Ingredients
  

  • 1 ½ pounds flank steak or skirt steak
  • 3 tablespoons olive oil divided
  • 3 bell peppers various colors, thinly sliced
  • 1 large onion thinly sliced
  • 2 teaspoons chili powder
  • 1 teaspoon paprika
  • 1 teaspoon cumin
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon crushed red pepper flakes optional for spice
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • Juice of 1 lime
  • Fresh cilantro for garnish
  • Warm flour or corn tortillas for serving
  • Optional toppings: sour cream guacamole, salsa, shredded cheese

Instructions
 

  • In a small bowl, combine the chili powder, paprika, cumin, garlic powder, onion powder, red pepper flakes (if using), salt, and black pepper.
  • Rub the steak with 1 tablespoon olive oil and season all over with the spice mixture. Let it marinate for at least 30 minutes, or up to 2 hours for deeper flavor.
  • Heat 1 tablespoon olive oil in a large skillet or cast iron pan over medium-high heat.
  • Add the steak and cook for about 4–5 minutes per side for medium-rare, or until desired doneness. Remove from the pan and let it rest for 5 minutes before slicing thinly against the grain.
  • In the same pan, add the remaining tablespoon of olive oil. Toss in the bell peppers and onions. Sauté for 5–7 minutes until softened and slightly charred.
  • Return the sliced steak to the pan and toss everything together. Squeeze fresh lime juice over the top and stir.
  • Serve immediately with warm tortillas and your favorite toppings!

Notes

  • Flank steak and skirt steak are ideal for fajitas because they cook quickly and stay tender when sliced against the grain.
  • Marinating the steak longer improves flavor, but it isn’t strictly necessary if you’re short on time.
  • Want extra flavor? Add a splash of orange juice to the marinade for a slight citrusy touch.
  • Use a cast iron skillet for the best sear and smoky char on both the steak and veggies.
