Ingredients:

- 4-6 veal shanks, 1 1/2 to 2 inches thick
- 1/2 cup all-purpose flour
- Salt and black pepper, to taste
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1 onion, chopped
- 2 carrots, chopped
- 2 celery stalks, chopped
- 3 garlic cloves, minced
- 1 tablespoon tomato paste
- 1 1/2 cups beef or chicken stock
- 1/2 cup dry white wine
- 1 bay leaf
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- Grated lemon zest, for garnish (optional)
- Chopped parsley, for garnish (optional)
Instructions:
- Preheat the oven to 325°F (165°C).
- In a shallow dish, combine the flour with salt and black pepper to taste.
- Dredge the veal shanks in the flour mixture, shaking off any excess.
- In a large Dutch oven or heavy pot, melt the butter and olive oil over medium-high heat.
- Brown the veal shanks on all sides until nicely browned, about 8-10 minutes. Remove the shanks from the pot and set them aside.
- Add the onion, carrots, celery, and garlic to the pot and sauté until softened, about 5 minutes.
- Stir in the tomato paste and cook for another minute.
- Add the beef or chicken stock, white wine, bay leaf, thyme, and rosemary to the pot and stir to combine.
- Return the veal shanks to the pot, making sure they are submerged in the liquid.
- Cover the pot with a lid and transfer it to the preheated oven.
- Bake for 2 1/2 to 3 hours, or until the meat is very tender and falling off the bone.
- Remove the pot from the oven and discard the bay leaf.
- Serve the Osso Buco hot, garnished with grated lemon zest and chopped parsley, if desired.
Enjoy your delicious Osso Buco!
