Chicken Breasts – Boneless skinless chicken breasts, sliced into thin strips about 1/2″ to 3/4″ wide and 2-3 inches long.
Bell Peppers – any color you’d like, cut into 3/4″ wide strips.
Red Onion
Fajita Seasoning– you can use homemade or storebought. The homemade version I use is listed on the recipe card at the bottom of the post.
Olive Oil – this keeps the veggies from sticking and helps the fajita seasoning to coat the chicken and veggies.

How to Make Single Sheet Pan Fajitas

Prep the chicken breast:

For the chicken breast, slice the meat into long strips 1/2″ to 3/4″ inch wide.

Depending on how thick the breast is, you may need to turn the strip on its side and cut that in half so that your strips are 1/2″ wide on all sides. Trim the chicken so that each strip is 2-3″ long.

The peppers and onions should be sliced into 1/2″ to 3/4″ wide strips.

Spices for fajita seasoning in a white dish.

Step 1: If you’re making your own, combine all the spices for the fajita seasoning in a small bowl and set aside.

Preheat the oven to 425°F, move oven rack to middle position and spray a large sheet pan with cooking spray.

Step 6: Bake for 15-20 minutes until the thickest piece of chicken is no longer pink in the middle and registers 165F on a meat thermometer.

Toss and turn the chicken and veggies so that they are getting an even coating of spices and juices.

Step 7: Remove the pan from the oven and shift the oven rack to the top third level of the oven.

Set the broiler to high and broil chicken and vegetables until the chicken starts to get a little crisp on the edges and the veggies start to get a little char on them, 3-5 minutes.

Step 8: Remove from the oven and serve with sour cream and your favorite toppings like pico de gallo and guacamole.

Top Tip: Make sure the chicken pieces are sliced into thin strips and the veggies look a little wider than the chicken pieces. This will ensure that everything is cooked evenly and done at the same time.

Substitution and Variations

For the Chicken – You can also use shrimp or thinly sliced steak or pork in this recipe. For a vegetarian option try sweet potato, jackfruit, extra firm tofu, or vegan chicken strips.

For the Peppers and Red Onions – I like to switch things up sometimes and I’ll use veggies like squash and zucchini, sweet corn, or even pineapple. Pineapple goes great with pork or shrimp fajitas.

For the Fajita Seasoning – These fajitas can also be made with a package of store-bought taco seasoning, or try my all purpose Mexican seasoning as a simple sub for homemade fajita seasoning.

How to Prepare Fajitas Ahead of Time

Another reason to love this easy chicken fajita recipe is that it can be made ahead!

Prepare the recipe up until the baking step and then put it in the fridge. When you’re ready for dinner, cook the fajitas per the recipe instructions.

-OR-

Prepare the chicken and vegetables. Bake until the chicken is cooked through. Remove from the oven and let cool. Store in the fridge. About 30 minutes before dinner, remove the tray from the fridge to get the chill out. Set the broiler to high and broil the fajitas until the chicken has some crispy edges and there is a little char on the veggies.

Helpful Tips & Tricks for the Best Results

I recommend using skinless chicken breast. You can find it everywhere, and it cooks beautifully with the veggies.
Cut the chicken strips thinner than the vegetables. This will ensure everything will be done at the same time and cooked thoroughly.
Make sure the chicken and the veggies are evenly coated in the chicken fajitas seasoning mixture.
Do your best not to overstuff the tortilla. Good luck.

Cleanup hack: Line the sheet pan well with foil for even easier cleanup.
