Crispy roast potatoes

1.Preheat oven to 200°C or 180°C fan. Line a large baking tray with baking paper.

2.Cut potatoes in half or quarters, depending on size. Place in a medium saucepan and add enough water to cover. Boil 5-7 minutes, until just tender. Drain and cool slightly. With lid on, shake pan gently so potato becomes slightly rough on surface.

3.Place potatoes, oil and rosemary, if using, in a large bowl. Season well and toss to coat. Place potato in a single layer on prepared tray and bake 30 minutes. Turn potato and add garlic, if using, to pan. Bake another 30 minutes, until very crisp. Serve immediately.
