Sheet Pan Chicken Fajitas

I recently discovered this quick and easy method for preparing chicken fajitas.  The seasoned chicken and veggies are roasted in one pan in the oven.  While they are cooking, there is time to prepare the guacamole and other fixin's.

  • 4 chicken breasts (about 1 pound), thinly sliced
  • 1 red pepper, sliced
  • 1 green pepper, sliced
  • 1 yellow pepper, sliced
  • 1 medium onion,  halved and then cut in slices
  • 1-2 Tablespoons olive or vegetable oil
  • fajita seasoning (recipe below) or 2 tablespoons of packaged taco seasoning mix
  • 6 - 8" tortillas 
  • Avocado, salsa, sour cream, cheese for toppings.

 Fajita Seasoning:
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1/4 teaspoon garlic powder  
  • dash of red pepper flakes
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper  

  1. Preheat oven to 425°F.
  2. Line a baking sheet with parchment paper for easy clean-up.
  3. Combine seasoning ingredients in a small bowl.
  4. Distribute the veggies and chicken pieces evenly over the bottom of the pan.  Drizzle with oil and sprinkle with seasonings. Toss to coat.
  5. Bake for 15 minutes.  
  6. Stir and return to oven for another 10 minutes or until chicken is fully cooked and veggies are tender.
  7. Serve hot from the oven on warm tortillas with optional toppings, as desired.


  1. This is a brilliant idea Judy. Fast, easy and almost no cleanup!

  2. That looks amazing! I am making a note of the seasoning - so great to make your own. This would be great for a camping meal too! Yum.

  3. I already know we would love this! We eat fajitas regularly and will try it this way.

  4. Made these for supper last night, quick easy and delicious! A bit spicy so will adjust that next time.

    1. Thanks so much for taking the time to leave a comment/review after trying the recipe.

  5. I also made this yesterday for supper. I didn't use very much of the seasoning as we don't care for it to be too spicy. Next time I will use more and there definitely will be a next time. I will also slice the peppers and onions a bit larger as they were well cooked in only 15 min. The chicken was done by then as well. Certainly an easy way to make fajitas with no mess on the stove top!
