Preheat your oven to 325°F.
Cook the diced pancetta in a large, ovenproof pot over medium heat until it turns crispy.
Remove it and leave about two tablespoons of fat in the pot.
Season the veal shanks with salt and pepper.
Brown them in the pot in batches and set them aside.
This enhances the flavor of the meat and helps create a more robust sauce.
Add diced tomatoes (with juice), chicken broth, rosemary, thyme, bay leaf, and cloves to the pot.
Combine the ingredients thoroughly to ensure even seasoning.
Nestle the browned veal shanks back into the liquid.
Cover the pot securely with a lid to maintain a steady temperature.
Transfer the pot to the preheated oven and let the osso buco braise for 1 ½ to 2 hours.
Serve with risotto or mashed potatoes for a complete meal.
