Healthy and Delicious Sheet Pan Chicken Fajitas


  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon kosher salt
  • 1/2 teaspoon ground black pepper
  • 2 tablespoons vegetable oil
  • 1 1/2 pounds boneless, skinless chicken breasts, thinly sliced
  • 1 large onion, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 1 yellow bell pepper, thinly sliced


  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius) and line a large baking sheet with parchment paper or aluminum foil.
  2. In a small bowl, combine the chili powder, ground cumin, smoked paprika, onion powder, garlic powder, kosher salt, and ground black pepper.
  3. In a large bowl, mix together the sliced chicken, onion, and bell peppers. Drizzle the vegetable oil over the mixture and toss until the ingredients are evenly coated.
  4. Sprinkle the prepared seasoning mix over the chicken and vegetables, stirring to ensure even coverage.
  5. Spread the seasoned chicken and vegetables in a single layer on the lined baking sheet.
  6. Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender.
  7. Optional: For added char and flavor, broil the fajitas for an additional 2-3 minutes, watching closely to avoid burning.
  8. Remove the sheet pan from the oven and let the fajitas rest for a few minutes before serving with your favorite fajita accompaniments, such as tortillas, sour cream, salsa, guacamole, and shredded cheese.
