  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon paprika
  • ½ teaspoon salt
  • ½ teaspoon black pepper
For the Fajitas:
  • 1 tablespoon olive oil
  • 1 red bell pepper sliced
  • 1 yellow bell pepper sliced
  • 1 green bell pepper sliced
  • 1 large onion sliced
For Serving:
  • 8 small flour or corn tortillas
  • Optional: sour cream guacamole, salsa, shredded cheese

Equipment

  • Cutting board
  • Sharp knife
  • Mixing bowl
  • Large skillet or cast-iron pan
  • Tongs or spatula

Method
 

Step 1. Marinate the Steak
  1. In a bowl, mix olive oil, lime juice, garlic, and spices. Coat the steak well and let it marinate for at least 30 minutes (or up to 8 hours for deeper flavor).
Step 2. Slice Vegetables
  1. Cut bell peppers and onion into thin, even strips to ensure even cooking.
Step 3. Cook the Steak
  1. Heat a skillet over high heat. Cook the steak for 3–5 minutes per side until nicely seared. Remove and let it rest for 5 minutes.
Step 4. Cook the Vegetables
  1. In the same pan, add olive oil and sauté peppers and onions over medium-high heat until slightly charred but still crisp.
Step 5. Slice the Steak
  1. Cut the rested steak into thin strips against the grain for maximum tenderness.
Step 6. Combine
  1. Return the sliced steak to the pan with vegetables and toss for 1–2 minutes to blend flavors.
Step 7. Warm Tortillas
  1. Heat tortillas in a dry skillet or microwave until soft and flexible.
Step 8. Assemble and Serve
  1. Fill tortillas with the steak and vegetable mixture. Add toppings as desired and serve immediately.

Notes

  • Always slice steak against the grain to keep it tender.
  • Do not overcrowd the pan; cook in batches if needed for proper searing.
  • Marinating longer enhances both flavor and tenderness.
  • Avoid overcooking vegetables to maintain slight crunch.
  • Cast iron pans work best for achieving a good sear.
