Easy Chicken Fajitas
With Southwest-inspired flavor, strips of chicken, bell peppers, and onion are wrapped up in warm tortillas to make these Easy Chicken Fajitas.
Finish each one off with a squeeze of lime and a scoop of sour cream or guacamole. This is a dinner that never fails to make everyone smile.

I made this today and my husband said at least 5x, ” This is so good!”. I didn’t use taco seasoning, I used fajita seasoning and followed the recipe as is. It came out so good! and it didn’t take long either. Will definitely be making again! Thank you!
Easy Fajita Ingredients
- chicken thighs or breasts, cut into strips
- taco seasoning
- onion, sliced into strips
- bell peppers, sliced into strips
- optional: lime juice, sour cream, or guacamole

Taco vs Fajita (aka What is a fajita?)
Originally, “fajita” was used to describe the cut of beef (a skirt or “fajita” steak) used in traditional fajita recipes. Today, that is no longer the common definition and the word fajita is used in the U.S. to reference all kinds of fillings, like chicken, pork, or seafood.
The meat in fajitas is usually combined with strips of sautéed or grilled peppers and onions. The meat and vegetable mixture is typically served alongside a stack of warm tortillas.
When ready to eat the fajitas, you’ll fill each tortilla with the warm meat and vegetables along with the optional toppings of your choice. So, technically, you’re making chicken fajita tacos.
However, most of the time when making tacos, the vegetables are chopped and served raw as a topping for each taco. Tacos and fajitas can be prepared all at once or individually assembled by each person.

Chicken Fajita Tacos
- Combine the chicken, 1 tablespoon of oil, and 2 tablespoons of taco seasoning in a mixing bowl. Toss well to thoroughly coat.
- In a large non-stick skillet, heat the remaining oil over medium heat. Add the chicken and cook, while stirring constantly, for about 3-4 minutes. Transfer the cooked chicken to a plate next to the stove.
- Add the onion and bell pepper to the hot skillet. Cook until slightly crisp and still tender, tossing gently with tongs periodically. Sprinkle with remaining taco seasoning.
- Return the cooked chicken to the skillet and stir to combine. Serve immediately with tortillas. Squeeze lime over the chicken mixture and top with sour cream and/or guacamole as desired.

I’m a big fan of easy dinner recipes that can be made with just a few ingredients. Meals like Sweet and Spicy Chicken Stir Fry, BBQ Meatloaf, Cheesy Sausage Pasta, Crockpot Sweet and Sour Meatballs, Mexican Pulled Pork, and French Bread Pizza are all things that can be pulled together with very little effort.
Chicken Pot Pie Casserole with Biscuits takes a bit longer but is downright mouthwatering with its piping hot filling of tender chicken and vegetables, topped with flaky, golden-brown biscuits.

I added chicken broth and it comes out really juicy
That’s a great tip. A small splash can help with that, just use caution not to add too much and accidentally boil the chicken strips.
So easy and so yummy! This will go on our favorites list!
I’m thrilled that you enjoyed the fajitas!
How far in advance? Fridge for how long?
I tried this tonight for the first time and my family loved it. It’s quick and easy and most ingredients I keep on hand. I definitely will make it again.
I’m so glad you like the fajitas!
Can you cook this ahead and put in crockpot to get warm or does it get too soggy?
The chicken may get too soft with the extended cook time.
Great flavor, don’t skip the lime! Easy one skillet dinner.
I’m thrilled that you enjoyed the recipe!
I made it tonight. Very easy, look good and taste very good. I didn’t have lime, so I use lemon juice.
Thank you.
