Step 1: In a large skillet over medium-high heat, cook the ground beef until completely browned and no longer pink, breaking it into small crumbles with a wooden spoon as it cooks.
Step 2: Drain any excess fat from the skillet. Return the pan to the heat and add the minced garlic and grated ginger. Cook for 1-2 minutes until fragrant but not browned.
Step 3: In a small bowl, whisk together the soy sauce, brown sugar, sesame oil, red pepper flakes, and black pepper.
Step 4: Pour the sauce mixture over the beef. Stir well to combine and let it simmer for 2-3 minutes until the sauce thickens and glazes the meat.
Step 5: Remove from heat. Serve the beef over hot jasmine rice and garnish with sliced green onions and sesame seeds.
