what gas mark for roast potatoes

For classic crispy roast potatoes, use about Gas Mark 6–7.

Best gas mark

• Most traditional recipes recommend roasting potatoes at Gas Mark 6 (200°C / 400°F) for a good balance of fluffy inside and crisp outside.

• If you like them extra crunchy , you can go up to Gas Mark 7 (220°C / 425°F) and keep an eye on them so they do not burn.

Simple timing guide

• At Gas Mark 6 : roast parboiled potatoes for roughly 40–60 minutes , turning once or twice until golden.

• At Gas Mark 7 : they will brown faster, so start checking after about 35–40 minutes.

Quick prep tips

• Parboil potatoes briefly, then drain and rough up the edges in the pan for extra crisp results.

• Preheat the fat in the roasting tin so the potatoes sizzle when they go in, and avoid crowding the tray so they can brown properly.

TL;DR: Set your oven to Gas Mark 6 for standard roast potatoes, or Gas Mark 7 if you want them extra crispy and are watching them closely.
