Ingredients for Chicken and Leek Pie

A great pie starts with great ingredients. The freshness of the leeks and the quality of the chicken stock you use will significantly impact the overall taste.

Main Ingredients List

For the filling:

• 600g cooked chicken, shredded or cut into chunks (leftover roast chicken works perfectly)
• 3 medium leeks, trimmed, cleaned, and sliced
• 50g unsalted butter
• 50g plain flour
• 400ml good-quality chicken stock
• 150ml double cream
• 1 tbsp Dijon mustard
• Salt and freshly ground black pepper
• Fresh thyme leaves (optional but recommended)

For the pastry:

• 500g ready-made shortcrust or puff pastry (or homemade if you prefer)
• 1 egg, beaten, for glazing

These quantities serve four to six people comfortably.

Key Ingredients Explained

Leeks: Leeks are the soul of this pie. They cook down to become silky and sweet, adding a gentle depth that onions cannot quite replicate. Always wash them thoroughly after slicing — grit has a way of hiding between the layers.

Double cream: This is what gives the filling its luxuriously smooth texture. You can use single cream or creme fraiche as a lighter alternative, but double cream produces the richest result.

Dijon mustard: Just a tablespoon, but it adds a quiet warmth and a slight sharpness that stops the filling from tasting flat. You will not identify it as mustard in the finished pie — it just makes everything taste better.

Ready-made pastry: There is absolutely no shame in using shop-bought pastry. Even professional bakers reach for it on busy days. A good all-butter shortcrust or puff pastry from the supermarket will give you excellent results.

Step-by-Step Cooking Instructions

Preparing the Chicken and Leek Filling

Melt the butter in a large, deep frying pan or saucepan over medium heat. Add the sliced leeks and cook gently for about 8 to 10 minutes, stirring occasionally, until they are completely soft and have reduced significantly. Do not rush this step — properly cooked leeks are sweeter and more flavourful.

Stir in the flour and cook for one minute, stirring constantly. This cooks out the raw flour taste and forms the base of your sauce.

Slowly add the chicken stock, a small amount at a time, stirring thoroughly after each addition to avoid lumps. After all the stock is mixed in, stir in the double cream and Dijon mustard.

Add the shredded chicken and fresh thyme, then season generously with salt and pepper, stirring to combine. Taste the filling and adjust the seasoning — it should taste well-seasoned and creamy with a good depth of flavour. Set it aside to cool before assembling.

Assembling the Pie

Preheat your oven to 200°C (180°C fan) or Gas Mark 6. Lightly grease a pie dish approximately 23 to 25cm in diameter.

If you are lining the base with pastry, roll it out on a lightly floured surface to a thickness roughly equal to a pound coin. Line the base and sides of your pie dish, letting a little overhang the edges.

Spoon the cooled filling into the dish. If the filling is still hot, it will start to melt the pastry and soften the base — this is why cooling matters.

Roll out your pastry lid and lay it carefully over the filling. Press the edges together to seal, then trim away any excess with a sharp knife. Crimp the edges with a fork or your fingers. Cut two or three small slits in the top to allow steam to escape, then brush generously with beaten egg.

Bake for 30 to 35 minutes until the pastry is deep golden, and the filling is bubbling through the slits.

Making the Perfect Pie Crust

Shortcrust vs Puff Pastry

Both work well in this easy chicken pie, but they give quite different results.

Shortcrust pastry produces a firmer, more crumbly crust with a satisfying snap. It is slightly richer and less flaky, making it a great choice if you want the pastry to hold its shape neatly when sliced.

Puff pastry gives you those dramatic, flaky layers that shatter beautifully when you cut into them. It rises impressively in the oven, giving the pie a more restaurant-style appearance. If you are making this for guests, puff pastry tends to look more impressive.

Many home cooks use shortcrust for the base and puff for the lid — the best of both worlds.

Tips for a Crispy and Golden Crust

• Always cool your filling completely before adding the pastry lid. A hot filling creates steam that softens the pastry from the inside.
• Brush the egg wash right to the edges, but avoid letting it drip down the sides of the dish — this can prevent the pastry from rising evenly.
• Place your pie dish on a preheated baking sheet. The direct heat helps crisp the base.
• If the top starts browning too quickly before the base is cooked, loosely cover it with foil for the final 10 minutes.

