Ingredients

Scale
  • 3 lb boneless, skinless chicken breasts or thighs
  • 3 bell peppers, sliced (use varied colors for best look)
  • 1 large onion, sliced
  • 3 garlic cloves, minced
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon paprika
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon cayenne pepper (optional, for heat)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 cup chicken broth or water

Instructions

  1. Place the chicken breasts or thighs into the bottom of your slow cooker.
  2. In a small bowl, mix together the chili powder, cumin, paprika, onion powder, garlic powder, oregano, cayenne pepper (if using), salt, and black pepper to create your fajita seasoning mix.
  3. Sprinkle the seasoning mix evenly over the chicken.
  4. Add the sliced bell peppers and onion over the chicken. Add the minced garlic.
  5. Pour the olive oil and chicken broth over the ingredients.
  6. Cover the slow cooker 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 shred it using two forks. Return the shredded chicken to the slow cooker and stir it into the peppers and onions to coat with the juices.
  8. Serve the tender shredded chicken fajitas warm with tortillas and your favorite toppings.

Notes

  • For the best texture, shred the chicken right in the slow cooker juices. This keeps the meat moist.
  • If you prefer less liquid in your final fajita filling, remove the lid for the last 30 minutes of cooking time on HIGH.
  • This recipe is great for meal prep; store the filling separately from the tortillas.
