Flavorful Chicken Fajitas

I love seasoning my chicken fajitas with my Homemade Taco Seasoning. The seasoning is super easy to make and you can use it on so many things. I recommend that you make a batch even though you’ll only use a small amount for this recipe.

If you don’t want to make a whole batch, I have also included in the recipe instructions, the exact amount of spices needed for this recipe alone. Either way, you will have some super flavorful fajitas your whole family will enjoy.

Topping Suggestions for Chicken Fajitas

We absolutely love loading up our fajitas with all kinds of goodies. I, of course, love adding lots of slices of the peppers and onions that cooked with the fajitas. We use flour tortillas at home, but you can certainly make them with corn tortillas.

Our favorite toppings include pico de gallo, sour cream, (though we prefer mantequilla like this one), queso fresco or shredded Mexican blend cheese, avocado slices or fresh homemade guacamole. There are so many yummy options for toppings!

How to Make Sheet Pan Chicken Fajitas

Making sheet pan fajitas couldn’t be easier. The part that will require the most effort is slicing the chicken breasts, peppers, and onions. If you want to save some time, you can buy the pre-sliced onions and peppers most supermarkets sell. Once everything is sliced, the rest is a breeze!

You’ll coat the chicken strips with the spices, oil and the juice of one lemon. Letting the chicken sit to marinate for a bit will give you the best results. In the meantime, you will spread the veggies on a sheet pan and sprinkle them with spices and oil also. You can toss them to make sure they get coated evenly.

You will then lay the chicken strips on top of the veggies. You then roast the fajitas for 10 minutes, at which point you’ll take them out and toss them around. You can now put them back in and cook them for approximately 5 to 10 more minutes. Make sure to use a meat thermometer to test the chicken for doneness.

for the Seasoning

for the Fajita Filling

  • 1 ½ lbs boneless skinless chicken breasts sliced into 1/2-inch thick strips
  • 3 bell pepper(s) multi-colored, rinsed, cored and sliced into strips
  • 1 large yellow onion halved and thinly sliced
  • 2 tbsps extra virgin olive oil
  • 1 lime juiced

optional Toppings


  • Preheat oven to 425° F.

prepare the Seasoning

  • Combine the chili powder, cumin, salt, pepper, paprika, garlic powder, onion powder, dried oregano, and cayenne pepper in a small bowl. Alternatively, you can use 3 tablespoons of my Homemade Taco Seasoning.

prepare the Sheet Pan

  • Lightly spray a rimmed baking sheet with non-stick cooking spray.

prepare the Vegetables

  • Slice the bell peppers and onions. Spread the sliced bell peppers and onions evenly across the baking sheet and drizzle with 1 tablespoon of the oil and season with 1 tablespoon of the seasoning. Toss the peppers and onions until evenly coated in the oil and seasoning and then spread out into an even layer.

prepare the Chicken

  • Slice the chicken into 1/2-inch thick strips and place in a small bowl with the remaining seasoning, lime juice, and 1 tablespoon of olive oil. Toss until the chicken is fully and evenly coated. While optional, if time permits, it's best to allow the chicken to marinate for 20 to 30 minutes.
  • Place the chicken strips over the bed of peppers and onions.


  • Place the baking sheet on the middle rack of the oven and roast. Toss the chicken and veggies after 10 minutes of cooking and return to the oven for another 5 to 10 minutes until the vegetables are tender and the chicken is cooked through. Use a kitchen thermometer to make sure the chicken has reached an internal temperature of 165°.
  • Serve and enjoy!

  • Megan says:

    If I have frozen peppers and onions could I use that on the sheet pan for this recipe?

    • Hi Megan! I have not tried it with frozen veggies but I think you’ll be fine using them. They should cook through with no problem, you may have a bit more water release from them. Let me know how it goes!

  • Dawn Conklin says:

    Fajitas are always good! It’s funny too because the kids were just asking about when we are having them again. I haven’t tried them on a sheet before, but definitely going to try them this way! Nice and simple 🙂
