In a large skillet, heat the sesame oil over medium heat until it begins to shimmer slightly.
Add the minced garlic and grated ginger to the skillet. Sauté for about 30 seconds, stirring frequently, until fragrant but not browned.
Increase the heat to medium-high. Add the ground beef, using a wooden spoon to break it into smaller pieces. Cook until the beef is browned and no longer pink, which will take about 5-7 minutes. Ensure to stir occasionally for even cooking.
In a separate bowl, whisk together soy sauce, gochujang, brown sugar, and rice vinegar until the mixture is smooth and well combined. Pour this flavorful sauce over the cooked beef in the skillet, stirring thoroughly to coat the meat evenly.
Add the broccoli florets and julienned carrots to the skillet. Cook for an additional 5 minutes, stirring occasionally, until the vegetables are tender yet still retain a vibrant color and a slight crunch.
Remove the skillet from heat and fold in the sliced green onions, making sure they are evenly distributed throughout the beef mixture. Reserve a small handful of green onions for garnish.
To serve, spoon the spicy beef and vegetable mixture generously over individual scoops of warm cooked rice. Finish by sprinkling with sesame seeds and the reserved green onions for a pop of freshness.
Notes
Adjust the level of gochujang to control the spiciness.
