In a large skillet, heat over medium heat and add ground beef. Cook for 5-7 minutes until browned and no longer pink. Drain excess fat.

Add minced garlic and freshly grated ginger to the skillet. Sauté for about 1 minute until garlic is fragrant.

Stir in soy sauce, brown sugar, sesame oil, and crushed red pepper flakes. Cook for 2-3 minutes until sauce thickens slightly.

Remove from heat and stir in the white parts of the green onions.

Spoon the beef mixture over cooked rice and garnish with green onion tops and sesame seeds.
