The best crispy roasted potatoes recipe is a simple two-step affair! Steamed then roasted, your potatoes will be impossibly tender inside and shatteringly crisp outside.
Preheat your oven to 212°F/100°C, steam setting (100% humidity). If you don't have a steam oven, you can either steam in a stovetop steamer or boil your potatoes instead.
Peel your potatoes if you want to (although you certainly don't have to - I actually love a roasted potato with skin!). Depending on the size of your spuds, cut them in halves or quarters - you want each piece to be roughly 1.5-2 inches (4-5cm) in diameter.
1 lb potatoes
Put the potatoes in a single layer in a stainless steel pan or roasting dish and put the pan into your steam oven oven. Steam for 30 minutes, until they're very tender when pierced with a knife (if you're boiling instead of steaming, they will only need around 15 minutes cooking time).
Roast the potatoes
Remove the steamed potatoes from the oven and change the setting to 350°F/180°C, convection setting (no steam).
While the oven heats, drain the potatoes of any water and return them to the dish. Give them a good shake around to crush the edges slightly, this helps make them extra crispy later.
Pour the oil over the shaken-around potatoes and season with the salt. Toss to make sure the potatoes are well-coated.
1/3 cup olive oil, 1 1/2 teaspoons fine salt
Return the pan to the hot oven and roast the potatoes for 45 minutes to an hour, until they're golden, crisp and crunchy on the outside. You can give them a stir towards the end of cooking, but don't be tempted to do so until they've formed a really good crust, or you'll lose all the crunchy bits to the bottom of the pan!
If you dare, season the potatoes with extra flaky salt, then pile them into a warmed bowl and serve.

Notes
These are quite forgiving when it comes to timing. If you're making other parts of a meal and your potatoes are done too early, just lower your oven temperature to 300°F/150°C and leave them there. They'll be fine for another 20-30 minutes while the rest of the meal comes together. Or, pull them from the oven and keep them somewhere warm for up to a couple of hours. Then reheat at your roasting temperature for 10 minutes before serving.
Duck fat potatoes are a really special treat - if you can get some, use it in place of the olive oil for an amazing, savory depth of flavor.
