Water chestnuts (Eleocharis dulcis) are aquatic tubers native to Southeast Asia, cultivated primarily in China, Japan, and other East Asian regions. Despite their name, they are not true nuts but rather the corms (underground stems) of a sedge plant grown in muddy, flooded conditions. The bulbous tubers have a distinctive dark brown papery skin that must be peeled to reveal the crisp, white flesh beneath. Water chestnuts possess a mild, slightly sweet flavor with a remarkable texture—firm and crunchy when raw or lightly cooked, reminiscent of jicama or raw potato but with a more delicate quality. They contain minimal flavor compounds of their own, serving primarily as a vehicle for textural contrast in dishes.

The primary varieties grown commercially are the Chinese water chestnut, which is larger and more commonly available, and smaller Japanese varieties. Fresh water chestnuts are seasonal, while canned versions (often packed in brine or syrup) are available year-round and constitute the majority of Western market supply.

Water chestnuts are fundamental to East Asian cuisines, particularly Chinese stir-fries where their crisp texture provides essential contrast to soft proteins and vegetables. They are frequently diced and incorporated into dim sum preparations, used in lettuce wraps, added to fried rice, and featured in sweet-and-sour dishes. Beyond Asian cooking, they appear in Vietnamese spring rolls and Thai preparations. Their mild flavor and firm crunch make them valuable for maintaining textural interest in cooked dishes—they remain crisp even after brief cooking. Water chestnuts are typically peeled (fresh varieties require manual peeling; canned varieties are pre-peeled), halved or diced depending on preparation, and added toward the end of cooking to preserve their signature crunch. When eating canned water chestnuts, rinsing removes excess brine or syrup.
