What Are Chicken Fajitas?
Fajitas are a Mexican dish that is very similar to tacos. They are made with strips of meat, traditionally, grilled skirt steak, and mixed with chopped vegetables. Everything is then wrapped in a soft tortilla and topped with traditional toppings like guacamole, sour cream and pico de gallo.
Though fajitas are traditionally made with skirt steak, you can change up the flavor by using chicken, shrimp or any other protein you prefer. These easy Chicken Fajitas are packed with amazing Tex Mex flavor. They remind me a lot of the fajitas that we get at our favorite Mexican restaurant.
How to Make Easy Chicken Fajitas – Step by Step
- STEP 1: Cut chicken into strips: Slice the chicken into strips about 1/2 inch thick. For this recipe, I used boneless, skinless chicken thighs. You could easily use boneless, skinless chicken breast also. (Photo 1 below)
- STEP 2: Slice peppers: Using a separate cutting board and knife to avoid cross contamination with the chicken, remove seeds and slice bell peppers into strips. I like to use a variety of peppers in different colors but you can use any color you wish. (Photos 2-4 below)
- STEP 3: Arrange peppers on baking sheet: Arrange cut peppers down the sides of a rimmed baking sheet

- STEP 4: Add the chicken and season: Arrange the chicken in a single layer down the center of the baking sheet. Season chicken with Taco Seasoning Blend. (Photo 6 below)
- STEP 5: Slice onions: Slice onions into half moons. (Photo 7 below)
- STEP 6: Add onions and tomatoes to baking sheet: Arrange the sliced onions on top of the chicken and peppers and top with the diced tomatoes and green chilis (Photo 8 below)
- STEP 7: Bake: Place baking sheet in a preheated oven and bake for 25 minutes or until chicken is cooked through.
How to Finish Chicken Fajitas
You know the chicken is cooked through when the juices run clear or it has an internal temperature of 165 degrees F. I always use a meat thermometer 
When you remove the sheet pan from the oven, squeeze some fresh lime juice over the entire pan and add some chopped cilantro to add a fresh taste and wake up the flavors.
How to Serve Chicken Fajitas
Chicken Fajitas are the perfect grab and go meal. Just like tacos, you can pile these fajitas up with your favorite Tex Mex toppings. Here are some of my favorite toppings:
- Sour cream
- Guacamole
- Pico de Gallo
- Lime wedge
- Chopped cilantro
Wondering what to serve with Chicken Fajitas? I like to serve with Easy Mexican Rice and my Restaurant Style Black Beans. The beans are great because you can serve them on the side or pile them into the fajitas for an all-in-one meal.
Other Ways to Make Fajitas

Will you put back the baked fajita recipe? I make it weekly. You’d think I’d know it by heart after all this time but I always refer to the recipe. I’m distraught to see it replaced with the sheet pan fajita recipe.
Christina Hitchcock says
It’s pretty much the same recipe — just add a can of diced tomatoes to the pan. 🙂
melissa says
I was wondering if I need to cook the chicken partially or completly before adding the vegetables to it? Also can this be done in crock pot instead of oven? Thanks:)
Christina says
I bake everything together in the oven. I don’t partially cook the chicken first.
