Ingredients

Scale
  • 3 lb boneless, skinless chicken breasts or thighs
  • 3 bell peppers, sliced (mixed colors)
  • 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 salt
  • 1/4 teaspoon black pepper
  • 1/4 cup chicken broth or water
  • Tortillas and desired toppings for serving

Instructions

  1. Place the chicken breasts or thighs into the bottom of your slow cooker.
  2. Arrange the sliced bell peppers and onion over the chicken. Sprinkle the minced garlic over the vegetables.
  3. In a small bowl, combine the chili powder, cumin, paprika, onion powder, garlic powder, oregano, salt, and pepper. Mix these fajita spices well.
  4. Sprinkle the spice mixture evenly over the chicken and vegetables. Drizzle the olive oil over everything. Pour the chicken broth or water around the edges of the slow cooker.
  5. Cover the slow cooker and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours. This is a true hands-off dinner recipe.
  6. Remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken to the slow cooker and stir to combine it with the peppers, onions, and juices.
  7. Let the mixture heat through for about 10 minutes on the LOW setting.
  8. Serve your tender slow cooker chicken fajitas immediately with warm tortillas and your favorite toppings.

Notes

  • For the best flavor, let this cook on LOW for the full 8 hours. This ensures the most tender slow cooker chicken.
  • If you prefer a slightly thicker sauce, remove the lid for the last 30 minutes of cooking time.
  • This recipe works great for meal prep chicken fajitas; store leftovers in the refrigerator for up to four days.
  • If you are looking for healthy slow cooker Mexican food, serve these over lettuce or brown rice instead of tortillas.
