How To Make Chicken Fajitas

See the recipe box below for ingredient amounts and full recipe instructions.

Melt butter in a medium skillet over medium-high heat. Season the sliced chicken with salt and pepper, then cook for about 6 minutes until fully cooked through. Transfer the chicken to a plate, cover, and set aside.

In the same skillet, add a little more butter or olive oil if needed, and sauté the onions and bell peppers until softened and fragrant.

To assemble, place the cooked chicken and vegetables in a warm tortilla. Add toppings like shredded cheese or sliced avocado if you like.

Pro Tip: Keep the chicken simply seasoned with salt and pepper, or boost the flavor with a sprinkle of your favorite taco seasoning.

Tip: For an even easier method, try making Sheet Pan Chicken Fajitas. Bake the chicken and vegetables together on a single sheet pan for even cooking and bold flavor. See our Sheet Pan Chicken Fajitas recipe for full step-by-step instructions.

Expert Tips

  • Cook Separately: Cook the chicken and vegetables in stages for the best texture and flavor.
  • Slice Evenly: Cut onions and peppers into similar sizes so they cook evenly.
  • Add Pineapple (Optional): Toss in small chunks of pineapple for a touch of sweetness and freshness.

Frequently Asked Questions

How do I know when the chicken is fully cooked?

The chicken should be cooked through and no longer pink in the center. It should reach an internal temperature of 165°F (74°C).

Can I make chicken fajitas ahead of time?

You can cook the chicken and vegetables ahead and store them separately in the refrigerator. Reheat and assemble when ready to eat.

What’s the best way to reheat chicken fajitas?

Reheat the chicken and vegetables in a skillet over medium heat until warmed through, or microwave them in short 30-second bursts, stirring in between.
