HORSERADISH CREAM SAUCE FOR BEEF TENDERLOIN RECIPES

Steps:

• Put oven rack in middle position and preheat oven to 400°F.
• Cut off and discard top fourth of garlic head. Drizzle exposed garlic with oil and sprinkle with 1/4 teaspoon salt, then wrap head tightly in foil. Roast garlic until tender, about 1 1/4 hours, then open foil and cool.
• While garlic roasts, simmer cream in a 1 1/2- to 2-quart heavy saucepan, stirring occasionally, until reduced to about 3/4 cup, 20 to 25 minutes, then transfer to a bowl.
• Squeeze garlic into a small bowl, discarding skins, and mash together with horseradish, pepper, and remaining 1/2 teaspoon salt using a fork.
• Stir garlic mixture into cream, then chill until ready to use.
• Increase oven temperature to 475°F.
• Pat tenderloin dry. Stir together pepper, bouillon, salt, cornstarch, oregano, garlic powder, and paprika in a small bowl. Rub oil all over tenderloin, then sprinkle with spice mixture, rubbing it into meat. Put tenderloin on rack in roasting pan and roast 10 minutes, then reduce oven temperature to 425°F and cook until thermometer inserted diagonally into center of meat registers 130°F, 20 to 25 minutes for medium-rare. Let beef stand on rack in pan 10 minutes before serving.
• Cut beef into 1/4-inch-thick slices and serve with garlic horseradish cream.

Steps:

• Whisk crème fraîche (or sour cream) in a medium bowl until thickened and soft peaks start to form, 1-2 minutes. Fold in horseradish and peppercorns; season with salt and more horseradish, if desired. DO AHEAD Sauce can be made 3 days ahead. Cover; chill.
• Combine first 5 ingredients and rub all over meat, pressing to adhere. DO AHEAD Beef can be seasoned 1 day ahead. Wrap in plastic; chill. Let stand at room temperature for 1 hour before continuing.
• Preheat oven to 400°. Scatter rosemary over bottom of a large roasting pan.
• Heat oil and butter in a 12 inches cast-iron skillet over medium-high heat. Sear meat until brown on all sides, about 5 minutes. Transfer to prepared roasting pan.
• Roast meat until an instant-read thermometer inserted into thickest part of beef registers 125° for medium-rare, about 30 minutes. Transfer to a carving board. Let rest for 15 minutes. Thinly slice tenderloin. Serve with Horseradish Cream.
• To double or triple the recipe, sear the tenderloins one at a time, then arrange crosswise in roasting pan (cook time will be the same). Leave at least 1 inch-2 inches between pieces of meat.
