Instructions:
1. Season the beef chuck roast with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Sear the roast on all sides until browned, about 4-5 minutes per side.
2. Transfer the seared roast to a slow cooker. Add the sliced onions and garlic around the roast.
3. In a small bowl, mix together the beef broth, Worcestershire sauce, and tomato paste. Pour this mixture over the roast and onions.
4. Add the potato chunks to the slow cooker, arranging them around the roast.
5. Sprinkle the dried thyme and rosemary over the top.
6. Cover and cook on low for 7-8 hours, or until the beef is tender and the potatoes are cooked through.
