Ingredients

Scale
  • 3 lbs boneless, skinless chicken breasts or thighs
  • 3 bell peppers (any color combination), sliced
  • 1 large onion, sliced
  • 3 cloves garlic, 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 salt
  • 1/4 teaspoon black pepper
  • 1/4 cup chicken broth or water

Instructions

  1. Place the chicken breasts or thighs into the bottom of your slow cooker.
  2. In a separate bowl, mix together the chili powder, cumin, paprika, onion powder, garlic powder, oregano, salt, and pepper to create the fajita seasoning blend.
  3. Sprinkle the seasoning mix evenly over the chicken.
  4. Add the sliced bell peppers, sliced onion, and minced garlic on top of the chicken.
  5. Drizzle the olive oil over the vegetables and pour the chicken broth or water around the edges of the slow cooker.
  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 place it on a cutting board. Use two forks to shred the chicken easily.
  8. Return the shredded chicken to the slow cooker and stir it well with the peppers and onions to coat everything in the juices.
  9. Serve the fajita filling warm with tortillas and your favorite toppings.

Notes

  • For the most tender slow cooker chicken, cook on the LOW setting.
  • If you prefer a thicker sauce, 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.
  • Serve with warm flour or corn tortillas, sour cream, shredded cheese, salsa, and lime wedges.
