Chestnut-Stuffed Mushrooms

This is a proper British holiday starter, the kind that shows up on Christmas lunch tables and works just as well on a vegetarian main course plate. Everything can be prepped hours ahead, then assembled and grilled when guests arrive.

The croûtes are the trick to keeping everything crisp. Rounds of buttered wholemeal bread bake low and slow for an hour until they are dry and golden right through, like edible saucers for the juicy mushroom and its stuffing.

Cooked chestnuts bring a sweet, earthy backbone that meat-free holiday cooking lives on. Break them up with a fork so the stuffing holds together in some spots and falls into chunks in others. That irregular texture is what keeps it from feeling like baby food.

A grate of fresh nutmeg and a squeeze of lemon at the end are doing more than you think. Nutmeg amplifies the chestnut’s sweetness, lemon cuts through the butter.

Pan-fry the mushrooms before stuffing. That initial sauté drives off their water and concentrates their savor so the final bake does not pool.

Chef Tips

• Use pre-cooked vacuum-packed or tinned chestnuts for convenience. Fresh roasted and peeled are better if you have the patience.
• Pick the largest flat-cap or portobello mushrooms you can find, and leave them gill-side-up so the stuffing has a bowl to sit in.
• The croûtes keep in a tin for several days, so make them ahead and assemble the night of.
• Swap butter for vegan margarine throughout and use wholemeal bread to keep this fully plant-based.

Variations

• Stir chopped cooked chestnuts with crumbled sage and a small grating of parmesan for a more cheesy stuffing.
• Add a tablespoon of Madeira or sherry to the stuffing for extra richness.
• Serve on polenta cakes instead of bread croûtes for a gluten-free version.
