
Adjust oven rack to center position and preheat oven to 225 degrees F . Place baking sheet with rack and tenderloin in oven and roast until internal temperature registers 120 to 125 degrees F on an instant-read thermometer, 2 to 3 hours. Remove from oven and set aside at room temperature for 10 minutes. Cut and remove twine.
Adjust rack to 6 inches from broiler element and preheat broiler to high. Heat butter, swirling, in a medium skillet over high heat until foaming subsides and butter turns a light nutty brown. Add thyme and shallots and stir until crackling stops. Pour butter mixture over tenderloin and spread with a spoon until all surfaces are coated. Remove shallots from top surface of meat. Place pan with tenderloin under broiler and broil, turning every 30 seconds, until meat is well browned on all sides and internal temperature registers 125 degrees F for rare or 130 degrees F for medium-rare, about 2 minutes total. Proceed to step 5.
Heat butter, swirling, in a medium skillet over high heat until foaming subsides and butter turns a light nutty brown. Add tenderloin, shallots, and thyme and cook, turning occasionally and spooning hot butter and aromatics over roast, until meat is well browned on all sides and internal temperature registers 125 degrees F for rare or 130 degrees F for medium-rare, about 1 1/2 minutes. Transfer tenderloin to a cutting board and allow to rest for 5 minutes. Slice into 1/2-inch slices, sprinkle with chives and coarse sea salt, and serve with Horseradish Cream Sauce.
