Preheat the oven to 325°.
Add the flour to a bowl or a plate and season it very well with salt and pepper, about 1 tablespoon of salt and 1/2 teaspoon of pepper.
Dredge the veal shanks on all sides in the flour and set them aside. Next, heat the olive oil in a Dutch oven over medium-high heat and heat until it begins to smoke lightly.
Mix in the tomato paste and cook for two minutes. Add the tomatoes and deglaze with the wine. Cook for 2 minutes. Place in the beef stock, bay leaves, parsley, thyme, salt, and pepper.
