In a large skillet over medium heat, cook the ground beef until browned, about 5-7 minutes. Drain excess fat if necessary.
Add soy sauce, sesame oil, brown sugar, garlic, and ginger to the skillet. Stir well and cook for another 2-3 minutes until the beef is well coated and heated through. Remove from heat.
In serving bowls, layer 1 cup of cooked rice as the base.
Arrange the cooked beef on top of the rice, followed by the blanched spinach, carrots, cucumber, and bean sprouts in sections around the bowl.
Top each bowl with a fried egg, sprinkle with sesame seeds and sliced green onions.
Serve with gochujang on the side for those who want a spicy kick.
