Slow Cooker Chicken Fajitas

Fajitas Made Easier

I’m a huge fan of slow cookers and as we are heading at what seems like warp speed into the school year and the weather cooling down I am using my slow cooker so often I’ve stopped putting it away between uses!

Slow Cooker Chicken Fajitas have been around for a heck of a long time. They’ve been on Pinterest for years before I even started this blog, but I mostly saw slow cooker fajitas using fajita seasoning mixes, rather than a homemade seasoning blend.

VERSATILE Chicken Fajitas BAse

To make these crockpot chicken fajitas, I used exactly what I would use to make my fajitas at home. Personally, I don’t use a mix, but you can choose to if you like. I like to add in some salsa to round out the flavors and make it a base recipe you could use in other applications as well. Below are some of the recipes you can make with this chicken fajitas base:

  • Enchiladas: Shred everything to make a base mixture for enchiladas made with my enchilada sauce
  • Taquitos: Roll this chicken fajitas mixture into flour or corn tortillas and fry into taquitos (make sure to use the least amount of liquid possible).
  • Soup: Add chicken broth, beans, and corn to make a soup with some crunchy tortilla strips on top.
  • Fajitas Bowl: chop up the chicken and add it to the top of a Chicken Fajita bowlfajitas made in slow cooker

Tips for Crockpot Chicken Fajitas

  • If you want your chicken to shred, feel free to let the chicken cook for longer than directed in the recipe. I listed it as 3 hours on high or 6 hours on low to allow you to cut your chicken into slices.
  • You can also easily freeze this chicken fajitas recipe for future cooking, I usually make a double batch, freeze a bag of ingredients and cook one off.

Tools USED to Make Chicken Fajitas

  1. Slow Cooker: Love this slow cooker and how programmable it is, it has been a workhorse for me… until…
  2. My New Slow Cooker: This recipe was made in this slow cooker. For larger roasts, I also brown the meat in the insert and not lose a bunch of the flavor by transferring the meat and leaving the browned bits behind. If you’re thinking of a new slow cooker, consider it if your budget is open.
  3. Salsa: I love making salsa at home, check out my favorite Guapo’s Mexican Salsa, but for a quick swap I LOVE this one from Costco (link for reference).
  4. Fajita Seasoning Mix: If you are skipping the spices and going for a mix this is the brand I love and have in my pantry as a backup.
  5. Freezer Bags: Other brands may be more popular, but I have never had a bag burst/leak with this brand. I have however with Ziploc.

Slow Cooker Chicken Fajitas are made with homemade fajita seasoning mix, chicken, onions and bell peppers for the perfect easy weeknight meal.


  • 1 tablespoon cornstarch
  • 2 teaspoons chili powder
  • 1 teaspoon salt
  • 1 teaspoon paprika
  • 1 teaspoon white sugar
  • 1 teaspoon dried onion flakes (you can substitute onion powder)
  • 1/4 teaspoon cayenne pepper (I use 1/2 teaspoon because we like a bit more spice)
  • 1 teaspoon ground cumin
  • 4 boneless skinless chicken breasts
  • 1 yellow onion , cut into 1/2 inch wedges
  • 1 red bell pepper , sliced
  • 1 green bell pepper , sliced
  • 4 cloves garlic , minced
  • 1 cup salsa
  • 1 lime , cut into wedges
  • chopped cilantro , as a garnish


Note: click on times in the instructions to start a kitchen timer while cooking.

  1. Mix the cornstarch, chili powder, salt, paprika, white sugar, dried onion flakes, cayenne pepper and ground cumin in a small bowl.
  2. Add the chicken, onions, garlic, bell peppers and salsa to your slow cooker.
  3. Add the seasonings over the top of the mixture.
  4. Cook on high for 3 hours or on low for 6 hours. If you cook longer it will also taste fine, but cutting may be more difficult because the chicken will break down easier.

  5. Squeeze fresh lime juice over the top of your chicken (do not add before, it won't have the same flavor after cooking for so long).
  6. Garnish with cilantro (optional).

Recipe Notes

You can substitute Fajita Seasoning Mix for the ingredients listed from the cornstarch through the cumin. I would still highly suggest adding the fresh garlic though.

  1. I can’t wait until I can try this recipe. I LOVE fajitas, just something about the mix of chicken, peppers, onion & spices. I’ve looked for a LONG time for a slow cooker recipe that resembles the “kit” I bought years ago….
    Now, my question: You said it can be frozen… so do you just wait & mix together the cornstarch & spices until you are ready to cook the frozen one? And…do you need to take the frozen one out, thaw it to cook it or just dump it in frozen..(I know it would take longer to cook). Just wondering. THIS recipe really has me excited! Thank you! 🙂

    1. I’m so glad you’re excited! I usually take the frozen bag (chicken, onions, garlic, bell peppers) and place it in the refrigerator overnight before tossing it into the slow cooker with the other ingredients the next day. Enjoy!

  2. This turned out amazing and was so easy! I had to have something for Easter that I could throw in the crockpot about 6:45 and would be ready about 11 and this meal was perfect. Everyone loved it and the taste was delish and super easy

  3. O – M – G!! Hands down the best fajitas we have ever had!! The flavor was to die for! It was spicey and so good! Every time I post a meal and swear it was our favorite one, you outdo yourself again! You can cook, woman! Thanks so much for sharing this amazing recipe!! ~Cindy

  4. I have to tell you that your blog is probably one of my most favorite! You always have great recipes and/or tips and you always provide the links I need to get to an older blog post or another idea. KEEP UP THE GREAT WORK!! 🙂 😉
