Slow Cooker Chicken Fajita Tacos

If you’ve had fajitas in a Mexican restaurant, you know that they should come to your table sizzling on a cast iron skillet. If they don’t, your mom might send them back. Wait, that’s my mom. Love you, mom.

Anyways, while these Slow Cooker Fajitas don’t arrive sizzling on a skillet, they do have all the tantalizing Tex-Mex flavors you’re looking for in a fun Taco Tuesday!

How to make Slow Cooker Chicken Fajitas:

Now there are two ways to make these fajitas:

For the first way, you can go the dump-and-go route, which is to just add all the ingredients at the same time. A couple hours later, everything is done and you make your tacos.
Alternatively, for those that prefer more texture to their veggies, add the chicken and spices in the beginning, and at the half-way point, add the veggies. Whatever works for you.

📍The full recipe with exact ingredient amounts and instructions is on the recipe card at the bottom of the post.

What toppings are good for Chicken Fajita Tacos?

Feel free to replace tortillas with Mexican Rice and make burrito bowls!

Corn or flour tortillas
Sour cream
Salsa (store-bought or homemade)
Avocado or guacamole
Chopped cilantro
Pickled jalapenos
Hot Sauce (homemade store-bought)
Shredded cheese

Sometimes I get burrito-size flour tortillas and make burritos instead.
