In a skillet over medium-high heat, cook the ground beef until well-browned and no longer pink, about 7 minutes. It will naturally release some fat, so just spoon out or drain the excess liquid using a strainer if needed.
1 pound ground beef
Meanwhile, steam the broccoli florets in a steamer basket over boiling water in a pot for approximately 4 minutes.
3 cups broccoli florets
Add cornstarch to the beef. Stir and cook until it turns crispy, about 3 minutes.
1 tablespoon cornstarch
In a small bowl, stir together the soy sauce, brown sugar, garlic cloves, sesame oil, and gochujang until sugar is dissolved. Pour this soy sauce mixture over the beef and stir to combine. Cook for 2 minutes.
¼ cup soy sauce or tamari, ¼ cup brown sugar, 4 garlic cloves, 2 teaspoons sesame oil, 1 tablespoon Gochujang
Add the broccoli, stir, and continue to cook 2-3 more minutes. Serve over rice and garnish with sesame seeds.
