If you're on a mission to serve roast potatoes that are golden, crunchy, and packed with flavour, there’s one game-changing yet unusual ingredient you might not expect. Although some people hate it, marmite has the ability to transform previously bland potatoes into something truly delicious. According to the Tesco Real Food team, this simple dish using Marmite melted into butter to coat parboiled floury potatoes, will make them 'crunchy and super-tasty'.

Marmite adds a rich umami flavour and a kick of savoury depth, while also helping the potatoes achieve that beautifully crisp, golden colour and texture. This suprising ingredient will add an interesting touch of savoury and almost meaty flavour to the roast potatoes, without being overpowering.

Even if you hate this divisive spread, adding just a touch of marmite will elevate your roast potatoes to the next level.

Peel and chop the floury potatoes, then place them in a large saucepan and cover with cold salted water. Cover the pan, bring to a boil, then reduce to a simmer and cook for 7 minutes, or until just tender. Drain the potatoes in a colander and let them steam dry for 10 minutes.

For 4 Maris Piper potatoes, use about 1 tablespoon of Marmite. Melt the marmite with your butter for about 2 to 3 minutes over low to medium heat, then add them to the potatoes to coat them evenly in the rich, savoury mixture.

The potatoes can then be roasted for about 20 minutes, and for longer if you've made a larger portion.

The dish is suitable for vegetarians and is perfect for a Sunday roast or any roast-worthy occasion.

While marmite should be consumed in moderation, the spreadable paste can also bring some health benefits.

According to Kerry Torrens, a registered nutritionist writing for BBC Good Food, Marmite is rich in B vitamins, especially B1, B2, B3, B6, and B12 which are essential for converting carbohydrates into energy, supporting brain function, managing stress, and aiding red blood cell production.

Its high niacin (vitamin B3) content may also help improve circulation and boost exercise performance by increasing oxygen delivery to muscles and a 2017 study even suggests that Marmite may have a calming effect due to its influence on GABA (gamma-aminobutyric acid) levels in the brain, potentially helping to ease anxiety.

However, its high percentage of salt means it is best consumed in moderation and as part of a balanced diet.
