What You’ll Need

  • Chicken – We used boneless, skinless breasts.
  • Salt
  • Fajita Seasoning
  • Onion
  • Bell Peppers – We used a mix of green, red, and yellow varieties.
  • Pineapple
  • Chipotle Peppers in Adobo Sauce
  • Canned Diced Tomatoes

DIY Chicken Fajita Seasoning

If you prefer, you can skip the premade chicken fajita seasoning, and make your own with spices you already have around the house! Just combine chili powder, cumin, paprika, garlic powder, onion powder, cayenne pepper, salt, and any other flavors you’d like to add such as oregano or sugar! Here’s an easy recipe if you need help getting started.

How to Make Crock Pot Chicken Fajitas

Hold onto your apron, because you won’t believe how ridiculously easy this recipe is! Seriously, it’s like magic in the kitchen with just a few minutes of prep.

  1. Start by preparing your veggies, and slicing them into thin strips.
  2. Then, trim any excess fat or bad pieces off your chicken breasts.
  3. Add the chicken to the slow cooker in an even layer, and sprinkle the seasoning on top. Make sure each breast is well-coated!
  4. Next, add the veggies, pineapple chunks, chipotle peppers, and tomatoes.
  5. Cover the crock pot, and let it cook on high for 2 hours or low for 4 hours.
  6. Remove the chicken, slice it into pieces, and return it to the crock pot. Mix all of the ingredients evenly, and enjoy!

Serving Suggestions

One of the best things about crock pot chicken fajitas is how versatile it can be! We went the white rice route, but honestly, this dish is like the culinary equivalent of the wardrobe staple that goes with everything. Wrap it up in tortillas, toss it on greens for a salad upgrade, spoon it over tortilla chips for the best nachos ever, or mix them into your morning eggs for an omelet upgrade! And don’t forget to sprinkle on some beans, add a dollop of sour cream, and pile on a generous heap of shredded cheese for that extra pizzazz.

Storage and Meal Prep

We like to make a big batch of crock pot chicken fajitas to eat throughout the week. Luckily, they store super well. Just be sure to place them in an airtight container, and keep them in the fridge for up to 3-4 days.

Or, place leftovers in the freezer for up to 9 months. Then, when you’re ready to eat, thaw them in the fridge overnight.

How to Reheat

When you’re ready to eat, add your fajita mixture to a baking dish, cover it with foil, and let it heat in the oven for about 30 minutes at 365° Fahrenheit. Or, add it to a skillet over medium heat until heated through. If you must, you can warm them in the microwave as well, but this method may result in dry chicken.

Is it Better to Cook on Low or High Heat?

For the best results, we recommend cooking your chicken on a low heat setting. This helps keep it extra moist and juicy.

However, the high setting works, too if you’re in a bit of a pinch for time! Just be sure not to forget about it as leaving it in the crock pot for longer than 2 hours will likely cause it to become a bit dry.

Do I Have to Use Chicken?

Not at all! We prefer chicken because it’s super easy, affordable, and usually satisfies everyone. However, this recipe should work with any meat you’d like to substitute such as steak or shrimp. Just note that the cooking times will likely vary.

Can I Use Frozen Vegetables?

Yes! If you want to save time, you can usually even find pre-sliced onions and peppers in the frozen section of your local grocery store. Just keep in mind that your fajita mixture may be slightly more watery than if you used fresh vegetables.
