Preparation

Step 1

1.Preheat oven to 400 degrees.
2.Place red wine, vinegar, shallot, peppercorns, and thyme in a small saucepan over high heat; cook until reduced to 1/2 cup, about 10 minutes. Remove from heat and set aside.
3.Generously season tenderloin on all sides with salt and pepper. Heat oil in a large heavy-bottomed roasting pan over high heat. Carefully add tenderloin and transfer roasting pan to oven. Roast, turning every 5 minutes, until medium-rare (120 degrees on an instant-read thermometer), 12 to 20 minutes.
4.Meanwhile, slowly whisk the cold butter into the warm wine reduction until emulsified. Strain through a fine mesh sieve into a small saucepan; season with salt and pepper and keep warm.
5.Remove tenderloin from oven and let stand for 5 minutes. Transfer to a cutting board and slice crosswise; arrange slices on a large platter. Pour any juices that have accumulated in the roasting pan into the red-wine sauce and stir to combine. Serve beef accompanied with sauce.
