Season the beef chuck roast on all sides with sea salt and black pepper.
Heat 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 and set aside.
Add the chopped onion, carrots, and parsnips to the pot, sautéing until the onions are translucent.
Stir in the minced garlic, dried rosemary, and dried thyme, cooking for one minute until fragrant.
Return the beef to the pot and pour in the beef bone broth, adding the bay leaf.
Cover and simmer on low heat for 2 to 3 hours until the beef is fork-tender and the vegetables are soft.
Remove the bay leaf before serving the roast and vegetables with the concentrated pan juices.
