Chinese Broccoli Oyster Sauce (Gai Lan Oyster Sauce)

Chinese Broccoli, some people also call it Gai Lan, Kai Lan, Chinese Kale, or Asian Broccoli, is probably one of my favorite Asian vegetables of all time. The gai lan stems are thick and crunchy and the deep green leaves are soft and tender.

I love stir-frying gai lan with garlic sauce or hot water blanch and drizzle with a little vegetarian oyster sauce. Either way, this vegetable brings back wonderful memories of my time with my family when we enjoy dim sum together on Sunday mornings.

What Is Gai Lan (Chinese Broccoli)?

Gai lan (or Kai lan) is Cantonese pronunciation of Chinese broccoli. Jie lan 芥蘭 is the Mandarin character and pronunciation. Some people also refer to it as Chinese kale or Asian broccoli.

Chinese broccoli has thick stems and deep blue-green color leaves. It has a slightly bitter flavor than Western broccoli so to remove the bitter flavor it’s quite common to hot water blanch the broccoli first before cooking.

How To Cook Chinese Broccoli Gai Lan (3 different ways)

There are three common ways to prepare Gai Lan –

  1. Hot water blanch
  2. Stir-fry
  3. Steam.

The best way to ensure that your Chinese kale cooks perfectly is to cook the stems and the leaves separately because Chinese Broccoli stems are much thicker than the leaves so the stems need longer time to cook.

To make Chinese broccoli with vegetarian oyster sauce, I recommend blanching the broccoli stems first. To make stir-fried gai lan recipe in garlic sauce, I prefer sautéing the stems first before adding the leafy parts. For steaming, separate the stems from the leaves so you can steam the stems separately from the leaves.

How to make Chinese Broccoli with Oyster Sauce Recipe

This dish uses hot water blanched Chinese broccoli so here are the steps to make this recipe:

  1. Prep: Trim about half to one-inch bottom ends of the Chinese broccoli.
  2. Rinse: Plunge them cold water 2-3 times.
  3. Blanch: Season the hot boiling water with a few pinches of salt. Similar to how to blanch yu choy, blanch the Chinese broccoli stems about 45 seconds and the leafy parts about 15 seconds.
  4. Shock: To stop the cooking and keep the Chinese broccoli in vibrant green color, shock the vegetables in a bowl of cold water for a few seconds then gently squeeze the leaves to remove the water.
  5. Serve: Drizzle vegetarian oyster sauce on top of the blanched Chinese broccoli. If you like, drizzle with toasted sesame oil and sprinkle with toasted sesame seeds.

  • 0.75-1 lb. Chinese broccoli, gai lan

Sauce For Vegetables:


  • Bring a large pot of water to boil.
  • To prepare the Chinese broccoli, slice off about ½ inch of the stems from the bottom end. Rinse them well.
  • With both of your hands holding the top portion of the leafy parts, carefully dip the stems into the boiling water. Hold your position and blanch the stems for about 45 seconds then release the entire broccoli bundle and blanch for an additional 15 seconds.
  • Use a large slotted spoon to scoop out the broccoli and shock in cold water. This will keep the broccoli crunchy and in deep green color. Gently squeeze the leafy parts to remove the water. Place them on a serving tray.
  • Combine homemade vegetarian oyster sauce with sesame oil and coconut aminos. Spoon the sauce over the Chinese broccoli one tablespoon at a time until your desired quantity. The more sauce the stronger flavor and saltier it will be.
  • Sprinkle with toasted sesame seeds, if using. Serve at room temperature or chilled.


  • My vegetarian oyster sauce is made with shiitake, ginger and dates. It has no additives and preservatives. It’s a wonderful sauce for Chinese stir-fries, vegetables, and chilled side dishes. I highly recommend you give it a try. It’s easy to make!
  • Note: If you are using store bought vegetarian oyster sauce or the regular oyster sauce (with oyster extract), the store bought version is much saltier than my homemade version. A rough conversion is as follows: 1 tsp store bought oyster sauce = 1 tbsp I Heart Umami homemade vegetarian oyster sauce. 
  • Alternatively, If you don’t have the vegetarian oyster sauce handy, substitute the 2-2.5 vegetarian oyster sauce in the recipe with 2 tbsp coconut aminos plus sea salt to taste.
