A classic Cantonese dim sum staple, gai lan with oyster sauce pairs the slightly bitter, leafy stems of Chinese broccoli with a glossy umami sauce. The stalks are briefly blanched for a crisp-tender snap, then finished with garlic, ginger, and a thickened oyster sauce glaze.

Ingredients
For the greens
- 1.5 lb gai lan (Chinese broccoli), tough ends trimmed and lower stems peeled
- 2 tsp neutral oil
- 1/2 tsp salt, for the blanching water
For the oyster sauce glaze
- 3 tbsp oyster sauce
- 1 tbsp Shaoxing wine
- 1 tsp light soy sauce
- 1 tsp granulated sugar
- 1/2 cup low-sodium chicken stock or water
- 1 tsp cornstarch mixed with 2 tbsp cold water
- 1 tsp toasted sesame oil
For the aromatic finish
- 2 tbsp neutral oil
- 4 garlic cloves, finely minced
- 1 tbsp finely grated fresh ginger
- 2 small red chili peppers, thinly sliced (optional)
Directions
- Bring a large pot of water to a rolling boil, add the salt and 2 tsp neutral oil, then blanch the gai lan in batches for 2 to 3 minutes until stems are just tender but still bright green.
- Transfer the blanched gai lan with tongs to an ice bath for 30 seconds to lock in the color, then drain well and arrange on a warmed serving platter in a single layer.
- In a small bowl whisk together the oyster sauce, Shaoxing wine, light soy sauce, sugar, and chicken stock until the sugar dissolves; set aside near the stove.
- Heat the 2 tbsp neutral oil in a small saucepan over medium heat until shimmering, then add the minced garlic and grated ginger and stir-fry for 30 to 45 seconds until fragrant but not browned.
- Pour in the oyster sauce mixture and bring to a gentle simmer, whisking constantly for about 2 minutes to meld the flavors.
- Stir the cornstarch slurry once more and stream it into the simmering sauce while whisking; cook 30 to 60 seconds until the glaze coats the back of a spoon and turns glossy.
- Off heat, stir in the toasted sesame oil, then spoon the hot glaze generously over the arranged gai lan, letting it pool around the stems.
- Scatter the sliced red chili on top if using, and serve immediately while the stems still have their crisp bite.
Cook’s Notes
- Always peel the lower 2 to 3 inches of the gai lan stems; the fibrous outer skin can stay tough even after blanching.
- An ice bath after blanching is essential for keeping the vivid emerald color and crisp texture typical in Cantonese restaurants.
- Use a premium oyster sauce (such as Lee Kum Kee Premium or Megachef) for the cleanest, sweetest umami; cheaper brands tend to be saltier and one-dimensional.
- For deeper flavor, briefly sauté 2 tbsp dried shrimp (soaked and chopped) with the garlic before adding the sauce liquid.
- Gai lan stems take longer to cook than the leaves, so stand them upright in the boiling water with leaves just above the surface for even cooking.
