Preheat oven to 340ºF/170ºC.
Cut the potatoes into chunks. (I don't peel them)
Pour the olive oil, lemon juice, chicken stock, lemon zest, sliced garlic cloves, oregano and salt into a rimmed baking sheet and mix well to combine.
Add the potatoes into the mixture and mix gently.
Cover the roasting tin with foil and roast the potatoes for 70 minutes then remove from the oven, remove the foil and gently turn them.
Return to the oven uncovered for a further 10 minutes.
The potatoes should be soft and lightly golden and most of the liquid will have evaporated.
