Ingredients
Scale
Marinated Beef
- 1 pound beef flank steak
- 2 tablespoons cornstarch
- 1 tablespoon soy sauce
- 1 tablespoon rice vinegar
- 1 beaten egg white
- 1 tablespoon sesame oil
- 2 teaspoons diced garlic
- 1 teaspoon grated ginger
Vegetables
- 1 small white onion, chopped
- 2 bunches of bok choy
Oyster Sauce
- 2 tablespoons oyster sauce
- 1 tablespoon light soy sauce
- 1 teaspoon granulated sugar
- Optional: sesame seeds
- Optional: green onions
Instructions
- Marinate the Beef: Add thinly sliced beef to a resealable bag with the cornstarch, soy sauce, rice vinegar, beaten egg white, sesame oil, diced garlic, and grated ginger. Mix everything thoroughly so the beef is well coated. Refrigerate for at least 20 minutes to allow flavors to develop.
- Cook the Beef: Heat a large skillet over medium-high heat and add a generous drizzle of vegetable oil. When the oil is hot, add the marinated beef slices and cook for one minute on each side until browned but still tender. Remove the beef from the pan onto a clean plate lined with paper towels. Cook in batches if necessary to avoid overcrowding and overcooking.
- Sauté the Vegetables: Add another drizzle of vegetable oil to the skillet. Sauté the chopped white onion for 1 to 2 minutes until slightly softened. Add the bok choy and continue cooking for 2 to 3 minutes until the vegetables are tender but still crisp.
- Combine and Serve: Return the cooked beef to the pan with the vegetables. Add the oyster sauce, light soy sauce, and granulated sugar. Toss everything together and cook for one minute, stirring constantly until the sauce slightly thickens and coats all ingredients evenly. Serve immediately over steamed rice or stir-fry noodles, garnished optionally with sesame seeds and green onions.
Notes
- Ribeye or sirloin can be substituted for flank steak if preferred.
- Serve the dish immediately after cooking for the best texture and flavor.
- Adjust the amount of oyster sauce or soy sauce to suit your taste preferences.
- Use vegetable oil for stir-frying to maintain a neutral flavor and high smoke point.
