Heat the olive oil in a heavy-bottomed pot or Dutch oven over medium-high heat.
Add the lean beef stew meat and sear until browned on all sides, then remove the beef and set it aside.
In the same pot, add the diced onion, carrots, and parsnips, sautéing for 5 minutes until the onion is translucent.
Add the minced garlic and dried thyme, stirring for 1 minute until fragrant.
Return the beef to the pot and stir in the tomato puree, sea salt, and black pepper.
Pour in the beef bone broth and bring the mixture to a gentle boil.
Reduce the heat to low, cover the pot, and simmer for 45 to 60 minutes until the beef and root vegetables are fork-tender.
Serve hot in a deep bowl, ensuring a generous portion of broth and vegetables in every serving.
