Preheat the oven and the dish you plan to roast the potatoes in to 220 degrees C.
Combine the salt, thyme, rosemary and pepper.
In a bowl add the peeled potatoes, drizzle with about a tablespoon of olive oil, sprinkle with half the the herb mix, then toss. Repeat with another tablespoon of olive oil and the remained of the herb mix.
Remove the dish from the oven then tip in the oil and herb covered potatoes. Cook for 20 minutes.
Remove and turn the potatoes, return to the oven and reduce the temperature to 180 degrees C. Cook for an additional 40 minutes, time may vary based on size and type of potato.
