Once the water is boiling add the potatoes and parboil the potatoes for 10 minutes.

Once the potatoes have parboiled take them out and drain in a colander. Shake the potatoes in the colander to rough them up

Roast for 20 minutes then carefully flip the potatoes, let cook another 15 then rotate again and repeat one-two more times.
