This Chinese-style steak stir-fry pairs seared beef with tender bok choy and a glossy savory sauce. It is fast, deeply flavorful, and perfect for serving over steamed rice on a busy weeknight.
Cut the steak into 1-inch cubes, leaving a little fat attached for better flavor. In a medium bowl, toss the beef with 1 tbsp vegetable oil, baking soda, cornstarch, and salt until evenly coated. Let stand for 30 to 60 minutes.
In a small bowl, whisk together the water, ketchup, Worcestershire sauce, soy sauce, oyster sauce, white pepper, and sesame oil. Set the sauce aside.
Trim and separate the bok choy leaves, then wash them very well to remove any grit. Drain thoroughly so the vegetables stir-fry instead of steam.
Heat a wok or large skillet over high heat. Add 1 tbsp vegetable oil, then immediately add the ginger slices. After a few seconds, add the garlic and bok choy.
Stir-fry the bok choy quickly until it just starts to wilt, about 1 minute. If needed, cover for 30 seconds to help it soften without overcooking.
Season the bok choy with sugar and MSG, if using, and toss well. Transfer to a warm serving platter and set aside.
Carefully rinse and dry the wok, then return it to high heat. Add the remaining 1/2 tbsp vegetable oil.
When the wok is very hot and just beginning to smoke, add the steak in a single layer, placing fattier sides down first when possible.
Sear the steak for about 30 seconds, then toss to brown the other sides. Cook just until the beef is browned outside and still medium-rare to medium inside.
Transfer the steak and any juices over the bok choy. If liquid has collected on the platter, pour off the excess before adding the beef.
Leave about 1 to 2 tbsp of flavorful fat in the wok and discard any extra. Set the wok over medium-high heat, pour in the prepared sauce, and scrape up the browned bits from the bottom.
Bring the sauce to a simmer and cook until lightly thickened and glossy. Pour the sauce over the steak and bok choy, then serve immediately with steamed rice.
For the best texture, use ribeye or sirloin and avoid overcooking the beef. If you cannot find bok choy, baby bok choy or Chinese broccoli works well. Leftovers keep in the refrigerator for up to 2 days, though the beef is best eaten fresh.
