Broiled Sirloin Recipe

With a meat fork, pierce holes in both sides of steak. Place in a shallow glass container or large resealable bag. Combine onion, lemon juice, oil, garlic salt, thyme, oregano, celery salt and pepper; pour over meat. Cover and refrigerate for 6 hours or overnight. Discard marinade. Place steak on broiler pan. Broil 6 in. from the heat for 8 min. Brush with butter and turn. Broil 6 minutes longer or until meat reaches desired doneness (for rare, a meat thermometer should read 140 degrees; medium, 160 degrees; well-done, 170 degrees)
