Can You Freeze Galangal? Whole, Sliced or as Paste

Found fresh galangal and bought more than one curry’s worth? You can freeze it, but it costs you something, and how much is where two Thai cooking writers part ways. Leela of SheSimmers finds freezing changes its taste, aroma and texture “quite a bit” and doesn’t recommend it,¹ while Pailin Chongchitnant of Hot Thai Kitchen says frozen galangal will work in tom yum when you can’t get fresh.² Even Leela says frozen galangal still works in a curry paste. And if you’ll use it soon, the fridge (almost two weeks, wrapped) may be the better bet.

At a glance

Question	Short answer
Can you freeze it?	Yes. Whether you should depends on the dish (see below).
What changes?	One cook finds thawed galangal spongy, tea-like in aroma and a bit bitter.¹
Best use for frozen	Curry paste, by Leela’s account; Pailin also accepts it in tom yum.¹²
How long frozen?	Waitrose: up to 2 months, unpeeled and wrapped in foil. No other published figure found.³
Fresh, in the fridge	Leela: almost two weeks in the crisper, wrapped; Waitrose: 2 to 3 weeks.¹³
At room temperature	A Thai study gives fresh galangal a marketable life of 7 days.⁴

Does frozen galangal taste the same?

Here’s where the sources split.

Source	Position on frozen galangal
Leela, SheSimmers¹	Freezing alters taste, aroma and texture “quite a bit.” Thawed, it becomes spongy, tea-like in aroma and a bit bitter. Still usable in a curry paste, but detrimental to a dish like tom yam. She does not recommend freezing.
Pailin Chongchitnant, Hot Thai Kitchen²	In her tom yum recipe: frozen or dried galangal will work as a substitute for fresh.

We’re not going to pick a winner. They aren’t quite answering the same question anyway. Leela is comparing frozen with fresh. Pailin is offering frozen as a fallback when fresh isn’t around, and she’s firm that ginger is no substitute.² In practice, fresh galangal is best where it’s the lead aroma in a clear soup. Frozen makes a reasonable stand-in, and what it loses matters least when it’s pounded into a paste with other strong aromatics. That’s our read of Leela’s advice, though, and we found no test of it.

Freeze it, or keep it fresh?

Galangal doesn’t last long on the counter. A 2022 Thai postharvest study took 7 days as the marketable life of fresh rhizomes at room temperature.⁴

In a home fridge, Leela wraps fresh galangal in a double layer of paper towel and puts it in a plastic bag. She says it stays fresh in the crisper for almost two weeks.¹ Waitrose gives 2 to 3 weeks in the fridge.³ If you’ll use it within that window, the fridge spares you the texture change.

How to freeze galangal

Whole or in chunks. Waitrose wraps unpeeled galangal in foil and freezes it for up to 2 months.³ Cut it into recipe-sized pieces first and you only have to take out what you need.

Thin slices. Leela says galangal can be sliced thin and frozen for longer storage, even though she doesn’t recommend freezing it.¹ Slices are handy for soups like tom yum. Pailin’s recipe uses sliced galangal and notes it’s traditionally left in the soup as garnish. Bag the slices in portions.

Grated or pounded. Galangal is hard and fibrous,⁵ and cooks usually pound or grind it into a paste instead of grating it. Portion the paste into an ice cube tray or into small mounds on a lined baking sheet, freeze, then bag the frozen portions. We didn’t find a published recipe for this, so take it as a suggestion. It fits the one use Leela says frozen galangal is still good for: curry paste.¹

Label and date the bag. USDA’s Food Safety and Inspection Service says food kept constantly at 0°F stays safe and that long freezer storage only affects quality,⁶ so the time limit is about flavor.

Common claims we could not confirm

“Frozen galangal lasts up to nine months.” No source found. The only published figure we found is Waitrose’s 2 months.³
“Galangal has a long shelf life at room temperature.” The Thai storage study used 7 days of marketable life at room temperature as its baseline.⁴
“Leaving the skin on preserves flavor and nutrients.” No source found. Waitrose freezes it unpeeled but doesn’t say why.³
“Thaw for 20 minutes and the skin peels off with a spoon” and “frozen galangal grates more easily.” We found no galangal-specific source. America’s Test Kitchen reports this for ginger (see can you freeze ginger?), but we haven’t assumed it carries over to galangal, which is harder and more fibrous.⁵
