Mushroom Wellington

A soggy base almost always comes from excess moisture in the filling. Mushrooms release large amounts of liquid during cooking — cook them over high heat without crowding until all that liquid has fully evaporated. Spinach must be blanched and then squeezed as dry as possible. The filling must be completely cold before it touches the pastry — hot or warm filling starts melting the fat in the pastry and releases steam during assembly. Brushing the mushrooms with Dijon mustard creates a moisture barrier between the filling and the pastry. Finally, bake on a perforated tray or a wire rack set inside a baking sheet so that air can circulate underneath.

The best vegan egg wash substitute for colour and shine: mix 2 tablespoons of plant milk (soy or oat gives the best colour) with 1 teaspoon of maple syrup. The sugar in the syrup caramelises during baking and gives a deeper, more golden-brown finish than plain plant milk alone. Aquafaba (liquid from a can of chickpeas) is another excellent option — its protein content mimics egg white and produces a convincing gloss. Apply two coats with a 5-minute gap between them. Whatever you use, do not skip this step — the wash is also what gives the scored lines their definition.

Yes, and it's recommended. The duxelles filling can be made 2 to 3 days ahead and refrigerated. The fully assembled, uncooked Wellington keeps for up to 24 hours in the fridge, tightly wrapped — chilling it this way actually firms the pastry and helps it hold its shape going into the oven. Bake directly from the fridge, adding 5 minutes to the cooking time. The baked Wellington keeps for up to 3 days, but the pastry gradually softens. Reheat in the oven at 180°C for 15 to 20 minutes — not the microwave. To freeze: assemble uncooked, wrap tightly, freeze for up to 2 months. Thaw overnight in the fridge before baking.

A combination works best. Portobello mushrooms (4 to 5 of similar size) go in the centre — they hold their shape well, slice cleanly, and create the visual contrast you see when the Wellington is cut open. Chestnut mushrooms or cremini work best for the duxelles: they have more flavour than standard white mushrooms. Adding some shiitake to the duxelles deepens the umami further. Oyster mushrooms should be avoided — they're too delicate and collapse into mush. The key for the portobello: sear them whole until golden on both sides, drain thoroughly on paper towels, and brush with Dijon mustard while still warm.

It's one of the most reliable dishes for exactly this situation. The Wellington looks genuinely impressive — a whole golden log scored on top, brought to the table before slicing. It portions neatly, holds at temperature well, and tastes rich rather than light or 'healthy'. The combination of shattering pastry, savoury mushroom filling, and Dijon mustard is satisfying enough that meat-eaters generally don't miss anything. Serve with vegan gravy, roasted potatoes, and green vegetables, and it works as a complete centrepiece that accommodates vegans without making them feel like an afterthought.
