Ingredients for the Chicken Casserole
The recipe calls for a selection of fresh and accessible ingredients, making it an ideal choice for home cooks. You will need:
- 350g baby new potatoes
- Salt and freshly ground black pepper
- Four thin leeks, cut into 2cm slices
- Six small chicken breasts, skinless and boneless
- One tbsp olive oil
- One tbsp runny honey
- 50g butter
- One onion, thinly sliced
- One garlic clove, crushed
- 50g flour
- 450ml apple juice
- 200ml full-fat crème fraiche
- One tbsp chopped fresh thyme leaves
- Two tbsp chopped fresh parsley
Step-by-Step Method
To prepare this delicious casserole, you will require a 2.3 litre ovenproof dish. Begin by buttering the dish to prevent sticking. Place the baby new potatoes in a saucepan, cover them with cold water, add a pinch of salt, and bring to the boil. Cook at boiling point for 12 minutes, then add the leeks and boil for an additional three minutes, or until the potatoes are tender. Drain the vegetables in a colander and set aside.
Season the chicken breasts with salt and pepper. Heat a little olive oil in a large frying pan, add the chicken, and drizzle with honey. Brown the chicken for several minutes until golden, then remove from the pan and set aside. Do not clean the frying pan; instead, add the butter, onion, and garlic. Cook for a minute, cover with a lid, and leave to simmer for 10 minutes.
Remove the lid and turn up the heat slightly. Stir in the flour and apple juice until the mixture is smooth, then mix in the crème fraîche and thyme. Season with additional salt and pepper. Continue stirring as the mixture thickens and bring it to the boil. Remove the pan from the heat and add the leeks and potatoes, mixing everything thoroughly.
Transfer the contents of the pan to the prepared ovenproof dish. Arrange the chicken pieces on top, cover with foil, and seal the edges. Place in a preheated oven at 200C (180C fan/Gas 6) for 25 minutes. Remove the foil and cook for another 10 minutes. Finally, sprinkle with freshly chopped parsley and serve with a portion of green vegetables for a complete and satisfying meal.
