Korean Steak Tacos

This vibrant high-protein recipe for Korean steak tacos brings together bold, savoury flavours and fresh textures. The flank steak is marinated in a punchy blend of soy, ginger and toasted sesame oil, resulting in deeply caramelised meat that pairs perfectly with a crisp cabbage and carrot slaw. It is an excellent choice for those looking for a balanced, nutritious meal that feels like a weekend treat while remaining packed with lean protein and fresh vegetables.

Perfect for a casual dinner party or a family mid-week meal, these tacos are designed for sharing. By serving the components separately, everyone can customise their own tortilla with the tender sliced beef, zesty slaw and a dollop of creamy guacamole. Using corn tortillas keeps the dish gluten-free and light, making it a versatile addition to your homemade repertoire.

Ingredients for Korean Steak Tacos

  • 1/2 cup finely chopped fresh coriander

  • 1/4 cup packed dark brown sugar

  • 45ml canola oil

  • 45ml soy sauce

  • 1 tablespoon toasted sesame oil

  • 2 large garlic cloves, minced

  • 1 jalapeño pepper, seeded and finely chopped

  • 1 teaspoon freshly ground black pepper

  • 1 teaspoon ground coriander

  • One 900g flank steak (about 1 1/2 inches thick), fat trimmed

  • 1/2 head napa cabbage, halved lengthwise and shredded crosswise (about 725ml )

  • 1 large carrot, cut into 2-inch-long matchstick-size strips

  • 8 spring onions (white and green parts), thinly sliced on a sharp diagonal

  • 1/2 cup lightly packed fresh coriander sprigs

  • Twelve 6-inch corn tortillas

  • Guacamole for Lindsay

  1. To marinate the steak: In a large baking dish, whisk the coriander, brown sugar, canola oil, soy sauce, sesame oil, garlic, jalapeños, black pepper, and coriander to blend well. Reserve 60ml the mixture in a small bowl for serving. Place the steak in the remaining marinade and turn to coat. Marinate for at least 20 minutes at room temperature, or cover and refrigerate for up to 1 day, turning occasionally. Cover and refrigerate the reserved marinade.

  2. Prepare an outdoor grill for medium-high cooking over direct heat.

  3. Remove the steak from the marinade (discard the marinade) and grill, turning halfway through cooking, for a total of about 10 minutes, until the meat feels only slightly resilient when pressed with a fingertip for medium-rare. Transfer the steak to a cutting board and let stand for 5 to 10 minutes.

  4. Meanwhile, prepare the tacos: In a large bowl, toss the cabbage, carrots, spring onions, and coriander together.

  5. Heat the tortillas on the grill, turning occasionally, for about 1 minute, or until hot. Transfer to a serving bowl and cover to keep warm.

  6. To serve: Cut the steak across the grain into 1/4-inch-thick slices. Transfer the steak slices and any carving juices to a platter. Serve the steak with the reserved marinade, tortillas, cabbage mixture, and guacamole. Let each guest fill two tortillas with some steak and cabbage mixture and top with some of the marinade and guacamole.
