1
center-cut beef tenderloin roast, 910 grams to 1.2 kilograms, trimmed of excess fat and silver skin
Extra-virgin olive oil
1 teaspoon
kosher salt
½ teaspoon
freshly ground black pepper
1
large French baguette, cut in half lengthwise
115 grams
arugula
100 grams
shredded Fontina cheese
Instructions
In a small bowl mix the sour cream, horseradish, and mustard.
Allow the roast to stand at room temperature for 15 to 30 minutes before grilling.
Prepare the grill for indirect cooking over medium heat (180º to 230ºC).
Lightly brush the roast with oil and season evenly with the salt and pepper. Brush the cooking grates clean. Sear the roast over direct heat, with the lid closed, until well marked, about 15 minutes, turning a quarter turn every 3 to 4 minutes. Slide the roast over indirect medium heat and continue grilling, with the lid closed, until cooked to your desired doneness, 15 to 20 minutes more for medium rare, turning once. Remove from the grill and let rest for 5 to 10 minutes (the internal temperature will rise a few degrees during this time). Cut into 3-millimeter slices.
Lightly brush the cut side of the baguette with oil and grill, cut side down, over direct heat until lightly toasted, about 30 seconds.
Spread the baguette with the sour cream mixture, layer with arugula and sliced tenderloin, and then top with the cheese. Cut crosswise into individual sandwiches.
