slow cooker Chicken Fajitas
Chicken Fajitas are hands down one of a reliable meals. Grilled fajita meat is amazing, but sometimes I’m all about the ease of a slow cooker!
On busy days when I’m running around and need dinner ready the moment we walk through the door, the slow cooker is a total lifesaver. So, I set out to reliable fajitas in the slow cooker. After testing and tweaking the seasoning, veggies, and chicken, I can confidently say these fajitas are a big win.
Pile them high with your favorite toppings, and you’ve got the easiest, most flavorful dinner waiting for you!

Ingredients
Here’s what you’ll need to make slow cooker Chicken Fajitas:
- Olive oil and onion: Cook onion in oil for a sweeter, better flavor. Raw onions stayed too firm and didn’t taste as good in testing.
- Chicken thighs: Trim large pieces of fat, but leave a little for extra flavor.
- Diced green chiles: Use mild for less spice; fire-roasted more flavor!
- Diced tomatoes: Fire-roasted gives a great smoky flavor. No need to drain!
- Bell peppers: Use red, yellow, and green for sweet, bright colors.
- Garlic: I use both minced garlic and garlic powder for even more flavor.
- Chili powder, cumin, and paprika: Adds warm and rich flavors.
- Onion powder: Makes the onion flavor pop.
- Salt and pepper: Pulls all the flavors together. Add more if needed.

To make a freezer meal, cook the onions and let them cool. Add everything to a freezer bag, press out the air, seal, and freeze. Thaw overnight in the fridge and cook in the slow cooker as directed.

To char tortillas, place them directly over a gas flame or in a dry skillet over a medium burner. Cook for 10-20 seconds per side until lightly charred and warmed. Flip with tongs and serve warm.
