Steak don (ステーキ丼) is a Japanese rice bowl topped with seared, sliced steak and a punchy garlic soy sauce. It's a lunchtime favourite at Japanese steak restaurants and has become a viral favourite online.
The method is simple: crisp thinly sliced garlic in oil, sear the steak in that garlic oil, then make a quick pan sauce with butter, soy sauce and mirin.
Rest the steak before slicing so the juices stay inside, then pour any that collect over the rice.
