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

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.
