Ingredient Notes

  • Chicken: Cut the chicken into uniform pieces across the grain for a more tender bite, or use a package of pre-sliced chicken stir-fry.
  • Bell Peppers: A colorful mix of bell peppers adds classic fajita flavor and visual appeal. Combine red, yellow, orange, or green peppers with sliced onions for a vibrant, delicious filling.
  • Onion: Choose yellow, white, or red onion and slice from top to bottom so the strips hold their shape when they are sautéd. 
  • Fajita Seasoning: Use a packaged seasoning, or my homemade fajita seasoning. Be aware that packaged seasoning mixes may contain a lot of sodium, so don’t add extra salt in this case.
  • Flour Tortillas: Choose large tortillas that can easily fold around the filling. You can try corn or grain-free tortillas, just know smaller tortillas will require less filling.

How to Make Chicken Fajitas

  1. Sear the chicken, then set aside.
  2. Cook the onions and peppers with seasoning and water.
  3. Return the chicken and cook until tender. (Full recipe below.)
  4. Warm tortillas, fill, and top as desired.

Chicken Fajita Success Tips

  • Cook in a roomy skillet, leaving plenty of space around the ingredients to encourage proper browning.
  • Once the chicken is done, remove it promptly from the heat and add it back briefly at the end to warm through.
  • Heat the tortillas right before eating and cover them with a clean kitchen towel to help retain their warmth and softness.
  • Top with sour cream, guacamole, salsa, shredded cheese, chopped fresh cilantro, and a squeeze of lime.

Got Leftovers?

  • Let the filling cool completely before storing it in a sealed container in the fridge for up to 4 days. Keep tortillas and toppings separate to preserve their texture.
  • Reheat the chicken and vegetables gently in a covered skillet with a little water, or for short intervals in the microwave. Be careful not to recook the chicken.
  • Give leftovers new life by adding them to quesadillas, burrito bowls, salads, omelets, nachos, or chicken taco soup.
