How to Make Mary Berry Chicken and Leek Casserole

- Add the onion and garlic to the pan and cook gently until softened. Add the butter, then sprinkle in the flour and stir well to create a smooth base.
- Slowly add the hot chicken stock and apple juice, stirring continuously until the sauce is smooth. Add the crème fraîche, mustard, thyme, and seasoning, then stir until thickened.
- Add the leeks and potatoes to the sauce and mix everything together. Place the chicken on top, cover with a lid or foil, and ensure the edges are sealed well.
- Transfer the dish to the oven and bake until the chicken is fully cooked through. The casserole should have a creamy sauce and tender texture when ready.
- Before serving, remove the cover and sprinkle with fresh parsley. Serve the casserole with a green vegetable for a complete meal.
