Sheet Pan Chicken Fajitas is an easy, 30 minute dinner all baked on a sheet pan! Chicken, bell peppers, and onion with a delicious fajita seasoning. Serve them on tortillas with your favorite toppings!

I love a sheet pan dinner. Throw everything on one pan, put in the oven, and go about my business? I love that.
I also love chicken fajitas and this is officially my favorite way to make them at home. The chicken, bell peppers, and onion are cook on the same pan in about 20 minutes. But before that, they're coated in a delicious (and easy!) homemade fajita seasoning.
It's so flavorful, so easy, and so satisfying. Serve it on tortillas with all your favorite fajita toppings or, like my kids did, roll it up in burrito-size tortillas with rice and beans.

Ingredients
- Chili powder, salt, paprika, onion powder, garlic powder, cumin, cayenne, and black pepper - this is all going to combine to make a homemade fajita seasoning. You could also buy a premade fajita seasoning mix.
- Chicken - I suggest boneless, skinless chicken breasts for this recipe because thighs would be too fatty.
- Bell peppers - you can use any color of bell pepper. I like how the red and yellow look in fajitas.
- Red onion - you could use a different color but, again, I like how the red onion looks.
- Olive oil - this is going to help the fajita seasoning stick to the chicken and vegetables and keeps everything from drying out in the oven.
- Tortillas - you can use flour or corn tortillas.
- Toppings - there are so many options for fajita toppings! Sour cream, cheese, guacamole, salsa, lime juice, cilantro - use whatever you prefer on your fajitas.

How To Make Sheet Pan Fajitas
- Fajita seasoning. Combine chili powder, salt, paprika, onion powder, garlic, powder, cayenne, and black pepper. Set aside.
- Prep. Slice chicken into ½-inch pieces and put in a mixing bowl. Slice peppers and onion; add to mixing bowl.
- Combine. Add oil and fajita seasoning to the mixing bowl and toss until chicken and vegetables are coated.
- Transfer. Spread in a single layer on a rimmed baking sheet lined with parchment paper.
- Cook. Bake at 400F for 20 - 25 minutes until chicken is cooked through and vegetables are nicely roasted.
- Serve. Serve on tortillas with preferred toppings.

How Long Is It Good For?
Chicken fajitas are good for up the 3 days in the refrigerator. Make sure to store them in an airtight container.
You can reheat it in the microwave.
Can You Freeze It?
You can freeze the chicken and vegetables for up to 3 months. I wouldn't try to freeze assembled fajitas. Let the chicken and vegetables cool completely and then put them in an airtight container, like a freezer ziploc bag. Place in the freezer.
When you are ready to serve, let it defrost overnight in the fridge and reheat in the microwave.
