Chicken and leek pie is British comfort food at its best.
Tender pieces of chicken and sweet, softened leeks are folded into a creamy herb sauce, then tucked beneath a crisp, golden layer of puff pastry.
It’s rich without being overly heavy, familiar without being boring and exactly the sort of dinner that feels right when the evenings start getting colder.
Chicken and leek is also one of those flavour combinations that appears again and again in British cooking. Leeks have a gentler, sweeter flavour than ordinary onions, which makes them particularly good with chicken and cream.
For American cooks, there’s nothing especially difficult about making a proper chicken and leek pie. You can use chicken thighs or breasts, ordinary American chicken broth and store-bought frozen puff pastry.
The biggest trick is simply allowing the filling to cool before putting the pastry on top.
Here’s how to make a classic British-style chicken and leek pie in an American kitchen.
What Is British Chicken and Leek Pie?
Chicken and leek pie is a savoury British pie filled with chicken and leeks in a creamy sauce.
Some versions are completely enclosed in pastry, while others — including ours — use a pastry lid over a pie dish filled with the chicken mixture.
Using pastry only on top makes the recipe considerably easier and allows us to use store-bought puff pastry without worrying about a soggy pastry base.
The filling usually includes chicken stock, cream and herbs.
You’ll also find variations containing bacon, ham, mushrooms, mustard or cheese.
We’re keeping this version relatively simple so the chicken and leeks remain the stars.
What Do Leeks Taste Like?
Leeks belong to the same family as onions and garlic, but their flavour is milder and slightly sweeter.
Once slowly cooked in butter, they become beautifully soft.
That’s why they work so well with chicken.
American supermarkets usually sell leeks individually or in bunches in the produce section.
Look for leeks with firm white stalks and fresh-looking green tops.
Which Part of a Leek Do You Eat?
For this pie, use the white and pale green portions.
The dark green leaves are considerably tougher.
Don’t necessarily throw those away — they’re excellent for flavouring homemade stock.
Trim off the roots and dark green tops before slicing the remaining leek.
How Do You Clean Leeks?
Leeks have layers that can trap quite a surprising amount of dirt and grit.
After trimming them, slice the leeks lengthwise and rinse thoroughly between the layers.
Alternatively, slice them first, place the pieces in a large bowl of cold water and swish them around.
Allow the dirt to sink to the bottom, then lift the leeks out rather than pouring everything through a colander and dumping the grit back over them.
Should I Use Chicken Thighs or Chicken Breasts?
Either works.
I prefer boneless, skinless chicken thighs because they stay juicy and tender in the creamy filling.
Chicken breasts produce a slightly leaner pie but can dry out more easily.
If using breasts, be especially careful not to overcook them during the initial cooking stage because they’ll continue cooking in the oven.
Can I Use Leftover Roast Chicken?
Absolutely.
Chicken and leek pie is an excellent way to use leftover roast chicken.
You’ll need approximately 3 cups (450–500 g) of cooked chicken, cut or torn into bite-sized pieces.
Skip the initial chicken-cooking step and add the cooked chicken once you’ve made the sauce.
It’s also a wonderful use for leftover rotisserie chicken.
What Puff Pastry Should Americans Use?
Frozen puff pastry from an American supermarket works perfectly well.
Brands vary in size and thickness, so don’t worry if your pastry sheet doesn’t exactly match the dimensions given in a British recipe.
You simply need enough pastry to cover the top of your baking dish with a small amount of overhang.
Thaw it according to the package directions, but keep it cold until you’re ready to use it.
Warm puff pastry becomes soft and difficult to handle.
Traditional British Chicken and Leek Pie Recipe
Prep Time: 30 minutes
Cooling Time: 20–30 minutes
Bake Time: 30–35 minutes
Serves: 6
Equipment
- Large skillet or Dutch oven
- 9-inch (23 cm) deep pie dish or approximately 2-quart baking dish
- Cutting board
- Sharp knife
- Wooden spoon
- Pastry brush
Ingredients
For the Filling
- 1½ lb (680 g) boneless, skinless chicken thighs or breasts
- 1 teaspoon fine salt, divided
- ½ teaspoon freshly ground black pepper
- 1 tablespoon olive or neutral oil
- 3 tablespoons (42 g) unsalted butter
- 2 large leeks, white and pale green portions only, thoroughly cleaned and sliced
- 2 garlic cloves, minced
- ¼ cup (30 g) all-purpose flour
- 1½ cups (360 ml) chicken stock or broth
- ½ cup (120 ml) heavy cream
- 1 teaspoon Dijon mustard
- 1 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
- 2 tablespoons chopped fresh parsley
- ½ teaspoon Worcestershire sauce, optional
For the Pastry
- 1 sheet frozen puff pastry, approximately 8–10 oz (225–285 g), thawed according to package directions
- 1 large egg
- 1 tablespoon water
Instructions
1. Prepare the Chicken
Cut the chicken into irregular bite-sized pieces, approximately 1½ inches (4 cm) across.
