Pat the chuck roast dry and season all sides with sea salt and black pepper.
Heat olive oil in a large pot or Dutch oven over medium-high heat.
Sear the beef for 4-5 minutes per side until a deep brown crust forms, then remove and set aside.
Add sliced onions and chopped carrots to the pot, sautéing for 5 minutes until slightly softened.
Stir in minced garlic and grated ginger, cooking for 1 minute until fragrant.
Pour in the beef broth and add dried thyme, scraping the bottom of the pot to release any browned bits.
Return the beef to the pot, cover with a tight-fitting lid, and reduce heat to low.
Simmer for 2 to 3 hours until the beef is fork-tender and easily shreds.
Shred the beef with two forks and serve hot with the tender root vegetables and savory pan juices.
