Pat the beef chuck dry with paper towels and season with sea salt and black pepper.
Heat the olive oil in a Dutch oven over medium-high heat. Sear the beef until browned on all sides, then remove and set aside.
Lower the heat to medium and add the diced onion, celery, and minced garlic. Sauté for 3-4 minutes until the onion is translucent.
Stir in the tomato paste, dried thyme, and dried rosemary, cooking for 1 minute to wake up the spices.
Pour in the beef bone broth and use a wooden spoon to scrape up any browned bits from the bottom of the pot.
Add the beef back into the pot along with the sliced carrots and parsnips.
Bring the liquid to a boil, then reduce heat to low, cover with a tight-fitting lid, and simmer for 60-90 minutes until the beef is fork-tender.
Serve hot in a shallow bowl, ensuring a generous portion of the root vegetables and savory broth.
