How to Make Mary Berry Chicken and Leek Pie
Follow these step-by-step instructions for a perfect result every time.
- Preheat your oven to 200°C (180°C fan / Gas Mark 6). Lightly grease a medium-sized ovenproof pie dish.
- Cook the chicken. Place the chicken pieces in a large saucepan, cover with cold water, and add a generous pinch of salt. Bring to a gentle simmer over medium heat and cook for 15 to 18 minutes until just cooked through. Drain and set aside to cool slightly before cutting into chunks if needed.
- Soften the leeks and onion. Melt the butter in a large frying pan over medium-low heat. Add the onion and leeks, cooking gently for 8 to 10 minutes, stirring often, until soft, sweet, and fragrant. Do not let them brown.
- Build the sauce. Sprinkle the flour over the softened leeks and stir well for about one minute to cook out the raw flour taste. Gradually pour in the chicken stock, a little at a time, stirring constantly to keep the sauce smooth and lump-free. Once all the stock is incorporated, add the double cream and mustard, then stir to combine.
- Bring it together. Add the cooked chicken to the pan and stir gently until everything is evenly coated in the creamy sauce. Fold in the parsley, then season well with salt and black pepper. Taste and adjust seasoning as needed. Remove from the heat and allow the filling to cool for 5 to 10 minutes.
- Assemble the pie. Spoon the cooled filling into your prepared pie dish and spread it out evenly. Unroll the puff pastry sheet and carefully drape it over the dish. Press the edges firmly against the rim to seal, then trim away any excess. Use a sharp knife to cut a small steam vent in the centre of the pastry. Brush the entire surface generously with beaten egg.
- Bake. Place in the preheated oven and bake for 25 to 30 minutes until the pastry is puffed, deeply golden, and crisp. Allow to rest for 5 minutes before serving.
Tips for the Best Chicken and Leek Pie
How do I stop the pastry from going soggy?
Allow your filling to cool slightly before topping with pastry. Hot filling creates steam that softens the pastry before it even reaches the oven. Cutting a steam vent in the lid also lets excess moisture escape during baking, keeping the top beautifully crisp.
Can I use leftover cooked chicken?
Absolutely. Leftover roast chicken works brilliantly here and actually adds deeper flavour to the filling. Simply shred or chop the cooked chicken and stir it straight into the sauce. This is a fantastic way to use up a Sunday roast.
What leeks work best?
Medium-sized leeks with a good portion of pale white and light green stem give the best balance of flavour and texture. Avoid using too much of the dark green top, as it can be tough and slightly bitter. Always rinse leeks thoroughly after slicing, as grit tends to hide between the layers.
Serving Suggestions
Mary Berry’s Chicken and Leek Pie is a satisfying meal on its own, but the right sides make it truly complete. Here are some classic pairings:
- Creamy mashed potatoes for an extra layer of comfort
- Buttered garden peas or steamed tenderstem broccoli for freshness and colour
- Roasted carrots and parsnips for a hearty, warming plate
- Crusty white bread to mop up every last bit of the creamy filling
- A simple green salad if you want something lighter alongside
Storage
Room Temperature
Once baked, the pie should not be left out at room temperature for more than two hours. Cover loosely with foil if you plan to serve it within that window.
Refrigerator
Allow the pie to cool completely, then cover tightly with cling film or transfer to an airtight container. It will keep well in the fridge for up to three days. To reheat, place in an oven preheated to 180°C (160°C fan) and warm for 15 to 20 minutes until piping hot throughout. Avoid microwaving if you want to preserve the crispness of the pastry.
Freezing
This pie freezes well either before or after baking. If freezing unbaked, assemble the pie fully, wrap tightly in cling film and foil, and freeze for up to three months. Bake from frozen at 200°C (180°C fan) for 45 to 55 minutes. If freezing a baked pie, wrap individual portions and freeze for up to two months. Reheat from frozen in the oven at 180°C until heated through.

FAQ’s
Can I make the filling ahead of time?
Yes. The filling can be made up to two days in advance and kept covered in the fridge. Simply top with pastry and bake when you are ready.
Can I use shortcrust pastry instead of puff pastry?
Shortcrust pastry works well and gives a sturdier, more traditional pie crust. It will not puff up, but it delivers a satisfying, crumbly bite.
What can I add to the filling for extra flavour?
Mushrooms, smoked bacon lardons, fresh tarragon, or a splash of dry white wine are all excellent additions that complement the chicken and leek combination beautifully.
How do I know when the pie is cooked?
The pastry should be deep golden and fully puffed. Insert a skewer through the steam vent and hold it against your wrist; if it feels hot, the filling is heated through.
Can I make this pie gluten-free?
Yes. Use a gluten-free plain flour for the sauce and choose a gluten-free puff pastry sheet. Many supermarkets now stock a good gluten-free pastry option.
Is this the same as Mary Berry’s chicken pie with a potato topping?
No. That is a separate recipe that uses creamy mashed potatoes instead of puff pastry as the topping, similar in style to a shepherd’s pie but with a white sauce filling.

Mary Berry’s Chicken and Leek Pie is one of those recipes that earns a permanent place in your cooking rotation.
