Jamie Oliver leftover turkey pie is a British-style savoury pie made by combining cooked turkey with vegetables and a creamy sauce, then baking it under puff or shortcrust pastry. It’s designed to be warming, economical, and full of flavour while keeping preparation straightforward.
Heat the olive oil or butter in a wide pan over medium heat. Add the onion, carrot, and leek or celery, cooking gently for 8–10 minutes until softened. This slow cooking builds sweetness and forms the base of the pie filling.
Stir in the garlic and cook briefly until fragrant. Sprinkle in the flour and stir well, allowing it to cook for a minute so the sauce thickens smoothly without tasting raw.
Gradually pour in the stock, stirring constantly to avoid lumps. Add the cream or milk, Dijon mustard, herbs, salt, and black pepper. Simmer gently until the sauce thickens and coats the spoon.
Add the cooked turkey to the sauce and stir carefully to coat without breaking it up too much. Taste and adjust seasoning if needed, then remove from heat.
Preheat the oven to 190°C (375°F). Spoon the turkey filling into a pie dish and allow it to cool slightly. Lay the puff pastry over the top, trim the edges, and crimp gently.
Brush the pastry with beaten egg and cut a small slit in the centre to allow steam to escape during baking.
Bake for 30–35 minutes until the pastry is puffed, crisp, and deep golden, and the filling is bubbling underneath.
Let the pie stand for 5 minutes before serving to help the filling settle and slice neatly.
