Gai lan
A leafy vegetable with thick stems and a stronger, bitter flavor than broccoli.
Last updated
Gai lan (Brassica oleracea var. alboglabra) is a leafy green vegetable also called Chinese broccoli or Chinese kale. Its leaves are thick, flat, and glossy blue-green, with sturdy stems and small florets that look like miniature broccoli heads. This plant belongs to the alboglabra group, a name derived from Latin for "white" and "hairless." When it flowers, it produces white blossoms similar to those of hoary stock. The taste is close to broccoli but more intense and with a hint of bitterness.
This cool-season crop thrives in temperatures between 18 and 28°C and handles summer heat better than other brassicas like broccoli or cabbage. Harvesting typically happens 60 to 70 days after sowing, just before flowering begins. If the plant bolts, the stems can turn woody and tough. For market, it is usually cut when 15 to 20 cm tall, though "baby gai lan" is also grown by crowding seedlings and using heavy fertilization—these young plants look like Brussels sprouts but have looser leaves.
Broccolini is a hybrid created by crossing broccoli with gai lan.
In cooking, the stems and leaves are common in Chinese cuisine, often stir-fried with ginger and garlic, or boiled or steamed with oyster sauce. It also appears in Vietnamese, Burmese, and Thai dishes. In Chinese restaurants, especially dim sum spots, gai lan is a staple. In Americanized Chinese food, such as beef and broccoli, gai lan was frequently swapped for regular broccoli when unavailable.
Lore & Background
Gai lan is a cool season crop that grows best between 18 and 28 °C (64 and 82 °F) and withstands hotter summer temperatures better than other brassicas such as broccoli or cabbage. It is harvested around 60–70 days after sowing, just before the flowers start to bloom; the stems can become woody and tough when the plant bolts. It is generally harvested for market when 15–20 cm (6–8 in) tall, but can also be produced as 'baby gai lan' through crowding of seedlings and generous fertilization, which resembles Brussels sprouts although it has looser folds. Broccolini is a hybrid between broccoli and gai lan.
The stems and leaves of gai lan are eaten widely in Chinese cuisine, with common preparations including stir-fried with ginger and garlic, or boiled or steamed and served with oyster sauce. It is also common in Vietnamese, Burmese, and Thai cuisine, and in Chinese cuisine it is often associated with dim sum restaurants. In Americanized Chinese food, such as beef and broccoli, gai lan was frequently replaced by broccoli when gai lan was not available.
Reader's Guide
Gai lan holds significance as a distinctive leafy vegetable in East and Southeast Asian cuisines, particularly Chinese, where it is a staple in both home cooking and dim sum restaurants. Its stronger, slightly bitter flavor compared to broccoli sets it apart, and its ability to withstand hotter summer temperatures makes it a resilient crop for growers. The development of broccolini as a hybrid between broccoli and gai lan demonstrates its genetic utility in modern agriculture. The vegetable's legacy includes its adaptation in Americanized Chinese food, where it was often substituted with broccoli due to availability, highlighting its role in culinary exchange.
As a cool season crop harvested before flowering, gai lan requires careful timing to avoid woody stems, and its 'baby' version offers a different texture and presentation. Its white blossoms, resembling hoary stock, add an ornamental aspect. Overall, gai lan remains a key ingredient in diverse Asian cuisines and a subject of horticultural interest.
