Pat the beef chuck roast dry with paper towels and season all sides 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 for 3-4 minutes per side until a deep golden-brown crust forms, then remove the beef and set it aside.
Add the chopped onion, carrots, and celery to the same pot, sautéing for 5 minutes until the onions are translucent.
Stir in the minced garlic, dried rosemary, and dried thyme, cooking for 1 minute until fragrant.
Pour in the beef bone broth, using a wooden spoon to scrape up any browned bits from the bottom of the pot.
Return the beef to the pot, cover with a tight-fitting lid, and reduce heat to low.
Simmer for 2.5 to 3 hours, or until the beef is fork-tender and the vegetables are soft.
Transfer the beef to a plate to rest for 5 minutes before slicing and serving with the braised vegetables and pan juices.
