Amelia Grace Chicken and mushroom is one of those pairings that never disappoints, and baked into a pie under crisp, golden pastry, it becomes proper comfort food.
This is a rich, creamy filling, built around tender chicken and a generous amount of mushrooms cooked until deeply golden, all brought together in a velvety sauce.
It’s the kind of pie I make when I want something that feels properly homely, and it’s just as good the next day as it is fresh from the oven.
Why Cooking the Mushrooms Until Properly Golden Matters
Mushrooms release a surprising amount of liquid as they cook, and how you handle that liquid makes a real difference to the finished pie.
Cooking mushrooms over a high enough heat until all that released liquid has fully evaporated, and the mushrooms themselves have turned deeply golden, concentrates their flavour enormously compared to mushrooms that are only lightly cooked.
Rushing this stage, or crowding the pan so the mushrooms steam rather than fry, leaves you with pale, watery mushrooms that dilute the sauce and taste comparatively bland.

How to Make Delia Smith Chicken and Mushroom Pie — Step by Step
Step 1 — Brown the Chicken
Melt half the butter in a large pan over medium-high heat. Add the chicken and cook for 5–6 minutes, until lightly browned on all sides. Remove and set aside.
Step 2 — Cook the Mushrooms
Add the remaining butter to the pan and cook the mushrooms over a fairly high heat for 8–10 minutes, until all their liquid has evaporated and they’re deeply golden.
Step 3 — Soften the Onion
Add the onion to the pan and cook for a further 5 minutes, until softened. Stir in the garlic for a final minute.
Step 4 — Add the Flour
Stir in the flour and cook for 1 minute, coating everything evenly.
Step 5 — Add the Stock Gradually
Gradually whisk in the chicken stock, a little at a time, until smooth.
Step 6 — Return the Chicken
Return the browned chicken to the pan and bring to a gentle simmer. Cover and cook for 15–20 minutes, until the chicken is cooked through.
Step 7 — Finish the Sauce
Stir in the double cream, Dijon mustard and thyme leaves. Season with salt and pepper and simmer for a further 2–3 minutes to thicken slightly.
Step 8 — Cool the Filling
Leave the filling to cool to room temperature before assembling the pie.
Step 9 — Top with Pastry and Bake
Preheat your oven to 200°C (180°C fan / Gas 6). Transfer the cooled filling to a pie dish and top with the puff pastry, trimming and crimping the edges and cutting a small slit for steam. Brush with beaten egg and bake for 25–30 minutes, until deep golden and well risen.
My Top Tips for the Best Delia Smith Chicken and Mushroom Pie
Cook the mushrooms properly until golden. This step concentrates their flavour enormously, so don’t rush it, even though it takes a bit longer than you might expect.
Don’t overcrowd the pan when cooking the mushrooms. Too many mushrooms at once means they steam rather than fry, so cook in batches if needed to get that proper golden colour.
Let the filling cool before adding the pastry. This keeps the pastry butter cold right up until baking, which gives you a much better, flakier rise.
Add the stock gradually at first. This helps prevent lumps forming in the sauce, giving you a smooth, glossy filling.
Cut a proper steam vent in the pastry. This lets steam escape as the pie bakes, keeping the pastry crisp rather than soggy underneath.
Serving Suggestions
Serve with creamy mashed potatoes or buttered new potatoes, alongside steamed greens or buttered peas. This pie is rich and satisfying enough that it really doesn’t need much alongside it.
How to Store Delia Smith Chicken and Mushroom Pie
In the fridge: Store in an airtight container for up to 3 days. Reheat in the oven rather than the microwave to keep the pastry crisp.
At room temperature: Not suitable — cool and refrigerate promptly after cooking.
In the freezer: Freeze the assembled, unbaked pie for up to 2 months. Bake from frozen, adding extra time, or defrost fully in the fridge first before baking as normal.

Notes
Frequently Asked Questions About Delia Smith Chicken and Mushroom Pie
Why are my mushrooms watery instead of golden?
This usually means the pan was overcrowded, causing the mushrooms to steam rather than fry properly. Cook them in batches over a fairly high heat if needed, giving them room to brown.
Can I use chicken breast instead of thighs?
Yes, though thighs stay slightly more tender, particularly if there’s any risk of the pie being reheated later.
Can I make this pie ahead of time?
Yes, you can prepare the filling up to 2 days ahead and keep it covered in the fridge, then top with pastry and bake fresh when you’re ready.
Why is my pastry not rising properly?
This is almost always down to hot filling being placed under the pastry. Always let the filling cool to room temperature before topping and baking.
