Crockpot Chicken Fajitas

Slow Cooker Chicken Fajitas

For almost 5 years these Slow Cooker Chicken Fajitas have been one of the most popular recipes on my blog. Because we all love an easy delicious recipe don’t we? This is real life and we are busy people.

With this simplified recipe you get to skip marinating, and you also get to skip sauteing veggies and chicken in batches (and therefor tending to it). Instead here, the crockpot does most of the work.

And not only that, cooking it in the slow cooker allows plenty of time to for the flavors to meld together and really soak into the chicken and veggies, plus it will leave you with perfectly tender chicken every time.

It’s a delicious family friendly recipe and it makes plenty so you may be lucky enough to have left overs for lunch the next day!

Then for the days you didn’t plan ahead for a slow cooker dinner try my Sheet Pan Chicken Fajitas, everything cooks together on one sheet pan. So easy and so good!

Crockpot Chicken Fajita Ingredients

Crockpot Chicken Fajita Ingredients:

  • Boneless skinless chicken breasts – I like to stick with chicken breasts here because thighs will just shred apart.
  • Canned diced tomatoes with green chilies – if you can’t find them with green chilies you can use plain diced tomatoes and add a 4 oz. can of green chilies or just skip the green chilies.
  • Bell peppers – I like to use a trio of red, yellow and green but really any color will work.
  • Yellow onion and garlic – you can also use a red onion if that’s what you have on hand.
  • Chili powder, cumin, paprika, coriander, salt and pepper – these spices give the fajitas that classic Tex Mex flavor, if you don’t have coriander you can substitute Oregano (a much different flavor but also common in fajitas).
  • Lime – use fresh lime juice for best flavor.
  • Honey – this just balances the acidity of the lime and tomatoes but you can omit it if preferred.
  • Tortillas and toppings – toppings are optional but don’t forget the tortillas!

Steps to making chicken fajitas in the slow cooker

How To Make Slow Cooker Chicken Fajitas

  • Top with chicken breasts.
  • Mix together seasonings and sprinkle over both sides of chicken.

Tips And Variations:

  • If you like the bell peppers tender crisp and not soft, wait until about the last 30 minutes to add them.
  • Cook near lesser times if you’d like to slice chicken vs. shredding.
  • For an extra boost of flavor serve topped with sour cream, salsa, sliced avocados or guacamole, or Mexican hot sauce.
  • Use corn or flour tortillas for serving. Warm them first.
  • Or try serving fajita mixture over rice or quinoa and make a burrito bowl instead.
  • Add more or less chili powder according to preference. Be sure to use mild chili powder.
  • Store leftovers in the fridge for up to 3 days.

    This is so good! There is a lot of juice at the end. So I pull everything out of the crock pot, leaving most of the juice behind.

  • Lori

    Super yummy! Followed the recipe but I did add some spicy Dan-O’s seasoning because I like more kick. Served with small flour tortillas, sour cream, freshly grated cheddar and salsa. My husband plans on taking it to work with nacho chips. I will definitely be making this again! Thank you for the easy recipe!

  • Shirl

    Yummy! And makes enough to have leftover Mexican shredded chicken to top salads, nachos, on in quesadillas. Love a good crockpot recipe that yields lots of meat.

  • Ty

    Honestly I have variations of very similar recipe. The fajita packet itself is only for 1 pound and requires only 1/4 cup of water. So 16 ozs of salsa to make up the other pound is very overkill and why you have so much juice. You should use 2 packets at least so the spices are even tasting like a fajita and not a salsa chicken. However I sometimes do 1 packet fajita mix and use enchilada red sauce as my base and do a little extra and its fine as long as you add some cumin, chili powder(or green diced chilis), onion powder, and garlic. A little oregano goes a long way to if you prefer a taco taste. But this is my go to so easy and i use 2 peppers and 2 onions def at least. Try that and follow her directions and i promise you will have made the best fajitas ever!!!

    • TCHinson

      In this recipe, she doesn’t use packets of fajita seasoning. The recipe calls for chili powder, cumin, coriander (or oregano) paprika, salt and pepper. Not sure where you got the idea that she used fajita packets in this recipe.

    • Mike

      Stay in your lane Ty. No need to put your worth in because it isn’t worth anything.

      • BeLikeMike

        Worth using a fajita packet. Pretty bland flavour. Hope Mike finds his lane in one of these recipe boards, for what it’s worth lol.
