Start by preheating the oven to 200℃ (or 180 if you have a fan oven). Grab a roasting tray and put it in the oven to warm up.

While that's getting nice and toasty, we also need to get a pan of water heating up on the stove. You'll need quite a bit one.

Then we need to start the potatoes. You need to peel off the skins and use a knife to cut them into chunks. For a normal sized potato, you'll probably be able to cut it into 4 good sized pieces. Once the water is boiling, put the potatoes in and leave them to cook for around 10 minutes. They should be almost fully cooked. Drain the water and set aside.

Remember that tray in the oven? We need to add the oil. You're going to need quite a lot, to make a layer on the bottom on the pan. Probably about 100ml if you want to measure. Once you've poured in the oil, it needs to back in the oven so the oil gets nice and hot.

And then, we're ready to (very carefully) add the potatoes to the tray. They should sizzle when you put them in the oil. Then back into the oven for total of 45 minutes, remembering to give them a little mix around every 15 mins.

Once they're done, they should be golden and crispy. Sprinkle some salt and pepper on top, and that's it. Enjoy some amazing roast potatoes!
