SAUCE FOR TENDERLOIN ROAST RECIPES

Steps:

• Preheat oven to 400 degrees F. Coat a large rimmed baking sheet with cooking spray.
• Tie kitchen string around beef in 4 places. Season with 1 teaspoon salt and 1/2 teaspoon pepper.
• Heat 1 teaspoon oil in a large skillet over medium-high heat. Add the beef and cook, turning occasionally, until browned on all sides, 6 to 8 minutes. Transfer to the prepared pan.
• Roast the beef until an instant-read thermometer inserted in the thickest part registers 130 degrees F for medium-rare, 35 to 40 minutes. Let rest 10 minutes before slicing.
• Meanwhile, heat the remaining 2 teaspoons oil in the skillet over medium-high heat. Add shallot and cook for 30 seconds. Stir in mushrooms and the remaining 1/2 teaspoon salt and 1/4 teaspoon pepper; cook, stirring occasionally and scraping up any browned bits, until the mushrooms are lightly browned, 3 to 5 minutes. Pour in wine, bring to a boil and cook until nearly evaporated, about 3 minutes. Stir in broth, return to a boil and cook until reduced by a third, 3 to 5 minutes. Remove from heat, add butter and swirl until melted.
• Remove the string and slice the beef. Serve with the mushroom sauce.

Steps:

• Preheat oven to 425°. In a small bowl, combine the mustard, garlic, pepper, garlic salt and onion salt; brush over tenderloin. Place in a shallow roasting pan. Bake, uncovered, until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°), 45 minutes., Remove tenderloin from pan; let stand for 10-15 minutes before slicing. Meanwhile, add broth to pan drippings, stirring to loosen browned bits; heat through. Serve with sliced beef.
