Season the roast with salt and pepper on all sides.
Heat a skillet over medium-high heat and sear the roast until browned on all sides.
Transfer the roast to the crockpot.
Add chopped carrots, potatoes, onion, and garlic around the roast.
In a bowl, mix together beef broth, Worcestershire sauce, and thyme.
Pour the broth mixture over the roast and vegetables.
Cover and set the crockpot to low for 8 hours or high for 4 hours.
Check for doneness; the meat should be fork-tender.
Once cooked, remove the roast and let it rest for 10 minutes before slicing.
Serve with the cooked vegetables, garnished with fresh herbs.
