Serves 8 This recipe has minimal preparation. Marinading roast prior to grilling will aid in tenderness, and is perfect for the great outdoors on a summer night. INSTRUCTIONS: Pierce the sirloin tip or top round roast with a fine-tipped fork. Place in marinade of your choice & let rest 1 hr. at room temperature. Refrigerate up to 48 hours. Remove from marinade, and pat excess marinade off with a paper towel. Let rest at room temperature 2 hours before grilling or roasting. Sear all sides of roast over hot coals or medium high gas flame—about four turns at 5 minutes each. Move roast to medium heat and cover grill. Continue grilling, for 20+ minutes, turning once for medium rare. Internal temperature should read 135°. Remove from oven and place on platter. Cover with foil and allow roast to rest for 5 to 10 minutes. Slice thinly against the grain. Temperature Guide—Internal temperatures of meat: Rare – 130 degrees. Medium-rare – 140 degrees. Medium – 155 degrees.
