Place the halved baby gold potatoes in an even layer at the bottom of the slow cooker.
Arrange the beef cubes over the top of the potatoes.
In a small mixing bowl, whisk together the beef broth, minced garlic, Worcestershire sauce, dried thyme, dried rosemary, salt, and black pepper.
Pour the liquid mixture evenly over the beef and potatoes.
Distribute the butter cubes across the top of the beef.
Cover and cook on low setting for 6 to 8 hours or on high setting for 3 to 4 hours until the beef is fork-tender.
Garnish with fresh parsley before serving.
