Fajitas! It’s a fun word to say and an easy dinner to whip up. However, if you want to make your fajitas a completely hands-off recipe, there’s no better way than in the crockpot. With these crockpot chicken fajitas, you don’t have to stand at the stovetop making your dinner. The slow cooker does all the work for you!

Of course, that’s not the only reason we love using the slow cooker. It also makes the chicken tender and juicy, with vegetables that are cooked to perfection. If you enjoyed my Slow Cooker Salsa Chicken and 4-Ingredient Crock Pot Chicken Tacos, you’re going to love crockpot chicken fajitas too!

Easy Slow Cooker Chicken Fajitas

This easy chicken dinner requires only a handful of everyday ingredients. Then, you can go to town with your choice of toppings. (In my family, sour cream and cheese are always a must.)

To make your crock pot chicken fajitas, simply add everything to the crockpot, set it, and forget it until dinner time. You have the option of cooking on high for 3 or 4 hours, or on low for 6 to 7 hours. So, choose whichever works best for your schedule.

Oh, and I can’t forget to mention that these crockpot chicken fajitas are healthy, too. You can skip the tortillas, and use lettuce cups for a low-carb, keto-friendly dinner. Or, serve the chicken and veggies over Instant Pot rice or cauliflower rice to keep it low-cal. It’s a great meal prep option for healthy weekday lunches!

ingredients to make crockpot chicken fajitas.


See recipe card below this post for ingredient quantities and full instructions.

  • Boneless, skinless chicken breasts – You can also use thighs if that’s what you prefer.
  • Yellow onion
  • Red bell pepper – Yellow or orange work too.
  • Green bell pepper
  • Garlic
  • Medium or hot salsa – Consider this our secret ingredient! Using jarred salsa means you don’t have to make your own sauce with tomatoes.

  • Kosher salt
  • Black pepper You can also add cayenne pepper if you want to make this chicken fajita recipe spicy.
  • Nonstick cooking spray
  • Flour tortillas – You can use corn tortillas if you prefer, but flour tortillas are the most common choice for chicken fajitas.

Topping Ideas

  • Shredded Mexican-style cheese
  • Sour cream
  • Guacamole
  • Pico de gallo

  • Fresh cilantro

How to Make Crockpot Chicken Fajitas

  1. Prepare: Coat the inside of a large crockpot with nonstick cooking spray.
  2. Season the vegetables: In a large bowl, toss the onion, peppers, garlic, salsa, and spices until the veggies are evenly coated. Spread half of the veggies onto the bottom of the slow cooker.
  3. Finish assembling: Lay the chicken breasts over the top of the veggies, followed by the remaining salsa mixture.
  4. Cook: Cook for 3 to 4 hours on high or 6 to 7 hours on low until the chicken is completely cooked through. 
  5. Shred the chicken: Remove the chicken from the slow cooker with a slotted spoon, and let it cool for 5 minutes. Use a fork to shred it into bite-sized pieces. Then, return the chicken to the slow cooker. 
  6. Serve: Stir the chicken back into the fajita mixture, and serve on flour tortillas with your desired toppings.

Quick Tip

It’s always best to use a probe thermometer to determine when the chicken is done. It should reach an internal temperature of 165ºF.

Store leftover crockpot chicken fajitas in the refrigerator for up to 4 days. Or, freeze them for up to 3 months. Thaw in the fridge overnight before serving

Reheat the fajitas in a skillet over medium heat until warmed through. Or, microwave in 30-second intervals.

More Serving Suggestions

You don’t have to use this crockpot chicken fajitas recipe for fajitas! You can pile it onto buns with avocado slices and make Tex-Mex sandwiches.

Or, serve it over Mexican rice and black beans, or use it as a burrito filling (or in a burrito bowl!). You can even make it into cheesy sheet pan quesadillas, maybe with some refried beans on the side!

If your family hates having the same meal two nights in a row, you can easily reinvent the leftovers and make something brand new!
