This creamy chicken and leek pie with a crispy flaky puff pastry top is an easy dinner that is a true family favourite. Made with leftover cooked chicken, it is on the table in just under an hour. This chicken pie is comfort food at its best, you will be asked to make it time and time again!

If my family could eat the same meal every night, it would be this creamy chicken pie with leeks. There is something about a homemade chicken pie that is guaranteed to be greeted with big smiles from young and old alike; whether this chicken leek pie made with leftover cooked chicken, or this chicken and ham pie.

Why We Love This Chicken Pie
- The chicken pie filling is made with the stock from cooking the leeks, which adds a richness and extra leek flavour.
- The crisp and golden puff pastry top goes so well with the soft chicken pie filling.
- It is a great recipe for leeks. In fact my son made sure we grew double the amount of leeks in the vegetable patch this year, purely with this pie in mind! The way they are growing I am thinking I will have to make some batches of leek and ricotta rolls too!
Ingredients Notes And Substitutions
(For the full list of ingredients and weights, please see the recipe card at the end of the post.)
- Chicken – leftover roast chicken or poached chicken. I often make it with cooked chicken marylands that I roast in the oven with the previous nights dinner.
- Puff Pastry – store bought puff pastry. In Australia I use a 24cm x 24cm frozen puff pastry sheet, weighing about 160g, but if you are in the UK you can use half a block of puff pastry, or half a sheet of ready rolled puff pastry. You can make your own shortcrust pastry if you prefer.
- Butter – I prefer to use unsalted butter and then add a pinch of salt to the sauce so I can easily control the salt levels.
- Flour – plain flour or all-purpose flour. I have also made this pie using wholemeal flour, which is still tasty but the sauce isn’t as smooth as when made with plain flour.
- Leeks – a fresh leek is boiled in salted water, and then some of this leek stock is used to make the sauce, adding extra leek flavour.
- Milk – whole milk / full cream milk creates a richer sauce which I prefer, however use semi skimmed / skim milk instead if you prefer.
- Thyme – fresh thyme is such a classic herb to use with chicken, and is delicious with leeks too.
- Worcestershire sauce – this adds a sweet, salty, unami flavour to the sauce.
- Mustard – mustard adds to the background flavour of the sauce. I love wholegrain mustard, I think it goes particularly well with the leeks; however you can substitute with Dijon mustard if you prefer.

How To Make This Chicken Leek Pie
(For the full detailed recipe, please see the recipe card at the end of the post.)
- Prepare and cook the leeks: slice the leek into approx 1 cm thick slices. Place into a colander and run under water, separating the rings to make sure any grit is washed away.
- Boil until tender, then drain – keep the cooking liquid!!!


- Make the bechamel: melt the butter then add the flour and cook for a minute to remove the raw flour taste, then add the milk slowly before adding the leek stock.
- Add the fresh thyme, salt and black pepper, mustard and Worcestershire sauce, and heat to thicken.


- Add the cooked chicken and leeks to the sauce, heat for 5 minutes. Pour into a baking dish and leave to cool slightly (if you place the puff pastry over the hot filling it will start to melt and be difficult to work with – I speak from experience!).
- Bake: Cover the pie filling with a sheet of puff pastry, brush with beaten egg and then, using a sharp knife, cut a couple of small holes into the top of the pastry to let out the steam and help prevent the pastry from becoming soggy. Bake until the pastry is golden.



FAQ
If you are wanting to make a chicken and leek pie with pastry on the top and bottom, I recomemnd using shortcrust pastry for the bottom of the pie and save the puff pastry for the top. Shortcrust pastry is sturdier and less likely to become soggy.
Brushing the puff pastry with beaten egg creates a wonderful shiny and golden finish when baked.
My Recipe Tips
- Wash the leeks well to make sure there is no grit in them.
- For a lump free sauce:
- Add the milk to the flour and butter paste a little at a time, whisking well inbetween each addition.
- Use a balloon whisk to whisk the sauce.
- No egg – brush the top of the puff pastry with a little milk. It won’t be quite as shiny or golden, but still gives a nice finish to the pie.
Serving Ideas
On those weeknights when time and energy is poor, I often don’t serve anything with this chicken pie, however to make more of a filling meal it is delicious served with:
Potatoes – mashed potatoes or roast potatoes.
Vegetables – boiled or air fried carrots, roast parsnips, broccoli, peas or green beans.

Storage
- The pie is best eaten fresh, however you can cook the leek up to 3 days ahead and keep the cooked leek leek stock covered in the fridge. You can also make the sauce without the chicken up to 3 days ahead.
Variations
- Using fresh chicken – if you want to make this chicken and leek pie with raw chicken rather than leftover cooked chicken – use 4 chicken thighs, cut into bitesize pieces, season with salt and pepper and fry in a tablespoon of olive oil for 5-10 minutes, until golden (it will still be raw on the inside). Make the sauce, then add the chicken with the mustard, and cook for 10 minutes. Make the pie as per the recipe, cooking until the chicken is cooked through and the puff pastry golden.
- Turkey and leek pie – swap the chicken for leftover turkey. I always make this pie after Christmas, adding a spoonful of leftover bread sauce to the leek sauce, and any last spoonfuls of cooked parsnips or carrots get thrown in too.
- Bacon – add 150g cooked bacon or prosciutto to the sauce with the chicken and leeks.
- Pastry – top with homemade shortcrust pastry rather than puff pastry.
