  • 1 large sweet potato (roughly 500g / 1lb) chopped into 1cm / ½inch cubes
  • 2 tablespoons olive oil
  • Salt and pepper to taste
  • 3 sprigs rosemary leaves only, chopped finely
  • 3 cloves garlic crushed or grated


  1. Preheat your oven to 220C / 200C fan / gas mark 7 / 425F.

  2. Place the sweet potato cubes on a large non-stick baking tray, drizzle over the olive oil and sprinkle with plenty of salt and pepper.
  3. Turn the sweet potato cubes to coat them evenly in the oil, then ensure the cubes are well spread out (use 2 baking sheets if necessary) and in a single layer. Roast in the oven for 15 minutes.
  4. Remove from the oven, sprinkle over with the garlic and rosemary. Turn the cubes to get them all coated in the rosemary and garlic. Return to the oven for a further 10 minutes.

  5. Serve as part of a roast dinner or with burgers, chicken, fish or anything you usually serve with chips (fries)!


  1. It’s super important to ensure the sweet potato cubes are spread out well over the baking sheet - if they are touching each other too much or piled on top of each other they will steam rather than roast… which won’t taste anything like as nice!
  2. Suitable for freezing
