Instructions

  1. Step 1: Toss 1 lb thinly sliced flank steak with 3 tbsp soy sauce and 1 tbsp cornstarch in a bowl until evenly coated; set aside for 10 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the marinated beef in a single layer and stir-fry for 2-3 minutes until browned but still tender. Remove beef and set aside.

  5. Step 5: Return the beef to the wok along with 1 tsp brown sugar and 1 tsp sesame oil; toss everything together for 1-2 minutes until the sauce slightly thickens and coats the ingredients.
  6. Step 6: Garnish with 2 sliced scallions and serve immediately with steamed rice.
