This pie combines shredded leftover chicken with a rich, creamy sauce and vegetables encased in buttery shortcrust or puff pastry. Nigella’s version is a straightforward yet luxurious take on a classic British comfort food, perfect for weeknight dinners or cozy gatherings.
Preheat your oven to 200°C (400°F).
Melt the butter in a large saucepan over medium heat. Stir in the flour and cook for 1-2 minutes to create a roux. Gradually whisk in the chicken stock and milk, stirring constantly until the sauce is smooth and thickened.
Add the leeks and mushrooms (if using) to the sauce and cook for 5 minutes until softened. Stir in the shredded chicken and thyme. Season with salt and pepper. Let the filling cool slightly.
Pour the filling into a pie dish. Roll out the pastry (if needed) and lay it over the filling. Trim the edges and crimp to seal. Use a knife to make small slits in the pastry to allow steam to escape.
Brush the pastry with beaten egg to give it a golden, glossy finish.
Place the pie in the preheated oven and bake for 25-30 minutes, or until the pastry is golden brown and crisp.
Let the pie cool for a few minutes before serving. Slice and enjoy warm with your favorite sides.