Season with about ½ teaspoon of the salt and the black pepper.
Brit & Skillet Tip
Don’t cut the chicken into lots of perfectly tiny cubes.
Slightly larger, irregular pieces stay juicier during cooking and give the finished pie a much more satisfying homemade texture.
2. Brown the Chicken
Heat the oil in a large skillet or Dutch oven over medium-high heat.
Add the chicken in a single layer.
Cook for approximately 4–5 minutes, turning occasionally, until lightly browned.
The chicken doesn’t need to be completely cooked through at this point.
Transfer it to a plate.
3. Cook the Leeks
Reduce the heat to medium-low.
Add the butter to the same pan.
Once melted, add the sliced leeks and remaining salt.
Cook gently for approximately 8–10 minutes, stirring occasionally.
The leeks should become soft and sweet without developing much colour.
Add the garlic and cook for another 30 seconds.
Brit & Skillet Tip
Don’t rush the leeks.
Cooking them gently rather than aggressively frying them brings out their natural sweetness and gives the filling its characteristic flavour.
4. Add the Flour
Sprinkle the flour over the softened leeks.
Stir thoroughly and cook for approximately 1–2 minutes.
The mixture will look quite thick.
This flour will eventually thicken the chicken stock and cream into our pie sauce.
5. Add the Chicken Stock
Gradually pour in the chicken stock while stirring continuously.
Add a little at first and stir until smooth before adding more.
This helps prevent lumps.
Once all the stock has been incorporated, bring the mixture to a gentle simmer.
6. Add the Cream and Seasonings
Stir in the heavy cream, Dijon mustard, thyme and optional Worcestershire sauce.
Return the chicken and any juices on the plate to the pan.
Simmer gently for approximately 5–7 minutes, stirring occasionally.
The sauce should become creamy and thick enough to coat the chicken.
Stir in the parsley.
Taste and adjust the salt and pepper if necessary.
How Thick Should the Filling Be?
The sauce should be thicker than an ordinary cream sauce.
Drag your wooden spoon through the pan.
You should briefly be able to see the bottom before the sauce flows back into place.
Remember that the filling will loosen slightly as the chicken and leeks release moisture in the oven.
If it seems watery now, continue simmering for another few minutes.
7. Transfer to the Pie Dish
Spoon the filling into your pie dish or baking dish.
Spread it evenly.
Now leave it to cool for approximately 20–30 minutes.
It doesn’t need to become refrigerator-cold, but it shouldn’t be steaming hot when the pastry goes on.
Brit & Skillet Tip
This is one of the most important steps in the entire recipe.
Putting cold puff pastry directly over piping-hot filling begins melting the butter in the pastry before it reaches the oven.
That can prevent the pastry from puffing properly.
Cool filling + cold pastry = a much better pie.
8. Preheat the Oven
While the filling cools, preheat the oven to 400°F (200°C).
9. Add the Puff Pastry
Keep the puff pastry refrigerated until you’re ready for it.
Place the pastry over the cooled filling.
Trim away excessive overhang, leaving approximately ½–1 inch (1–2.5 cm) around the edge.
Gently press the pastry against the rim of the dish.
You can crimp the edges with your fingers or a fork if you’d like.
10. Cut Steam Vents
Using the tip of a sharp knife, cut 2–3 small slits in the centre of the pastry.
These allow steam to escape while the pie bakes.
11. Add the Egg Wash
Beat the egg with 1 tablespoon of water.
Brush a thin layer over the puff pastry.
Avoid allowing large amounts of egg wash to run down the cut edges of the pastry, which can glue the layers together and interfere with the rise.
12. Bake
Place the pie on a baking sheet to catch any bubbling filling.
Bake at 400°F (200°C) for approximately 30–35 minutes.
The pastry should be well risen, crisp and deeply golden.
The filling should be bubbling around the edges.
13. Rest Before Serving
Let the pie rest for approximately 10 minutes before serving.
The filling will be extremely hot straight from the oven and will thicken slightly as it rests.
What Is the Difference Between British Double Cream and American Heavy Cream?
British double cream contains more fat than American heavy cream and has a thicker consistency.
But you don’t need to hunt down imported double cream for this recipe.
Ordinary American heavy whipping cream or heavy cream works perfectly well.
