01 - Preheat oven to 325°F.
02 - Pat the chuck roast dry with paper towels and season all sides generously with kosher salt and black pepper.
03 - In a large Dutch oven or heavy ovenproof pot, heat olive oil over medium-high heat. Sear the roast on all sides until deeply browned, about 3 to 4 minutes per side. Remove the roast and set aside.
04 - In the same pot, add the sliced onions, carrot pieces, and celery. Sauté for 5 minutes until slightly softened. Add the smashed garlic and tomato paste, stirring and cooking for 1 minute until fragrant.
05 - Pour in the dry red wine to deglaze, scraping up all the browned bits from the bottom of the pot. Let the wine reduce by half, about 2 to 3 minutes.
06 - Return the seared roast to the pot. Arrange the quartered potatoes around the meat, then tuck in the dried thyme, rosemary, and bay leaves. Pour in the beef broth until it reaches halfway up the sides of the roast.
07 - Bring the liquid to a gentle simmer on the stovetop, then cover tightly with the lid and transfer the pot to the preheated oven.
08 - Bake for 2.5 to 3 hours, or until the roast is fork-tender and pulls apart easily.
09 - Remove the roast and vegetables from the pot. Discard the bay leaves. Skim excess fat from the pan juices if desired. Slice or shred the beef and serve alongside the vegetables, spooning pan juices generously over each portion.
