Why We Love This Authentic Fajita Recipe
- Great for a crowd: This recipe serves four, but can easily be doubled if you’re entertaining. Set up a fajita bar for everyone to build their own fajitas with all their favorite toppings. It’s so colorful when served!
- Make ahead: The chicken can be seasoned ahead of time and left to marinate, but if you want to cook it all up in advance, the leftovers are pretty tasty too!
- So easy! This is one of my go to family-friendly recipes for a reason. There’s minimal prep and because it’s made in one pan, clean up is a breeze! Isn’t that everyone’s dream come true?
- Packed with protein: All that chicken is loaded with protein, plus you get a nice serving of veggies, too. It’s a great, balanced meal and can accommodate a range of dietary needs!
Ingredient Notes
For the Fajitas:
- Chicken: Chicken is a great source of lean protein. I typically use boneless skinless chicken breasts, but this recipe also works great with chicken thighs and tenders.
- Fajita vegetables: Bell peppers and onion add lots of flavor and color to this dish. I typically use red, yellow and green peppers, but you can use any color you like. You can also use red onions instead of yellow.
- Lime: Fresh lime juice adds a delicious zingy flavor. Use fresh rather than bottled for the best results. (Bottled lemon juice can work in a pinch!)
- Oil: For marinating and cooking. I generally use olive oil, but canola or avocado will work well too.
For the Homemade Fajita Seasoning Mix:
You can easily whip up your own fajita seasoning from scratch using a few basic spices:
- Chili powder
- Garlic powder
- Smoked paprika
- Onion powder
- Cumin
- Oregano
- Salt and pepper
How to Make Mexican Chicken Fajitas – Fajitas de Pollo
- In a large bowl, combine sliced chicken breast, one tablespoon of olive oil, juice of half a lime and the fajita seasoning spices. Toss the chicken until it’s evenly coated in the marinade. If you have the time, allow the chicken to marinate for at least 30 minutes.
- When ready to cook. Heat one tablespoon of olive oil over medium-high heat in a large non-stick heavy skillet or cast iron skillet. Add half of the chicken strips to the hot skillet and sear until just cooked, about 3-5 minutes.
- Remove from the pan and set aside. Repeat with remaining chicken. Set chicken aside in a bowl or on a plate.
- Add the remaining tablespoon of oil to the pan. Add sliced onion and cook for 2 minutes. Add in sliced peppers and cook an additional 2-4 minutes or until they start to soften.
- Add chicken back to the pan and toss to combine.
- Squeeze additional lime juice over the mixture.
- Serve warm over flour or corn tortillas with desired toppings.

Expert Tips for the Best Fajitas
- Be sure to cut all the vegetables and chicken in strips that are roughly the same size to ensure everything finishes cooking at the same time.
- If you want to save on prep time, you can purchase pre-sliced raw chicken tenders.
- If you have extra time, I highly recommend marinating the chicken in the marinade for at least 30 minutes to infuse even more flavour into the fajitas.
- If you like to make this recipe on repeat, I recommend making up a big batch of this authentic fajita seasoning recipe. Skip the seasonings in the recipe card and simply add 1 1/2-2 tablespoons of this mix. You can also use taco seasoning (homemade or store-bought) as an alternative to the homemade fajita mix, but I recommend adding a little bit of extra ground cumin if you have some on hand.
- To make the fajitas more kid-friendly, you can soak the onions in cold water while prepping the rest of the ingredients to take the bite out of them.
- Be sure to coat all of the vegetables and chicken evenly with the olive oil, lime juice and seasoning mix. I typically toss and massage the chicken and fajita marinade with my hands so that everything is flavored equally.

Storage & Reheating Guidelines
Refrigerator: The cooked Mexican chicken fajitas and pepper mixture will keep well in the fridge for up to 3 days in an airtight container.
You can also store the fajitas already made, but I prefer to heat up the chicken mixture separately and serve it in fresh warm tortillas to prevent them from going soggy in the fridge.
To reheat: Reheat the leftover chicken mixture in a skillet on the stovetop until warmed through.
You can also reheat the already made fajitas on a baking sheet in the oven at 360F for 10 to 15 minutes. Cover with foil to prevent them from drying out.
How to Freeze Chicken Fajitas
If freezing from raw: Toss the raw marinated chicken strips in a larger freezer safe bag and freeze for up to 3 months. Allow to thaw in the fridge for at least 24 hours before cooking.
To freeze from a cooked state: Let the chicken and pepper mixture cool and then place in a large freezer bag and squeeze out as much air as possible. The mixture can be frozen for up to 3 months and should be thawed for at least 24 hours in the fridge before reheating.
Recipe FAQs
Yes, chicken fajitas make a great healthier option, especially if you make a few simple swaps! By preparing the fajita seasoning mix from scratch, you can control the ingredients and amount of sodium used, making them a much healthier alternative to the store-bought mix.
The chicken is also a source of lean protein and iron, while the fajita veggies offer fibre and lots of vitamins and minerals, making fajitas a balanced and nutrient-rich option.
Sure! I love the flavor of fajita seasoning, but you can easily use taco seasoning if you prefer. Taco seasoning tends to have more chili powder while fajita seasoning has more cumin so it has a slightly different flavor, but still works well.
Yes! I actually love making chicken fajitas with chicken thighs since they are naturally tender when cooked. Paired with the fajita mix, the end result is delicious and juicy chicken.
To use chicken thighs, cut the raw thighs into strips or pieces, marinate in homemade fajita mix and cook up on the stove. You can also grill or bake the thighs whole after marinating then slice into thick slices to serve on warm tortillas.
For the best results, I prefer to serve the fajitas fresh, but you can prepare the chicken mixture and fajita mix in advance and marinate the chicken strips up to a day or two in advance and cook it up right before you’re ready to serve.
If you’d prefer to do some meal prep and cook it all up in advance, the mixture still tastes delicious when made ahead of time.

Super easy and so delicious, I double the marinade and added quartered roma tomatoes. Served charro beans and lime rice along side.Thank you for a plate of happiness .
That sounds amazing!! Love the serving suggestions…now I’m totally craving your plate of happiness haha!
I just made these with a couple of modifications. I actually doubled the spices and olive oil for the marinade. The only other change was that I added Roma tomatoes cut into lengthwise wedges to my iron skillet along with the bell peppers…absolutely delicious!
Love it! I bet they were super flavorful with the extra seasonings and tomatoes. Will try that next time!
I made this without the chicken. I think it needs more vegetables if you’re going to do that maybe some mushrooms yellow peppers. also I used a knife to ream the limes. I wouldn’t do that again it came out very sour. but overall this was genius rubbing the seasonings and oils into the vegetables with your hands and letting that marinade with the lime juice. that is the secret to authentic Mexican fajitas. mine never came out right the way they are at the restaurant and that is why. I’m looking forward to making this again with chicken and without the lime flesh. Also I did not use salt because of dietary reasons. I’m sure it tastes amazing with the salt. thank you for sharing this this one recipe I’m writing down on a card.
So happy you enjoyed the recipe even without the chicken! Thanks so much for sharing your tips! Glad it’s a keeper :)
