Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 3 tbsp oyster sauce, 1 tbsp soy sauce, 1 tsp brown sugar, 1 tsp cornstarch, and 1/4 cup water until smooth; set aside.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add 12 oz thinly sliced flank steak and stir-fry for 2-3 minutes until browned but still tender. Remove beef from wok and set aside.
  3. Step 3: Add 3 minced garlic cloves and 1 tbsp minced ginger to the wok and stir-fry for 30 seconds until fragrant.
  4. Step 4: Add 2 halved baby bok choy heads and stir-fry for 2 minutes until the leaves begin to wilt but stems remain crisp.
  5. Step 5: Return the beef to the wok, pour in the oyster sauce mixture, and toss everything together. Cook for 1-2 minutes until the sauce thickens and coats the beef and bok choy evenly. Season with 1/4 tsp black pepper and serve immediately over steamed rice or noodles.
