Whenever I go to my local Mexican restaurant, I order the chicken fajitas. I just can’t resist that tender chicken and veggies with all the fun toppings! My homemade version tastes totally authentic, and is great for feeding a crowd.

How do you make chicken fajitas?

This recipe starts with chicken breasts, which are sliced then soaked in a flavorful marinade. The marinade is a combination of lime juice, olive oil and plenty of spices. An assortment of peppers and onions are also coated in the same marinade. Place your marinated chicken and vegetables in a hot pan, then cook until chicken is done and vegetables are tender. Add a sprinkle of cilantro, then serve and enjoy.

Tips for the best fajitas

  • I like to use sliced chicken in this recipe, but you can also marinate whole chicken breasts. Cook the whole chicken breasts, then slice them and layer over the cooked peppers.
  • I like to use an assortment of bell peppers, it makes for a more festive presentation. You can use all of one color pepper if you prefer, or even try other varieties of pepper such as fresh Anaheim chiles.
  • You can saute, broil or grill your fajitas. The various cooking times and methods are outlined in the recipe below.

What do you serve with chicken fajitas?

When I make this dish I serve it with tortillas, pinto beans and rice, and a variety of toppings. You can use flour or corn tortillas, whichever you prefer. Watching your carbs? Skip the rice and tortillas and serve your chicken and vegetables over cauliflower rice. Some of my favorite toppings include shredded cheese, sour cream, guacamole, salsa, lettuce and olives. I typically put out bowls of all the different toppings and let everyone serve themselves to make their own creations.

Chicken fajita variations

  • Protein: Try using chicken thighs instead of chicken breasts, or use a different type of protein such as flank steak, pork tenderloin, shrimp or fish.
  • Vegetables: Add more veggies to the mix such as mushrooms, zucchini, poblano peppers, tomatoes or corn.
  • Flavorings: You can add more flavors to the marinade such as hot sauce, dried oregano, minced canned chipotle peppers or fresh cilantro.

    These were absolutely delicious but I have never met chicken in my life that only take 6 minutes or even eight minutes to cook thoroughly unless it’s sliced extremely thin. Dumped everything in my cast iron skillet and cooked for 25 minutes stirring frequently. They came out perfect so flavorful!

    These fajitas are better than any restaurant fajitas. They are packed with flavor. I drained the mixture well before cooking in a preheated cast-iron skillet. Also used poblano peppers which I had on hand instead of bell peppers. This will be our go to fajita recipe. Thank you
