Sheet Pan Fajitas is a quick and easy meal with chicken, bell peppers, and onions. Super fast to make and requires very little hands on time. Bonus, this recipe is in my fall cookbook! 


  • 2 teaspoons chili powder
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon cumin
  • 1 teaspoon salt
  • ½ teaspoon ground black pepper
  • 1 ½ pounds boneless skinless chicken, cut into ½-inch slices
  • 1 tablespoon olive oil
  • 3 large bell peppers, cut into strips (any colors you prefer)
  • 1 medium white onion, cut into thin strips
  • Juice of 1 lime
  • 2 tablespoons chopped cilantro, optional
  • 12 small corn or flour tortillas for serving
  • Lime wedges, sour cream, grated cheese, guacamole, optional for serving


  1. Preheat the oven to 400 degrees F., and spray a large rimmed baking sheet with cooking spray (the baking sheet should be roughly 17x12 inches).
  2. In a small bowl, add the chili powder, garlic powder, smoked paprika, cumin, salt, and pepper. Stir well to combine and set aside.
  3. Add the chicken to the sheet pan and drizzle with the olive oil. 
  4. Sprinkle the seasoning mixture over the chicken, and toss well to combine. 
  5. Add the bell peppers and onion to the sheet pan, and toss gently to combine.
  6. Bake until the chicken is cooked through, about 20 minutes. Check a few of the largest pieces to make sure they register 165 degrees F. on an instant-read thermometer. 
  7. When the chicken is cooked, remove from the oven.
  8. Toss lightly to combine again. 
  9. Drizzle the pan with the juice of 1 lime and sprinkle with chopped cilantro if using. 
  10. Serve in warmed tortillas with additional toppings of your choice.


  1. This recipe is really easy to scale up and cook for a crowd! It’s a favorite at our house to serve friends and family. 
  2. You can add additional peppers and onions to your liking. I normally add another pepper or two because I like them the most and hope to have leftovers. 
  3. Sometimes I’ll serve the fajita toppings over chopped lettuce with additional toppings like cheese and salsa to make an easy fajita salad.
