Preheat oven to 200°C. Cut the potatoes in half lengthways then each half into wedges. Place the oil, garlic salt and paprika in a large ziplock plastic bag. Add the potato wedges and seal the bag. Shake and squish the bag around so that the wedges get well coated.
Place the wedges in a single layer in an oven roasting dish. Bake for about 35 - 40 minutes. Stir them once or twice during cooking. Serve with tomato or sweet chilli sauce or for a treat try sour cream or yoghurt.
Tip: Kumara, parsnips and pumpkin can be cooked the same way. Peel them first though as their skins can be very tough.
