Ingredients
  

  • 3 boneless skinless chicken breasts approximately 1 pound
  • 1 medium onion
  • 1 lime
  • 3 bell peppers red, yellow, green or orange
  • 3 tablespoons olive oil divided
  • 1 teaspoon chili powder
  • ¾ teaspoon salt divided, more to taste
  • ½ teaspoon smoked paprika
  • ½ teaspoon onion powder
  • ½ teaspoon black pepper
  • ½ teaspoon cumin optional

Equipment

  • Large cast iron skillet
  • Medium bowl

Method
 

Phase 1: Prep & Marinate
  1. Begin by preparing your vegetables. Cut the onion into thin slivers and slice the bell peppers into uniform strips. Uniform slicing is crucial for even cooking, ensuring every piece gets that perfect tender-crisp texture.
  2. In a medium bowl, combine 1 tablespoon of olive oil, the juice of ½ lime, 1 teaspoon chili powder, ½ teaspoon smoked paprika, ½ teaspoon onion powder, ½ teaspoon black pepper, ½ teaspoon cumin (if using), and ½ teaspoon salt.
  3. Next, slice your boneless skinless chicken breasts into even chicken strips. Add the chicken to the spice mixture and toss thoroughly to ensure every piece is coated in this aromatic fajita marinade. Allow the chicken to marinate while you continue with the next steps, ideally for at least 20 minutes to absorb those delicious flavors.
Phase 2: High-Heat Searing
  1. Heat 1 tablespoon of olive oil in a large cast iron skillet (or other heavy-bottomed pan) over medium-high heat until it shimmers. This is where we build the flavor!
  2. Add half of the marinated chicken strips to the hot pan. Remember, do not overcrowd the pan; this is vital for achieving a beautiful sear and browning rather than steaming. Listen for that satisfying sizzle! Cook the chicken for about 3 to 5 minutes, or until it's just cooked through and beautifully golden brown with a slight char.
  3. Remove the cooked chicken from the pan and set it aside. Repeat with the remaining chicken, adding a little more oil if needed.
Phase 3: Sauté Vegetables & Combine
  1. With the chicken set aside, add the final 1 tablespoon of olive oil to the same hot pan. If you prefer a milder onion flavor, this is when you would drain any onions that have been soaking in cold water (a pro tip for reducing pungency!).
  2. Add the sliced onions to the pan and cook for about 2 minutes, until they just begin to soften and become fragrant.
  3. Now, add the sliced bell peppers to the pan. Season them with the remaining ¼ teaspoon of salt. Toss well to combine and cook for an additional 2 minutes, or just until the vegetables are hot and tender-crisp, with a slight char. Avoid overcooking, as we want them to retain a pleasant bite.
  4. Return all the cooked chicken to the pan with the sautéed vegetables. Stir everything together gently to combine, allowing the flavors to meld beautifully.
Phase 4: Finish & Serve
  1. Remove the pan from the heat. Squeeze additional fresh lime juice generously over the top of the hot Chicken Fajitas. If desired, sprinkle with fresh cilantro for an extra burst of freshness.
  2. Serve immediately with warm tortillas and your favorite toppings. Enjoy the sizzling sensation and incredible aroma!

Notes

Achieve incredible flavor by not overcrowding the pan; cook chicken and vegetables in batches for a beautiful sear. For milder onions, soak them in cold water before cooking. Always warm tortillas for a pliable experience, and finish with a squeeze of fresh lime and cilantro to brighten the dish.
