Step 1: Prepping the Ingredients

The first step to perfect slow cooker fajitas is prepping your ingredients:

Slice the bell peppers and onions thinly and set them aside.
If you’re using homemade fajita seasoning, mix all the spices together in a small bowl.

That’s it! Now, let’s start layering everything in the crockpot.

Step 2: Assembling in the Crockpot

Now, the easiest part—just layer everything in the slow cooker:

Place the chicken at the bottom of the crockpot.
Sprinkle the fajita seasoning evenly over the chicken for that signature Tex-Mex flavor.
Add the sliced bell peppers and onions on top of the chicken.
Pour the diced tomatoes with green chilies and chicken broth over the vegetables.
Drizzle olive oil and fresh lime juice over everything for an extra boost of flavor.

That’s it! No need to stir—just cover and let the crockpot work its magic.

Now that everything is prepped and assembled in the slow cooker, it’s time to let the magic happen. The beauty of this recipe is that the crockpot does all the work for you.

Cooking Time Options

Depending on your schedule, you can choose between two cooking methods:

Low and Slow (Recommended): Cook on low for 6–7 hours for the most tender, flavorful chicken.
Quick and Convenient: Cook on high for 3–4 hours if you’re short on time.

During this time, the chicken will absorb all the spices, lime juice, and tomatoes, creating a rich, savory sauce. The bell peppers and onions will become perfectly soft, but not mushy, keeping that classic fajita texture.

One important tip: resist the urge to open the lid too often! Every time you do, heat escapes, which can slow down the cooking process. Let the slow cooker do its job, and you’ll be rewarded with perfectly juicy, seasoned fajitas.

Step 4: Shredding the Chicken

Once the chicken is cooked, it’s time to shred it.

How to Shred Chicken Like a Pro

Remove the chicken from the slow cooker and place it on a cutting board or large plate.
Use two forks to shred the chicken into bite-sized pieces. It should be incredibly tender and fall apart easily.
Return the shredded chicken to the crockpot and stir it into the sauce and vegetables. This step ensures that every bite is coated in flavor.

If you prefer chunkier chicken pieces instead of shredded, you can simply slice or roughly chop the chicken before adding it back into the crockpot.

At this point, the aroma filling your kitchen is incredible. The juicy chicken, seasoned veggies, and rich broth have come together to create the ultimate Tex-Mex experience. Now, it’s time to serve!

Step 5: Serving Your Slow Cooker Chicken Fajitas

The best part about these fajitas? They’re completely customizable! Here’s how to assemble them for the perfect bite:

Warming the Tortillas

For soft, pliable tortillas, try one of these warming methods:

Skillet: Heat each tortilla for about 30 seconds on each side in a dry skillet over medium heat.
Oven: Wrap tortillas in foil and warm at 350°F (175°C) for 10 minutes.
Microwave: Wrap tortillas in a damp paper towel and microwave for 20–30 seconds.

Assembling Your Fajitas

Spoon the shredded chicken and vegetable mixture onto a warm tortilla.
Add your favorite toppings, such as shredded cheese, sour cream, guacamole, salsa, fresh cilantro, or a squeeze of lime juice.
Wrap it up and enjoy! Fold in the sides, roll it up, and take a big, satisfying bite.

If you’re serving a crowd, set up a fajita bar with all the toppings so everyone can build their perfect fajita.

Bonus Tips for the Best Crockpot Fajitas

✔ Use Chicken Thighs for Extra Juiciness: While chicken breasts work great, chicken thighs stay even more tender and flavorful.

✔ Don’t Skip the Lime Juice: It adds the perfect tangy balance to the spices and makes the flavors pop.

✔ Make It Spicier: If you love heat, add some sliced jalapeños or a pinch of cayenne pepper to the seasoning mix.

✔ Thicken the Sauce: If you want a thicker sauce, remove some of the liquid after cooking and mix it with a teaspoon of cornstarch before adding it back in.

✔ Serve with Low-Carb Options: Swap the tortillas for lettuce wraps or serve the fajita mixture over cauliflower rice for a low-carb meal.
