Steamed tacos filled with beans, potato, or chicharrón, softened in a bath of warm oil. These budget-friendly family tacos are a beloved Mexico City breakfast street food tradition.
Warm the corn tortillas on a skillet over medium heat just until pliable, about 30 seconds each side, and keep them covered to prevent drying.
Prepare three separate fillings: spread about 2 tablespoons of refried beans on one third of the tortillas, mashed potatoes on another third, and crumbled chicharrón mixed with some chopped onions on the final third.
Fold tortillas in half, pressing gently to seal the fillings, and stack the filled tacos in a deep bowl lined with parchment paper.
Heat the vegetable oil in a pan over medium-low. Stir in guajillo chili powder, salt, and black pepper, and cook for 1 minute until aromatic, then pour this seasoned oil evenly over the stacked tacos.
Cover the bowl tightly (using foil or a lid), then let the tacos steam in their own heat for 30–40 minutes. This step allows the flavors to meld and the tortillas to achieve the signature soft, moist texture.
Serve hot and enjoy with salsa or pickled chilies if desired.
