Years ago I got this recipe for Slow Cooker Chicken Fajitas from a blog called MomFood, written by a blogger named C. Jones who graciously agreed to let me republish it here. That blog disappeared shortly after I got the recipe, although C. Jones did leave a comment on the original post in 2006. At the time she was still reading Kalyn’s Kitchen, so if she’s still reading now, I hope she’ll be pleased to see this. I’m trying to update my oldest posts that don’t have photos, so today I made fajitas in the crockpot and took a few pictures.

Of course, I know these chicken fajitas made in the slow cooker aren’t really fajitas like the ones that come on a sizzling plate at a restaurant, but this recipe is still pretty delicious even without that fajita sizzle. These easy-to-make Chicken Fajitas are delicious any time of year, but I especially love to make this in the summer, because using the slow cooker will keep your kitchen cool.

The chicken and roasted veggies are delicious served in low-carb tortillas or over cauliflower rice, but truthfully rice or tortillas are completely optional. I like to eat this just piled up on a plate with melted cheese, salsa, and a dollop of sour cream. Some Cilantro-Lover’s Guacamole would go great with it too, but unfortunately there was none of that left for the photo!

What ingredients do you need for this recipe?

  • boneless skinless chicken breasts
  • red onion
  • red bell pepper
  • green bell pepper
  • Chili Powder (affiliate link)
  • ground cumin (affiliate link)
  • salt
  • chicken broth
  • fresh-squeezed lime juice
  • low-carb tortilla, I like Mission Carb Balance Low-Carb Tortillas (affiliate link) 
  • Mexican four-cheese blend
  • sour cream
  • guacamole
  • salsa
  • (Could also add lettuce and tomato.)

Can this recipe work for Keto?

You can easily make this recipe Keto friendly by simply serving the chicken and veggies on a plate, topped with melted cheese. I’ve eaten it that way many times and always enjoyed it! This variation would also be gluten-free.

What size slow cooker did I use?

I used an old Crock-Pot 2.5-Quart Slow Cooker (affiliate link) for this recipe, but as you can see it was quite full and a larger slow cooker would definitely work.

Slow Cooker Chicken Fajitas

Slow Cooker Chicken Fajitas

Yield 6 servings
Prep Time 30 minutes
Cook Time 6 hours
Total Time 6 hours 30 minutes

Slow Cooker Chicken Fajitas are a delicious meal for any time of year.



  • 2 lbs. boneless skinless chicken breasts (see notes)
  • 1 onion, thinly sliced (I use red onion)
  • 1 red bell pepper, sliced in half-circle slices
  • 1 green bell pepper, sliced in half-circle slices
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1/4 teaspoon salt
  • 1/2 cup chicken broth (see notes)
  • 2 tablespoons fresh lime juice (more or less to taste)

For Serving

  • flour tortillas (I use low-carb tortillas)
  • grated cheese (I use Mexican four-cheese blend)
  • sour cream
  • guacamole
  • salsa
  • (Could also add lettuce and tomato.)


  1. Trim all visible fat and tendons from chicken breasts, and cut chicken into 1 inch crosswise slices.
  2. Place chicken in crockpot
  3. Cut both ends from onion, then peel, cut in half top to botton, and cut into half-circle slices.
  4. Add onion to crockpot.
  5. Cut ends from red and green bell pepper, cut in half top to bottom, remove seeds and membranes, and cut into half-circle slices. (Cut up the stem and bottom end too.)
  6. Add bell peppers to crockpot.
  7. Squeeze lime juice over chicken, onions, and peppers in crockpot.
  8. In a small bowl stir chili powder, cumin and salt into chicken broth (I used homemade chicken stock).
  9. Pour over chicken.
  10. Cover and cook on low for 6-7 hours or on high for 3-4 hours, or until tender. (I usually cook about 3 hours on high.)
  11. Spoon chicken and vegetables into warmed tortillas (I use low-carb tortillas) and serve with toppings. This would be great with Cilantro-Lover’s Perfect Guacamole.
  12. This is also delicious just served on a plate, with cheese melted over and other toppings added.


