Can I Use Different Fajita Vegetables?
Of course! Onion and bell peppers are the most traditional veggies included in fajitas, but you can include anything you have on hand. Just keep in mind that you may have to adjust the cook time slightly if you want to include heartier veggies.

Should I Line the Sheet Pan?
Nope! The chicken and veggies slide right off the sheet pan, so there’s no need to line it with foil or parchment paper.

How to Reheat Chicken Fajitas
If you have leftover sheet pan fajitas, I recommend heating the leftovers in a skillet on the stove. This will prevent the chicken from becoming rubbery and the peppers from turning to mush in the microwave.

Tips for the Best Chicken Fajitas
You’ll know when the chicken is finished cooking when it’s 165 degrees F in the center.
Make sure to toss the fajitas halfway through the baking time to ensure everything cooks evenly.
Toppings are optional, but my family loves these easy fajitas with sour cream, avocado, shredded cheese and tomatoes.

2 tsp chili powder (preferrably 1 tsp ancho chili powder 1 tsp regular)
1 1/2 tsp ground cumin
1 tsp ground paprika
1/2 tsp ground coriander
Salt and freshly ground black pepper
Fajita filling
1 1/2 lbs boneless skinless chicken breasts , sliced into 1/2-inch thick strips (slice extra wide strips in half)
2 of each red , green and yellow bell peppers, cored and sliced into strips (3 whole total)
1 medium yellow onion , halved and sliced from top to root
2 cloves garlic , minced
3 Tbsp olive oil
2 Tbsp fresh lime juice
3 Tbsp chopped cilantro
For serving
8 taco size flour tortillas
Sour cream , avocado slices or guacamole, diced tomatoes, Mexican cheese blend (toppings are optional)
Preheat oven to 400°F (200°C). Spray an 18 by 13-inch rimmed baking sheet with non-stick cooking spray.
For the seasoning: In a small mixing bowl whisk together chili powders, cumin, paprika, coriander, 1 1/2 tsp salt and 1/2 tsp pepper, set aside.
For the fajitas filling: Spread bell peppers and yellow onion onto baking sheet.
Top with chicken strips then sprinkle garlic and seasoning evenly over chicken strips.
Drizzle olive oil over top then toss everything to evenly coat. Spread into an even layer working to keep chicken from overlapping.
Roast in preheated oven, tossing once halfway through cooking, until veggies are tender and chicken has cooked through, about 18 – 25 minutes (test a few of the larger pieces to make sure they are 165 in the center).
Wrap tortillas tightly in foil and warm in oven during last 5 minutes of fajita filling cooking.
Drizzle lime juice evenly over top of the chicken fajita filling, sprinkle with cilantro and more salt to taste and toss to coat.
Serve filling warm in warm tortillas with desired toppings.
You don’t need to line your sheet pan with foil or parchment paper, non-stick spray does the job!
