The literal translation of Oyakodon (親子丼) means “parent-and-child rice bowl.” The typical ingredients include chicken (as in parent), egg (as in child), and onions. The ingredients are simmered together in a sauce then served on top of a bowl of rice. It’s a very common Donburi dish and served at most traditional Japanese diners.
I first learned how to cook the dish during home-making class in middle school (although this recipe is not from the textbook). It’s very easy to cook so I hope Oyakodon will be your go-to recipe when you are busy.
