Years ago I got this recipe for Chicken Fajitas in the CrockPot 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 Crockpot 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!

Chicken Fajitas in the Crockpot

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

Chicken Fajitas in the Crockpot 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.

  1. The chicken and vegetables give off so much liquid during cooking that you really don’t have to add any extra liquid to the crockpot when cooking. I’ve stopped adding extra liquid because it was coming out too soupy. This is super good, and I’ve made it at least 5 times since I found the recipe. Keep up the great work. You’re recipes are usually a hit.

    • Glad to hear you are having good luck with that. Some slow cookers are hotter or cooler than others, so I think that affects how much liquid is released. But I think I’ll try it without adding liquid.

      And so glad you are enjoying the recipes, thanks!

  2. I’m definitely gonna try this. Having a slow cooker makes life so much easier for busy moms like me.

  4. Molly I would not really recommend freezing this because the vegetables are already pretty soft from the slow cooker and I think freezing would turn them to mush. Sorry.

  5. I did not notice the "can freeze" tag for this recipe and wanted to know your thoughts. I would like to make a big batch of the fajitas and freeze for quick lunches (fajita bowl style without a tortilla).

  6. I've never tried it with frozen chicken breasts, but I wouldn't recommend it because I think the vegetables would get overcooked by the time the chicken was thawed and done.

  7. Can u use frozen chicken breasts

  8. Sarah, so glad you liked it. Good idea to increase the vegetables.

  9. Made this and hubbs and I LOVED it! Making again this week and will double the veggies as we are veggie lovers. Thanks so much!

  10. So glad you enjoyed it!

  11. I just found this recipe this past Sat. and fixed it on Sunday. It was so good. The chicken was so soft and tender. Thanks for the recipe.
