Ingredients

Scale
  • 1 to 1.5 pounds flank steak (450-680g), lean and well-marbled
  • 4 cloves garlic, minced
  • Juice and zest of 2 fresh limes
  • 3 tablespoons extra virgin olive oil
  • 1 teaspoon ground cumin
  • 1 teaspoon chili powder
  • Salt and pepper to taste
  • 3 medium bell peppers (red, yellow, green), sliced into thin strips
  • 1 medium yellow onion, thinly sliced
  • Handful of fresh cilantro, chopped (optional)
  • Flour or corn tortillas, warmed for serving

Instructions

  1. In a medium bowl, whisk together minced garlic, lime juice and zest, olive oil, ground cumin, chili powder, salt, and pepper to make the marinade.
  2. Pat the flank steak dry with paper towels. Place steak in a shallow dish or zip-top bag and pour marinade over it, turning to coat fully. Marinate for at least 20 minutes at room temperature or up to 2 hours in the fridge.
  3. While steak marinates, slice bell peppers into thin strips and onion into thin half-moons. Toss with 1 tablespoon olive oil, salt, and pepper. Set aside.
  4. Heat grill or grill pan over medium-high heat until very hot.
  5. Remove steak from marinade, letting excess drip off. Grill steak for 4-5 minutes per side for medium-rare (130°F/54°C internal temperature) or longer for desired doneness. Transfer to cutting board and rest for 5-10 minutes.
  6. While steak rests, heat a skillet over medium heat. Add pepper and onion mixture and sauté, stirring often, until softened and slightly caramelized, about 8-10 minutes.
  7. Warm tortillas briefly on grill or in dry skillet until pliable with slight char marks. Wrap in a kitchen towel to keep warm.
  8. Slice steak thinly against the grain. Assemble fajitas by layering sliced steak and sautéed peppers onto warm tortillas. Garnish with fresh cilantro if desired and add extras like avocado, sour cream, or salsa.

Notes

Pat steak dry before marinating to ensure better searing. Let steak come to room temperature before grilling to avoid uneven cooking. Slice steak thinly against the grain after resting to keep it tender. Medium heat is key for sautéing peppers to get caramelization without burning. Multitask by prepping veggies while steak marinates to save time.
