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. The result is still an incredible flavor-packed chicken and vegetable mixture.

This dish is packed full of flavor and is fantastic for when you need to feed a crowd. Without any adjustments, this dish should feed six people. You can easily bulk out the chicken mixture as much as you want. Just make sure your slow cooker is big enough to fit all the ingredients.

You can also use this slow-cooked chicken fajita mix in different dishes. For example, this mix will go great as a topping on nachos or even as a topping on pizza.

Assembling your Fajitas

The extras that you put in the tortillas is up to you. You do not need to add any additional ingredients and instead have just the fajita chicken mixture.

Personally, I love having my fajitas with some baby spinach, sour cream, and shredded cheese. It is an incredibly tasty filling that I highly recommend that you try.

Perfecting the Recipe

One thing that you need to be aware of is 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.

You can use any type of salsa in this recipe. I prefer a spicier salsa, but keep in mind that the fajita spice mix will add a bit of heat to the dish.

You can easily swap the chicken thigh for chicken breast. Both types of meat will work perfectly in this dish. I always tend to lean towards using chicken thigh as it is unlikely to overcook easily.

Recipe Tips

  • Much like taco seasoning, you can also make a fajita mix right at home.
  • You do not have to use fresh lime juice. If you are using juice from out of a bottle, you will need about two tablespoons.
  • If you are running low on time, you can switch the slow cooker to high and halve the cooking time.

Note: I use a 5.5L (6 Quart) slow cooker (Amazon | Walmart) for all the recipes that I have on this website unless specified. If you have a smaller or larger slow cooker, then you might need to adjust the ingredients.
