People don’t talk about oxtail stew these days, but it’s a true Primal-worthy classic. With an arguably richer taste than beef and more succulent feel when cooked for stew or soup, oxtail might just become a new favorite. But the real difference (and reason behind the appealing stewed texture) is the ample connective tissue—an incredible source of collagen for the benefit of skin, hair, joint health, performance and more. (Since we used bone broth here in lieu of water or regular stock, this recipe is one of the best you can make for collagen content.) You’ll enjoy warming up with this gelatinous, flavorful and hearty dish on a late winter night. And you might consider making an extra batch: it tastes even better the next day.
