Heat the oven to 200C/180C fan/gas 6. Bring a large pan of lightly salted water to the boil. Cut the potatoes into chunky wedges, then boil in the water for 7 mins. Drain and leave to steam dry for 5 mins.
Spread the wedges out on a large baking sheet or two smaller ones. Toss with the oil and 1 tsp salt (preferably sea salt) and spread out so that they aren’t overlapping. Roast for 30 mins, turning halfway until golden and crisp.
Add paprika or cheeseAdd 2 tsp hot smoked paprika for added spice or make them cheesy by sprinkling 100g grated cheddar over the wedges 5 mins before the end of the cooking time.
