The katsu sando has been a phenomenon in Japan for decades but we're now seeing it all over our Instagram feeds.

Crustless sandwiches. They were all you ever wanted as a child and now, thanks to millennials being drunk on nostalgia - and Japan - they are now something you can enjoy as an adult. 

They aren't just any old crustless sandwiches, though. As good-looking as they are tasty, katsu sandos are having a moment right now. These precise and picturesque sandwiches have long been an institution in Japan, but they’re now clocking up serious capital on the world of Instagram and beyond, too.

In fact, they’re so revered as a foodie trend that TÓU, a restaurant dedicated entirely to the sando concept, will open in London this summer. 

But let’s back up a bit, in case you follow more dogs dressed like food accounts than you do food bloggers.

What exactly is a katsu sando?

Well, ‘katsu’ means cutlets and ‘sando’ is the Japanese abbreviation for 'sandwich' – so essentially it is two pieces of Japanese milk bread (shokupan) wrapped around a breaded meaty cutlet. It’s most often made from pork, but beef and chicken are sometimes also used, along with veggie versions in the form of halloumi, or Japanese omelette and katsu aubergine and slathered with a thick yet zingy sauce (tonkatsu).

The breading of the meat makes each square inch of the cutlet super crunchy. The tonkatsu sauce cuts through the richness of the cutlet and lends some depth, as well as adding a little moisture so it’s not a sad, dry sandwich. The shokupan protects the roof of your mouth from hot meat and rough breading which is a common problem people face with their everyday deli roll. It all adds up to a dish that looks as harmless and dainty as an afternoon tea sandwich but delivers all the intense meaty joy of a chicken fillet roll. 

If you’re thinking the katsu sando sort of looks similar to a schnitzel, then you’d be right. The sandwich first appeared in restaurants and cafes way back in 1899, and it was indeed, inspired by the schnitzel.

However, it is back on the food scene with a vengeance: indeed, you might say the katsu sando is the ultimate holy grail of any food-snapping Instagram user right now.

While the sandwich trend is taking over Instagram feeds quicker than lightning, it seems it's a little slower to take off in Irish restaurants, with Gertrude on Pearse Street one of the few places offering its own delectable version.
