Ingredients Breakdown
Choosing the Best Mushrooms
A variety of mushrooms adds depth to the filling, creating a complex and well-balanced flavor. Field mushrooms offer a meaty texture, while button mushrooms contribute a mild, delicate taste. Swiss brown mushrooms provide a deeper, nuttier essence, and portobello mushrooms bring an intense umami punch. Combining these varieties ensures a rich and satisfying filling.
The Importance of Aromatics
Onion, garlic, and thyme form the backbone of the dish’s flavor. The red onion caramelizes as it cooks, infusing the filling with sweetness. Garlic enhances the savoriness, while thyme adds an herbaceous touch that pairs beautifully with the mushrooms.
Building the Creamy Base
A combination of white wine, flour, and thickened cream creates a luxurious sauce that binds the filling together. The wine deglazes the pan, extracting the deep, concentrated flavors from the sautéed mushrooms. Flour acts as a thickening agent, ensuring the mixture has a smooth, velvety consistency. The addition of cream adds richness, balancing the earthy flavors of the mushrooms.
The Pastry Component
Butter puff pastry is essential for achieving a light, crisp crust that encases the filling beautifully. Its flaky layers contrast with the creamy mushroom mixture, providing a perfect texture combination. Choosing a high-quality puff pastry ensures a buttery, golden result.
Step-by-Step Instructions
Preparing and Sautéing the Mushrooms
To maximize flavor, the mushrooms must be cooked in batches to allow proper browning. Cooking them over high heat ensures their moisture evaporates, intensifying their natural taste. Each batch is transferred to a separate bowl, allowing the flavors to develop independently before being combined.
Cooking the Aromatics and Wine Reduction
Once the mushrooms are set aside, butter is melted in the same pan to sauté the red onion until it becomes soft and golden. White wine is then added, reducing over a few minutes to enhance the dish’s complexity and impart a slight acidity that balances the richness of the filling.
Thickening the Sauce
Flour is incorporated into the onion mixture, forming a roux that thickens the sauce. Stirring continuously prevents lumps from forming, ensuring a smooth consistency. Thickened cream and crushed garlic are added next, creating a silky, aromatic base that coats the mushrooms evenly.
Assembling the Pie
The puff pastry is carefully placed over the filling, ensuring a snug fit. Trimming excess dough prevents uneven baking, while small incisions allow steam to escape, keeping the crust crisp. A light brushing of cream adds a golden sheen to the finished pie.
Baking and Final Touches
The pie is baked until the pastry is deeply golden and puffed, signaling its readiness. A baking tray placed on a lower rack catches any potential drips, preventing a messy oven. After baking, the pie rests briefly before serving, allowing the flavors to meld.
Recipe Tips & Frequently Asked Questions
How to properly clean and slice mushrooms for even cooking – Wipe mushrooms clean with a damp cloth instead of rinsing to prevent excess moisture. Slice them evenly for uniform cooking.
The best way to prevent the pastry from becoming soggy – Ensure the mushroom mixture is thick and not overly watery before adding the pastry. Baking at the correct temperature also helps achieve a crisp crust.
Tips for making the filling in advance for easier preparation – The mushroom filling can be prepared a day ahead and stored in the refrigerator. Allow it to come to room temperature before assembling the pie.
Adjusting seasoning to enhance the umami depth of the mushrooms – Season generously with salt and black pepper, and consider adding a splash of soy sauce or a sprinkle of parmesan for extra richness.
Can I use other mushroom varieties, like shiitake or cremini? – Absolutely! Different mushrooms bring unique flavors and textures, so feel free to experiment.
How do I keep the puff pastry crisp when baking? – Brush the top with cream, avoid overfilling, and ensure the oven is preheated for optimal puffing.
Can I make this pie ahead of time and reheat it later? – Yes, reheat in an oven at 180°C (350°F) until warmed through to maintain crispness.
