Blanched gai lan is drizzled with a glossy oyster sauce and finished with a drizzle of hot oil. This healthy, low calorie family side delivers crisp texture and savory depth in every bite.
Bring a large pot of water to a rolling boil and add a generous pinch of salt.
Add the trimmed Chinese broccoli and blanch for 1.5–2 minutes until the stems are bright green and just crisp-tender. Quickly drain and arrange on a serving plate.
In a small saucepan over low heat, combine oyster sauce, soy sauce, sugar, and water. Stir until smooth and warmed but do not let it boil.
Drizzle the warm sauce evenly over the blanched broccoli.
Heat the vegetable oil in a small pan over high heat until shimmering. Carefully drizzle the hot oil over the broccoli and sauce just before serving to finish with gloss and aroma.
