An overhead shot of the golden-brown Mushroom Phyllo Pie, with its characteristic crinkled top layers revealing hints of the filling beneath. The pie is photographed on a rustic wooden board with soft natural lighting highlighting the flaky, buttery texture of the phyllo. A slice has been removed, exposing layers of mushroom filling with steam gently rising, suggesting it's freshly baked. Scattered around the board are fresh thyme sprigs, whole mushrooms, and crumbled feta, hinting at the key ingredients. A light dusting of flour adds authenticity to the scene, while the rich browns and creams of the pie contrast beautifully with the earthy tones of the mushrooms and the bright green herbs.

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (350°F). Lightly brush your pie dish with a small amount of the melted butter to prevent sticking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Heat the olive oil in a large sauté pan over medium heat. Add the onion and cook for 5-7 minutes until soft and translucent but not browned. Add the garlic and cook for another minute until fragrant.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Increase the heat to medium-high and add the mushrooms in batches (overcrowding will cause them to steam rather than brown). Allow each batch to cook until golden brown before adding more - this caramelization is crucial for developing rich flavor. Continue until all mushrooms are cooked, about 10-12 minutes total.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the thyme and rosemary to the mushrooms, stirring to combine. Pour in the white wine (or stock) and let it bubble away, scraping up any browned bits from the bottom of the pan. This deglazing process captures all the concentrated umami flavors.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Add the spinach and cook until just wilted, about 1-2 minutes. Remove the pan from heat and let the mixture cool for about 10 minutes. The cooling prevents the eggs from scrambling when added to the filling.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>In a large bowl, combine the feta, ricotta, beaten eggs, Parmesan, salt, pepper, and nutmeg. Fold in the cooled mushroom mixture until everything is well incorporated.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Working quickly (as phyllo dries out fast), lay one sheet of phyllo in your prepared dish, allowing the edges to hang over the sides. Brush lightly with melted butter. Phyllo is delicate, so don't worry if it tears slightly – the layers will hide any imperfections.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Rotate the dish slightly and place another sheet of phyllo, overlapping the first. Brush with butter again. Continue with 4 more sheets in total, rotating the dish each time to create a star pattern, and buttering between each layer. These overlapping sheets create the beautiful flaky texture.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Pour the mushroom and cheese filling into the phyllo-lined dish, spreading it evenly. Fold the overhanging phyllo edges over the filling, brushing with butter as you go.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Take the remaining 2 sheets of phyllo, crumple them slightly (this creates more surface area for a beautiful presentation), and place them on top of the pie. Brush generously with the remaining butter and sprinkle with sesame seeds if using.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Bake in the preheated oven for 35-40 minutes, until the phyllo is golden brown and crisp, and the filling is set. If the top begins to brown too quickly, loosely cover with foil.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Remove from the oven and let the pie rest for 10-15 minutes before slicing. This resting period allows the filling to set completely, making it easier to get clean slices. Serve warm or at room temperature, perhaps with a simple green salad on the side.</li></ol>

Chef’s Notes

A few helpful details for making this recipe.

Can I prepare phyllo pastry dishes ahead of time?

You can prepare the mushroom filling 1-2 days ahead and store it refrigerated. However, it's best to assemble the phyllo layers just before baking, as the pastry dries out quickly. Alternatively, you can fully bake the pie, refrigerate, and reheat at 160°C until warmed through.

What's the best way to prevent phyllo pastry from drying out while working with it?

Keep unused phyllo sheets covered with a slightly damp tea towel while working. Work quickly but carefully, and have your melted butter and brush ready before unwrapping the pastry. Don't worry about small tears—the multiple layers will hide any imperfections in the final baked dish.

Which mushrooms create the richest flavour in a vegetarian pie?

A mixture of mushroom varieties creates the most complex flavour profile. Portobellos provide meatiness, shiitakes contribute earthiness and umami, while cremini (baby bellas) offer a balanced flavour. Wild mushrooms like chanterelles or porcini can elevate the dish further with their distinct tastes.
