Ingredients

Scale

Beef Marinade:

  • 1 lb flank steak
  • 1.5 tbsp cornstarch (or potato starch)
  • 2 tsp Shaoxing wine (or rice vinegar)
  • 2 tsp sesame oil
  • 1/2 tsp baking soda

Stir-fry and Sauce:

  • 1 medium white onion (sliced and separated into layers)
  • 4 scallions (cut into 2-inch segments, whites and greens separated)
  • 4 cloves garlic (minced)
  • 1 tbsp vegetable oil (for stir-frying vegetables)
  • 1 tbsp vegetable oil (for cooking beef)
  • 1 tbsp Shaoxing wine (or rice vinegar)
  • 1 tbsp oyster sauce (or vegetarian stir fry sauce)
  • 1 tbsp regular soy sauce
  • 1/2 tbsp dark soy sauce (or substitute regular soy sauce)
  • 1 tsp cornstarch (or potato starch)
  • 1/4 tsp black pepper (or white pepper)
  • 4 tbsp cold water
  • 1 tsp white granulated sugar (or brown sugar)

Instructions

  1. Slice the beef: Slice flank steak against the grain on an angle into 1/4-inch thin slices. For easier slicing, freeze the beef for 40 minutes until firm. Transfer the sliced beef to a medium bowl.
  2. Marinate the beef: Combine the marinade ingredients (1.5 tbsp cornstarch, 2 tsp Shaoxing wine, 2 tsp sesame oil, 1/2 tsp baking soda) with the sliced beef. Marinate at room temperature for 15-20 minutes to tenderize and infuse flavor.
  3. Prepare the sauce: In a small bowl, stir together the sauce ingredients: 1 tbsp Shaoxing wine, 1 tbsp oyster sauce, 1 tbsp soy sauce, 1/2 tbsp dark soy sauce, 1 tsp cornstarch, 1/4 tsp black pepper, 4 tbsp cold water, and 1 tsp sugar. Set aside.
  4. Cook onions and scallion whites: Heat 1 tbsp vegetable oil in a large skillet over low heat. Add the sliced white onions and scallion whites and stir-fry for 30 seconds. Remove from the skillet and set aside to keep them lightly cooked but crisp.
  5. Brown the beef: Increase the skillet heat to medium-high. Add 1 tbsp vegetable oil and spread the marinated beef in a single layer. Cook undisturbed for 2-3 minutes until browned on one side, then flip and cook for another 2-3 minutes until the beef is browned and just cooked through.
  6. Add the sauce: Reduce heat to medium, pour the prepared sauce into the skillet in a circular motion. Stir-fry quickly for 30-60 seconds until the sauce thickens and coats the beef evenly.
  7. Combine all ingredients: Return the cooked onions and scallion whites to the skillet along with the minced garlic and scallion greens. Stir-fry for another 30-60 seconds to blend all the flavors and heat through. Remove from heat immediately to preserve texture.
  8. Serve: Serve the beef and onion stir fry hot over plain steamed rice with your favorite vegetables for a complete meal.

Notes

  • Freezing the beef slightly before slicing helps achieve thin, even slices.
  • Baking soda in the marinade tenderizes the beef effectively.
  • Use Shaoxing wine for authentic flavor, substitute rice vinegar if unavailable.
  • Adjust sugar and soy sauce to taste for sweetness and saltiness balance.
  • Serve immediately to enjoy the beef tender and vegetables crisp.
