Smash the garlic in mortar & pester; if no mortar & pester available, chopped finely.
Cut Ribeye steak into cubes.
Marinate beef with garlic, brown sugar, light soy sauce and oyster sauce for at least 1 hour.
Pre-heat wok to high heat and then add oil.
Add beef cubes and sear on all sides by shaking your wok – therefore the name “shaking beef”. Cook on high-heat for 4-5 minutes which is about medium to medium-rare.
TIP: if you are cooking more than 1 lbs of beef, don’t cook more than 1 lbs. of beef at a time. Crowding the wok won’t give your beef enough “room” and it won’t have a nice sear and char on the outside.
Serve with steamed rice.
