Preheat the oven to 475°F/250°C or Gas mark 9.
Wash and dry the potatoes and rub them with some vegetable oil.
Arrange the potatoes on a roasting tray and place in the heated oven for approximately one hour. Test with a thin knife and remove from the oven when soft.
Wash and slice the spring onions.
Melt 25g of butter in a saucepan, add the onions and sprinkle with a little salt.
Cook gently until the onions are soft, and then remove from the heat.
Halve the potatoes lengthways, and remove the flesh with a spoon, being careful not to break the skin.
Crush the potatoes with a fork; add the remaining butter, milk, salt, pepper and spring onions.
Finally, spoon the potato mixture back into the potato skins, sprinkle with grated parmesan and place onto a baking tray to brown under a hot grill.
Serve and enjoy.
