Begin by patting the chicken fillets dry with paper towels, ensuring they are free of moisture for better seasoning adherence. Generously coat the chicken with Cajun seasoning, along with your choice of paprika, garlic powder, onion powder, salt, and pepper.

Next, place the seasoned chicken fillets in the bottom of your crockpot, laying them flat for even cooking. Slice the bell peppers and onions, then scatter them on top of the chicken, adding layers of vibrant colors and sweet flavors. Finish by mincing the garlic and sprinkling it over the entire mixture.

Pour the chicken broth evenly over all the ingredients in the crockpot. Make sure to cover the chicken thoroughly.

Cover the crockpot with its lid and set it to cook on low for about 6 hours, or on high for 3 hours. Ensure the chicken reaches an internal temperature of 165°F.

Once cooked, carefully remove the chicken from the crockpot and serve whole over rice or pull apart for sandwiches. Drizzle cooking liquid over the dish.
