Gyu-Don, or beef bowl, is one of the most popular rice bowl dishes in Japan. It’s basically soy-flavored and slightly sweet simmered thin beef slices over rice. Here in LA where I live now, unless I take a trip to a Japanese market, I can’t get very thinly sliced beef at a regular market like in Japan. So, I usually get a block of boneless beef short rib and hand-slice it very thinly myself. I actually find this hand-cut version better than the other. The meat is simmered with onion in donabe for about half an hour and the result is such tender and flavorful beef. Donabe can bring out all the umami flavors cooked in it and become quite magical.
