Lengua tacos are a beloved Mexican street food featuring slow-braised beef tongue, typically served on small corn tortillas and garnished with fresh cilantro, diced onion, 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 tender and rich. This dish is a staple in taquerías across Mexico and among Mexican-American communities.
Lengua tacos are high in protein and provide a good source of iron, zinc, and B vitamins, particularly B12. A typical serving of two tacos contains roughly 300-400 calories, with a moderate amount of fat from the meat and a small amount of carbohydrates from the corn tortillas.
