01 - Rinse rice under cold water until water runs clear. Combine rice and 2 cups water in a saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 12–15 minutes until rice is tender and liquid is absorbed. Fluff with a fork before serving.
02 - Whisk together soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, gochujang, and rice vinegar in a small bowl until sugar dissolves and mixture is well combined.
03 - Heat a large skillet over medium-high heat. Add ground beef and cook, breaking up with a spatula, until browned throughout, approximately 5 minutes. Drain excess fat if desired.
04 - Pour the prepared sauce over the browned beef. Cook, stirring constantly, for 2–3 minutes until beef is evenly coated and sauce thickens slightly.
05 - Divide steamed rice among 4 bowls. Top each portion with beef mixture, julienned carrots, sliced cucumber, scallions, and sesame seeds. Add kimchi and cilantro if desired. Serve immediately.
