Pre heat the oven to 200 degrees C for a fan assisted oven or 400 degrees F, or gas mark 6.
Bring a pan of salted water to the boil and cook the carrots for 4-6 minutes depending on the size until they’re just cooked. Drain well.
In a bowl, mix the carrots, parsnips with olive oil, sage, and salt. Then, lay the vegetables in a single layer in a roasting tin.
Roast in the centre of the pre heated oven for 30-35 minutes until the vegetables are tender, and begin to char.
Finish with the fresh parsley and serve.
