Jamie Oliver

'I've discovered that the humble potato masher is the secret to the perfect roastie,' says Jamie. He recommends using Maris Piper potatoes, peeled and cut into even chucks – 'twice the size of a squash ball is about right,' he advises.

Remove the starch by washing the peeled potatoes, then pop in a pot of water, season generously and bring to the boil. Cook for 6 to 7 minutes, drain, then shake up in the colander so they'll fluff up nicely in the oven.

Jamie recommends cooking your potatoes for 30 mins at 190ºC/375ºF/gas 5 in your chosen fat – for 1.5kg of potatoes, try a good couple of lugs of olive oil, or 50g butter, diced, or 2 tablespoons of goose fat. Take out of the oven and then... 'Now's the time for my new trick. Gently squash each potato with a potato masher to increase the surface area – the more of your potato that's in contact with the pan, the crispier it will be.'

Pop back in the oven and then cook for a further 40 mins. Before you do so, you could add extra flavour with a mix of red wine, oil, seasoning and herbs – you can see Jamie's favourite roast potato combos here (opens in new tab).

Mary Berry

'If you know you’re going to be pushed on Christmas Day, then half-roast the potatoes the day before,' says Mary, who, like Jamie, is a fan of using Maris Pipers. 'On Christmas Day they just need to be re-roasted in a hot oven for about 20 minutes.'

James Martin

'Don’t try to roast your potatoes at the same time as your turkey,' warns James Martin. 'The turkey creates too much steam in the oven and your potatoes won’t roast. Take the turkey out and wrap it, then put the potatoes in.'

The Hairy Bikers

'Nothing beats perfect roast potatoes,' say the Hairy Bikers (opens in new tab). 'It makes all the difference to your Christmas lunch.' they have a recipes that guarantees spuds that are soft on the inside and super crunchy on the outside.

Like Jamie, they peel and then parboil their potatoes for a few minutes, then drain and shake in a colander to roughen the edges.

But their trick is to sprinkle with 2tbsps of polenta, plus salt and pepper.

They also recommend you pour the potatoes into a tin where the fat is already 'sizzling' hot. 'Goose fat is a must to make the tastiest, crispiest roasties ever,' they say. The oven should be set to 220C and the recommended cooking time is 45 minutes.
