Season & sear: Season the roast generously with salt and pepper. Sear on all sides in a little avocado oil over high heat until deeply browned. Remove the roast and lower the heat.
Build flavor: Add the tomato paste and cook, stirring often, until darkened and fragrant.
Deglaze: Pour in the wine and scrape up all the browned bits from the bottom of the pot.
Braise: Add the bay leaves, thyme, and garlic. Return the roast to the Dutch oven, then pour in the broth and Worcestershire.
Cook low and slow: Cover and transfer to a 275°F oven. Cook for 2 hours.
Add vegetables: Remove the lid, add the vegetables and potatoes, then cover and return to the oven. Cook for another 2 hours, or until the beef is fall-apart tender.
Serve: Shred the roast and serve with the vegetables, spooning the braising liquid over the top.
Notes
Strain and reduce the braising liquid for 10-15 minutes to create an even richer sauce for drizzling.
