  • Golden and crunchy on the outside, perfectly fluffy in the middle. Our roast potatoes are sure to be the star of your roast dinner.

    Watch our video on how to roast perfect potatoes, or simply follow our step-by-step instructions below. Our method uses King Edward potatoes, shaken to fluff up the edges and roasted in sizzling hot oil. This recipe serves up to six people. It will take around 55 mins to prepare and cook, though we recommend allowing extra roasting time if the oven is crowded.



    • 1.8kg King Edward potatoes, peeled and cut into large, even-sized pieces
    • 250ml olive oil
    • Salt


    • Preheat oven to 200°C, gas 6. Place potatoes in a large pan and just cover with water. Put on the lid and bring to the boil, then simmer for 5 mins. Drain and shake in a colander to fluff up the edges.

    • Pour the oil into a large roasting tin and heat on the hob. Carefully arrange the potatoes in one layer in the tin – the oil should be so hot it sizzles when the potatoes go in. Turn them so they’re evenly coated in oil and roast for 40 mins, turning halfway through cooking.

    • Drain off the oil and season with salt. Cook for a further 5 mins.

    Top tips for making roast potatoes

    Is it necessary to parboil potatoes before roasting? 

    Parboiling is vital for that classic roast potato texture. Without parboiling, the outside of the potato won’t be able to soak in as much oil and therefore won’t get as crispy.

    How do you get crispy roast potatoes?

    To make sure your potatoes are extra crispy, get the edges really fluffy before you put them in the oven. Shake in the colander, or pop them back in the pan and put a lid on, before shaking vigorously. You could also try lightly sprinkling them in plain flour before adding to the hot oil.

    How many minutes do you par boil potatoes?

    Make sure the top of the potatoes are covered in a couple of inches of water. Bring to the boil and then simmer for 5-7 minutes. To test if a potato is done, run a fork down the side of one and see if it fluffs up.

    How long does it take to roast potatoes at 200 degrees?

    Perfectly parboiled potatoes should take about 40 minutes to cook at 200 degrees. However, a full oven will mean a longer cooking time to crisp up. If you’re cooking a full roast, allow an extra 15-20 minutes, checking regularly but being careful not to open the oven door too frequently as this will cool the temperature down.

    Which oil is best for roasting?

    Olive oil is best for vegetarians, while goose fat is a decadent classic. If you’re trying to be a bit healthier, we’d recommend swapping standard oil or goose fat for coconut oil, peanut oil and sunflower oil. 

    Why don't my roast potatoes go brown?

    Make sure your potatoes are dry once they’ve been boiled as wet potatoes won’t crisp as well. Once they are drained thoroughly, shake well to break the potatoes up slightly. You also want to make sure that the oil in the tray is hot before adding your potatoes too.

    What should I do with leftover roast potatoes?

    For delicious bubble and squeak, try them mashed up and then fried on medium heat with a couple of beaten eggs and leftover roast dinner veg tossed in.
