Easy Slow Cooker Chicken Fajitas- 4 ingredient chicken fajitas slow cook in the crock pot all day long to create a satisfying, delicious meal without much effort!

If you’ve been following CenterCutCook for any amount of time, you’ve probably already determined that I have a thing for fajitas. My love for fajitas all started when I came across a phenomenal marinade and posted about “The Best Fajitas” I had ever had in my life!

My love for fajitas continued to grow when I tried a new recipe for Sizzling Chicken Fajitas that blew my socks off! My fajita love didn’t stop there though…. next I took that recipe and turned it into a not-to-be-missed version of Chicken Fajita Quesadillas. What can I say? I adore fajitas with tender spicy meat and veggies, topped with all of my favorite garnishes.

With cooler temperatures right around the corner in Chicago, I began to realize that it’d probably be in my best interest to come up with a way to enjoy fajitas without needing to fire up the grill in sub-zero temperatures. I debated between trying to make them in the oven, or experimenting with my slow cooker. I am always looking for new chicken recipes and ways to use my crock pot, so naturally, I decided my slow cooker would be the best option here!

The method is truly simple. Dump everything into the slow cooker, turn it on low, walk away and 8 hours later you have perfectly tender chicken fajitas! Does it get much easier than that? There’s no marinade involved here, instead the meat will get seasoned with a packet of taco seasoning (or make your own – my homemade taco seasoning recipe here) and a can of Ro*Tel which is simply diced tomatoes with green chiles and some seasoning.

Right before you’re ready to eat, you’ll remove the chicken from the slow cooker and use two forks to shred it. Once shredded, you’ll return the chicken to the slow cooker and stir it together with the veggies. There will be a substantial amount of liquid in the slow cooker, so be sure to use a slotted spoon to serve up the chicken and veggies so that you aren’t left with soggy tortillas.

Be sure to top these fajitas with my homemade guacamole and salsa! One bite of these tasty Easy Slow Cooker Chicken Fajitas will send you to fajita paradise! Enjoy!

  1. Ro-Tel. The miracle ingredient. I love that stuff! I am a Mexican food lover.This looks SO delicious!!!! And easy. I like easy!

    • I use Ro-Tel in so many recipes! It’s perfect for adding just the right amount of heat to a recipe! And yes, easy is awesome! :)

    This was delicious, and so easy. After removing the chicken, I blended the juices with an immersion blender and served it as a sauce, along with sour cream and red and green salsas. Family loved it! We’ll be enjoying this often!

    • What a great idea Mari, thanks so much for the tip! I really appreciate the feedback. :)

    • KayLynn

      You can also used the left over liquid and 1/3cp chicken broth and make Spanish rice for the side. It makes GREAT rice!

    • Dana

      Can you cook the veggies from the beginning in the crock pot? I don’t like crisp veggies, but was worried they’d be too soggy.

  3. Julia B

    Ok so I never use my crock pot but I really want to. I read the recipe for the chicken fajitas and I’m just wondering do I add water to the crock pot or do I just let it slow cook in the Ro-tel sauce??

    • No, you do not add water. Between the juices from the Ro-tel and the natural juices of the chicken, there will be plenty of liquid.

    I love this website!! Amazing recipes! simply love it!

    My hub had gotten me a crockpot a while ago and I’m afraid to take it out of the box. I’ve never crock-cooked before. But having some tempting recipes might help! :)

    • Faye Fraser

      my ex bought me one for christmas one year, i cook whenever i can in it. Once you go crock you never go back lol

    • Mary Pat Walsh

      Oh Sue…you need to take it out and try it. It will be your new best friend. It’s so easy and leaves you so much time to do something else. Not to mention the lack of dishes.

    • Sue Bogan McNally

      Thanks so much ladies! I just need to clear a spot on the counter :)

    • Sarah Sue

      Sue, Take the crock pot out and use it. I use mine all year long. From Baked potatoes to whole meals. <3

    • KayLynn

      Try pulled pork and green chili tacos for a great slow cooker recipe too.
      A pork roast, a can of green chili diced, an onion diced and 1/4cp of water or stock. Set it low and cook until the pork shreds. I like this with a Mexican coleslaw (or just your regular taco toppings) on fried corn tortillas. YUMM!!

  6. Janis Consolver

    @Sue, I’m finding other recipes in addition to this site, on a FB site called Crock Pot Moms. I’m using my crock pot nearly 5x per week!

  7. Carrie Obermayer

    Bring me some of those with some chunky salsa Kiersten! Layoooo

  8. Morgan May

    why is it considered 4 ingredient when it lists 6 (7 if you include the tortillas) in the recipe?

    • KayLynn

      Because the veggies all count as one. You can actually buy onions and peppers already cut up into containers at the store.

  9. If you were to make this with beef instead of chicken what would be you choice of beef to use…..Love Chicken but my husband loves beef so I try to make it fair!

    Trying this right now. I’m happy to have a homemade taco seasoning recipe now. I’ve always bought packets but have become increasingly unhappy with the amount of junk in them. I’ll let. You know how it goes.
