Chicken and Potato Casserole

Preheat an oven to 180 C / Gas 4. Line a 23x33cm or similar sized baking dish with foil.

Spread the potatoes and onion into the bottom of the lined baking dish.

Stir the flour, salt and pepper together in a shallow bowl. Roll the chicken breasts in the flour mixture and arrange on top of the potatoes and onion.

Stir the vegetable oil, mushroom soup and water together in a bowl; pour over the chicken. Sprinkle the Cajun seasoning over the entire dish. Cover the dish with foil.

Bake the chicken breasts until no longer pink in the centre and the juices run clear, about 2 hours. An instant-read thermometer inserted into the centre should read at least 74 degrees C.
