Juicy herbed beef tenderloin tastes delicious when accompanied by Creamy Horseradish Sauce. English cucumber adds an unexpected crunch to the sauce. Have a small bowl of horseradish available for guests who enjoy an extra hit of pungent heat.
Preheat oven to 500°. Combine first 6 ingredients in a small bowl; rub mixture over beef. Place beef in a large pan.
Bake at 500° for 10 minutes. Reduce oven temperature to 350°. Bake for 30 more minutes or until a meat thermometer registers 140° or until desired degree of doneness. Remove from oven, and cool until room temperature (1 hour).
Meanwhile, prepare Creamy Horseradish Sauce.
Wrap beef in plastic wrap; chill overnight. Cut roast into 1/2-inch slices; arrange slices on a serving platter. Garnish, if desired. Serve with Creamy Horseradish Sauce.
