Beef Rice Bowl (Gyudon)

Thinly slice the beef (shabu-shabu style) and the onions.

Bring dashi, soy sauce, mirin, and sugar to a boil in a pot.

Add the onions and simmer until they are soft and translucent.

Add the beef slices to the pot and cook until just browned.

Skim off any foam that rises to the surface for a clear sauce.

Fill a bowl with rice and top with the beef and onion mixture along with plenty of the liquid.
