Equipment

  • knife
  • cutting board
  • Oven
  • Measuring spoons
  • Measuring cups

Method
 

  1. Preheat your oven to 450°F (232°C).
  2. Slice the bell peppers, red onion, and jalapeño (if using) into thin strips.
  3. In a large bowl, toss the chicken strips with 1 tablespoon of olive oil, fajita seasoning, chili powder, cumin, smoked paprika, salt, and pepper. Ensure the chicken is evenly coated.
  4. In the same bowl, toss the sliced bell peppers, red onion, and jalapeño (if using) with the remaining 1 tablespoon of olive oil, salt, and pepper.
  5. Spread the chicken and vegetables in a single layer on a large baking sheet. Avoid overcrowding the pan; use two baking sheets if necessary.
  6. Bake for 15-20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred.
  7. Serve immediately with warm tortillas and your favorite toppings.

Notes

For a smokier flavor, add a dash of liquid smoke to the chicken and vegetables before baking. You can also marinate the chicken in lime juice and garlic for a brighter, more citrusy flavor. Consider adding pineapple chunks for a sweet and tangy twist. To prevent sogginess, ensure the oven is fully preheated and avoid overcrowding the pan.
