Rosemary roast potatoes and parsnips recipe

Preheat the oven to 190C/fan170C/gas 5. Halve the potatoes. Place in a large pan of salted water. Bring to the boil and cook for 3 minutes. Add the parsnips and boil for a further 3 minutes. Drain.

Meanwhile, grind the salt and rosemary leaves in a pestle and mortar. Sprinkle on the veg.

Put the oil into the oven’s tray (that slots into the rungs of the oven) and pop in the oven for 5 minutes. Tip the vegetables into the tray, toss and roast for 1 hour. Increase the temperature to 200C/fan180C/gas 6. Turn the vegetables, then cook for 15 minutes, until golden and crispy.
