I think it’s fair to say that the star of this show is the marrow. Our 100% grass-fed osso buco is a beef shank that is cooked with bone in the middle. As it cooks, the bone marrow releases to make a rich flavorful broth that is essential to the finished meal. We're talking maximum collagen which leads to maximum goodness! It's a delicious dish, and something that everyone should try at least once!
