Make tender, flavorful carne asada for your next gathering. This recipe focuses on a simple citrus and soy marinade and proper slicing technique for the best street tacos.

Ingredients

Scale
  • 2 lbs flank steak or skirt steak
  • 1/2 cup fresh lime juice
  • 1/4 cup soy sauce
  • 1/4 cup orange juice
  • 2 tablespoons olive oil
  • 4 cloves garlic, minced
  • 1 teaspoon ground cumin
  • 1 teaspoon dried oregano
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt
  • 24 small corn tortillas
  • 1 cup diced white onion
  • 1 cup chopped fresh cilantro
  • Lime wedges, for serving

Instructions

  1. Combine lime juice, soy sauce, orange juice, olive oil, minced garlic, cumin, oregano, pepper, and salt in a bowl to make the marinade.
  2. Place the flank or skirt steak in a large, resealable plastic bag or shallow dish. Pour the marinade over the steak, ensuring it is fully coated.
  3. Refrigerate the steak for at least 4 hours, or preferably overnight, to absorb the authentic carne asada marinade flavor.
  4. Remove the steak from the marinade and discard the liquid. Pat the steak dry with paper towels.
  5. Grill the steak over high heat for 4 to 6 minutes per side for medium-rare, depending on thickness. The goal is to get good char on the outside.
  6. Remove the steak from the grill and let it rest on a cutting board for 10 minutes before slicing. This resting period is key for tenderness.
  7. Slice the steak thinly against the grain for your flank steak tacos recipe.
  8. Warm the corn tortillas on a dry skillet or griddle until soft and pliable.
  9. Assemble your Mexican street tacos aesthetic by filling each tortilla with sliced carne asada, diced onion, and cilantro. Serve immediately with lime wedges.

Notes

  • For the best texture, always slice skirt steak or flank steak thinly across the muscle fibers (against the grain). This is how to cut skirt steak for tacos to ensure maximum tenderness.
  • If you do not have a grill, you can cook the steak in a very hot cast-iron skillet until properly seared.
  • To feed a large crowd efficiently, cook the steak in batches and keep the sliced meat warm in a low oven (200°F) while you finish grilling.
