INGREDIENTS:

• 1 beef Sirloin Tip Roast Boneless (2 to 2-1/2 pounds)
• 1 tablespoon minced fresh parsley
• 1 teaspoon dried thyme leaves, crushed
• 1 teaspoon vegetable oil
• 1 teaspoon minced garlic
• 1/2 teaspoon cracked black pepper

• 1 cup dairy sour cream
• 1/2 cup prepared horseradish
• 2 tablespoons milk
• 1 tablespoon snipped fresh chives
• 1/8 teaspoon ground white pepper

COOKING:

1. Preheat oven to 325°F. Combine parsley, thyme, oil, garlic and black pepper; press evenly onto all surfaces of beef Roast.
2. Place roast on rack in shallow roasting pan. Insert ovenproof meat thermometer so tip is centered in thickest part of beef. Do not add water or cover. Roast in 325°F oven 1-1/4 to 1-1/2 hours for medium rare doneness.
3. Meanwhile combine sauce ingredients in small bowl; cover and refrigerate.
4. Remove roast when meat thermometer registers 135°F for medium rare. (Do not overcook.) Transfer roast to carving board; tent loosely with aluminum foil. Let stand 10 to 20 minutes. (Temperature will continue to rise about 10°F to reach 145°F for medium rare.) Carve roast into thin slices; season with salt, as desired. Serve with sauce.
