Zesty Lime & Cilantro Flank Steak Tacos

These Zesty Lime Flank Steak Tacos feature lean, citrus-marinated beef served in whole-grain corn tortillas. They are topped with a crisp cabbage and radish slaw for crunch and fresh avocado for healthy fats, providing a high-protein, fiber-rich alternative to traditional street tacos.

  • Prep time: 15 mins (+ 30 mins marinating)
  • Cook time: 10 mins
  • Servings: 4 (3 tacos each)

Ingredients:

  • The Steak & Marinade:
    • 1 lb Flank Steak
    • 2 tbsp Olive oil
    • Juice of 2 Limes
    • 2 cloves Garlic (minced)
    • 1 tsp Cumin
    • 1/2 tsp Chili powder
  • The “Crunch” Slaw:
    • 2 cups Shredded cabbage (purple or green)
    • 4 Radishes (thinly sliced)
    • 1/4 cup Fresh cilantro (chopped)
    • 1 tbsp Apple cider vinegar
  • The Assembly:
    • 12 Small corn tortillas (corn is whole grain and lower calorie than flour)
    • 1 Avocado (sliced)
    • Optional: Pickled jalapeños

Instructions

  1. Marinate: In a bowl or zip-top bag, combine the olive oil, lime juice, garlic, cumin, and chili powder. Add the flank steak and coat well. Let it sit in the fridge for at least 30 minutes (up to 4 hours).
  2. Make the Slaw: While the steak marinades, toss the cabbage, radishes, cilantro, and vinegar in a bowl. Season with a pinch of salt. Let it sit so the flavors meld.
  3. Grill/Sear: Heat a cast-iron skillet or grill to high heat. Remove steak from marinade and pat slightly dry. Sear for 4–5 minutes per side for medium-rare.
  4. The Secret Step: Transfer the steak to a cutting board and let it rest for 10 minutes. This keeps the juices inside so the meat stays tender.
  5. Slice: Slice the steak very thinly against the grain. This is crucial for flank steak to ensure it isn’t chewy.
  6. Char & Serve: Quickly warm your tortillas over a gas flame or in a dry pan until pliable. Fill with steak, top with the crunchy slaw and a slice of avocado.
