Can You Freeze Kimchi?

Checked against sources

Yes, and freezing kimchi does something useful: it halts the lactic fermentation that would otherwise keep souring it in the fridge. Freeze it once the tang hits a level you like, sealed against the brine expanding, and it holds for one to three months. Expect softer cabbage after thawing, so steer frozen kimchi toward stews, fried rice, and pancakes.

Can you freeze kimchi?

Yes — it freezes well
How long it keeps frozen
About 1 to 3 months for best qualityHeld solid at 0 °F (−18 °C) kimchi stays safe far longer; the limit is texture, as the cabbage keeps softening the longer it sits frozen.
How to freeze it
  1. Let the kimchi ferment to the sourness you enjoy first, since freezing locks that stage in place.
  2. Portion it into small airtight tubs or freezer bags, leaving an inch of headspace for the brine to expand.
  3. Press out the air, seal, then double-bag to keep the garlic-and-chilli smell from spreading through the freezer.
  4. Label with the date and freeze the portions flat so they stack neatly and thaw quickly.
How to thaw & use
Thaw it overnight in the refrigerator, drain off the extra liquid, and use it in cooking — the soft, still-tangy result shines in kimchi stew, fried rice, or savoury pancakes rather than as a fresh side.
Texture & quality
Freezing ruptures the cabbage's cell walls, so thawed kimchi comes back limp and a little watery instead of crunchy, and some of its live probiotic cultures will not survive the freeze-thaw. The bold sour-and-spicy flavour stays intact, which is exactly why frozen kimchi belongs in cooked dishes where crunch no longer matters.

Frequently asked questions

Does freezing kill the probiotics in kimchi?

Freezing pushes the probiotic bacteria into dormancy rather than killing them outright, but some cultures break down during thawing. Expect frozen-then-thawed kimchi to carry fewer live probiotics than fresh refrigerated kimchi.

Can you freeze kimchi in glass jars?

You can, but leave at least an inch or two of headspace because the brine expands as it freezes and can crack the glass. Rigid plastic tubs or freezer bags are the safer choice.

Will frozen kimchi keep fermenting after it thaws?

Yes. Once it is back at refrigerator temperature the lactic fermentation slowly restarts, so the kimchi will gradually sour again. Use thawed kimchi within about a week for the best flavour.

Should you freeze kimchi young or fully fermented?

Freeze it at whatever stage you like to eat it, because freezing locks in the current level of sourness. If you prefer a milder tang, freeze it younger; for a deeper funk, let it ferment longer first.
