Juicy, citrus-marinated skirt steak grilled to perfection and tucked into warm corn tortillas with fresh onion, cilantro, avocado, and a sprinkle of cotija. Weeknight-easy, party-perfect.
Whisk orange juice, lime juice, soy sauce, olive oil, garlic, cilantro (for marinade), cumin, chili powder, black pepper, salt, and minced jalapeño in a large bowl.
Add skirt steak and turn to coat. Cover and marinate in the refrigerator for at least 30 minutes and up to 8 hours.
Preheat a grill or cast-iron skillet over high heat. Lightly oil the grates or pan.
Remove steak from marinade, letting excess drip off, and pat dry. Grill over high heat for 3 to 5 minutes per side for medium-rare (130 to 135°F).
Rest steak on a board for 5 minutes, then slice thinly against the grain.
Warm tortillas on the grill or in a dry skillet until pliable. Keep warm in a clean towel.
Assemble tacos: layer sliced carne asada into tortillas and top with onion, cilantro, avocado, and cotija. Squeeze lime over the top and serve immediately.
Notes
For extra char, finish steak directly over high heat for the final minute per side. Swap skirt steak for flank if needed. Adjust heat by keeping or removing jalapeño seeds.
