Ingredients

Scale
  • 2.5 lb boneless, skinless chicken breasts or thighs
  • 3 bell peppers (red, yellow, green), sliced
  • 1 large onion, sliced
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon cayenne pepper (optional)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 cup chicken broth or water
  • Tortillas, sour cream, cheese, salsa, lime wedges for serving

Instructions

  1. Place the sliced bell peppers and onion in the bottom of your slow cooker.
  2. Place the chicken breasts or thighs on top of the vegetables.
  3. In a small bowl, mix together the chili powder, cumin, paprika, onion powder, garlic powder, oregano, cayenne pepper (if using), salt, and black pepper.
  4. Sprinkle the spice mixture evenly over the chicken. Add the minced garlic and olive oil over the top.
  5. Pour the chicken broth or water around the edges of the slow cooker.
  6. Cover and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours, until the chicken is fully cooked and tender.
  7. Remove the chicken from the slow cooker and place it on a cutting board. Shred the chicken using two forks.
  8. Return the shredded chicken to the slow cooker and stir to combine with the peppers, onions, and cooking liquid. Let it heat through for 10 minutes.
  9. Serve the crockpot chicken fajitas immediately with warm tortillas and your favorite toppings.

Notes

  • For the best texture, shred the chicken right before serving.
  • If you prefer less liquid, drain some of the excess broth before mixing the shredded chicken back in.
  • This recipe is excellent for meal prep; store the filling separately from the tortillas for up to four days.
