Quick answer: chicken and leek pie
- Prep: 25 minutes
- Cook: 45 minutes (sauce + bake)
- Serves: 4
- Oven: 200°C / fan 180°C / gas 6
- Meat: 600–700g diced chicken breast (or thigh)
Ingredients (serves 4)
- 600–700g chicken breast, diced (from Chicken Breast 1kg)
- 2 large leeks (about 400g), trimmed, washed and sliced
- 1 medium onion, finely chopped
- 2 garlic cloves, crushed
- 40g butter
- 2 tbsp plain flour
- 400ml chicken stock
- 100ml double cream (or whole milk for a lighter sauce)
- 1 tsp Dijon mustard
- 1 tsp fresh thyme leaves (or ½ tsp dried)
- Salt and freshly ground black pepper
- 320g ready-rolled shortcrust or puff pastry
- 1 egg, beaten, for glazing
Method
- Pat the diced chicken dry with kitchen paper and season lightly with salt and pepper. Wet chicken steams instead of browning.
- Melt half the butter in a wide pan over medium heat. Add the onion and leeks with a pinch of salt. Soften for 8–10 minutes until sweet and floppy — do not rush this step or the pie will taste raw-onion sharp.
- Stir in the garlic for 1 minute. Push the vegetables to the side, add the remaining butter, and brown the chicken in batches until the pieces are opaque on the outside.
- Sprinkle over the flour and stir for 1 minute so it coats the chicken and leeks. Gradually pour in the stock, stirring until you have a smooth, pourable sauce.
- Simmer gently for 8–10 minutes until the chicken is cooked through — no pink meat, juices run clear, and a probe in the thickest cube reads at least 75°C. Stir in the cream, mustard and thyme. Taste and season. Cool until just warm (spread in a shallow tray to speed this up).
- Heat the oven to 200°C (fan 180°C, gas 6). Tip the filling into a 1.5–2 litre pie dish. It should come close to the rim without overflowing.
- Unroll the pastry, drape it over the dish, and trim with a 1–2cm overhang. Crimp the edges, cut a steam hole in the centre, and brush with beaten egg. Use scraps for leaves if you like.
- Bake for 25–35 minutes until the pastry is deep golden and you can see the filling bubbling at the steam hole. Rest 5–10 minutes so the sauce thickens for cleaner slices.
Butcher’s tips for a non-soggy pie
Cool the filling. Hot sauce under pastry is the number-one reason lids collapse. If your sauce looks thin after simmering, reduce it a few more minutes before creaming — pastry lids hate watery gravy. Wash leeks thoroughly: grit hides between the layers, so slit them lengthways and rinse under a cold tap. For a deeper chicken flavour without more cream, save a spoon of roasting juices from a previous bird or use a good stock cube dissolved in hot water. Diced breast from Diced Chicken Breast 1kg saves knife work if you are short on time; still dry and season before the pan.
Shortcrust gives a sturdy British pub-pie lid. Puff pastry is lighter and rises higher — chill the topped pie for 10 minutes before baking if your kitchen is warm so the butter layers stay distinct. Either way, egg wash is not optional if you want that bakery shine.
What to serve with chicken and leek pie
Buttery mash or boiled new potatoes, buttered greens or peas, and a jug of the leftover sauce if you made extra. A sharp watercress salad cuts the cream. Leftovers reheat well: oven at 170°C fan until piping hot in the centre, or microwave individual portions then crisp the pastry under a hot grill for a minute. Keep refrigerated and eat within two days; freeze portions if you cooked ahead.

Why this chicken and leek pie recipe works
Leeks bring a gentle sweetness that onion alone cannot. Mustard and thyme stop the cream sauce tasting flat. Cooking the chicken fully in the pan before baking means you are only heating and browning pastry in the oven — safer and more reliable than raw chicken under a lid. Buying a full kilo of breast means tomorrow’s fajitas or meal-prep dice are already sorted. That is the Meatsupermarket way: one pack, two good meals, skip the middle man.
FAQ
Can I use chicken thighs instead of breast?
Yes. Chicken thighs work brilliantly in a pie — they stay juicier after baking. Dice the meat, simmer until cooked through (no pink, juices clear), then cool before assembling the pie so the pastry does not go soggy.
Should the filling be cold before I put the pastry on?
Ideally yes. A hot filling steams the underside of the pastry and can make it soft. Cool the chicken and leek sauce until just warm (or fridge-cold), then top and bake.
Do I need to blind-bake the pastry?
Not for a simple top-crust pie in a deep dish. If you prefer a full double crust, chill the base pastry and bake a few minutes before filling so the bottom stays crisp.
Can I freeze chicken and leek pie?
Yes. Assemble, wrap well, and freeze unbaked for up to a month, or freeze leftovers once cooled. Bake from frozen at 180°C fan until the centre is piping hot (add 15–20 minutes).
What pastry is best for a British chicken and leek pie?
Ready-rolled shortcrust is traditional and sturdy. Puff pastry gives a lighter, flaky top — brush with egg wash either way for a golden finish.
