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 penetrate.
- 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 slices and cook for one minute on each side until browned but still tender. Remove the beef from the pan to 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 same pan and sauté the chopped white onion for 1 to 2 minutes until slightly softened. Add the chopped bok choy and continue cooking for 2 to 3 minutes until the vegetables are tender but still bright and crisp.
- Combine and Serve: Return the cooked beef to the pan with the vegetables. Add oyster sauce, light soy sauce, and granulated sugar. Cook for about one minute, stirring constantly, until the sauce slightly thickens and coats all ingredients. Serve hot over cooked rice or stir-fry noodles. Optionally garnish with sesame seeds and sliced green onions for extra flavor and texture.
Notes
- Ribeye or sirloin are also excellent choices instead of flank steak for a tender, flavorful result.
- Serve the dish immediately after cooking for the best texture and freshness.
- Adjust the amount of oyster sauce and soy sauce to suit your personal taste preference and saltiness level.
- Use vegetable oil or a neutral oil with a high smoke point for stir-frying to avoid burning.
- If bok choy is unavailable, baby spinach or Chinese broccoli can be good substitutions.
