Preheat and prep: Heat the oven to 220C (200C fan) / Gas 7. Oil a baking tray.
Cut and blanch: Chop the potatoes into batons about 1cm thick. Blanch in boiling salted water for 3 to 4 minutes, then drain and spread on the prepared tray in a single layer.
Season: Drizzle with groundnut oil and toss to coat evenly. Season with smoked paprika, salt and pepper.
Bake: Roast for 15 to 20 minutes, turning now and again to ensure even cooking, until golden and crisp. Serve immediately.
