Prep the Chicken and Veggies

To make sheet pan chicken fajitas, start by slicing chicken breast into long strips. You can also use chicken thighs. Thinly slice an onion (yellow or red onion works) and three bell peppers. I used green, red and yellow bell peppers to make the dish more colorful, but you can use any color pepper you’d like.

Season It

Next, make the fajita seasoning using basic Mexican spices that you will likely already have in your pantry. In a small bowl, mix together chili powder, ground cumin, ground coriander, smoked paprika, garlic powder, dried oregano, ground black pepper, and salt.

Add a couple of tablespoons of oil to the seasoning blend to create a mixture that you can coat the chicken and veggies with. I like to use avocado oil because it has a high smoke point and therefore can be cooked at high temperatures.

Bake the Chicken Fajitas

To make cleanup a breeze, line the baking sheet with foil. If you don’t have any, spray the baking sheet with some cooking spray to prevent sticking.

Once the chicken and veggies have been coated with the seasoning, spread everything out evenly on the baking sheet so it cooks evenly.

Squeeze some fresh lime juice over the finished product for some extra flavor.

How to Serve Sheet Pan Chicken Fajitas

Serve the fajita filling in soft taco shells and add your favorite fajita fixings: guacamole, salsa, pico de gallo, chopped cilantro, or shredded cheese if you eat dairy.

You can also make a fajita bowl by serving the filling and any toppings over rice.

Finally, if you want a low carb, paleo, or Whole30 meal, eat the fajita filling without the taco shell or rice. Just add some diced avocado or pico de gallo.
