In a bowl, combine soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, and gochujang. Mix well to create a marinade.
Add the sliced beef to the marinade, ensuring all pieces are well-coated. Cover and marinate for at least 30 minutes or up to 2 hours in the refrigerator for better flavor.
Heat a large skillet or grill pan over medium-high heat. Cook the marinated beef in batches for 2-3 minutes on each side until well browned and cooked through. Remove from the heat.
In bowls, layer cooked rice as the base. Top with the cooked beef, then add julienned cucumber, carrot, and a serving of kimchi.
Sprinkle chopped green onions and sesame seeds on top for garnish.
Optional: Serve with lettuce leaves to wrap the beef and vegetables for a fun hand-held option.
Notes
Arrange the bowls to showcase colorful vegetables and beef. Serve with chopsticks for an authentic experience.
