Ingredients You'll Need

Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.

  • 1 lb Kailan (Chinese Broccoli) (trimmed and cut into 2-inch pieces)
  • 4 cloves Garlic (minced)
  • 3 tbsp Oyster Sauce
  • 1 tbsp Soy Sauce (light or regular)
  • 1 tsp Sesame Oil
  • 1 tsp Cornstarch
  • 2 tbsp Water
  • 2 tbsp Vegetable Oil
  • 1/2 tsp Sugar
  • 1/4 tsp White Pepper

Step-by-Step Instructions

  1. 1

    Prepare the kailan by thoroughly washing and trimming the leaves and stems. Cut the kailan into 2-inch pieces, separating the thicker stems from the leaves as they require slightly different cooking times. This ensures even cooking and a consistent texture.

    ~5 min

    Tip: Soaking the kailan in cold water for a few minutes can help revive it if it's looking wilted.
  2. 2

    Bring a large pot of water to a rolling boil. Add a pinch of salt and a drizzle of vegetable oil to the boiling water. The salt seasons the kailan from the inside out, while the oil helps retain its vibrant green color.

    ~2 min

    Tip: Don't overcrowd the pot, as this will lower the water temperature and result in unevenly cooked kailan.
  3. 3

    Blanch the kailan stems for about 30 seconds, then add the leaves and blanch for another 15-20 seconds, or until the kailan is bright green and slightly tender but still crisp. Over-blanching will result in mushy kailan, so keep a close eye on it.

    ~1 min

    Tip: The stems will take longer to cook, hence the staggered addition.
  4. 4

    Immediately transfer the blanched kailan to an ice bath to stop the cooking process and preserve its vibrant green color and crisp texture. This is crucial for achieving that desirable tender-crisp consistency.

    ~1 min

    Tip: Ensure the ice bath is cold enough to rapidly cool the kailan.
  5. 5

    While the kailan is cooling, prepare the sauce. In a small bowl, whisk together the oyster sauce, soy sauce, sesame oil, cornstarch, water, sugar, and white pepper until well combined. The cornstarch acts as a thickening agent, creating a glossy and flavorful sauce.

    ~2 min

    Tip: Taste the sauce and adjust the seasoning to your preference. You may want to add a touch more sugar or soy sauce depending on your taste.
  6. 6

    Drain the kailan thoroughly and set aside. Make sure all excess water is removed as it will dilute the sauce and prevent it from clinging to the kailan.

    ~1 min

    Tip: Use a salad spinner or pat the kailan dry with paper towels.
  7. 7

    Heat a wok or large skillet over high heat until smoking hot. Add the vegetable oil, swirling to coat the wok. A properly heated wok is essential for achieving 'wok hei'.

    ~1 min

    Tip: If you don't have a wok, a cast iron skillet is a good alternative.
  8. 8

    Add the minced garlic to the hot oil and stir-fry for about 15-20 seconds, or until fragrant and lightly golden. Be careful not to burn the garlic, as it will turn bitter.

    ~1 min

    Tip: Keep the garlic moving constantly to prevent burning.
  9. 9

    Add the drained kailan to the wok and stir-fry for about 1 minute, tossing constantly to coat it with the garlic-infused oil. This step helps to further develop the 'wok hei' flavor.

    ~1 min

    Tip: Work in batches if necessary to avoid overcrowding the wok.
  10. 10

    Pour the prepared sauce over the kailan and stir-fry for another 1-2 minutes, or until the sauce has thickened and evenly coats the kailan. The sauce should be glossy and clinging to the vegetables.

    ~2 min

    Tip: Adjust the heat as needed to prevent the sauce from burning.
  11. 11

    Serve immediately while hot. The kailan is best enjoyed fresh, while the texture is still at its peak.

    Tip: Garnish with a sprinkle of sesame seeds or fried garlic for added flavor and visual appeal.