Tips for a Creamy and Flavorful Filling

Pro Cooking Tips

Do not skip cooking the leeks slowly. High heat will make them watery rather than sweet and tender. Low and slow is the right approach here.

Always season the filling before adding it to the pie. Pastry does not add any seasoning, so the filling needs to carry all the flavour on its own. Taste it multiple times and adjust as needed.

Use leftover roast chicken if you have it. The slightly richer flavour of already-roasted meat adds considerably more depth than plain poached chicken breast.

Common Mistakes to Avoid

Errors and How to Fix Them

Soggy bottom pastry: The filling was too hot or too wet when assembled. Let it cool completely and make sure the sauce is thick enough before spooning it in.

Filling tastes bland: Underseasoned or the stock was weak. Use a good-quality stock and taste the filling generously before assembling.

Pastry shrinks during baking: This usually happens when the pastry is stretched to fit the dish rather than draped gently. Let it relax into the dish without pulling it.

Filling bubbles over the sides: The dish is too small or overfilled. Leave a small gap between the filling and the rim when assembling.

Variations and Substitutions

Healthier and Dairy-Free Options

To make a lighter version of this chicken and leek pie, swap the double cream for crème fraîche or a high-quality, low-fat cream substitute. The sauce will be a touch less indulgent, but it will still be creamy and enjoyable.

For a dairy-free version, use olive oil instead of butter to cook the leeks, a dairy-free spread to make the roux, and full-fat oat cream or coconut cream in place of double cream. The flavour profile changes slightly but remains delicious.

For added vegetables, mushrooms, peas, and diced carrots all work well stirred into the filling. They bulk up the pie without overpowering the chicken and leek combination.

How to Store and Reheat Chicken and Leek Pie

Storage and Freezing Tips

Leftover pie keeps well in the refrigerator for up to three days. Store it covered tightly with foil or in an airtight container.

To reheat, place it in an oven at 180°C for 15 to 20 minutes until heated through. Avoid microwaving if you want to preserve the pastry’s crispness — it will make the crust soft and chewy.

This homemade savoury pie also freezes well. You can freeze it either before or after baking. If freezing before baking, assemble the pie completely, wrap tightly, and freeze for up to three months. Bake from frozen at 180°C for 50-60 minutes, covering with foil for the first 30 minutes. If freezing after baking, cool completely first, then freeze and reheat as above.

What to Serve with Chicken and Leek Pie

Best Side Dishes

A pie this substantial does not need elaborate accompaniments. Simple sides work best and let the pie itself remain the main attraction.

• Mashed potato: Buttery, creamy mash alongside a slice of this pie is a combination that simply cannot be argued with.
• Steamed green vegetables: Tenderstem broccoli, green beans, or savoy cabbage all cut through the richness of the filling beautifully.
• Roasted root vegetables: Carrots, parsnips, and sweet potato roasted with a little honey and thyme complement the pie’s savoury notes.
• Simple green salad: If you want a lighter meal, a crisp salad with a sharp vinaigrette provides a welcome contrast to the creamy filling.

FAQs

Can I use raw chicken instead of cooked? Yes, but you will need to cook it first. Raw chicken should never go into the pie filling uncooked. Poach chicken breasts or thighs in stock until cooked through, then shred and use as directed. The poaching liquid can also be used as part of your stock for added flavour.

Can I make Mary Berry’s chicken and leek pie ahead of time? Absolutely. The filling can be made a day in advance and stored in the refrigerator. Assemble and bake the pie fresh on the day you plan to serve it for the best pastry results.

What size pie dish should I use? A 23 to 25cm round pie dish with sides approximately 5cm deep works well for this quantity. A standard oval pie dish of similar volume is also fine.

Can I make individual pies instead of one large one? Yes, and individual pies are actually ideal for freezing and reheating. Use 4 to 6 individual pie dishes or ramekins and reduce the baking time to around 20 to 25 minutes.

My sauce turned lumpy — how do I fix it? This usually happens when the stock is added too quickly. If your sauce has lumps, pass it through a fine sieve and return it to the pan, then continue cooking. Next time, add the stock very gradually and stir constantly.
