Ingredients

  • 16 ounce jar salsa (divided use, I like Herdez brand salsa)
  • 1 red bell pepper (seeded & sliced into strips, divided use)
  • 1 yellow bell pepper (seeded & sliced into strips, divided use)
  • 1 green bell pepper (seeded & sliced into strips, divided use)
  • 1 yellow onion, sliced (divided use)
  • 4 cloves garlic, minced
  • 2 pounds boneless, skinless chicken breasts

  • Onion: Yellow, white, or red onion all work beautifully in this fajita recipe. Choose your favorite!
  • Garlic: Freshly minced garlic provides the best aroma and taste. Jarred minced garlic is a convenient alternative if needed.

  • Chicken: For an even juicier result, swap boneless, skinless chicken breasts for chicken thighs.
  • Seasoning: A store-bought fajita seasoning packet is super convenient, but you can also mix your own.
  • Lime Juice: Fresh lime juice brightens all the flavors and is an essential finishing touch. Do not skip it.
  • Frozen Ingredients: You can use frozen pre-sliced peppers or even frozen chicken breasts directly in the crockpot. Adjust cooking time slightly.

Equipment

You only need a few basic kitchen tools to make these fantastic crockpot chicken fajitas.

  • 6-quart crockpot (slow cooker)

Instructions To Make Crockpot Chicken Fajitas

Creating delicious crockpot chicken fajitas is incredibly straightforward. Just follow these simple steps for a perfect meal.

  1. Layer First Half: Begin by pouring half of your 16-ounce jar of salsa into the bottom of a 6-quart crockpot. This creates a flavorful base for your ingredients.
  2. Add Vegetables: Next, evenly layer half of the sliced red, yellow, and green bell peppers over the salsa. Follow with half of the sliced yellow onion.
  3. Garlic Layer: Sprinkle the 4 cloves of minced garlic directly over the layer of vegetables. This ensures the garlic flavor distributes well.
  4. Add Chicken: Carefully place the 2 pounds of boneless, skinless chicken breasts on top of the vegetables. Arrange them in a single layer if possible for even cooking.
  5. Season Chicken: Generously sprinkle the entire packet of fajita seasoning over the chicken breasts. This infuses the chicken with classic fajita flavors.
  6. Layer Second Half: Now, add the remaining salsa, peppers, and onions over the chicken. This creates layers of flavor that will meld during cooking.
  7. Add Lime Juice: Squeeze the 2 Tablespoons of fresh lime juice over the top of all the ingredients. The lime juice adds a bright, zesty finish.
  8. Cook Thoroughly: Cover your crockpot with the lid. Cook the mixture on the LOW setting for 6-8 hours, or on the HIGH setting for 3-4 hours. Ensure the chicken reaches an internal temperature of 165°F to be safely cooked through.
  9. Shred Chicken: Once cooked, carefully remove the chicken breasts from the crockpot and place them on a cutting board or shallow dish. Using two forks, shred the chicken into bite-sized pieces. It should shred easily.
  10. Combine & Serve: Return the shredded chicken to the crockpot. Stir everything together gently, allowing the chicken to mix with the flavorful vegetables and sauce. Switch your crockpot to the “warm setting” if you are not serving immediately.
  11. Adjust & Enjoy: Before serving, give the crockpot chicken fajitas a taste test. You may wish to season with a pinch of salt and black pepper if desired. Serve the warm fajita mixture with your favorite tortillas and an array of toppings.

Pro Tips & Troubleshooting

Making delicious crockpot chicken fajitas is simple, but a few tricks can make them even better.

  • Don’t Overcrowd: Ensure your crockpot isn’t overly full. Leave some space for even cooking and proper heat circulation.
  • Internal Temperature: Always use a meat thermometer to check the chicken. According to the USDA, all poultry should reach a safe minimum internal temperature of 165°F (73.9°C) to ensure it is safely cooked.
  • Don’t Overcook: While slow cookers are forgiving, chicken can dry out if cooked for too long. Stick to the recommended times.
  • Drain Liquid: If your fajitas have too much liquid after cooking, you can carefully ladle some out before serving.
  • Sear Chicken (Optional): For deeper flavor, briefly sear the chicken breasts in a hot pan before adding them to the crockpot. This creates a nice crust.
  • Homemade Seasoning: Mix your own fajita seasoning blend using chili powder, cumin, paprika, onion powder, garlic powder, and a pinch of cayenne.
  • Spice It Up: Add a diced jalapeño or a dash of cayenne pepper to the crockpot along with the other ingredients for extra heat.
  • Keep Warm: The “warm” setting on your slow cooker is perfect for keeping your fajitas hot for up to an hour if serving later.

Serving, Storage & Variations

These slow cooker chicken fajitas are incredibly versatile. You can easily adapt them to fit your preferences or dietary needs.

Serving Suggestions:

  • Tortillas: Serve the warm fajita mixture in soft flour or corn tortillas.
  • Toppings: Offer a selection of shredded cheese, cool sour cream, creamy guacamole, fresh pico de gallo, and crisp lettuce.
  • Sides: Pair your fajitas with classic Spanish rice, flavorful Mexican rice, simple black beans, or a refreshing side salad.

Storage:

  • Refrigerate: Store any leftover fajita mixture in an airtight container in the refrigerator for up to 2-3 days.
  • Freeze: For longer storage, cool the mixture completely, then transfer it to a freezer-safe bag or container. It will keep well for up to 2 months. Thaw overnight in the refrigerator before reheating.

Variations:

  • Beef Fajitas: Substitute the chicken breasts with 2 pounds of thinly sliced chuck roast or flank steak for a different protein option.
  • Vegetarian Fajitas: Create a meatless version by using thick-sliced portobello mushrooms, extra bell peppers, or a plant-based protein.
  • Low-Carb Fajitas: Skip the tortillas and serve your fajita mixture over crisp lettuce cups or with cauliflower rice.
  • Spicy Fajitas: Boost the heat by adding a diced jalapeño, a serrano pepper, or a generous pinch of cayenne pepper during cooking.
