You only got 20 minutes? No problem! This easy, hearty beef bowl will not let you down. The best part of the dish is the rice that soaked up all the flavors from the beef.
In a medium pan, pour dashi broth and add sliced onion. Cook the onion over medium heat until slightly softened. About 5 minutes.
Add sake, sugar, soy sauce, salt, and beef and stir. Place a lid and cook over low-medium heat for 10 minutes.
Add graded ginger and cook for another 2 minutes.
Serve the beef over a bed of steamed rice. Enjoy!
