Chicken and Mushroom Pie
Why this recipe works
- Deep savoury flavour: Browning the chicken, softening the leek and cooking down the mushrooms builds a well-rounded base before the sauce is added.
- Creamy, stable filling: Flour thickens the stock before the cream and mustard go in, giving the pie a sauce that coats the chicken rather than turning runny.
- Flaky pastry contrast: Cooling the filling briefly before topping helps the puff pastry rise properly and stay crisp against the rich filling.

Timing notes
- Cool before topping: Let the filling cool briefly in the baking dish before adding the pastry; very hot filling can soften the butter layers and reduce the rise.
- Rest before serving: A short rest after baking helps the sauce thicken slightly, making the pie easier to serve neatly.
Texture tips
- For a thicker filling: Simmer the sauce until it coats the chicken well before baking; it should not look watery in the pan.
- For a better pastry lid: Cut a small steam hole in the centre so moisture can escape and the pastry can puff and brown evenly.
Make-ahead tips
- Prepare the filling ahead: The chicken and mushroom filling can be cooked, cooled and refrigerated before assembling with pastry later.
- Reheat gently: Reheat leftovers in a 180°C (355°F) oven until piping hot so the pastry has a chance to crisp again.
- Freezing option: Cool the baked pie completely, wrap well and freeze; thaw overnight in the fridge before reheating.
Ingredient notes
- Use chicken thighs: Boneless thighs stay tender and juicy in the creamy sauce, making them well suited to pie fillings.
- Choose all-butter pastry if possible: All-butter puff pastry gives a richer flavour and a more delicate, flaky lid.
- Mustard adds balance: Dijon mustard cuts through the creaminess and gives the sauce a subtle savoury sharpness rather than obvious heat.

Ingredients
Instructions
- Heat the oven to 200°C (390°F). Cut the chicken into bite-size pieces, then season with the salt and pepper.
- Heat the olive oil in a large frying pan over medium-high heat. Brown the chicken in batches for 4 to 5 minutes per batch until lightly golden, then transfer to a plate.
- Reduce the heat to medium and add the butter to the pan. Slice and wash the leek well, then cook for 6 to 8 minutes until softened but not coloured.
- Slice the mushrooms and add them to the pan. Cook for 8 to 10 minutes, stirring occasionally, until the mushrooms have released their liquid and it has mostly evaporated.
- Strip the thyme leaves from the sprigs and stir them in. Sprinkle over the flour and cook for 1 minute, stirring, to remove the raw flour taste.
- Gradually whisk in the chicken stock until smooth, then bring to a gentle simmer. Cook for 3 to 4 minutes until thickened enough to coat the back of a spoon.
- Lower the heat and stir in the double cream and Dijon mustard. Return the chicken and any resting juices to the pan and warm through for 2 to 3 minutes until the chicken is cooked through and the sauce is creamy.
- Tip the filling into a baking dish and leave to cool for 10 minutes so the pastry stays flaky. Lightly beat the egg in a small bowl.
- Lay the puff pastry over the dish and trim to fit, then crimp the edges to seal. Brush the top with the beaten egg and cut a small steam hole in the centre.
- Bake for 25 minutes until the pastry is puffed and deep golden and the filling is bubbling at the edges. Rest for 5 minutes before serving so the sauce thickens slightly.
Recipe notes
Tips
- Cool the filling briefly before adding the puff pastry; a hot filling can melt the butter in the pastry and stop it puffing properly.
- If the sauce looks a little loose before baking, simmer it for an extra 1 to 2 minutes; it should coat the chicken rather than pool in the pan.
- If serving vulnerable groups, ensure the chicken is cooked until piping hot throughout and the juices run clear.
Substitutions
- Replace Dijon mustard with whole-grain mustard for a milder heat and a coarser texture.
- Replace cremini mushrooms with button mushrooms for a lighter flavour.
- Replace double cream with crème fraîche for a slightly tangier sauce, and keep the heat low to prevent splitting.
Storage
- Refrigerate up to 3 days
- Cool completely, then cover and refrigerate. Reheat in a 180°C (355°F) oven for 20 to 25 minutes until piping hot; if freezing, wrap well and freeze for up to 2 months, then thaw overnight in the fridge before reheating.
