Ingredients

Scale
  • 1½ pounds flank steak or skirt steak
  • 2 tablespoons olive oil (divided)
  • Juice of 1 lime
  • 2 bell peppers (red and green), sliced
  • 1 large onion, sliced
  • 1 teaspoon chili powder
  • 1 teaspoon paprika
  • ½ teaspoon ground cumin
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 8 small flour or corn tortillas
  • Optional toppings: fresh cilantro, sour cream, shredded cheese, guacamole, pico de gallo

Instructions

  1. In a small bowl, mix chili powder, paprika, cumin, garlic powder, onion powder, salt, and black pepper to create the fajita seasoning.
  2. Rub the steak with 1 tablespoon olive oil, lime juice, and half of the seasoning blend. Marinate for 30 minutes if desired.
  3. Preheat the Blackstone griddle to medium-high heat (about 400°F) for 10 minutes.
  4. Add remaining olive oil to the griddle and sauté sliced peppers and onions for 4–6 minutes until slightly charred but tender-crisp. Push to the side.
  5. Place the steak on the hot surface in a single layer. Cook undisturbed for 3–4 minutes per side until it reaches at least 145°F internal temperature.
  6. Remove steak from the griddle and let rest for 5–10 minutes.
  7. Slice the steak thinly against the grain.
  8. Return sliced steak to the griddle with vegetables and sprinkle remaining seasoning. Toss gently for 1–2 minutes to combine.
  9. Warm tortillas on the griddle for 20–30 seconds per side.
  10. Assemble fajitas with steak, vegetables, and desired toppings. Serve immediately.

Notes

  • Always slice steak against the grain for maximum tenderness.
  • Do not overcrowd the griddle to maintain proper searing.
  • Allow steak to rest before slicing to keep it juicy.
  • Adjust seasoning gradually to avoid excess salt.
  • Store steak and vegetables separately for best leftover texture.
