Culinary Heritage and Significance

Water spinach is native to Southeast Asia and is widely consumed in countries like Indonesia, Malaysia, Thailand, and the Philippines. It is also a staple in Chinese cuisine, particularly in Cantonese and Hakka dishes. Stir-fried water spinach is beloved for its tender stems and leaves, which cook quickly and retain their vibrant green color when stir-fried over high heat. The dish reflects the influence of Asian culinary traditions, where fresh vegetables are often stir-fried to preserve their nutrients and natural flavors.


To prepare stir-fried water spinach, gather the following ingredients:

  • Water Spinach (Kangkung/Ong Choy): 1 bunch, about 1 lb, washed and trimmed
  • Garlic: 3 cloves, minced
  • Red Chili (optional): 1, thinly sliced
  • Vegetable Oil: 2 tbsp
  • Soy Sauce: 1 tbsp
  • Oyster Sauce: 1 tbsp
  • Salt: 1/2 tsp
  • Sugar: 1/2 tsp
  • Water or Chicken Stock: 2 tbsp (optional, for cooking)

Cooking Instructions

  1. Prepare the Water Spinach:
    • Rinse the water spinach thoroughly under cold water. Trim off any tough stems and cut into manageable lengths, about 3 inches long.
  2. Heat the Wok or Skillet:
    • Heat vegetable oil in a large wok or skillet over high heat until it starts to shimmer.
  3. Stir-Fry Aromatics:
    • Add minced garlic and red chili (if using) to the hot oil. Stir-fry for about 30 seconds until fragrant, being careful not to burn the garlic.
  4. Stir-Fry the Water Spinach:
    • Add the water spinach to the wok. Stir-fry continuously for 1-2 minutes until the leaves begin to wilt and the stems are tender-crisp.
  5. Season the Dish:
    • Drizzle soy sauce and oyster sauce over the stir-fried water spinach. Sprinkle with salt and sugar. If the dish appears dry, add 2 tablespoons of water or chicken stock to create steam and help wilt the leaves further.
  6. Combine and Serve:
    • Toss everything together to coat the water spinach evenly in the sauce. Stir-fry for another 1-2 minutes until the sauce thickens slightly and coats the vegetables.
  7. Garnish and Serve:
    • Remove from heat and transfer the stir-fried water spinach to a serving dish. Garnish with additional red chili slices (if desired) for added spice. Serve hot as a nutritious side dish alongside steamed rice or as part of a larger Asian-inspired meal.

Tips for Perfect Stir-Fried Water Spinach

  • Handling Water Spinach: Cut the water spinach into similar-sized pieces to ensure even cooking.
