Grill meat on high and brown each side for about 10 minutes. Place beef broth, red wine, garlic, sugar, molasses, and herbs in roasting pan on stovetop with burner on high heat. Bring to a boil for one or two minutes until sugar dissolves. Add browned meat. Add potatoes, carrots, parsnips, and onions. Liquid in pot should be about halfway up the sides of the meat. If there's not enough liquid, add more beef broth and wine. Cover pan with a tight-fitting lid or wrap tightly with aluminum foil. Bake in oven at 325 degrees for at least 4 hours. When done, meat should fall apart with a fork.
