Horseradish-Crusted Beef Tenderloin

Preheat oven to 400 degrees F.

Combine horseradish, oil and mustard in

a small bowl. Rub tenderloin with salt and pepper; coat with the horseradish mixture. Tie with kitchen string in 3 places. Transfer to a small roasting pan.

Roast until a thermometer inserted into the thickest part of the tenderloin registers 140 degrees F for medium-rare, 35 to 45 minutes. Transfer to a cutting board; let rest for 5 minutes. Remove the string. Slice and serve with Creamy Horseradish Sauce.
