Chicken Fajita Ingredients

The full recipe is at the bottom of this page, but here's a quick overview of what you'll need and how to make it:

1 - 1.5 pounds boneless, skinless chicken breasts
3 bell peppers (red, green, yellow), sliced
1 white onion, sliced
3 tablespoons olive oil, divided
2 teaspoons cumin
2 teaspoons chili powder
½ teaspoon garlic powder
1 teaspoon salt
¼ teaspoon pepper
Juice of 2 limes, plus more for serving

How to Make Chicken Fajitas

Step 1: Make the marinade

In a medium bowl, stir together 1 tablespoon oil, the juice of 1 lime, cumin, chili powder, garlic powder, salt, and pepper.

Step 2: Toss the chicken in the marinade

Add the sliced chicken to the bowl and toss to coat.

Step 3: Cook the chicken

In a large saucepan over medium high heat, add 1 tablespoon oil. Add the chicken in a single layer and cook for 3 - 4 minutes on each side, until cooked through.

Cook in batches and add more oil if necessary. Set the chicken aside and drain any excess liquid from the pan.

PRO TIP: Be sure not to overcrowd your pan with the chicken. I usually cook mine in 2 batches. If you overcrowd your chicken it won't brown properly.

Step 4: Cook the peppers & onion

Heat 1 tablespoon oil and then add the onion and pepper to the pan. Cook, stirring frequently, for 6 - 7 minutes, until tender.

Step 5: Add chicken

Stir the chicken back into the pan and cook for 1 - 2 minutes more, until heated through. Remove from heat and squeeze the juice of 1 lime over the pan.

Step 6: Serve & Enjoy!

Serve immediately, optionally with tortillas, lime wedges, and toppings (avocado, pico de gallo, cheese, sour cream, etc.).

Ingredient Notes

Seasonings: this recipe uses a quick homemade fajita seasoning mix. In a pinch, you could also use taco seasoning or a store-bought fajita seasoning packet.

Bell peppers: I like to use a mix of red, green, and yellow bell peppers but you can use any color for this recipe.

Spice: this recipe has a low spice level as it's written; to make your fajitas a little spicy sprinkle some cayenne pepper into your marinade.

Frequently Asked Questions

Do you have to use a cast iron pan?

It's not necessary to use a cast iron pan, but it can help give the chicken a nice sear and flavor. I like this beginner-friendly 10" Lodge Cast Iron Skillet.

How do you cut chicken for fajitas?

To cut the chicken for fajitas, slice it in thin strips that are about ½ inch thick. For this recipe, you'll slice your chicken before cooking it.

How do I know if my chicken is cooked?

Because you'll be cooking thinly sliced chicken, it will cook fairly quickly. Cook the chicken for 3 - 4 minutes on each side and then test a piece to see if it's done: there should be no pink in the middle and it should be cooked through to 165°F.

Storage

In the fridge: cool and store your leftovers in the fridge in an airtight container for up to 3 - 4 days.

For meal prep: this is a popular recipe for meal prep because leftovers are tasty and last for several days. Cook your fajitas and meal prep them with a side of veggies (like beans or lettuce) or rice in serving-size containers.
