01 - Pat the beef roast completely dry with paper towels. Season generously on all sides with salt and pepper.
02 - Heat a large skillet over medium-high heat. Sear the roast on all sides until deeply browned, approximately 2-3 minutes per side. Transfer the seared beef to the slow cooker.
03 - Place carrots, parsnips, potatoes, onion, and celery around and beneath the beef in the slow cooker insert.
04 - In a medium bowl, whisk together beef broth, red wine, tomato paste, Worcestershire sauce, thyme, rosemary, and minced garlic until well combined.
05 - Pour the liquid mixture evenly over the beef and vegetables. Tuck bay leaves into the liquid.
06 - Cover and cook on LOW setting for 8 hours, or until beef shreds easily with a fork and vegetables are tender.
07 - Discard bay leaves from the cooking liquid.
08 - Transfer the roast and vegetables to a large serving platter. Skim excess fat from cooking liquid if desired, and spoon some over the meat and vegetables. Garnish with fresh parsley.
