Step 1

Make the soup base: In a medium bowl, combine the water, dashi stock powder, mirin, sake, soy sauce, and sugar and stir until the solids are fully dissolved.

Step 2

Make the gyudon: Pour the soup base into a large pan over medium heat, then add the sliced onion and beef. Cover, bring to a simmer, and cook for 3-5 minutes, until the beef starts to cook through.

Step 3

Uncover the pan, skim off any scum from the surface, and continue to boil for about 4 minutes, until the liquid thickens just slightly. Stir in ¼ cup of the green onions.

Step 4

Add the rice to serving bowls, then ladle in the beef and soup mixture. Top with the remaining green onions, fried garlic, onsen eggs, sesame seeds, and chili crisp.

Step 5

Enjoy!
