How to Make Beef Tenderloin Sliders with Horseradish Sauce

Preheat the oven to 475°F. Tie the roast in 1 1/2-inch intervals if necessary and place in a large roasting pan. Season with salt and pepper. Cook the beef for 15 minutes. Pour the butter over the beef and continue roasting until it reaches an internal temperature of 130°F for medium rare, 25 to 30 minutes. (The temperature will rise 5 to 10 degrees while resting.)
