Tip the mushrooms into a bowl, scatter over the thyme leaves and garlic powder, and season. Stir everything together to combine. Drizzle over the oil and mix again.

Preheat the air-fryer, if necessary, to 200C. Tip the mushrooms into the basket and cook for 12-15 mins, mixing up halfway through, until golden and beginning to crisp up.

A few minutes before the end of cooking, toast the bread. If you like, you can rub the toast with a garlic clove for extra flavour. Drizzle with a little oil, then spoon over the mushrooms. Scatter with parsley, if you like.
