Jump to:
Mexican food is one of my most favorite types of food, and I make it a lot! These chicken fajitas have been one of my go-to recipes forever. They're made totally from scratch - no seasoning packet needed - and are so simple yet so incredibly delicious!
First, you make a quick marinade for the chicken. THIS is where all the flavor comes from! The best part? You don't even have to marinate the chicken for a long time. You just let it sit while you're cooking the peppers and onions.
After you cook the peppers and onions, you cook the chicken with all that super yummy marinade. Then you add back the peppers and onions and mix everything together. That's it! You're done!
Your kitchen will smell sooo good while you are cooking these fajitas!

Ingredients You Need
- Olive oil
- Lime juice
- Garlic
- Chili powder
- Cumin
- Salt and pepper
- Boneless skinless chicken breasts
- Red bell peppers
- Onions
- Flour tortillas (taco-sized)
- Toppings of your choice
How to Make Skillet Chicken Fajitas


The flavor that the quick marinade gives these chicken fajitas is so much better than any seasoning packet I've ever used. Once you try it, I'll bet you'll never want to use a packet again! If you want to spice things up a bit, add some cayenne to the marinade.
Now, fajitas aren't complete without tortillas! I like to use smaller tortillas (the 6 to 8-inch taco-sized ones) because I think they make the fajitas easier to handle, but use whatever size you like.
AND...if you really want to take these fajitas over the top in deliciousness (which you do, right?), make some of my Easy Homemade Flour Tortillas. I am telling you right now, you have got to try them with these fajitas! You will not believe the difference a homemade tortilla makes!
Then there are THE TOPPINGS! Toppings make everything even better! We keep it pretty simple with sour cream, cheese, and salsa (try my Quick & Easy Homemade Salsa), but homemade guacamole would be good, and maybe some chopped fresh cilantro or lime juice.

I hope you try this Skillet Chicken Fajita recipe and love it as much as I do. Thanks for visiting today!

📋Recipe
Skillet Chicken Fajitas
Ingredients
MARINADE:
- 1 tablespoon avocado oil
- 1 tablespoon lime juice
- 1 clove garlic, finely minced
- 1 teaspoon chili powder
- ½ teaspoon cumin
- ½ teaspoon salt
- ¼ teaspoon black pepper
FAJITAS:
- 1 pound boneless skinless chicken breasts, cut into thin strips
- 1 tablespoon avocado oil, divided
- 1 medium red bell pepper, sliced into thin strips
- 1 medium onion, sliced into thin strips
- salt and pepper, to taste
- 8 6 to 8-inch flour tortillas, warmed
- toppings of your choice
Instructions
- In a large bowl, whisk together the marinade ingredients until well combined.
- Add the thinly sliced chicken to the bowl with the marinade; stir until the chicken is evenly coated. Set aside and let marinate for about 10 to 15 minutes while you prepare the peppers, onions, tortillas, and desired toppings.
- In a large skillet (I use a 12-inch cast iron skillet), heat ½ tablespoon of avocado oil over medium-high heat. Add the peppers and onions, season with salt and pepper, and cook, stirring frequently, until they are crisp-tender and just start to get a little bit of brown color on them.
- Remove the peppers and onions from the skillet to a bowl or plate; set aside.
- In the same skillet over medium-high heat, add the remaining ½ tablespoon of avocado oil. Add the chicken and the marinade and cook, stirring frequently, until the chicken is lightly browned and cooked through (minimum internal temperature of 165°F).
- Add the peppers and onions back to the skillet with the chicken and mix to combine. Cook for a minute or two just to make sure everything is warmed through. Taste and season with salt and pepper, as needed.
- Place ⅛ of the chicken mixture on each warm tortilla, top with your desired toppings, fold or wrap up, and enjoy!
Notes
- Suggested toppings: sour cream, cheese, salsa or pico de gallo, guacamole, fresh cilantro, lime juice.
- Calorie estimate is for two fajitas per serving (chicken mixture and tortillas) and does not include any toppings.

This came out great. I added a little sugar to the marinade for a little sweet tang. Bingo, this is a keeper.
