Here is an easy, weeknight-friendly chicken and mushroom pie made with store-bought puff pastry. It’s creamy, hearty and quick to assemble—perfect when you don’t have time to make pastry from scratch.
After sharing a chicken and leek pie, I wanted to offer this classic chicken-and-mushroom version for anyone who loves that comforting combination of tender chicken, earthy mushrooms and a flaky pastry top.
Looking for comfort food ideas? Try this pie with a simple green salad or roasted vegetables for a balanced, satisfying meal. For a lighter alternative, you can swap in chicken breast or reduce the cream and increase stock for a less rich filling.
Ingredients
- Mushrooms: Brown mushrooms give a nuttier flavour, but white mushrooms work perfectly. For more depth, use a mix such as shiitake, oyster or flat mushrooms.
- Chicken thighs: Boneless, skinless thighs are forgiving and stay juicy. You can use chicken breast, but be aware it may be a bit drier.
- Unsalted butter: Used for richness; olive oil can be substituted if preferred.
- Plain flour: Helps thicken the sauce. You can replace with a cornstarch slurry if needed.
- Heavy cream (thickened cream): Provides a silky texture. Light cream may make the sauce looser.
Step by step instructions
This pie uses ready-made puff pastry so it’s quick to assemble yet impressively flaky when baked. The basic method is to sauté the mushrooms, onion and garlic, brown the chicken, build a simple creamy sauce, mix in peas, and transfer the filling to a pie dish. Top with just-thawed puff pastry, brush with egg wash, and bake until golden.
Key points: brown the mushrooms and chicken for flavour, thicken the sauce with flour or cornstarch, and handle the pastry while it is cold to keep it easy to work with. Bake for around 25 minutes until the pastry is puffed and golden.
Tips for making this recipe perfect every time
- Use just-thawed puff pastry. It should be defrosted but still cold. If it reaches room temperature it becomes soft and hard to lift over hot filling. Remove from the freezer about 10 minutes before you need it.
- Avoid flipping ingredients too often. To get good browning on mushrooms and chicken, leave them to sear on high heat for a minute or two before turning. This allows moisture to evaporate from mushrooms and creates a golden crust on chicken that locks in juices.
- Taste and season as you go. Adjust salt and pepper before transferring the filling to the pie dish so the finished pie is well seasoned.
- Tuck the pastry loosely. Gently tuck excess pastry into the pie rim so the edges can puff up rather than collapsing into the filling.
Good to know (FAQs)
Make a slurry with 1 tablespoon cornstarch and a quarter cup cold water, mix until smooth and stir a little at a time into the simmering sauce until it reaches your desired thickness.
A fresh green salad with a light vinaigrette or roasted vegetables such as carrots and Brussels sprouts pair well. For something heartier, oven-roasted sweet potato fries are also a great match.

📖 Recipe
Chicken and Mushroom Pie
Ingredients
- 1 sheet frozen puff pastry, just thawed
- 1 egg, whisked (for egg wash)
Pie filling
- 750 g / 1.5 lb boneless skinless chicken thighs, cut into bite-size pieces
- 300 g / 10 oz mushrooms, thickly sliced
- 1 cup frozen peas
- ½ cup chicken stock
- ½ cup heavy cream (thickened cream)
- 1 onion, finely diced
- 3 cloves garlic, minced
- 2 sprigs fresh thyme (or ½ tsp dried thyme)
- 1 tsp Dijon mustard
- 1 tbsp plain flour
- 2 tbsp unsalted butter (or olive oil)
- Salt and pepper, to taste
Instructions
- Preheat the oven to 220°C / 430°F (200°C / 390°F fan-forced).
- In a large frying pan, sauté the mushrooms with 1 tablespoon butter over medium-high heat. Cook until golden and nutty, about 7 minutes. Add the remaining butter, garlic and onions and cook for a further minute.
- Push the vegetables to the sides of the pan to make room and add the chicken. Season with salt and pepper. Seal and brown the chicken for about 2 minutes, turning once to develop colour.
- Stir through the Dijon mustard and flour, then add the chicken stock and cook, stirring, until the sauce thickens and there are no lumps of flour, about 2 minutes.
- Reduce the heat to low. Remove thyme leaves from the stems and add them along with the heavy cream. Taste and adjust seasoning.
- Turn off the heat and fold in the frozen peas so they warm through from residual heat.
- Transfer the filling to a 24cm / 8 inch round pie dish. Cover with the just-thawed puff pastry and loosely tuck the edges into the rim so they can puff up.
- Brush the pastry with egg wash and cut a small ‘X’ in the centre to allow steam to escape. Bake on the middle shelf for 25 minutes or until the pastry is golden and crisp.
Notes
Just thawed puff pastry: Puff pastry that reaches room temperature becomes soft and difficult to handle. Remove from the freezer about 10 minutes before you need it so it is defrosted but still cold to the touch.
If the sauce is too runny: Mix 1 tablespoon cornstarch with ¼ cup cold water until dissolved. Stir half of the slurry into the hot filling and it will thicken quickly; add more if needed.
Mix up the mushrooms: Using a variety of mushrooms adds complexity—try shiitake, oyster or large flat mushrooms if available.
