Instructions
Season the meat
1
Combine cumin, smoked paprika, garlic powder, oregano, 1 tsp kosher salt, and ½ tsp black pepper. Coat the steak on all sides. Let sit at room temperature for 15 minutes to allow the spices to bloom and adhere.
Prep your toppings
2
Dice onion very fine (2–3mm pieces), chop cilantro (leaves and tender stems), and cut limes. Set everything in small bowls ready to go — street taco assembly is fast.
Cook the meat
3
Heat a cast iron skillet or griddle over high heat until smoking hot. Add oil. Cook skirt steak 3–4 minutes per side without moving. You want deep, charred color and sizzling contact with the surface.
Char the tortillas
4
Place corn tortillas directly on a gas flame or in a dry cast iron skillet over high heat. 20–30 seconds per side until pliable with char spots. Double-stack them immediately.
Assemble and serve
5
Layer meat in the center of doubled tortillas, top with white onion and cilantro, squeeze fresh lime over everything, and finish with salsa verde. Serve while the tortillas are still warm.
