Sprinkle chicken thighs with salt and Cajun seasoning, mixing well to coat evenly.
Heat a pan over medium heat and cook the chicken for a few minutes on each side until lightly browned. Remove and set aside.
In the same pan, add chopped onion, garlic, celery, and pepper. Stir in Cajun spices, rice, stock, chicken, and sweetcorn.
Cover and let everything cook until the rice is tender and the chicken is fully cooked.
Sprinkle with chopped coriander and serve
