Season the beef roast with salt and pepper.
Heat a skillet over medium-high heat and sear the roast on all sides until browned.
Place chopped carrots, potatoes, and onion in the bottom of the crockpot.
Add minced garlic on top of the vegetables.
Pour beef broth and red wine over the roast.
Add Worcestershire sauce and thyme.
Cover and cook on low for 8 hours or high for 4 hours.
Check the roast for tenderness; it should easily shred with a fork.
Remove the roast and let it rest for 10 minutes before slicing.
Serve with the vegetables and broth, garnished with fresh parsley.
