Tacos de Lengua are a beloved Mexican street food featuring tender, slow-braised beef tongue, typically served on small corn tortillas and topped with fresh cilantro, onions, and a squeeze of lime. The tongue is usually simmered for hours in a flavorful broth with aromatics like onion, garlic, and bay leaves until it becomes incredibly soft and succulent.
This dish is a high-protein, relatively low-carb option, with the beef tongue providing a rich source of iron, zinc, and B vitamins, especially B12. A typical serving of two tacos generally falls in the range of 350-450 calories, depending on the cut of meat and added toppings.
