Ingredients

  • Fresh lime juice and cilantro: for finishing brighten and freshen the dish
  • Flour or corn tortillas: warmed for serving choose fresh or good quality packaged tortillas

Instructions

Slicing the Chicken and Vegetables:
Cut the chicken breast across the grain into even strips about one half inch thick so they cook evenly and stay tender. Slice the bell peppers and onion into similar sized strips for uniform roasting.
Preparing the Fajita Seasoning:
Combine chili powder cumin smoked paprika garlic powder onion powder salt and pepper in a small bowl to create a flavorful seasoning mix. Using fresh spices ensures the best aromatic punch.
Seasoning the Ingredients:
Place the vegetable strips on a sheet pan then layer the chicken strips on top. Sprinkle the seasoning evenly over the chicken and a little over the vegetables. Scatter the minced garlic over the chicken and drizzle olive oil across the entire pan to help everything roast beautifully.
Tossing and Spreading:
Gently toss the chicken and vegetable mixture on the pan to coat all pieces evenly with oil and seasoning. Spread everything out into an even single layer to ensure thorough roasting without steaming.
Baking the Fajitas:
Preheat the oven to 425 degrees Fahrenheit. Bake the sheet pan for 15 to 20 minutes until the chicken reaches an internal temperature of 165 degrees and the vegetables are tender with some charred edges.
Finishing and Serving:
Once out of the oven squeeze fresh lime juice over everything and sprinkle with chopped cilantro. Warm your tortillas and serve the fajitas with preferred toppings such as salsa sour cream guacamole and hot sauce.
