In a medium sized mixing bowl, whisk together the beef stock, soy sauce, brown sugar, sesame oil, garlic and ground ginger.
Lay the sliced beef to the bottom of the slow cooker and pour the sauce over top. Mix the beef slices with the sauce.
Cook on HIGH for 3 hours/LOW for 5-6 hours or until the beef is cooked through.
Take ¼ cup of the sauce out of the slow cooker and whisk together with the cornstarch. Pour back into the slow cooker and mix. Add the broccoli florets, cook on HIGH for 30 minutes or until the broccoli is tender and the sauce has thickened.
Serve over white rice and garnish with toasted sesame seeds and sliced green onions. Enjoy!
