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 cornstarch, soy sauce, rice vinegar, beaten egg white, sesame oil, diced garlic, and grated ginger. Mix everything 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 beef in batches and cook for one minute on each side until browned but still tender. Remove from the pan to a clean plate lined with paper towels to drain excess oil.
- Sauté the Vegetables: Add another drizzle of vegetable oil to the pan. Cook the chopped onions for 1-2 minutes until slightly translucent. Add the bok choy and continue cooking for 2-3 minutes until the vegetables are tender yet crisp.
- Combine and Serve: Return the cooked beef to the pan with the vegetables. Toss with oyster sauce, light soy sauce, and granulated sugar. Cook for about one minute, stirring constantly until the sauce thickens slightly and coats the ingredients. Serve immediately over steamed rice or stir-fried noodles, garnished optionally with sesame seeds and green onions.
Notes
- Ribeye or sirloin can be substituted for flank steak for a different texture and flavor.
- The dish is best served immediately to enjoy the optimal flavor and tender texture of the beef and vegetables.
- Adjust the amount of oyster sauce and soy sauce based on your taste preference for more or less saltiness and umami.
- Use vegetable oil for cooking as it tolerates high heat well for stir-frying.
- Ensure the beef slices are cut thinly against the grain for maximum tenderness.
