Pat the beef chuck roast dry with paper towels and season evenly with sea salt and black pepper.
Heat the olive oil in a heavy-bottomed pot or Dutch oven over medium-high heat.
Sear the beef until a deep golden-brown crust forms on all sides, then remove the meat and set it aside.
Lower the heat to medium and add the diced onion, carrots, and minced garlic, sautéing until the vegetables are softened and fragrant.
Stir in the tomato paste and cook for one minute to caramelize the sugars and deepen the flavor.
Pour in the red wine to deglaze the pot, using a wooden spoon to scrape up all the flavorful browned bits from the bottom.
Return the beef to the pot and pour in the beef broth until the meat is partially submerged.
Add the fresh thyme sprig, cover with a tight-fitting lid, and simmer on low heat for 90 minutes or until the beef is fork-tender.
