🌿 Ingredients You’ll Need
For the Beef:
1 lb (450g) flank steak, thinly sliced against the grain
2 tbsp cornstarch
2–3 tbsp vegetable oil (for frying)
For the Sauce:
½ cup soy sauce
½ cup water
⅓ cup brown sugar (adjust to taste)
2–3 garlic cloves, minced
1 tsp ginger, grated
½ tsp red pepper flakes (optional for heat)
For Serving:
Cooked white or brown rice
Sliced green onions (for garnish)
Sesame seeds (optional)
🔹 Step-by-Step Instructions
Step 1: Prepare the Beef
Slice the flank steak thinly against the grain.
Toss the slices with 2 tbsp cornstarch until evenly coated. This helps create a crispy, caramelized exterior.
Step 2: Fry the Beef
Heat 2–3 tbsp vegetable oil in a large skillet or wok over medium-high heat.
Add the beef in batches to avoid overcrowding.
Cook for 2–3 minutes per side until browned and slightly crispy. Remove and set aside.
Step 3: Make the Sauce
In the same skillet, add minced garlic and ginger. Sauté for 30 seconds until fragrant.
Add soy sauce, water, brown sugar, and red pepper flakes (if using).
Bring the sauce to a simmer and cook for 2–3 minutes until slightly thickened.
Step 4: Combine Beef and Sauce
Return the cooked beef to the skillet and toss to coat evenly in the sauce.
Cook for an additional 1–2 minutes, allowing the flavors to meld.
Step 5: Serve and Garnish
Serve over steamed rice.
Garnish with sliced green onions and sesame seeds for extra flavor and presentation.
