Full Ingredients

For the Greens

• 1 lb (450 g) gai lan (Chinese broccoli), tough ends trimmed; stems and leaves separated
• 1 tbsp kosher salt (for blanching water)
• Ice for ice bath (about 3 cups)

Oyster Sauce Dressing

• 2 tbsp oyster sauce
• 2 tbsp hot water
• 1 tsp light soy sauce
• 1/2 tsp granulated sugar
• 1 tsp toasted sesame oil

Garlic Oil and Finish

• 2 tbsp neutral oil (canola, peanut, or grapeseed)
• 3 garlic cloves, finely minced (about 1 tbsp)
• Pinch ground white pepper, optional

Step-by-Step Instructions

Step 1: Prep the gai lan

Rinse the gai lan well. Trim off any dried or woody ends. Separate thicker stems from the leafy tops so each cooks evenly. If any stems are very thick (over 3/4 inch), slice them in half lengthwise.

Step 2: Mix the oyster sauce dressing

In a small bowl, whisk together the oyster sauce, hot water, light soy sauce, sugar, and sesame oil until smooth and glossy. Set aside.

Step 3: Boil water and set an ice bath

Bring 3 quarts (2.8 L) water to a rolling boil (212°F/100°C) in a wide pot. Stir in 1 tablespoon kosher salt. Fill a large bowl with ice and cold water for shocking the greens after blanching.

Step 4: Cook the gai lan (blanch or stir-fry)

To blanch: Add stems to the boiling water and cook 1 to 1 1/2 minutes. Add leaves and cook 30 to 45 seconds more until vivid green and crisp-tender. Immediately transfer to the ice bath for 30 seconds to stop cooking. Drain well and pat dry to avoid diluting the sauce.

To stir-fry: Heat 1 tablespoon neutral oil in a wok or large skillet over high heat until lightly smoking. Add stems and cook 1 minute, tossing. Add leaves and 2 tablespoons water; stir-fry 1 to 2 minutes until crisp-tender and bright green. Remove from heat.

Step 5: Make the fragrant garlic oil

In a small saucepan, heat 2 tablespoons neutral oil over medium heat until shimmering (about 300°F/150°C), 30 to 60 seconds. Add minced garlic and cook, stirring, for 30 to 60 seconds just until pale golden and fragrant. Remove from heat immediately to prevent scorching.

Step 6: Plate and dress

Arrange the gai lan on a warm platter with stems aligned and leaves layered on top. Drizzle the hot garlic oil evenly over the greens, then spoon the oyster sauce dressing in ribbons down the center. Finish with a pinch of white pepper if using.

Step 7: Serve

Serve right away while the greens are crisp-tender and glossy. This dish pairs beautifully with steamed rice and simple stir-fries.

Pro Tips

• Separate stems and leaves so nothing overcooks; stems need a head start.
• Dry the greens well after blanching—excess water thins the sauce and dulls flavor.
• Garlic browns fast; pull it as soon as it turns pale golden to avoid bitterness.
• If your oyster sauce is very thick, whisk in an extra 1 to 2 teaspoons hot water until it falls off the spoon in a slow ribbon.
• For restaurant-style sheen, toss the greens with 1 teaspoon neutral oil before saucing.

Variations

• Vegetarian: Use mushroom-based “vegetarian oyster sauce.”
• Ginger-Garlic Oil: Add 1 teaspoon very finely minced ginger with the garlic for a brighter aroma.
• Spicy: Finish with 1 to 2 teaspoons chili crisp or a few drops of chili oil.

Storage & Make-Ahead

Blanch the gai lan up to 24 hours ahead: shock, drain thoroughly, and refrigerate wrapped in paper towels in an airtight container. Reheat by dipping in boiling water for 15 seconds or a quick 30–60 second toss in a hot skillet. The oyster sauce dressing can be mixed 3 days ahead and refrigerated; bring to room temperature or warm gently before serving. Garlic oil is best fresh but can be made up to 1 day in advance; rewarm gently. Leftovers keep 2 to 3 days refrigerated; reheat briefly to preserve texture. Do not freeze.
