🔖Recipe Ingredient & Substitutions

Chicken — Both chicken breast and chicken thighs can be used. Boneless/skinless chicken is preferable. You can also make steak fajitas using the same marinade and the homemade fajita seasoning found in the ingredients list.
Veggies — Although you can use one type of bell pepper, I like using a mixture of colors which not only tastes great but makes for a prettier dish. I've left tomatoes as an optional ingredient, but I like to add one tomato for added flavor.
Lime Juice — When possible, use fresh lime juice over bottled.
Cayenne — For milder fajitas, reduce the amount of chili powder and don't use any cayenne pepper.
Tortillas — Serve with flour or corn tortillas.
Extras — You may also want to serve the fajitas with chopped cilantro, lettuce, avocado, and pico de Gallo.

🍗 How to Make This Mexican Fajita Recipe

Step 1: Slice chicken into thin strips and add to a large glass bowl. Next, slice peppers, onions, tomato, and garlic. Mix the sliced vegetables with the chicken.

Step 2: Juice enough fresh limes to equal ⅓ of a cup. Mix with the remaining marinade ingredients and whisk to combine. Pour the marinade over the chicken and massage the marinade into the chicken so that it's completely covered with the marinade.

Step 3: Marinate the chicken fajitas for a minimum of two hours.

Preheat oven to 400 degrees F

Step 4: Line a cookie sheet with foil then pour the chicken and vegetables into the tray, including the juices.

Step 5: Bake in a pre-heated oven for 25 minutes, then broil for up to five minutes. Keep an eye on the fajitas so that they don't burn.

🍽 Serving Suggestions

Serve with Easy Instant Pot Mexican Rice, warm tortillas, sour cream, guacamole, shredded cheese, and salsa.

🤷🏻‍♀️Recipe FAQs

Where Did Fajitas Originate?

You might think that fajitas originated in Mexico, but you'd be wrong! The credit actually goes to Mexican ranch hands in west Texas, who were called "vaqueros."

As part of their pay, the ranch hands were given the tough parts of the butchered cows, including the skirt steak. The vaqueros grilled the skirt steak, which they called "arracheras."

The word "fajita" was derived from the Spanish word “faja” which translates "strip" or “belt.” The strips of skirt steak were thought to resemble a leather belt, hence the name.

So technically, the word fajitas only refers to beef fajitas. However, over the years, it's become an all-encompassing name to describe beef, chicken, shrimp, and vegetable fajitas.

What do you serve with Chicken Fajitas?

Chicken Fajitas are usually served with corn or flour tortillas that are used to wrap the fajitas in. Guacamole, sour cream, and salsa are usually served on the side.

Mexican rice and black beans are sometimes served along with the fajitas.

👩🏼‍🍳Pro Tips

I juiced two limes to get ⅓ of a cup, however, it will depend on the size of the limes being juiced.
Lining the baking sheet with heavy foil makes cleaning a breeze!
If you prefer spice in your food, add some Serrano peppers in with the bell peppers before baking the chicken fajitas.
