Freezing lemongrass is the easiest way to keep this citrusy, floral ingredient on hand for soups, stir-fries, and curries. In just a few minutes, you can prep and store lemongrass so it stays flavorful for up to six months. No fancy tools required — just fresh stalks, a knife, and your freezer!
Cut the outer leaves and top part of the lemongrass. You’ll only need the bottom part for cooking. However, this is not to say that the top parts don’t carry any purpose. You can use them to make tea or bag up to use in marinades.
Separate the inner green leaves, chop or scissor them, and freeze them in another sealable bag. You can now puree, mince, or chop the bottom part of the lemongrass.
Ideally, lemongrass is preserved properly when it is frozen in small amounts.
Double wrapping helps prevent freezer burn. Consider wrapping it tightly in a freezer bag or cellophane before adding to a freezer safe, airtight container for final storage in the freezer.
If your plan is to preserve the lemongrass for several months, then you can use a vacuum pack to freeze it.
