  1. Preheat the oven to gas 6, 200°C, fan 180°C.
  2. Peel the potatoes and cut in halves, or quarters if they’re big. Keep your peels, if using as suggested in the tip, below.
  3. Put the potatoes in a large saucepan of water and bring to the boil. Simmer for 10-12 mins until just tender. Drain well and give them a shake in the pan to rough up the sides, then spoon into a baking tray or baking dish. Set aside for 2 mins so they can let off excess steam.
  4. Drizzle over 100ml oil, toss well and roast in the oven for 25 mins.
  5. Remove the potatoes from the oven and turn to brown evenly. Add the red onion slices and the remaining oil.
  6. Return to the oven and cook for another 20-30 mins. For the last 10 mins, add the sage leaves. Cook until the sage leaves are crispy, and the red onions are meltingly tender.

Tip: Roast your potato peels in a few tablespoons of Crisp ‘n Dry 100% rapeseed oil for 10-15 mins until crispy and golden. Serve alongside the roast potatoes or on their own.
