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 flank steak to a resealable bag with cornstarch, soy sauce, rice vinegar, beaten egg white, sesame oil, diced garlic, and grated ginger. Mix thoroughly so the beef is fully coated. Refrigerate for at least 20 minutes to develop flavor and tenderize the meat.
- Cook the Beef: Heat a large skillet over medium-high heat and add a generous drizzle of vegetable oil. Once the oil is hot, add the marinated beef in a single layer and cook for about one minute on each side until browned but not overcooked. Remove the beef and place it on a clean plate lined with paper towels to drain excess oil. Cook in batches if needed to avoid overcrowding the pan.
- Sauté the Vegetables: Add another drizzle of vegetable oil to the same skillet. Add the chopped white onion and cook for 1 to 2 minutes until slightly softened. Add the bok choy and continue cooking for 2 to 3 minutes until the vegetables become tender but still crisp.
- Combine and Serve: Return the cooked beef to the skillet with the sautéed vegetables. Add oyster sauce, light soy sauce, and granulated sugar. Stir constantly and cook for about 1 minute until the sauce thickens slightly and coats the beef and vegetables evenly. Serve hot over steamed rice or stir-fry noodles, garnished optionally with sesame seeds and sliced green onions.
Notes
- Ribeye or sirloin can be substituted for flank steak for a more tender cut.
- Serve immediately to enjoy the best flavor and texture of the dish.
- Adjust the amount of oyster sauce and soy sauce to suit your taste preferences.
- Using vegetable oil for stir-frying helps achieve a good sear on the beef and prevents sticking.
- Ensure the beef slices are thin for quick cooking and tenderness.
