  2. In a slow cooker place the beef roast, caramelized onion, and garlic.
  3. Add the balsamic vinegar, beef broth, worcestershire sauce, salt, pepper and fresh thyme.
  4. Cook on high for 4-6 hours or on low for 8-10 hours.
  5. Note: the onions can be caramelized the day before and stored in the refrigerator until ready to add to the slow cooker.
