How to make tonkatsu: Japan's ultimate crispy pork cutlet

Tonkatsu is breaded, fried pork at its most refined. The Japanese version differs from Viennese schnitzel or Italian cotoletta in one significant way: panko breadcrumbs. These large, airy, irregular crumbs absorb less oil than standard breadcrumbs and produce a crust that is audibly crispy - the kind of shatter that signals something is properly fried. Paired with shredded raw cabbage, tonkatsu sauce and a smear of Japanese mustard, tonkatsu is a meal that tastes considerably more involved than it is.

The pork: cut and thickness

Pork loin (rosu) is the most common cut. It has a strip of fat along one edge that renders during frying and adds flavour to the surrounding meat. Cut it into pieces about 1.5 to 2 centimetres thick. Score the fat edge at 1cm intervals before coating - this prevents the fat from contracting during frying and causing the cutlet to curl. Season with salt and pepper on both sides.

Pork tenderloin (hire) is an alternative: softer, leaner and more prone to drying out if cooked a minute too long. It is traditionally cut thicker - about 3 centimetres - and fried at a slightly lower temperature to ensure the centre reaches the correct internal temperature without the exterior burning.

The three-stage coating

Flour, then beaten egg, then panko. Each stage serves a specific purpose. The flour creates a dry, rough surface for the egg to adhere to. The egg binds the panko. The panko provides the crumbs and, during frying, the air pockets between them expand and create the characteristic shattering crust. Press the panko firmly into the meat on all surfaces - any area that is not covered will not crisp.

Frying

Fill a heavy deep pot with enough neutral oil to fully submerge the cutlet - a minimum of 4cm of oil. Heat to 170 degrees Celsius. Lower the cutlet in slowly from the edge - never drop it in, as the impact spreads oil. Fry for 4 minutes on the first side, then flip carefully and fry for another 3 to 4 minutes. The internal temperature should reach 65 degrees Celsius. Lift out and rest on a wire rack for 2 minutes before slicing. Cut into 1.5cm strips with a sharp knife.

Serving

Tonkatsu must be served immediately after cutting. The crust softens quickly once sliced. Arrange on a plate alongside finely shredded cabbage, a generous drizzle of tonkatsu sauce and Japanese mustard. Explore our tonkatsu tools collection.
