Preparation:   

Preparation time: 40 mins

Cooking time: 1 hrs 30 mins

Serving: 6

Ingredients:

• 1 beef sirloin tip roast or beef tri-tip roast (2 to 3 pounds)
• 1 tablespoon kosher salt
• 2 teaspoons dried thyme
• 2 teaspoons garlic powder
• 1 teaspoon coarsely ground pepper
• 2 tablespoons olive oil, divided
• 1 small onion, chopped
• 1 bottle (750 milliliters) dry red wine
• 6 fresh thyme sprigs
• 1 garlic cloves, crushed
• 1/2 teaspoon whole peppercorns
• 3 whole cloves

  Horseradish-thyme butter (optional)

• 6 tablespoons softened butter
• 2 tablespoons prepared horseradish
• 3 tablespoons fresh thyme leaves

Instructions:

1. Sprinkle roast with salt, thyme, garlic powder and ground pepper. Cover and refrigerate at least 8 hours or up to 24 hours. Meanwhile, in a saucepan, saute onion in 1 tablespoon oil until tender, about 5 minutes. Add wine, thyme, garlic, peppercorns and cloves. Simmer until reduced to 3/4 cup. Cool; strain, discarding solids, and refrigerate.
2. Remove roast from the refrigerator 1 hour before grilling. Prepare grill for indirect heat, using a drip pan. Add wood chips according to manufacturer's directions.
3. Pat roast dry with paper towels. Brush with remaining 1 tablespoon oil; place over drip pan. Grill, covered, over medium-low indirect heat, brushing with mop sauce every 20 minutes, until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°), 1-1/2 to 2 hours. Let stand 15 minutes before slicing.
4. If desired, in a small bowl, stir together butter, horseradish and thyme. Serve on top of roast.
