Where to Find Fresh Lemongrass. Fresh lemongrass can be found in pretty much any Asian market, and in lots of other supermarkets these days. If you don't see it in the produce section, check the freezer case—and as a last resort, look for a tube of prepared lemongrass.

Lemongrass in Thailand is called takhrai (ตะไคร้).

Masterclass tells shoppers that when looking for quality lemongrass, avoid leaves that look dried, feel soft, or have any browning. Instead, the fronds should look vigorously green, feel appropriately heavy, and have a firm quality to them.
