Preheat the oven to 300°F and begin generously seasoning the roast with salt and pepper on both sides.
Heat olive oil in a pan on medium-high heat.
Add the roast to the pan, searing each side for 5 minutes.
While the roast is searing, chop onions and mince the garlic.
Add half of the potatoes, carrots, and onion to the bottom of your Dutch oven.
Once the roast is seared, remove it from the pan and place in the center of your Dutch oven.
Add the remaining potatoes, carrots, and onion around the roast in the Dutch oven.
On medium-high heat, add the 1 cup of the beef stock to the pan and begin deglazing the pan.
Add the garlic, tomato paste, and Worcestershire sauce to the broth mixture continuing to stir until smooth.
Pour the remaining beef broth into the pan and add the fresh thyme and rosemary sprigs. Mix well.
Pour this mixture over the roast and vegetables in the Dutch oven.
Cover the Dutch oven and place into the oven.
Bake for 3.5 hours or until tender.
Allow the roast to cool before slicing or using a fork to shred the roast.
Serve warm.
