Chicken fajitas are full of flavor, quick and easy to make! They have a simple homemade seasoning mix, tender chicken and fresh peppers. The toppings are optional but add a great flavor.
On days when we don't have a lot of time for dinner, we like to make quick and easy meals like these! Quite often when I buy chicken breasts, I cut some of it up and freeze it so it is ready for meals like this.
These are pretty simple to make and use a homemade seasoning mix. We try to stay away from too much processed food here!
Chicken - Chicken breasts are best here for texture. As much as I love chicken thighs, they just have an odd texture in fajitas.
Peppers - We recommend using fresh peppers for the best texture and taste, but you can add frozen peppers instead. Frozen peppers are usually get a little mushy when you cook with them but in a pinch they are useable!
Onion - Yellow onions are best here for flavor, but you can use a sweet onion or even a white onion.
Lime - Lime adds a great flavor but it is optional.
Fajita seasoning mix
This easy chicken fajita recipe uses a homemade seasoning mix and it is really easy to make!
- chili powder - No substitutions recommended.
- paprika - You can use smoked or regular. We use regular because we use chipotle but I would use smoked paprika if not using chipotle.
- onion powder - Onion powder is best here for the flavor but you can substitute with a teaspoon of dried minced onion if needed.
- garlic powder - No substitutions recommended. Fresh garlic can be used in it's place, but powder is recommended here. If using fresh garlic, you would add it with the peppers not with the seasoning mix.
- cumin - No substitutions recommended.
- chipotle - Optional but recommended. If not using chipotle, I recommend using smoked paprika. Chipotle in the small amount will not make your chicken fajitas spicy so if you prefer spice, you will want to add some more!
How do you cut chicken breasts for fajitas?
There is no right or wrong way to make them at home! You can make them into thin long slices or you can make them more like little chunks. Typically in a restaurant they are served in thin slices, but we prefer them to be a little thicker here.
Ours look more like chunks then slices. I slice the chicken breast into thin slices but I don't cut the slices in half lengthwise to make them thinner slices. I cut them in half to make them shorter, not thinner so they are more like chunks.
What toppings go on fajitas?
There are many choices for toppings! We like to add a variety of things to our chicken fajitas and here is some of our favorites:
- cilantro lime rice - we love to add rice and this one just compliments all the flavors.
- black beans
- cheese - we recommend 4 cheese Mexican but use your favorite.
- sour cream - Plain or I like to add a little lime juice, salt and cilantro to it for a perfect topping! We have a recipe for it on our Instant Pot taco rice post. It is in the recipe card.
- salsa - Salsa or fresh cut tomatoes.
- hot peppers
- lettuce - We don't use lettuce but I have heard it is good on top!
Add your favorite! Sometimes we add corn too for our daughter who loves making it into chicken fajita rice bowls instead of using a tortilla.
Frequently asked questions
Lime is recommended for flavor but you can leave it out. It is only for flavor and is not used to tenderize the meat.
Yes you can freeze the cooked chicken fajita filling for about 6 months. The peppers may lose a little bit of their texture, but they will still be good. Do not freeze them assembled, but you can also freeze the tortillas separately.
They are typically made on the smaller round tortillas, similar to the ones for soft tacos. We prefer to use the larger tortillas that are usually used for burritos. They work better when you add a lot of toppings.
