Directions

To Prep

1. Cut and slice the onions in half and then thin lengthwise, from top to bottom (axis to axis).
2. Combine the soy sauce, sake, mirin and dashi into a bowl. Set aside.

To Cook

1. Heat the sesame oil in a large flat pan over high heat. Add the beef and cook, stirring frequently for about 2 minutes, until the beef browns slightly. Add the sugar and wait 10 seconds. Add the onion and cook, stirring constantly, for about 1 minute, until the onions begins to soften. Pour the liquid mixture into the pan. Simmer for about 5 minutes, until the ingredients cook through. While the gyudon is simmering, use a large spoon to skim off any scum and fat that appears on the surface.
2. While the ingredients are simmering, divide the rice among 4 large bowls. As soon as the gyudon is ready, spoon it over the rice and serve immediately. Season with shichimi togarashi and beni shoga, as desired.
