Step 1

Preheat the oven to 200C/400F (fan).

Step 2

Brush a large metal non-stick baking tray with 1 tbsp of vegetable oil. If your tray isn't non-stick, line the tray with non-stick foil instead. (*tip 1)

Step 3

Cut the potatoes into 1 cm (about 3/8 of an inch) thick slices (no need to peel).

Step 4

Sprinkle the sliced potatoes with the cornflour and transfer to the oiled baking tray.

Step 5

Sprinkle with the salt, pepper, and paprika, then drizzle on the rest of the oil (3 tbsp).

Step 6

Toss everything together with your hands so the fries are fully coated in the oil and arrange the chips in a single layer. Try to ensure they’re not touching too much.

Step 7

Cover the tray in a piece of foil that’s been greased with a little vegetable oil.

Step 8

Place in the oven for 10 minutes, then remove the foil and cook for a further 10 minutes.

Step 9

Turn the fries over using a spatula and cook for a final 5-10 minutes until golden brown and crisp.

Step 10

Transfer to a serving dish and serve.
