The extras that you put in the tortillas is up to you. In fact, you don’t need to add any kind of extra but instead just have the chicken filling. Personally, I love having it with some baby spinach, sour cream, and shredded cheese. There are a ton of combinations that you’re able to do! If you have a certain combination that you would love to share then don’t hesitate to leave a comment below.

One thing that you need to be aware of is that this dish will produce a fair bit of liquid. When you serve the fajita chicken filling make sure you drain some of the excess liquid, otherwise your tortilla might become a bit soggy.

Cooking fajitas in the slow cooker is far from the traditional style of cooking this dish. Usually, you will fry or grill the meat along with some vegetables. Instead we will be slow cooking the ingredients for a long time, but the result is still an incredible flavor-packed chicken and veg mix.

Chicken Fajitas

You can use the slow cooker chicken fajita mix in a range of different dishes and not just as a filling with tortillas. For example, this mix will go great as a topping on nachos or even as a topping on pizza.

This dish is packed full of flavor and is fantastic when you need to feed a crowd. You can easily bulk this out as much as you want. Just make sure your slow cooker is big enough to fit all the ingredients.

Recipe Tips

  • You can easily swap the chicken thigh out for breast. Both types of meat will work just fine.
  • Much like taco seasoning, you can also make a fajita mix right at home.
  • You don’t have to use fresh lime juice, if you’re using it out of a bottle you will need about 2 Tbsp. of juice.
  • You can use any type of salsa in this recipe. Personally, I prefer a spicier salsa but keep in mind that the fajita spice mix will also add a bit of heat to the dish.
