Slicing against the grain ensures tender beef. Marinating with cornstarch helps tenderize the meat and create a velvet texture.
2
While the beef marinates, prepare the sauce. In a small bowl, whisk together the remaining 2 tablespoons of soy sauce, oyster sauce, 1 tablespoon of cornstarch, sesame oil, sugar, minced garlic, grated ginger, and water or beef broth until smooth.

Have your sauce ready before you start cooking, as stir-frying moves quickly.

Heat 1-2 tablespoons of vegetable oil in a large wok or skillet over high heat until shimmering. Add the marinated beef in a single layer and stir-fry for 2-3 minutes until browned and mostly cooked through. Do not overcrowd the pan; cook in batches if necessary. Remove the beef from the wok and set aside.

High heat is key for stir-frying to get a good sear on the beef and prevent it from steaming.

Add the remaining 1 tablespoon of vegetable oil to the wok. Add the sliced onions and stir-fry for 3-4 minutes until they soften and become slightly translucent and fragrant.

Cook onions until they are tender-crisp; avoid overcooking them to maintain some texture.
5
Return the cooked beef to the wok with the onions. Give the prepared sauce a quick whisk, then pour it over the beef and onions. Stir quickly to coat everything evenly. Continue to cook for 1-2 minutes, stirring constantly, until the sauce thickens to your desired consistency.
