Can You Freeze Leeks?
Yes, you can freeze it.
10-12 months (chopped, texture softens)
Chopped leeks freeze well (10-12 months) with the same texture-softening trade-off shared by onions and other alliums — fine for a soup or braise after thawing, less suited to a dish wanting a crisper bite. Because leeks trap dirt deep between their tightly layered structure as they grow, thorough washing (often halved and rinsed under running water) matters just as much before freezing as it does before any other use.
Slicing leeks into rounds before freezing, rather than freezing them in long strips, gives a more useful shape for most recipes, since a soup or braise typically calls for rounds or half-moons anyway, and pre-slicing means one less prep step standing between the freezer and the pot.
The dark green tops of a leek, often trimmed away and discarded before cooking, can actually be saved and frozen separately for use in a homemade stock, even though they're too tough for most other preparations — a genuinely useful way to get more total value out of a bunch before any of it is wasted.
A leek frozen without being properly washed first will still have any trapped grit locked into the frozen pieces, which won't rinse away later the way it would from fresh, unfrozen leeks — thorough washing before freezing matters even more here than before a fresh preparation, since there's no easy way to fix it after the fact.
A leek with tightly closed, unblemished layers at the base is generally fresher and holds up to washing and freezing a bit better than one with loose outer layers.
