Ingredients
Main Ingredients
- 12 ounces beef flank steak, trimmed
- 1 tablespoon minced fresh ginger
- 1 ½ teaspoons reduced-sodium soy sauce
- 1 teaspoon dry sherry, divided (1 tsp + 1 Tbsp)
- 1 teaspoon cornstarch
- 1 teaspoon toasted sesame oil
- 2 tablespoons oyster-flavored sauce (preferably Lee Kum Kee Premium)
- 1 tablespoon vegetable oil
- 1 pound baby bok choy, trimmed and cut into 2-inch pieces (about 8 cups)
- 3 tablespoons unsalted chicken broth
Instructions
- Prepare the beef: Cut the beef flank steak with the grain into 2-inch-wide strips, then crosswise into 1/4-inch-thick slices. In a medium bowl, combine the beef with minced fresh ginger, reduced-sodium soy sauce, 1 teaspoon dry sherry, and cornstarch. Stir well until the cornstarch is fully incorporated and no longer visible. Add toasted sesame oil and stir again to lightly coat the beef.
- Mix the sauce: In a small bowl, combine the oyster-flavored sauce and the remaining 1 tablespoon dry sherry. Set this sauce mixture aside for later use.
- Cook the beef: Heat a 14-inch flat-bottomed carbon-steel wok or a 12-inch stainless-steel skillet over high heat until a drop of water vaporizes within 1 to 2 seconds. Swirl in the vegetable oil to coat the pan. Add the beef in an even layer and cook undisturbed for about 1 minute until it begins to brown. Stir-fry the beef using a metal spatula for an additional 30 seconds to 1 minute until lightly browned but not fully cooked through. Transfer the beef to a plate to rest.
- Cook the bok choy: Add the baby bok choy and chicken broth to the hot pan. Cover the pan and cook for 1 to 2 minutes until the bok choy greens turn bright green and most of the broth is absorbed.
- Finish the stir-fry: Return the beef to the pan with the bok choy. Pour in the reserved oyster sauce mixture. Stir-fry everything together for 30 seconds to 1 minute until the beef is just cooked through and the bok choy is tender-crisp. Remove from heat and serve immediately.
Notes
- You can substitute beef with chicken, tofu, shrimp, or pork depending on your preference.
- Swap baby bok choy for other stir-fry friendly vegetables such as bell peppers, mushrooms, snap peas, bamboo shoots, or shredded cabbage.
- Trim about an inch from the root of the baby bok choy to minimize waste and use almost the entire vegetable.
- Store leftovers in a covered container in the refrigerator for 3 to 4 days. Reheat on the stove or in a microwave.
- Ensure your wok or skillet is very hot before adding oil to achieve proper searing and stir-frying.
