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!

  2. 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!

  3. 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??

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

  5. 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! :)

    • 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

    • 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.

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

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

    • @Sue,
      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. @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. Bring me some of those with some chunky salsa Kiersten! Layoooo

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

    • 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!

  10. 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.

  11. It’s in my crock pot as we speak, and smelling SO good! Love crock pot meals! Thanks so much for this easy recipe!!

  12. This recipe is insanely good and super easy. Be sure to use a slotted spoon to serve, and DO NOT discard the juices left in the slow cooker! I just added a little sour cream, pinto beans, corn, and chicken stock–it made a great soup/chili!

  13. Can I use frozen chicken breast?

    • Of course! I only use frozen chicken breasts when I am doing a slow cooker meal, it makes it easier than trying to remember to take meat out of the freezer in the morning!

  14. Does it make the peppers and onions to mushy to cook them all day like this

  15. I am making this for about 15 people, do I need to change the amt of veggies or will it be enough? I think 2 pds will be enough chicken? Thank you for your help

  16. can you use frozen chicken or does it need to be thawed before going in the crock pot?

  17. do ypu really put in a 1/4 cup of taco seasoning? just checking because i was under the impression when i made homeade taco seasoning that you made it intending to use it for a couple of recipes. if i use 1/4 c. i hardly had any seasoning left

  18. Ashley Simpson Whitmore

    Crock pot meals are my favorite! And fajitas are even better! :-)

  19. try topping these with a good tex mex bbq sauce and some Caesar salad its really good trust me on this one

  20. Melissa Morrison Moeller

    I did this last night (again) and just LOVE it. I will say that I made it with YOUR taco seasoning and it was so much better and flavorful! My one question for you though….it took ALL of the seasoning I had made lol. When you make your taco seasoning – what quantity to you multiply it by? Do you triple it? quadruple it? Do share, please!

  21. For some reason I felt like throwing some chicken in the slow cooker with taco seasoning, onion, and bell pepper to make fajitas. I decided to see if there were any recipes and found this one. The only Rotel I have is chili fixins, here’s hoping it works!

  22. I have an extra large crock pot for an extra large family. do you think it would do ok if I double or tripled the recipe

  23. Cooked these crockpot chicken fajitas and the guacamole yesterday! OMG, amazing!!! Thanks for the recipes!!! Will be cooking them again AND trying more recipes! I’m so glad I came across your website!!!!

  24. I have made this twice in the last 2 weeks….once for us (to test it out since this was the first time) and again to take to a family in need of a meal brought to them. As the recipe says, it was super easy and delicious, too! We used leftovers for quesadilla filling….also delicious. I will definitely be making it again and again!

  25. I made this for dinner last night. I added chopped garlic and cilantro to the crockpot . It was amazing. So Yummy. I have never made fajitas and this was so easy to follow. Thanks so much for giving us great recipes
