Preheat oven to 180°C.

Step 2

Place mushrooms on an oiled oven tray. Drizzle with oil and vinegar; sprinkle with garlic and tarragon, season.

Step 3

Roast in oven for 10 minutes, then cover with foil and roast for a further 5 minutes or until tender. Remove mushrooms from oven; set aside to cool slightly, then halve.
