01 - Preheat the oven to 325°F (165°C).
02 - Pat the beef roast dry and season all sides evenly with kosher salt and black pepper.
03 - Heat olive oil in a large Dutch oven over medium-high heat. Sear the beef on all sides until deeply browned, approximately 3 to 4 minutes per side. Remove and set aside.
04 - Add onions and carrots to the pot and sauté for 3 to 4 minutes, scraping up browned bits. Add minced garlic and cook for an additional minute.
05 - Stir in tomato paste and cook for one minute. Pour in red wine, scraping the bottom to release any remaining browned bits.
06 - Return the beef to the pot. Add quartered potatoes, beef broth, Worcestershire sauce, bay leaves, and thyme. Bring the mixture to a simmer.
07 - Cover the pot and transfer to the preheated oven. Braise for 2.5 to 3 hours until beef is fork-tender and vegetables are cooked through.
08 - Remove the beef and vegetables to a serving platter. Discard the bay leaves and thyme stems.
09 - Skim excess fat from the braising liquid. In a small bowl, combine cornstarch and cold water to create a slurry. Bring the liquid to a simmer on the stovetop and whisk in the slurry. Cook 2 to 3 minutes until thickened.
10 - Slice or shred the beef and serve alongside the vegetables, drizzled with the prepared gravy.
