Step-by-Step Cooking Instructions

Pre-Cooking Prep

Slice the beef thinly against the grain. Toss it with cornstarch until evenly coated. Set aside for 10 minutes. Chop green onions and mince garlic and ginger.

Cooking Method

Heat oil in a large skillet or wok over medium-high heat. Add the beef in a single layer and cook for 2–3 minutes per side until browned and crispy. Cook in batches if needed. Remove beef and set aside.

In the same skillet, lower heat to medium. Add garlic and ginger and cook for 30 seconds until fragrant.

Stir in soy sauce, brown sugar, and water. Simmer for 2–3 minutes until slightly thickened.

Return the beef to the skillet along with green onions. Toss everything together and cook for 1–2 minutes until the sauce coats the beef evenly.

Doneness or Texture Check

The beef should be tender with crisp edges, and the sauce should be glossy and lightly thickened—not watery.

Resting or Final Touches

Turn off the heat and let the dish rest for 2–3 minutes. Taste and adjust seasoning if needed.
