Preheat the oven to 375 degrees F.
Chop 4 carrots, 4 parsnips, 2 onions and 4 beets uniformly, so they roast evenly. Spread root vegetables in a single layer on a baking sheet, coat with 3 tablespoons extra-virgin olive oil, and add garlic, sea salt, and ground pepper. Mix. Roast in oven for 45 minutes. Heat 3 tablespoons olive oil in a large pan on medium-high. Lightly toss the beef cubes in flour and add to pan. Sear for a few minutes on all sides until meat has a crisp exterior. Deglaze the pan with red wine. Transfer the beef and juices into a big pot and add the halved carrot, organic beef stock, halved celery stalk, fresh parsley, bones (from the fore shank), bay leaves, thyme, and peppercorns. Cover and simmer for 2 hours, check on stew occasionally, remove the scum from the surface of the stew. Remove and discard the soggy carrot halves, celery, bones, and herbs. Add the roasted vegetables, red lentils, and pinch brown sugar and let simmer an additional 20 minutes. Serve the stew in bowls topped with fresh, minced parsley.
