Expert Tips and Variations

  • You can use any cut of boneless chicken.
  • Slice or shred the chicken.
  • I used a variety of bell peppers for color but also layers of flavor. You can do all the same color if you want.
  • If you do not want to make a homemade fajita seasoning, reach for your favorite packet at the store.
  • The lime and honey adds some tang and sweetness to the fajitas to balance all the flavors.
  • If you want a lower carb recipe, skip the honey and serve over a bed of cauliflower rice, and skip the tortilla.

Recipe FAQs

How to know when chicken is done?

Grab a meat thermometer and make sure the internal temperature of the chicken reads 165 degrees. If it is at that degree, the chicken is fully cooked and safe to eat. The other things to look for is that the juice runs clear, no pink color to the meat. But, using a meat thermometer is a must to ensure the chicken is fully cooked.

How to warm up tortillas for fajitas?

Take your tortillas and wrap them in aluminum foil or use a warmer like this one on Amazon. Turn the oven on to 325 degrees and toss the fully wrapped flour tortillas in the oven. Heat for 10-15 minutes, then carefully remove. The tortillas will be nice and warm and perfect for serving up with your mix.

How long can I store leftovers?

Store the leftover fajitas in an airtight container for 3-4 days in the refrigerator. Anything after you need to use your best judgement. When in doubt, toss out any leftovers that look bad.

Are chicken fajitas healthy?

Chicken fajitas are a healthy option, but you will find the flour tortillas can be higher in carbs and calories. For a healthier alternative reach for a lower carb tortilla.

What goes with chicken fajitas?

You can serve any of your favorite sides with your fajitas. I love a pico de gallo salad next to it, but feel free to do any sides. Our Chipotle Copycat Guacamole, mexican rice, refried beans, are great options as well. 

What can I use instead of cilantro?

Some folks just can’t stand the taste of cilantro.  I read there is a gene that makes some people more susceptible to not being able to stand its flavor.  If that’s you, then you could substitute the cilantro with basil or even parsley depending on what you like.

I hope you love this recipe for Chicken Fajitas in a crock pot as much as I do!  It’s an easy recipe bursting with flavor.
