Lamb Osso Buco is a rich, slow-braised Italian dish featuring cross-cut lamb shanks, where the marrow-filled bone becomes a centerpiece of flavor. It's typically simmered in a savory broth with aromatic vegetables like onions, carrots, and celery, along with tomatoes, white wine, and herbs such as rosemary and thyme. The dish originates from Milan in the Lombardy region of Northern Italy.
This dish is very high in protein and fat, with minimal carbohydrates, making it a hearty and satiating meal. A typical serving provides significant iron, zinc, and collagen from the bone and connective tissue, with a calorie count roughly between 400-600 per serving depending on the cut and preparation.

Culturally, the name 'osso buco' means 'bone with a hole' in Italian, referring to the prized marrow cavity that is traditionally scooped out and enjoyed as a delicacy. Nutritionally, the long braising process breaks down tough collagen into gelatin, which is beneficial for gut and joint health, and the marrow itself is a dense source of healthy fats and minerals.
