How To Make Slow Cooker Chicken Fajitas

Chicken fajitas don’t take too long to make in a pan, but sometimes, like other slow cooker recipes, it’s nice to come home to a meal ready to serve. 

slow cooker chicken fajita ingredients

What You Need:

  • Chicken
  • Fajita mix
  • Tinned tomatoes
  • Mixed peppers 
  • Onion

The Chicken

I used chicken breasts for this meal, but you can also use boneless chicken thighs.  

Fajita Seasoning

Much like fajitas made in a pan, you can either use a homemade fajita seasoning mix, or grab a premade one from the supermarket.

To make your own, use a combination of spices including; chilli powder, smoked paprika, garlic powder, ground coriander, ground cumin.

Making It

It really is a case of adding everything to the slow cooker, mixing it together, adding the lid and turning the slow cooker on.

If you are using chicken breasts, cook on low for 4 hours, or high for 2 to 3 hours. Chicken thighs can be cooked for longer as they won’t dry out so quickly.

At the end of the cooking time remove the chicken from the slow cooker and slice it up, or shred it.

If the remaining sauce seems too thin you can leave it to cook on high for a further 20 to 30 minutes with the lid off, or transfer it to a saucepan and simmer it to reduce the consistency.

How To Serve Chicken Fajitas

Slow cooker chicken fajitas can be served with rice, in tortilla wraps (with salsa, lettuce and grated cheese), over nachos, or on top of a jacket potato.