You need about 4-5 chicken breasts to make six servings. I used homemade chicken stock but canned chicken broth or chicken stock from a carton would be fine for this recipe.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If you serve these Chicken Fajitas with low-carb tortillas or over cauliflower rice, this can be a low-carb meal. If you’re serving this with low-carb or whole wheat tortillas, it would be a great meal for phase 2 or 3 of the original South Beach Diet. Just eat the chicken and veggies topped with some cheese without tortillas or rice for stricter low-carb or Keto.

    Liked the beet post on bloggher too!

  3. Was it the weekend when it was happy?

  4. That’s such a good idea! I would love to have some fajitas waiting for me after a long day of work. What can’t you do in a slow cooker?!? Wait, don’t answer that 🙂


  5. I love the idea of making fajitas in a crock pot! 🙂 Great recipe.

  6. I recently picked up a slow cooker and I have been itching to try it. I like the sound of making fajitas in a slow cooker.

  7. MandyCat, it’s easy and tasty. You’ll be glad to know the porn site is gone and momfood.blogspot.com is now the blog of another mom (but not C. Jones.)

    Cyndi, love the idea of doing it with beef. Do you partly cook the beef first before adding the veggies?

    Pearl, it’s a keeper!

    Katrina, you *must* get a crockpot! So handy.

    Melynda, if you’re using frozen peppers I might cook the other ingredients a bit before adding the peppers. Let me know how it turns out.

    Cheryl, so glad you like it.

    Junglefrog, just wish I had some guacamole left to eat with it. Need to make some more!

    Hi C. Jones! So fun hearing from you again. Thanks for reading all this time. Hope you’re doing well.

  8. Of course I’m still reading your blog Kalyn 🙂
    The photos are so beautiful!!! I still make these regularly, and the recipe scales well to feed a crowd.

  9. Ah that is so kind of you to share this lovely recipe to go with the guacamole…:) I will definitely be making this!!

  10. ooh, I’m so looking forward to this. It’s just what I am looking for!

  11. This sounds great. I have peppers in the freezer ready to go!

  12. Ohhhhh, that looks wonderful! OK – now you got me going to buy a crockpot today:)

  13. that sounds like a great recipe for crockpot!

  14. You suggested once a long time ago to try it with beef – so I use skirt steak (some call it flap meat), cut across the grain – and it comes out fabulous! We eat this often since it’s sooo good and so easy.

  15. I’m certainly going to try this. It sounds like a really good addition to my crockpot repertoire.

    The information about the porn site that has taken over the Momfood blog reminded me of an episode several years ago. I was trying to find a recipe for oven baked potatoes made with onion soup mix. Somehow I wound up on a site that bragged about being the “nastiest sex site on the Internet” and from a very brief glance at the photographs, rightfully so. Worse, it wouldn’t let me log off. I had to power cycle my PC to escape.

  16. Very fun hearing from you C. Jones. I’m glad to know you’re doing ok. I still get compliments on your fajita recipe from people I’ve given it to.

  17. I am C Jones, formerly of Momfood. I tried blogging for a while and decided that it just wasn’t for me so I deleted the Momfood blog.
    Wow, I had no idea what has happened to it after that. I guess the lesson to be learned is not to delete a blog even if you no are no longer posting to it so that no one else can use that name for other purposes.

    Thanks for the kind words, Kalyn. I still read your blog regularly and have enjoyed watching your blog grow!

  18. Sarah, I have been wondering the same thing. I had to take off the link to MomFood because it was taken over by a creepy sex site. She seemed so nice, I really wonder what happened to her.

  19. I was just curious if you know what happened to the Momfood blog…I read this recipe, which sounds so yummy and easy, and searched for it (hoping to locate some more good crockpot recipes). I found cached pages from what I assume was the blog you were talking about but the momfood.blogspot.com is now a creepy site that has all these imbeded porn links. How bizarre.

  20. I ate this with chicken, peppers, and melted cheese layered with a dollop of sour cream (no tortilla) and it was delicious.
