Sometimes the simplest meals are the best- just good ingredients and simple flavours. Chicken casserole is one of those things- Strip it back to the basics and it still tastes so good!
I like to use chicken thigh fillets, as honestly I am just not a fan of digging the bones out while I’m eating it, and the thigh fillets already have the skin removed which keeps them nice and lean. Thigh fillets are also a great value way of buying good quality free-range chicken as they are much cheaper than breast, and actually often much tastier.
I have kept this simple and the only vegetables in this version are onion, carrots and potatoes, but you really can add what you wish- any leftover bits of veg can go in really! Celery, leeks, broccoli, cauliflower, peas, asparagus, sweet potato, butternut squash, parsnip, swede- add in any of these along with the potatoes and carrots!