Because we’re thickening the sauce with flour, the lower fat content isn’t a problem.
Can I Use Half-and-Half?
Yes, although the filling won’t be quite as rich.
You may need to simmer the sauce slightly longer to achieve the proper consistency.
I wouldn’t recommend ordinary low-fat milk as a direct substitute because the sauce can become too thin.
Can I Add Bacon?
Yes.
Chicken, leek and bacon is another classic combination.
Cut approximately 4 oz (115 g) bacon into small pieces and cook it in the pan before browning the chicken.
Remove the crisp bacon, cook the chicken in some of the rendered fat and return the bacon when you add the chicken to the sauce.
If your bacon is particularly salty, reduce the added salt accordingly.
Can I Add Mushrooms?
Absolutely.
Add approximately 8 oz (225 g) sliced mushrooms after the leeks have softened.
Cook until the mushrooms release their liquid and begin to brown before continuing with the flour.
This creates an earthier, more savoury version of the pie.
Can I Add Peas?
Yes.
Stir approximately 1 cup (140 g) frozen peas into the filling immediately before transferring it to the pie dish.
There’s no need to thaw them first.
Can I Use Shortcrust Pastry?
Yes.
Puff pastry creates the light, flaky top we’re using here, but shortcrust pastry is another traditional option.
If you prefer a sturdier, more substantial pastry crust, shortcrust works beautifully.
Why Didn’t My Puff Pastry Rise?
The most common reasons are:
- The filling was too hot
- The pastry became warm before baking
- The oven wasn’t fully preheated
- Too much egg wash ran over the pastry edges
- The pastry was rolled too thinly
Keep puff pastry cold and put the assembled pie into a properly heated oven as soon as you’ve added the pastry.
Why Is My Chicken and Leek Pie Watery?
The filling probably wasn’t thick enough before it went into the pie dish.
Leeks and chicken can both release additional moisture during baking.
Make sure the sauce is distinctly thick and creamy before cooling it.
If you’ve added mushrooms, cook away their excess liquid before adding the flour.
Why Is My Chicken Dry?
Chicken breasts are more prone to drying out than thighs.
Remember that we’re only lightly cooking the chicken before it goes into the sauce because it will continue cooking in the oven.
If you want the most forgiving option, use boneless skinless chicken thighs.
Can I Make Chicken and Leek Pie Ahead?
Yes.
Prepare the filling up to one day ahead and refrigerate it in the pie dish.
When you’re ready to bake, add the cold puff pastry and egg wash.
You may need to add approximately 5–10 minutes to the baking time if the filling is refrigerator-cold.
Don’t assemble the puff pastry lid a full day ahead because it can absorb moisture from the filling and lose some of its crispness.
What to Serve With Chicken and Leek Pie
This pie is lovely with:
- Mashed potatoes
- Buttered peas
- Steamed green beans
- Roasted carrots
- Broccoli
- Simple green salad
Because the filling is already creamy, you don’t necessarily need additional gravy.
For a particularly hearty British dinner, serve it with seasonal vegetables and mashed potatoes.
How to Store Chicken and Leek Pie
Allow leftovers to cool, then cover and refrigerate for up to approximately 3 days.
Reheat individual portions in a 350°F (175°C) oven until thoroughly hot.
The microwave works too, although the puff pastry will lose some of its crispness.
Can You Freeze Chicken and Leek Pie?
Yes.
For the best result, freeze the filling separately before adding the puff pastry.
Cool the filling completely and transfer it to a freezer-safe container.
Freeze for up to approximately 3 months.
Thaw overnight in the refrigerator, place in your pie dish and add fresh puff pastry before baking.
You can also freeze a fully assembled unbaked pie, but results vary depending on the brand of puff pastry you’re using.
Can I Use Rotisserie Chicken?
Yes, and it makes this recipe considerably quicker.
Use approximately 3 cups (450–500 g) shredded or chopped cooked chicken.
Make the leek and cream sauce as directed, then stir the cooked chicken into the finished sauce just long enough to warm through.
Cool before adding the pastry.
A Proper British Chicken Pie
There’s something particularly comforting about breaking through a crisp puff-pastry lid and finding a creamy chicken filling underneath.
Chicken and leek pie isn’t complicated food.
Its appeal comes from getting a few simple things right: sweet leeks cooked gently in butter, tender chicken, a properly seasoned creamy sauce and pastry that’s allowed to become genuinely crisp and golden.
And because store-bought puff pastry does most of the difficult work, it’s far easier to make at home than its appearance suggests.
Serve it with mashed potatoes and peas on a cold evening and you’ve got the sort of uncomplicated British dinner that’s very difficult not to love.
