Sheet pan chicken fajitas are an easy one pan meal that’s made with juicy chicken thighs, peppers, onions, and fajita seasoning.
What are sheet pan chicken fajitas?
Sheet pan chicken fajitas are just like classic chicken fajitas, but instead of making them on the stovetop, they’re made on a sheet pan in your oven.
Sheet pan chicken fajitas are typically made with chicken breast or thighs, peppers and onions, and fajita seasoning. The chicken strips, peppers, and onions are tossed in oil and fajita spices and then baked in the oven until fully cooked and ready to assemble.

What is Needed to Make Shee Pan Chicken Fajitas
One thing we love about this sheet pan chicken recipe is that you really only need a handful of whole ingredients to get started.
Chicken: we’re using boneless, skinless chicken thighs. But, we’ve also tried this recipe with breasts, too.
Peppers: feel free to use any color of bell pepper you wish. We used 4 different ones to add nice pops of color to the meal.
Onions: you can use a white, yellow, or red onion.
Oil: we used avocado oil, but olive oil works too.
Salsa: salsa is used to give the chicken a bit of extra flavor. Check out our homemade salsa recipe.
Fajita Seasoning: what would fajitas be without the seasoning? Feel free to use store-bought or make your own.
3 Ways to Serve Sheet Pan Chicken Fajitas
While the most common way to serve this chicken fajita recipe is in a street taco tortilla with fajita fixings, you can also serve it a few other ways, too!
Classic Fajitas
Serve this sheet pan recipe just like classic fajitas. Serve in a mini tortilla (flour or corn) and top with:
- sour cream
- shredded cheese or queso
- cilantro
- guacamole
Fajita Burrito (or bowl)
Burrito fan?! Use an XL tortilla to serve these as a burrito just like Chipotle. Layer in:
- Black or pinto beans
- Cilantro lime rice
- Salsa
- Sour cream
Nachos
If you love chips like us, these fixings are the perfect thing to make nachos out of. Layer a sheet pan with tortilla chips and top with the chicken fajitas + shredded cheese any any other toppings.
Top Tips
Make your own fajita seasoning: whenever possible, we like to make our own spice blends. Fajita seasoning is one of our most popular recipes on FFF.
Make it!
Fajita Seasoning
Make your own all-purpose fajita seasoning at home with just 6 basic spices! You can use our homemade fajita seasoning recipe on chicken, steak, veggies, soup, and more.
Use chicken thighs vs. breast: we know that it’s tempting to use chicken breast for this recipe, but we really recommend chicken things. They’re so much juicier and hold flavor better.
Slice evenly: make sure that you slice your chicken strips evenly so that they cool evenly. Same with the peppers and onions.

- If you’d like the fajitas to be spicier, add ½ -1 teaspoon of red pepper flakes.
