These grilled oyster mushrooms offer a fantastic plant-based alternative for the barbecue season. By marinating the mushrooms in a vibrant blend of fresh orange, tangy lemon and red-wine vinegar, they develop a deep, savoury profile that balances beautifully with the natural smokiness of the grill. Their meaty texture makes them a substantial addition to any alfresco spread, ensuring that vegan guests are well catered for with a dish that is both sophisticated and simple to prepare.
As a versatile vegan side dish, these mushrooms work exceptionally well alongside grilled seasonal vegetables or served as a topping for toasted sourdough. The key to success is using a perforated grill tray, which allows the heat to caramelise the edges of the mushrooms without them falling through the grate.

Ingredients for Grilled Oyster Mushrooms
2 tablespoons fresh orange juice
1 tablespoon fresh lemon juice
2 teaspoons red-wine vinegar
90ml olive oil
900g large oyster mushrooms, stems trimmed
1/2 teaspoons coarse sea salt (preferably Sicilian)
a perforated grill sheet
How to make Grilled Oyster Mushrooms
Whisk together juices, vinegar, and oil in a large bowl. Toss mushrooms with vinaigrette and marinate 15 minutes. Transfer mushrooms to another bowl with tongs, reserving vinaigrette.
Prepare grill for cooking. If using a charcoal grill, open vents on bottom of grill, then light charcoal. Charcoal fire is hot when you can hold your hand 5 inches above rack for 1 to 2 seconds. If using a gas grill, preheat burners on high, covered, 10 minutes, then reduce heat to moderately high.
Grill mushrooms in 3 batches on oiled grill sheet set on grill rack, with grill covered only if using gas grill, turning frequently, until golden brown, about 5 minutes per batch. Transfer to vinaigrette as grilled, then toss with sea salt.
