01 - Pat the beef roast dry with paper towels and season all sides generously with kosher salt and freshly ground black pepper.
02 - Heat olive oil in a large skillet over medium-high heat. Sear the roast for 3 to 4 minutes per side until a deep brown crust forms on all surfaces.
03 - Arrange carrots, baby potatoes, onion wedges, minced garlic, and celery pieces in an even layer at the bottom of the slow cooker.
04 - Transfer the seared roast and place it directly on top of the vegetable bed.
05 - Pour the beef broth and Worcestershire sauce evenly over the roast and surrounding vegetables.
06 - Tuck the rosemary sprigs, thyme sprigs, and bay leaves into the liquid around the meat.
07 - Cover and cook on low setting for 8 hours until the beef pulls apart easily with a fork and vegetables are completely tender.
08 - Remove and discard the herb sprigs and bay leaves. Slice or shred the roast and serve alongside the vegetables with pan juices spooned over the top.
