Method

  • Preheat the oven to 375.
  • Season the veal shanks with salt and pepper.
  • In a very large, deep skillet, heat 3 tablespoons of the olive oil until shimmering.
  • Working in batches, cook the veal over moderately high heat until browned on both sides, about 8 minutes total per batch.
  • Transfer the osso buco to a large roasting pan.
  • Add the remaining 3 tablespoons of olive oil to the skillet.
  • Add the diced carrots, celery, onions, 4 whole garlic cloves and the bay leaves and cook over moderate heat until they are softened, about 12 minutes.
  • Add the chicken stock, white wine, diced tomatoes and thyme sprigs and bring to a boil.
  • Pour the vegetables and liquid over the veal, cover the roasting pan with foil and transfer to the oven.
  • Braise the shanks for about 2 1/2 hours, until very tender.
  • Meanwhile, in a small bowl, mix the orange zest, lemon zest, parsley and the 2 minced garlic cloves.
  • Lightly season the gremolata with salt and pepper.
  • Transfer the veal shanks to a baking sheet and cover with foil.
  • Carefully strain the cooking liquid into a large bowl.
  • Reserve the vegetables; discard the bay leaves and thyme sprigs.
  • Pour the cooking liquid back into the roasting pan and boil over high heat until it is reduced by half, about 25 minutes.
  • Season the sauce with salt and pepper.
  • Stir in the reserved vegetables and simmer over moderately low heat for 2 minutes.
  • Transfer the osso buco to shallow bowls.
  • Spoon the sauce and vegetables on top and sprinkle lightly with the gremolata.
  • Serve with the remaining gremolata at the table.
