My Definitive Chicken and Mushroom Pie
A truly comforting and classic dish, this chicken and mushroom pie features a rich, creamy filling encased in crisp, golden pastry. It's a proper supper dish that never fails to please.
There are few things in the culinary world quite so reassuring as a proper, homemade pie steaming gently on the kitchen table. It speaks of home, of comfort, and of taking the time to do things properly. A chicken and mushroom pie, in particular, sits at the very heart of British home cooking, and getting it right is one of the most satisfying achievements for any cook.
The secret, as with so many things, lies in paying attention to the details. It's a partnership of two key elements: a rich, savoury filling with tender chicken and earthy mushrooms, bound in a beautifully seasoned, creamy sauce; and the pastry, which must be a crisp, golden, and flaky lid, not a pale, soggy apology. Each component must be perfect in its own right before they are brought together.
So, while it may seem like a bit of a project, I assure you it's a straightforward and deeply rewarding process. Follow these steps carefully, and you will have a pie on your hands that will make you, your family, and your guests extremely happy. This is how to cook, with confidence, a truly magnificent chicken and mushroom pie.
Why You'll Love This Recipe
- Cooling the filling completely before adding the pastry is non-negotiable. This single step prevents the pastry from steaming from underneath, ensuring a crisp base and avoiding the dreaded 'soggy bottom'.
- Using boneless, skinless chicken thighs provides more flavour and moisture than breast meat. They stand up to the slow cooking of the filling without drying out, resulting in perfectly tender chicken.
- Creating a classic roux-based sauce (béchamel) provides a stable, creamy, and flavourful foundation that won't split or become watery during baking.
Ingredients
- About 600g boneless, skinless chicken thighs, cut into 2.5cm (1 inch) chunks
- 25g unsalted butter
- 1 tablespoon olive oil
- 1 large onion, finely chopped
- 2 cloves garlic, crushed or finely chopped
- 250g chestnut mushrooms, wiped and thickly sliced
- 50g plain flour
- 400ml good quality chicken stock, preferably hot
- 150ml double cream or crème fraîche
- 1 tablespoon fresh thyme leaves, or 1 teaspoon dried
- 2 tablespoons chopped fresh parsley
- Salt and freshly milled black pepper
- 375g block of all-butter puff pastry (or good quality shortcrust)
- 1 medium egg, beaten with a pinch of salt for glazing
Equipment Needed
Large, heavy-based casserole dish or saucepan · 2-pint (1.2 litre) pie dish · Rolling pin · Pastry brush · Sharp knife · Baking tray · Slotted spoon · Measuring jug
Step-by-Step Instructions
- Begin with the filling. Place a large, heavy-based casserole dish or saucepan over a medium heat. Add the butter and olive oil. Once the butter is foaming, add the chopped onion and cook gently for 8-10 minutes until soft and translucent, but not coloured.
- Increase the heat slightly, add the chicken pieces to the pan, and stir to brown them on all sides. You may need to do this in two batches to avoid overcrowding the pan, which would cause the chicken to steam rather than fry. Once browned, remove the chicken with a slotted spoon and set aside.
- Add the sliced mushrooms to the same pan and cook for 5-7 minutes until they have released their liquid and are beginning to brown. Add the crushed garlic and thyme and cook for another minute until fragrant.
- Now, return the chicken to the pan with the mushrooms. Sprinkle over the 50g of plain flour and stir well to coat everything, cooking for a minute or two. This cooks out the raw taste of the flour.
- Gradually pour in the hot chicken stock, a little at a time, stirring constantly to create a smooth, thick sauce. Once all the stock is incorporated, bring it to a gentle simmer and let it bubble away for 5 minutes, stirring occasionally.
- Reduce the heat to its lowest setting, stir in the double cream or crème fraîche, the chopped parsley, and a generous seasoning of salt and pepper. Let it tick over for another 5 minutes. Taste and adjust the seasoning if needed. The filling should be well-seasoned and creamy.
- This next step is crucial: transfer the entire filling to a shallow dish, spread it out to increase the surface area, and allow it to cool completely. You can speed this up by placing it in the fridge once it's no longer hot.
- When the filling is cold, preheat your oven to 200°C (180°C Fan, Gas Mark 6). Spoon the cold filling into a 2-pint (1.2 litre) pie dish.
- On a lightly floured surface, roll out the pastry until it is about the thickness of a pound coin and large enough to cover your pie dish with a little overhang. Brush the rim of the pie dish with a little of the beaten egg.
- Lay the pastry over the filling, pressing it down onto the egg-washed rim to seal. Trim the excess pastry with a sharp knife, then use a fork or your fingers to 'crimp' the edges for a decorative finish. If you have pastry trimmings, you can make a few leaves to decorate the top.
- Brush the top of the pie all over with the beaten egg glaze. Make a couple of small slits in the centre of the lid to allow steam to escape.
- Place the pie on a baking tray (to catch any potential spills) and bake for 30-35 minutes, or until the pastry is puffed up, golden-brown, and crisp, and the filling is piping hot.
Delia's Notes from the Kitchen
The absolute, non-negotiable secret to a perfect pie with a crisp pastry lid is to allow the filling to become completely, stone-cold cool before you even think about topping it. I know it requires patience, and it's tempting to rush, but this is the difference between a good pie and a truly great one. I often make my filling the day before, which not only guarantees it's cold but also allows the flavours to develop beautifully overnight. Trust me on this; it is the most important step in the entire recipe.
How to Store & Reheat
To store, allow the pie to cool completely, then cover tightly with foil or cling film and refrigerate for up to 3 days. To reheat, place the pie (uncovered) in an oven preheated to 180°C (160°C Fan) for 20-25 minutes, until the pastry is crisp and the filling is thoroughly heated through. You can also freeze the pie, either unbaked or baked. To cook from frozen (unbaked), add 20-25 minutes to the original cooking time.
Frequently Asked Questions
Why did my pastry lid go soggy?
The most common reason for a soggy pastry lid is putting it on top of a warm filling. The steam from the filling gets trapped and prevents the pastry from becoming crisp. It is absolutely essential that the filling is completely cold before you top it with the pastry.
Can I use leftover roast chicken?
Yes, it's an excellent way to use leftovers. Simply skip the step of browning the raw chicken. Make the sauce with the onions and mushrooms, and then stir in about 400-500g of shredded, cooked chicken at the same time as you add the parsley and cream.
My sauce was lumpy. What did I do wrong?
Lumps in the sauce usually occur when making the roux. It happens when the liquid is added too quickly to the flour and butter mixture. The key is to add the stock very gradually at first, stirring vigorously to incorporate it into a smooth paste before adding more liquid.
Can I prepare parts of this pie in advance?
Certainly. The filling can be made up to two days in advance and kept covered in the refrigerator. This is actually my preferred method as it guarantees the filling is cold. You can then simply assemble and bake the pie when you are ready to eat.
How do I stop the filling from bubbling over in the oven?
There are two tips for this. Firstly, don't overfill the pie dish; leave a small gap at the top. Secondly, always place your pie on a baking tray. This not only catches any spills but also helps to cook the base of the pie more effectively.
