• STEP 1

    Chop the potatoes into walnut-sized chunks and tip into a large pan of cold, salted water. Bring to the boil, then reduce the heat and simmer gently for 10 mins, or until the potatoes are cooked through and fluffy at the edges but still holding together. Drain. (Or, cook in the microwave – see tip, below.) The potatoes can be boiled the day before and chilled.

  • STEP 2

    Heat the oven to 210C/190C fan/gas 6½. Pour the oil into a large roasting tin so it covers the base – there should be a depth of about 1/2cm. Put the tin in the oven for 5 mins to heat up, then remove from the oven. Carefully tip the drained potatoes into the hot oil, and use a spatula to turn them to coat. Roast for 40 mins, then remove from the oven and turn the potatoes over using the spatula. Roast for 20 mins more, then repeat this process again for a final 20 mins until the potatoes are deeply golden and crunchy. (Or, cook in an air fryer – see tip, below.) Season to serve.

Recipe tips


To make roasties in an air fryer, peel 1kg Maris Piper potatoes and cut into walnut-sized chunks. Soak in a large pan of salted water for 1 hr. Drain and rinse, then pat dry with kitchen paper and tip into a bowl with 2 tsp vegetable oil. Toss to coat. Arrange the potatoes in a single layer in the air fryer basket (you may need to do this in batches) and cook on 180C for 20 mins. Turn or shake the potatoes, then cook for another 10 mins, still at 180C. Check the potatoes – if you want them crispier, cook for a further 10-15 mins, checking every 5 mins. If you have to cook in batches, add the previous batches together for the final 5 mins. You will get a better result if you cook in a single layer, but cooking in batches does use more energy – you can cook the potatoes in more than one layer, but you’ll need to cook them for longer to make sure they’re crisp. Keep moving them around every 10 mins to help achieve this. Remove the potatoes from the basket as soon as they’re ready so the skin doesn’t soften in the steam.


Instead of boiling the potatoes, you can microwave them. Tip the potatoes into a large heatproof bowl, pour over 100ml water, cover with a plate and microwave on high for 25-30 mins, turning occasionally  until evenly soft and fluffy. Drain well before roasting.
