Pat the roast dry with paper towels and season generously with salt and pepper on all sides.
Mix together thyme, rosemary, and minced garlic, then press the herb mixture firmly into all sides of the roast.
Heat olive oil in a large skillet over medium-high heat and sear the roast for 3-4 minutes per side until browned.
Transfer the roast to the slow cooker and pour beef broth and Worcestershire sauce around it.
Cover and cook on low for 8 hours or high for 4-5 hours until the meat is fork-tender.
Remove roast from slow cooker, let rest for 10 minutes, then slice and serve with the pan juices.
