Heat a large skillet over medium-high heat and add the ground beef. Break it apart with a wooden spoon and cook for 5-7 minutes until fully browned with no pink remaining. Start your rice first so everything finishes at the same time.

If using beef with higher fat content, drain most of the excess fat, leaving about 1 tablespoon for flavor. Add the minced garlic and grated ginger, stirring constantly for 1-2 minutes until fragrant.

Pour in the soy sauce, brown sugar, and sesame oil, stirring well to combine. Let the mixture simmer for 3-4 minutes, allowing the sauce to reduce and coat the beef until glossy.

Add the broccoli florets if using, stirring them into the beef mixture. Cook for 4-5 minutes until the broccoli is tender-crisp and bright green.

Divide the cooked rice among serving bowls and top generously with the beef mixture. Garnish with sliced green onions and a sprinkle of sesame seeds.
