Ingredients for Chicken Fajitas

As always, this is a quick overview of the ingredients you need for this recipe. For the complete, printable recipe keep scrolling to the recipe card.

  • Chicken: boneless skinless chicken breast or boneless chicken thighs work best for this recipe.
  • Produce: Bell Peppers, Onions, Red Onions, Jalapenos, Garlic, Limes, and Cilantro
  • Tortillas: corn tortillas are traditionally used but flour or low-carb tortillas will also work.
  • Olive oil: oil is used in the marinade, you can also use avocado oil if you prefer.
  • Sweetener: this recipe requires a small amount of sweetener in the marinade. This can be regular brown sugar or a low-carb alternative such as monkfruit.

Rub or Marinade

There are two common ways to prepare fajitas. You can make a marinade and allow the ingredients to soak up all of that flavor, or make a rub and simply season the ingredients. Both are great options, but for this recipe, I prefer to use a citrus-based marinade.

These chicken fajitas are soaked in a jalapeno lime marinade that infuses the dish with tons of flavor! The marinade requires a few basic ingredients, but most of them you probably have on hand.

How to Make Chicken Fajitas

These fajitas come together in a few basic steps, marinate, grill, assemble. It truly is super easy. However, if you’ve never made fajitas and it seems daughting I’ve documented the entire process below.

Marinate the Chicken

Combine all of the ingredients in a large plastic bag. Once the marinade is combined remove 2 tablespoons and set aside, you will need it later. Cut the chicken into small strips, when considering the size be sure to cut the chicken into small enough pieces it will fit in the tortillas. Add the chicken strips to the marinade and toss to coat. Allow the chicken to marinade at least 1 hour, but up to 24. Remember, the longer it marinates the more flavorful the chicken will be

Slice Peppers and Onions

Thinly slice the peppers and onions. Drizzle with olive oil, salt and pepper and toss to coat.

Heat the Grill

Heat a grill to medium heat, about 350 degrees F. This can be an outdoor grill, or a grill pan if needed. While the grill is heating gather all of the remaining ingredients because once you start cooking the process goes rather quickly.

Grill the Chicken and Vegetables

Remove the chicken from the marinade and grill 2-3 minutes on each side until cooked through. Add the peppers and onions to the grill (use a grill basket if needed) and grill 3-4 minutes until they have reached your desired tenderness.

Assemble the Fajitas

Add the cooked chicken and vegetables to a serving try and drizzle with the two remaining tablespoons of marinade. Using tongs stuff warm tortillas with the fajita mixture and enjoy!

Serve the fajitas while they are piping hot with any of your favorite fixings! In addition to traditional toppings like sour cream and guacamole some great options are Jalapeno Ranch Sauce, Avocado Bacon Dip, or Smoked Queso! If you are looking for a low carb option you can serve this fajitas on Zucchini Tortillas.

Don’t forget to serve these Fajitas with a tasty margarita! This refreshing Mango Margarita, Spicy Watermelon Margarita, or Keto Margarita will definitely hit the spot!

Storing and Freezing

Store any leftover fajitas in an air tight container for up to 5 days. It is best to allow the fajitas to cool completely before storing. Store the fillings separately from the tortillas to prevent the dish from becoming soggy.

To freeze the fajitas allow them to cool completely and store in a large freezer bag. You can freeze fajitas up to 3 months.


Reheat fajitas in 30 second increments in the microwave until warmed through. You can also use an air fryer when heated to 350 degrees F for 4 minutes.

Fajita FAQ

Fajitas are usually comprised of grilled protein, onions, and peppers. Traditional fajitas do not generally have cheese, but you can use a great Mexican cheese such as cotija. Other toppings include pico de Gallo, salsa, sour cream, guacamole, cilantro, and lime juice!

Yes. This recipe can be made on a gas, charcoal, or electric grill. It also works in a grill pan or griddle. If you don’t have any of those options available you can also use a nice large heavy bottom skillet.
