Galangal (Lengkuas)

Sharp, piney ginger relative essential to Thai curry pastes, tom yum and Indonesian rendang.

Galangal is a knobby rhizome related to ginger but firmer and woodier, with a sharp, citrusy, pine-like flavor. It is fundamental to Southeast Asian cooking, pounded into Thai curry pastes, simmered in tom yum soup and used in Indonesian rendang. Fresh galangal is sliced or pounded; dried slices and powder are milder substitutes.

Galangal is a rhizome from the Zingiberaceae family, related to ginger but with a distinctly different character. Where ginger offers warm sweetness, galangal brings sharp, piney, citrusy notes with a hint of camphor—a flavor that reads as more medicinal and intense. Native to Indonesia and Southeast Asia, it has been a cornerstone of regional cooking for centuries, particularly in Thai, Indonesian, Malaysian, Lao, and Vietnamese cuisines. Unlike ginger, galangal is almost never eaten raw or as a snack; it is always cooked—pounded into aromatic pastes, simmered in soups and braises, or sliced and removed before serving, much like a bay leaf. The rhizome's dense, woody texture makes it difficult to work with by hand, but its contribution to Southeast Asian cooking is irreplaceable, lending depth and signature aromatics that no other ingredient quite replicates.

The Indonesian name Lengkuas is often used interchangeably with galangal in recipe contexts, though technically it refers to the lesser galangal variety specifically. In commerce, you will encounter both greater and lesser galangal, plus occasional confusion with cassumunar ginger, which is a distinct but related species commonly used in Thai cooking. The woody texture means thin slices become brittle and can lodge in teeth when cooked; thick slices or pre-grated paste are more practical for most applications. Freezing whole or sliced galangal preserves it for months with no detectable flavor loss, making it far more practical than relying on fresh stock, which only keeps a few weeks refrigerated.

Types & varieties

Greater Galangal (Alpinia galanga)

Larger rhizomes with pale buff or reddish skin; more common commercially; lighter flavor with citrus and pine notes

Lesser Galangal (Alpinia officinarum)

Smaller, darker, more intensely colored interior; stronger, more medicinal flavor; prized in Indonesian cooking (Lengkuas)

Cassumunar Ginger (Zingiber cassumunar)

Sometimes labeled as galangal; distinct species with reddish-orange skin; common in Thai cuisine

Working with Fresh Galangal

Fresh galangal's fibrous, woody structure runs lengthwise, which means standard grating techniques often produce uneven results—long stringy pieces rather than clean pulp. The most effective approach is to slice the rhizome thinly against the grain, then use a heavy microplane or rasp grater held at a steep angle. Alternatively, bruise thick slices with a cleaver or meat mallet before adding them to braises or soups; this ruptures the cell walls and releases aromatic oils more effectively than raw slices alone. For curry pastes, many Thai cooks toast the sliced galangal briefly in a dry pan before pounding—this deepens the flavor and reduces the raw, medicinal edge.

  • Slice against the grain, not parallel to it
  • Use a microplane or rasp grater, not a standard box grater
  • Bruise thick slices before adding to long-cooking dishes
  • Toast sliced galangal briefly for deeper flavor in pastes

When to Remove It

Because galangal is always cooked and never eaten, timing and removal matter. In dishes that simmer for 30 minutes or more, add thick slices and remove them before serving—just as you would a bay leaf. In shorter-cooking preparations like stir-fries or raw pastes, smaller cuts are acceptable and often desirable since they integrate more fully into the dish. Thin shards become brittle when cooked, and they can lodge uncomfortably in teeth; err toward larger, manageable pieces that you can easily fish out.

  • Remove thick slices from long-cooking dishes before serving
  • Thin shards become brittle and unpleasant
  • Larger pieces are easier to locate and remove

Common uses

Thai red and green curry pastes (often toasted and pounded raw in paste)Tom yum and tom kha gai soupsIndonesian rendang and other braised meat dishesMalaysian satay marinadesSambals and relishesStir-fried dishes and curries across Southeast AsiaFlavoring for coconut milk-based dishesSliced thick and added to braises, then removed before serving (like a bay leaf)

Tips & pitfalls

  • Slice against the grain or use a heavy microplane—the fibers run lengthwise and resist standard grating
  • Bruise fresh slices by bashing with a cleaver or mallet before cooking to release aromatic oils
  • If a dish simmers long (30+ minutes), slice galangal thick enough to remove easily; thin shards become brittle and unpleasant
  • Frozen galangal grates easily and keeps for months with no flavor loss
  • Taste the cut root before using—quality varies; it should smell intensely aromatic, not muted
  • Do not substitute 1:1 with ginger in dishes where galangal is called for; ginger lacks the piney, medicinal intensity
  • Store galangal in the freezer and grate directly from frozen for maximum convenience
  • Toast dry slices briefly before adding to curry paste for deeper, less raw flavor
