A Note from Kim

Flavor-Packed & Hands-Off!

Crockpot Chicken Fajitas are a lifesaver on busy days, especially when it’s too hot to even think about turning on the oven. There’s no marinating or sautéing required, which makes them even more of a weeknight win. They’re easy, flavorful, and loaded with all your favorite toppings. I make them on repeat all summer long, and trust me, once you try them, you’ll see why!

With love (and lots of good eats), - Kim

Delish! Was a thumbs up for dinner tonight. The spice mix was a winner too!

Ingredients You’ll Need

All simple ingredients you can easily find at the grocery store without too much hassle! Be sure to use a flavorful salsa that you love because this is where much of the flavor in this recipe will come from! Here’s what you’ll need:

  • Fajita seasoning: This recipe keeps things simple with a mix of basic spices—think chili powder, cumin, garlic powder, and a little salt. I like to make my own fajita and taco seasoning instead of buying pre-made store-bought packets. Not only does it have the best flavor, but it also ensures that the spice blend is free of fillers, preservatives, added sugar or funky ingredients that are often found in the pre-made packets.
  • Chicken: I used boneless skinless chicken breasts to keep things on the lighter side, but you can use chicken thighs instead for a richer and juicier flavor.
  • Sliced onion: Any thinly sliced onion variety works great. Use as much or little as you prefer.
  • Bell peppers: Red and green bell peppers are the ones I chose to use, but feel free to use any combination of peppers you want. You could also add some poblano peppers into the mix for a different flavor.
  • Salsa: You can use any favorite salsa here. You could even try making your own homemade salsa! To change things up salsa verde (green sauce) is another great option.
  • Lime juice: Don’t forget to add in some freshly squeezed lime juice at the end or right before serving. It really amps up the flavor of these fajitas!
  • Tortillas and toppings: This is the fun part! Some great options are guacamole (or avocado slices), sour cream (or Greek yogurt), pico de Gallo and a sprinkle of fresh cilantro.

Easy Ways to Mix It Up

  • Make it spicy: Stir in sliced jalapeños or add a few dashes of hot sauce or cayenne pepper to the spice blend.
  • Add beans: Toss in a can of drained black beans or pinto beans during the last hour for added texture and protein.
  • Try different tortillas: Serve it in flour tortillas, corn tortillas, lettuce wraps, or over a bowl of rice or quinoa for a low-carb option.

Instructions 

  • In a small bowl, combine the salsa and all spices; set aside.
  • Place the chicken into the bottom of a 6-quart slow cooker. Spoon and spread the salsa/seasoning mix over the chicken. Add onion and peppers. Cover crockpot with a lid and cook 4-6 hours on low or 3-4 hours on high or until chicken is cooked through and tender. Note: chicken breasts will take longer than tenders. About an hour before everything is finished cooking, I like to give the chicken, onion and peppers a good stir, to allow the peppers and onion to be evenly cooked.
  • Remove the chicken from slow cooker and shred with two large forks. Transfer the shredded chicken back into the slow cooker. Add freshly squeezed lime juice, mix everything together and taste. Season with salt if necessary.
  • Spoon the chicken mixture into heated tortillas using a slotted spoon or tongs and allow any excess liquid to drip back into the slow cooker. Add desired toppings and enjoy!

Notes

*Nutritional information does not include tortilla or additional toppings.
  • Storage. Any leftovers can be stored in an airtight bag or container and kept in the refrigerator for up to about 5 days.
  • Freezing. Allow the chicken to cool completely before transferring it to a freezer safe bag or container. It will stay good in the freezer for up to 3 months. When you’re ready to enjoy, thaw in the refrigerator before reheating.
  • Reheating. To reheat the leftover chicken, you can place it in the slow cooker and place it on “warm” to warm it back up. Alternatively, you can simply reheat it in the microwave or on the stovetop.

Kim’s Top Tips

  • Cook time: If you’re using raw chicken tenders instead of breasts, they will cook a bit quicker, about 3 to 4 hours on low.
  • Spice level: If you’re sensitive to spice, be sure to choose a salsa that has mild heat.
  • Cut veggies evenly: Slice your peppers and onions into similar-sized strips so they cook evenly in the crockpot.
  • Prep ahead: You can slice the peppers and onions the night before and store them in the fridge, so all you have to do is dump and go in the morning!

Frequently asked questions

What’s the best way to shred chicken?

The easiest way to shred chicken is with a hand mixer, just place it right in the slow cooker and mix on low until shredded. It takes less than a minute and saves on dishes! You can also use a stand mixer with the paddle attachment or go the traditional route with two forks. Once shredded, stir the chicken back into the juices for maximum flavor.

What’s the best way to warm tortillas?

Warming your tortillas makes them more flexible, flavorful, and less likely to tear when filled. For quick warming, wrap a small stack in a damp paper towel and microwave for 15–30 seconds. You can also warm them directly over a gas flame for 10–15 seconds per side or in a dry skillet or griddle until lightly toasted and pliable.

Can I use frozen chicken?

Yes! Just make sure the pieces aren’t stuck together and increase the cook time slightly, about 6–7 hours on low or 4–5 hours on high. Always check that the chicken reaches 165°F internally.

Serving Options

Not only are these slow cooker chicken fajitas super tasty, but they’re really versatile too! If you want to try something different other than stuffing a tortilla with the chicken, try using it in other recipes, like Mexican casseroles, soups and enchiladas. Here are some other options:

  1. Tacos. Stuff all of your favorite taco ingredients into soft tortillas or crunchy taco shells for Taco Tuesday!
  2. Chicken burrito bowls. Add rice, black beans, corn, guacamole and any other favorites with the tasty chicken for incredible burrito bowls.
  3. Quesadillas. This chicken and a little cheese cooked until melty and warm in fluffy flour tortillas makes for an easy, yet flavorful meal.
  4. Nacos. Use leftover shredded chicken to spread over tortilla chips along with cheese and other toppings.
  5. Salad. For a lighter meal option, make a chicken taco salad with all your favorite fresh Mexican ingredients.
