How to Make Mary Berry Chicken Leek and Mushroom Pie Recipe
- Preheat oven to 220C/200C fan/gas 7 or 400°F (200°C). Lightly grease a pie dish and keep the pastry chilled until needed.
- Heat the olive oil in a large frying pan and brown chicken on all sides. Remove it from the pan and set it aside while you prepare the vegetables.
- Add the butter to the same pan and sauté leeks until softened. Then cook mushrooms for 10-12 minutes until most of their moisture has evaporated.
- Melt butter if needed, then whisk in flour and cook for 2 minutes while stir continuously. This helps create a smooth base for the sauce.
- Pour in the dry white wine and reduce white wine for a few minutes. Gradually whisk in chicken stock until the sauce is smooth and lump-free.
- Stir in cream, add Dijon mustard, and add thyme. Let the sauce simmer until thick, then season to taste with salt and black pepper.
- Return chicken to the pan and stir everything together until well coated. Add the chopped parsley and cook for another 15 minutes over gentle heat if needed.
- Pour filling into pie dish and cool filling completely before adding the pastry. This helps keep the pastry crisp during baking.
- Top with puff pastry, trim the edges, and crimp edges with a fork. Brush with egg wash and cut steam vents across the top.
- Place the pie on a baking sheet and bake until golden for 30-40 minutes. Leave it to rest for a few minutes before serving.
Expert Tips For Mary Berry Chicken Leek and Mushroom Pie Recipe
Making this pie a few times has taught me that small details make a big difference. Paying attention to the filling and pastry helps create a rich, creamy pie with a crisp, golden finish every time.
- Always cool the filling before adding the pastry to help prevent soggy crust.
- I prefer chicken thighs stay tender during baking, and they are usually more flavorful than chicken breasts.
- Do not skip white wine if possible, as it adds excellent depth of flavor to the creamy sauce.
- Balance the cream with enough mustard and herbs so the filling stays rich without feeling too heavy.
- Taste the filling and season to taste before it goes into the pie dish because the pastry cannot be seasoned later.
- Cook the sauce until you have a thick creamy sauce so it does not become runny while baking.
- For the best finish, brush with egg wash evenly to create a shiny golden puff pastry.
- Remember to cut steam vents in the pastry so steam can escape without cracking the top.
- If you have extra cooked chicken, use leftover roast chicken for a quick variation, and chill filling before assembling for even better pastry results.
- If you have extra pastry, decorate pastry with trimmings to give the pie a classic homemade look.

FAQs
Can I use chicken breasts instead of chicken thighs?
Yes. Chicken breasts work well and make a slightly leaner pie. Be careful not to overcook them so the meat stays tender.
Can I make this pie ahead of time?
Yes. You can prepare the filling a day in advance and keep it chilled. Assemble the pie before baking for the best pastry texture.
Can I freeze the pie?
Yes. You can freeze the baked or unbaked pie for up to 3 months. Defrost it in the refrigerator before baking or reheating.
Why is my pastry soggy?
A warm filling is the most common cause. Always let the filling cool completely before adding the pastry and baking.
How do I reheat leftovers?
The oven gives the best results because it helps keep the pastry crisp. Heat until the filling is thoroughly hot before serving.
Can I replace the white wine?
Yes. Replace it with extra chicken stock if you prefer not to cook with wine. The flavour will still be delicious, although slightly milder.
What can I serve with this pie?
Mashed potatoes, buttered peas, steamed cabbage, or a fresh green salad all pair well with the creamy filling. Crusty bread is also great for enjoying the extra sauce.
Can I use leftover roast chicken?
Absolutely. Leftover roast chicken is a great time-saving option. Simply stir it into the finished sauce and avoid overcooking it.
