Ingredients
For the Filling
- 500g cooked chicken breast or thigh, shredded or diced
- 2 medium leeks, trimmed and sliced
- 40g unsalted butter
- 2 tbsp plain flour
- 300ml chicken stock
- 100ml double cream
- 1 tsp Dijon mustard
- 1 tsp fresh thyme leaves or ½ tsp dried thyme
- Salt and freshly ground black pepper, to taste
For the Pastry
- 1 sheet ready rolled puff pastry
- 1 egg, beaten (for glazing)
For the Pie Dish
- Butter for greasing
How to Make James Martin Chicken And Leek Pie
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the pie cooks evenly and the pastry colours nicely.
- Cook the leeks: Melt the butter in a large frying pan over medium heat. Add the sliced leeks and cook gently for about 5 minutes until soft but not coloured.
- Make the sauce: Stir in the flour and cook for 1 minute. Gradually pour in the chicken stock, stirring constantly until the mixture thickens and becomes smooth.
- Add the chicken: Stir in the cooked chicken, double cream, Dijon mustard, and thyme. Season with salt and pepper. Simmer gently for 3 to 4 minutes until the filling is creamy and well combined.
- Assemble the pie: Spoon the chicken and leek mixture into a lightly buttered pie dish and allow it to cool slightly.
- Add the pastry: Lay the puff pastry over the dish, trimming any excess. Press the edges to seal and cut a small slit in the centre to allow steam to escape.
- Glaze the pastry: Brush the top of the pastry with beaten egg for a golden finish.
- Bake the pie: Place the pie in the preheated oven and bake for 25 to 30 minutes until the pastry is puffed and golden brown.
- Rest before serving: Allow the pie to stand for about 5 minutes before serving so the filling settles slightly.

Tips for the Best Chicken and Leek Pie
How do I keep the pastry crisp?
Allow the filling to cool slightly before adding the pastry. Very hot filling can soften the pastry and prevent it from rising properly.
Can I use leftover roast chicken?
Yes, leftover roast chicken works perfectly in this recipe and adds extra flavour to the filling.
How do I thicken the filling properly?
Make sure the flour cooks briefly in the butter before adding stock. This prevents a raw flour taste and creates a smooth sauce.
Should I vent the pastry?
Cutting a small slit in the pastry allows steam to escape and helps keep the topping crisp.
Serving Suggestions
- Buttery mashed potatoes
- Steamed green beans
- Roasted carrots
- A simple green salad

FAQs
Can I use shortcrust pastry instead of puff pastry?
Yes, shortcrust pastry works well for a sturdier pie. It will give a firmer base and a more traditional pie texture.
Can I make chicken and leek pie in advance?
Yes, you can prepare the filling a day ahead and store it in the refrigerator. Assemble with pastry and bake when ready to serve.
What can I use instead of double cream?
You can substitute single cream or crème fraîche for a lighter version while still keeping the filling creamy.
Can I add other vegetables?
Yes, mushrooms, peas, or carrots can be added to the filling for extra flavour and texture.
