  • 1 ½ pounds boneless skinless chicken breasts sliced into thick strips
  • 3 bell peppers cored and sliced into strips
  • 1 red onion thinly sliced
  • 2 cloves garlic clove minced
  • 3 tablespoons olive oil


For serving

  • Flour tortillas
  • Lime wedges
  • Fresh cilantro
  • Avocado


  • Preheat oven to 425°F. Grease a large rimmed baking sheet with cooking spray.
  • Place the chicken, peppers, onions, garlic and olive oil on the baking sheet.
  • Combine the ingredients for the seasoning in a small bowl, then sprinkle evenly over the chicken and vegetable mixture on the baking sheet.
  • Toss everything together with tongs or your hands to evenly coat. Spread into an even layer, ensuring that the chicken strips are on top of the vegetables and overlapping each other
  • Cook in the preheated oven, tossing once halfway through cooking, until the chicken is cooked through and the vegetables are tender, about 15 - 20 minutes.
  • Place tortillas in foil and wrap tightly; and warm in oven during last 5 minutes of the fajitas cooking.
  • Serve the fajitas with the warmed tortillas, along with lime juice, cilantro, and sliced avocados, if desired.


Storage: I recommend enjoying the chicken fajitas as soon as you make them since chicken can dry out easily. However, if you do have leftovers, you can wrap them in aluminum foil to keep warm for a couple hours at room temperature. Or store them in the fridge in an airtight container for a couple days. To reheat, place them on a pan or in in the microwave until heated through.
Substitutes: Feel free to substitute different kinds of spices, peppers and onions. It's a very flexible and forgiving recipe.
