Preheat the oven to 200°C/180°C fan oven/Gas Mark 6. Put the mushrooms into a greased roasting tin, scatter over the garlic, arrange a sprig of cherry tomatoes - still on the vine - on top of each mushroom, then drizzle with olive oil.

Season well with salt and freshly ground black pepper, then cover with foil and bake for 15 minutes.

Take the foil off the mushrooms and continue to roast, uncovered, for a further 15 minutes.
