Chop the scallions, thaw out the ground beef, and soak the rice cakes in water.
In medium heat, saute the scallions and ground beef together, and season with a bit of soy sauce, salt, and pepper.
Saute until the beef is slightly browned and fragrant, then remove from the pan, leaving the oil.
Using the same pan, place it on low heat, add more oil, then fry the rice cakes until they’re crispy on the outside.
Once rice cakes are blistered and slightly browned, season with soy sauce, sugar, and garlic, then mix well until they are coated with the sauce.
Add back the ground beef mixture and mix to combine. Saute until the sauce has caramelized.
Turn off the heat, then add gochugaru, sesame oil, and sesame seeds.
