Mongolian Beef is a quick and easy dish, featuring tender beef cooked in a savory sauce with green onions over rice. It packs a punch of flavor and is better than takeout!
Slice the beef flank steak against the grain into thin strips.
In a bowl, combine soy sauce, brown sugar, and cornstarch to make the marinade. Add the sliced beef and let marinate for at least 10 minutes.
Heat vegetable oil in a large skillet over medium-high heat. Add minced ginger and garlic, and stir-fry for about 30 seconds until fragrant.
Add the marinated beef to the skillet, cooking until browned and cooked through, about 5-7 minutes.
Stir in chopped green onions and cook for another minute.
Serve the Mongolian Beef over cooked rice. Enjoy your meal!
