My husband Tommy is a creature of habit. Anytime we eat at a Mexican restaurant, he always orders chicken fajitas. When we went to Mexico years ago, he may have ordered them almost every night! I find it amusing because I get bored of eating the same thing twice. I tend to always try something completely new to me. If you love fajitas but want some variety, try my Spicy Breakfast Fajitas, Grilled Steak Fajitas, and Shrimp Fajitas.

These healthy chicken fajitas are a regular in my home. We make them at least once a month, and the whole family enjoys them. When Madison was younger, she only liked her bell peppers raw, so I would chop some up and set them aside for her with some chicken and a tortilla. Fajitas are easy to deconstruct if your kids like to eat their foods separately.

How do you make chicken fajitas from scratch?

These easy chicken fajitas cook in about 20 minutes, making them perfect for a busy night. 

I marinate the chicken for 15-30 minutes using my favorite chicken fajita seasoning: chili powder, salt, pepper, garlic powder, and cumin combined with lime juice. I mix the peppers and onions with olive oil, salt, and pepper.

If you want to cook everything on an outdoor grill, put the peppers and onions in a cast iron skillet. If you don’t have a grill, just cook the chicken on a grill pan and the vegetables in a skillet on your stove.

Once the chicken is cooked, slice it into strips and combine with the peppers and onions. Put the mixture in a tortilla along with any other of your favorite fajita toppings.

What topping go on fajitas?

The most popular toppings for fajitas are grilled onions and bell peppers, but they’re also commonly topped with shredded cheese, pico de gallo, guacamole, and sour cream. 

What do you serve with chicken fajitas?

Mexican chicken fajitas are usually served with rice and beans, but corn is another great side. If you’re looking to keep the carb count down, cauliflower rice is an excellent option. And don’t forget the margaritas!

Beans: Instant Pot Black Beans, Mexican Pinto Beans with Queso, Instant Pot Refried Beans

Rice: Mexican Brown Rice, Mexican Cauliflower Rice, Instant Pot Cilantro Lime Rice, Cilantro Lime Cauliflower Rice

Corn: Warm Mexican Corn Salad, Corn on the Cob with Chile and Lime, Corn Tomato Avocado Salad

Chicken Fajita Variations:

  • To save carbs, use a big lettuce leaf instead of a tortilla to wrap around the fajita fillings. You can also serve the chicken and veggies over lettuce as a salad. Add fresh avocado and use salsa as a dressing.
  • Swap the chicken for skirt or flank steak.
  • For a healthier substitute for sour cream, try plain Greek yogurt.

  1. Any ideas if you are trying to cut the carbs on what to serve with these?

  2. Hi! Wondering what the calorie count is without tortillas as those vary by brand. 


  3. I only get the correct calorie count if I use four tortillas instead of eight. 

  4. When I calculate 8 low carb tortillas on MyFitness Pal at 80/90 calories each for the serving size for four, it’s more like 359 calories. Two tortillas alone would be about 180 calories so I don’t know how all the other ingredients only amount to another 119 calories. I’m confused. 

  5. I know fajitas aren’t a novel idea but they are something I never think to cook up at home. And my hubby and I are HUGE fans of all things Mexican! I cooked these up tonight and they are DELICIOUS! I ate 3 and I’m stuffed!  My hubby is still going strong! All I changed was I did onion, red pepper, green pepper, yellow pepper and orange pepper- I went pepper crazy. But they are so beautiful and colorful I just love cooking with them! Thank you for such a delicious recipe!! We will def be making these again! 🙂

  7. Sounds great and I will definitely try this. Could work with steak too!

  8. Found this recipe, bought all of the ingredients, and I've been looking forward to it ALL DAY! And I was not let down 😉 Absolutey delicious!

  9. Gina, I used the recipe builder and got 7pp with the cheese (but not the sour cream or guac). What are you including to get to 8?

  10. Single Cooker! Made this and had left overs. I decided to take the left overs and put over a bed of lettuce and Salsa for the dressing. BEST SALAD EVER

  11. Superb chicken recipe. I love it because it is one of the best healthy dinner recipes for me all the time.

  12. a regular in the home but you eat it once a month? does that make snese?

  13. I made these last night for the family! First time making fajitas and not using the 'boxed' spices, it was delicious and the whole family loved this!!! Thanks Gina 🙂

  14. Gina, you rock!!

  15. These were AMAZING! I used a big piece of romaine lettuce for my tortilla. PERFECT! Love your recipes!! Thank you!

  16. We are trying this meal today for lunch. The chicken tastes so good and its really juicy too!! We plan to make it again! Thank you for sharing!!

  17. I made this this week and it was delicious. I didn't use the tortilla shells I didn't have any in stock in my cupboard, so I had it over rice excellent. I will try it with tortilla shells next. But over rice was a good change too. Thank for the easy to do recipe.

  18. Made this this evening and it was awesome. I didn't even use the tortilla shells because the flavor is so great that I didn't think it needed anything but a small amount of cheese. I was introduced to your site 4 days ago and have already made 3 recipes. THANK YOU for sharing such great recipes with the world!

  19. Gina – if I am going to measure out a serving of the chicken/peppers on my food scale, is it safe to assume 1 serving = 8oz when weighed?

  20. This recipe was a crowd pleaser in my house tonight. My girls love raw peppers and finally started eating n them cooked. Added some of the extra spices to the veggies too.
