Ingredients
Scale
Beef Marinade
- 1 pound flank steak, thinly sliced against the grain
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon cornstarch
Vegetables and Aromatics
- 2 tablespoons vegetable oil
- 1 large yellow onion, sliced
- 2 cloves garlic, minced
- 1 tablespoon fresh ginger, minced
Sauce and Garnish
- 1 tablespoon rice vinegar
- 1 tablespoon hoisin sauce (optional)
- 1 teaspoon sesame oil
- 1 green onion, sliced (for garnish)
- Freshly ground black pepper to taste
Instructions
- Marinate the Beef: In a bowl, combine the thinly sliced flank steak with soy sauce, oyster sauce, and cornstarch. Mix thoroughly ensuring the beef is well coated. Let it marinate for at least 15 minutes to absorb the flavors and tenderize.
- Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat until hot. Add the marinated beef and stir-fry quickly for 2–3 minutes until the beef turns brown but is not fully cooked through. Remove the beef from the skillet and set aside to prevent overcooking.
- Cook the Onions and Aromatics: Add the remaining 1 tablespoon of vegetable oil to the same skillet. Add the sliced yellow onions and stir-fry for 2–3 minutes until they begin to soften. Stir in the minced garlic and ginger, cooking for another 30 seconds to release their fragrance without burning.
- Combine and Finish Cooking: Return the partially cooked beef to the skillet with the onions, garlic, and ginger. Add the rice vinegar and hoisin sauce if using. Stir well to combine all ingredients. Continue stir-frying for another 2–3 minutes until the beef is fully cooked and the sauce slightly thickens, coating the ingredients beautifully.
- Add Finishing Touches and Serve: Drizzle sesame oil over the stir-fry and toss to evenly coat. Season with freshly ground black pepper as desired. Garnish with sliced green onions for freshness and color. Serve the stir-fry hot with steamed rice for a complete meal.

- Substitute flank steak with skirt steak or sirloin if preferred or if flank steak is unavailable.
