A stunning vegetarian centerpiece featuring tender roasted cauliflower smothered in a rich, velvety cheese sauce and encased in golden, ruffled filo pastry. This sophisticated twist on a classic comfort dish is perfect for a cozy dinner or a festive gathering.
Preheat your oven to 210°C (190°C fan/gas 7). Place the cauliflower florets, chopped leaves, and stalks onto a large roasting tray. Toss them thoroughly with olive oil and a pinch of salt, then grate about 10g of the parmesan over the top. Roast for 30 minutes until the cauliflower is tender and the edges are lightly charred.
While the cauliflower roasts, prepare the cheese sauce. Melt 50g of butter in a medium saucepan over medium heat. Stir in the flour and cook for 2-3 minutes to create a sandy paste. Gradually whisk in the milk, a little at a time, stirring constantly to prevent lumps. Once all the milk is added, simmer for about 10 minutes until thickened. Stir in the mustard powder and most of the grated cheddar, keeping a small handful aside. Season with nutmeg, cayenne, and salt to taste.
Lightly grease a round springform cake tin with butter or oil. Lay a sheet of filo pastry inside the tin, allowing the edges to overhang. Brush the sheet with melted butter or oil and sprinkle with a little parmesan. Repeat this process with the remaining filo sheets, overlapping them to fully cover the base and sides of the tin.
Transfer the roasted cauliflower into the center of the filo-lined tin. Pour the warm cheese sauce evenly over the cauliflower. Ruffle and scrunch the overhanging filo edges inward to create a decorative border. Brush the top of the pastry with more melted butter or oil.
Scatter the remaining cheddar and parmesan over the exposed sauce in the center. Bake for 20 minutes, then carefully remove the outer ring of the springform tin (leaving the base). Bake for a further 20 minutes until the pastry is golden brown and crisp all over. Allow it to cool slightly before slicing and serving.
For the best flavor, use an extra-mature cheddar. Don't discard the cauliflower leaves; they become deliciously crispy and nutty when roasted. If the filo edges brown too quickly, loosely cover the pie with foil for the final 10 minutes of baking.