What’s the best way to store leftovers? – Store in an airtight container in the fridge for up to three days. Reheat in the oven rather than the microwave to preserve texture.
Can I make this recipe vegetarian-friendly with dairy-free alternatives? – Use a dairy-free butter substitute, coconut cream, or cashew cream to replace thickened cream for a fully plant-based version.
What to Serve With This Recipe
Fresh and Bitter Greens – Radicchio, arugula, or mixed greens provide a refreshing contrast to the pie’s richness.
Hearty Complements – Roasted root vegetables, steamed asparagus, or sautéed green beans pair beautifully.
Wine Pairing Suggestions – A crisp white wine like Sauvignon Blanc or a light red like Pinot Noir complements the dish’s earthy flavors.
Bread Pairings – A crusty baguette or sourdough is perfect for soaking up the creamy mushroom filling.
Variations and Customization
Adding cheese to the filling for extra richness – A sprinkle of gruyère or parmesan enhances the depth of flavor.
Using a shortcrust pastry for a more traditional pie texture – For a sturdier crust, swap puff pastry for shortcrust pastry.
Incorporating different herbs and spices for a unique twist – Add rosemary, sage, or a pinch of nutmeg to enhance the seasoning.
Making individual mushroom pies instead of a large one – Use small ramekins to create personal-sized portions for an elegant presentation.

Ingredients
1/2 cup (125ml) extra virgin olive oil
50g butter, chopped
1 large red onion, sliced
2 garlic cloves, crushed
1/2 cup (125ml) white wine
1/3 cup thyme leaves, plus 4 extra sprigs
1 tbs plain flour
300ml thickened cream
300g field mushrooms, thickly sliced
250g large button mushrooms, thickly sliced
200g Swiss brown mushrooms
225g portobello mushrooms
375g sheet frozen butter puff pastry, thawed (we used Carême)
Radicchio leaves, to serve (optional)
Instructions
Preheat the oven to 200°C (180°C fan-forced). Heat a large, deep cast-iron skillet over high heat. Pour in 2 tablespoons of olive oil and add the field mushrooms. Cook for about 5 minutes, stirring frequently, until they develop a golden color and their liquid has fully evaporated. Transfer them to a heatproof bowl. Repeat this process with the button and Swiss brown mushrooms, adding another 2 tablespoons of oil and cooking for 5 minutes until golden and dry. Transfer to the bowl.
For the final batch, heat the remaining oil in the skillet and add the portobello mushrooms. Cook for another 5 minutes, stirring occasionally, until they turn golden and their moisture has cooked off. Once done, transfer them to the bowl with the other mushrooms and set aside.
Reduce the heat to medium and melt the butter in the same pan. Add the sliced red onion and stir continuously for about 2 minutes, allowing it to soften and develop a light golden hue. Pour in the white wine, followed by most of the thyme leaves and the extra sprigs. Let the mixture simmer gently for about 3 minutes, stirring occasionally, until the wine reduces by two-thirds.
Sprinkle in the flour, stirring constantly for 1 minute to remove any raw taste. Gradually pour in the thickened cream, reserving 2 teaspoons for later, then add the crushed garlic. Return all the cooked mushrooms, along with any juices that have collected in the bowl, back into the pan. Stir well to combine everything, bringing the mixture to a gentle simmer before removing it from the heat. Generously season with salt flakes and freshly ground black pepper—mushrooms can handle bold seasoning.
Lay the puff pastry over the mushroom filling, trimming away any excess. Prick a few small holes in the pastry using the tip of a knife to allow steam to escape. Lightly brush the surface with the reserved 2 teaspoons of cream for a golden finish.
Place the skillet in the preheated oven. To prevent spills, position a large baking tray on a lower rack to catch any sauce that may bubble over. Bake for 35 to 40 minutes, or until the pastry is golden brown, puffed, and crisp. Once baked, remove from the oven and let it rest for 5 minutes before serving.
Garnish with the reserved thyme leaves and serve with radicchio leaves on the side, if desired.
