Who doesn’t love roast potatoes?

They’re a British institution – whether on a Sunday dinner, as a side or cheeky snack.

But, while the crispy, golden carbs may seem simple, it’s all too easy to get them wrong.

Nobody enjoys a greasy, or undercooked spud.

Luckily, there are a number of ways to ensure you get that satisfying crunch and colour.

One social media cook has shared his clever trick for ensuring his roasties come out perfect overtime.

What's your favourite way of cooking roast potatoes? let us know in the comments section...

Use 3lb of Russet potatoes
Toss the parboiled spuds in oil and rosemary salt

Sonny Hurrell, who has 3.1 million followers on TikTok, @thatdudecancook, posted a video with his failsafe recipe.

The clip racked up a whopping 546k views.

He claims that the hack will “change the way you make roast potatoes for the rest of your life.”

Firstly, Sonny recommends washing and peeling your spuds before chopping them.

He said: “Cut them how you want, just make sure they’re all the same size.”

Throw the potatoes in the hot pan

The cook uses 3lb of Russet potatoes for his recipe.

He added: “Bring some water to a boil and add a quarter cup of Kosher salt.

“Then add a teaspoon of baking soda – that’s the trick!”

You don’t need to use Kosher salt, you can use regular salt, but Kosher is recommended as it doesn’t have any additives.

Sonny continued: “Cook your potatoes for 20-25 minutes until almost fork tender.”

He then says to preheat your roasting tray in the bottom of an oven which is preheated to 180 degrees celsius in a fan oven.

Drain your spuds, add a little oil and some rosemary salt.

After he tosses the potatoes a little to coat them in the oil and salt.

Look at those crunchy, crispy potatoes

So, how does the baking soda affect the potatoes?

Sonny said: “The baking soda breaks down the edge of the potatoes which results in the best crunch possible!”

Add some more olive oil to your hot roasting tray, pour in the potatoes and roast them for 35 to 40 minutes.

Make sure you turn them periodically so that they get a good, even crust.

Serve with salt and pepper… and gravy if you’re a true Brit.

This trick is super economical – you can pick up a pot of baking soda for just £1.25 per 180g.

A teaspoon is about 4g, so it'll set you back just 2p a pop.

We can’t wait to give this hack a try.

Perfect roasties… here we come.
