Long beans

Long beans are edible at all stages of growth. Tender green leaves are an important food source in Africa and are prepared like spinach. Immature pods are used in the same way as snap beans. Peas (seeds) can be boiled as a fresh vegetable, or may be canned or frozen. Dry mature peas are suitable for boiling and canning and can be used in soups or salads.

Long beans are of a different genus than green beans and are vigorous climbing annual vines. They are a member of the cowpea family and grow to about 18-inches long. Colors range from dark green to silver, burgundy and mosaic, which have pods that are speckled purple, red and green. Elmer’s Farm grows akasanjaku, a highly prized sweet variety the produces long and slender pods that are stringless. Seeds are red and the bean can grow up to16 inches long.

Long beans are also called yard long beans, asparagus beans, bora, bodi, snake beans and Chinese long beans. Elmer and Ailyn are from Ilocos Norte, a Philippines province where shorter varieties (about one foot) are called otong and longer varieties are called sitaw. China has many names including cheung kong tau. In India they’re called lobia; kacang panjang in Indonesia; juroku sasage mame in Japan; kacang belut in Malaysia; diya mekaral in Sri Lanka; tau afuk yaou in Thailand and dau dua in Vietnam.


On Kauai, long beans can be grown year-round.

What to look for

Select pods that are smooth, firm and about the diameter of a pencil. Like green beans, over-mature pods can be tough.


Keep dry and store in the refrigerator for up to one week.


Long beans are crisp, tender and delicious. You can substitute them in recipes that use snap beans or string beans. Prepare by cutting into 2-inch sections and deep-fry, stir-fry, steam or use in soups and salads. Another popular option is to chop them into very short sections and fry them in an omelet.

In West India, they are often stir-fried with potatoes and shrimp. They are also used in Chinese stir-fries with other vegetables and meat. In Malaysian cuisine, they are often stir-fried with chilies and shrimp paste or used in cooked salads.

In the Philippines, they are stir-fried with soy sauce, garlic and hot peppers; used in a vegetable dish call utan; and stewed in dishes such as pinakbet and dinengdeng. In a dish called agaya, long bean seeds are cooked with vegetables and the buds of the alukon tree (Alleaenthus luzonicus).

Aylin likes to make long bean and chicken adobo by stir-frying garlic, ginger, onion and chicken in a small amount of oil until the chicken is mostly cooked and a little liquid remains. She adds long beans, soy sauce, apple cider vinegar, bay leaf and whole black peppercorns and cooks the mixture until the liquid reduces to a vicious brown sauce. She recommends adjusting the soy sauce and vinegar ratio to suit your taste, but says to use 1 cup of soy sauce and 2 tablespoons of vinegar as a general guide.


Long beans contain peas that sometimes have black eyes, just like black-eyed peas, which are also cowpeas.

Health benefits:

Cowpeas are very low in saturated fat, cholesterol and sodium. They are a good source of protein, thiamin, iron, magnesium, phosphorus and copper, and a very good source of dietary fiber, folate and manganese. One cup contains 200 calories, 13 grams of protein, 11 grams of fiber and 24 percent of the Daily Value for iron.

Protein in peas is rich in the amino acids lysine and tryptophan.

However, peas are low in methionine and cystine and should be combined with other vegetables or animal protein.
