Ingredients
  

Beef Stir-Fry Ingredients
  • 1 lb (450g) Flank steak thinly sliced against the grain
  • 5 heads Baby bok choy halved lengthwise
  • 1.5 cups (300g) Long-grain white rice uncooked
  • 1/4 cup (60ml) Soy sauce
  • 2 tbsp (30ml) Oyster sauce
  • 1 tbsp (8g) Cornstarch mixed with 1 tbsp water
  • 3 cloves Garlic minced
  • 1 tbsp (6g) Ginger freshly grated
  • 2 tbsp (30ml) Vegetable oil
  • 1 tbsp (9g) White sesame seeds for garnish
  • 2 stalks Green scallions thinly sliced

Equipment

  • 1 Large Wok or Cast Iron Skillet Essential for high-heat searing.
  • 1 Chef's knife For thin beef slicing.

Instructions
 

Preparation
  1. Rinse the rice and steam according to package directions. Keep warm and covered until ready to serve.
  2. In a bowl, whisk together soy sauce, oyster sauce, garlic, ginger, and the cornstarch slurry until no lumps remain.
Cooking
  1. Heat oil in a wok over high heat. Add beef strips in a single layer. Sear until a deep golden-brown crust forms (about 90 seconds), then flip and cook for 1 minute more. Remove beef.
  2. Add bok choy halves to the pan. Sauté for 2-3 minutes until leaves are bright green and wilted, but stems remain tender-crisp.
  3. Return beef to the pan. Pour the sauce over and toss for 1 minute until the sauce becomes thick and glossy, coating everything evenly.

Notes

Place the beef in the freezer for 20 minutes for easier thin slicing.
Always whisk your cornstarch slurry right before adding to the pan as it settles quickly.
