A herb-forward Northern Thai (Lanna) stew of pork or beef simmered with its offal in a thin, brothy gravy bound by a Northern chili paste — no coconut milk. Lemongrass, galangal, garlic, shallot, dried chili and shrimp paste are pounded into the base, the meat and innards stewed until tender, and a large fistful of fresh dill thrown in off the heat. The result is brothy and aromatic, faintly bitter from the greens and offal, eaten by the ladle with sticky rice. In Chiang Rai the broth is often darkened with a little blood.
A village dish of the Lanna north and the Isan northeast, its invention unrecorded — kaeng om is everyday country cooking built on a pounded chili paste rather than a chef's or court recipe. The Northern Thai form is documented in the Chiang Mai University Lanna food archive as a guest-and-festival dish of pork with offal; what marks it everywhere is the closing handful of dill. The North and the Isan northeast split on the seasoning that carries it: the Lanna version is bound with shrimp paste pounded into the chili paste, while Isan cooks reach instead for fermented fish. The name 'om' is a Thai term for a curry combining several meats and vegetables; its exact word-origin is not securely documented.
A thin, glistening broth the colour of weak tea — or murkier where blood is added — with chunks of pork and soft slivers of offal, the whole bowl steaming green from a raft of dill. The first spoonful is savoury and herbal, lemongrass and galangal up front, then a low bitterness from the innards and greens and a mild dried-chili warmth underneath. The dill is bracing and almost medicinal, very different from the perfumed thickness of a coconut curry.
With no coconut milk to carry it, the flavour rides entirely on the pounded paste and the broth, so the meat and offal are simmered long enough to soften the connective tissue and lend the thin liquid body and a faint organ-bitterness. The dill is the load-bearing move and is added at the very end off the heat: its aroma comes from volatile carvone and other terpenes that flash off fast, so a minute too long on the boil and the herb turns drab and grassy rather than green and bright. Shrimp paste (or, in Isan, fermented fish) is pounded into the chili paste and cooked through, its glutamates deepening the savour; turmeric tints the broth and a splash of blood, where used, darkens it and adds a mineral richness.
Variations
Named by the protein: kaeng om mu (pork with offal) and kaeng om nuea (beef) are the Northern staples, while kaeng om gai uses chicken for a quicker, lighter bowl. The North-vs-Isan split is the main fork — Lanna binds the paste with shrimp paste, Isan with pla ra fermented fish and often a heavier hand of dill and lemongrass-basil. Do not confuse it with Or Lam, the Luang Prabang stew it resembles: Or Lam is defined by tongue-numbing sa-kaan pepper-vine wood and is thickened to a paste with roasted ground sticky rice, whereas kaeng om uses no sa-kaan and stays a thin, dill-led broth. It is also distinct from Isan tom saap (a clear lemongrass-lime hot-sour offal soup, no chili paste) and Central kaeng pa (jungle curry built on krachai and green peppercorn).

How it's made
6 steps · 30 min
- 115 min
Pound dried chilies, shallot, garlic, lemongrass, galangal, turmeric and shrimp paste into a coarse Northern chili paste in a mortar.
- 210 min
Clean the pork (or beef) and its offal well, then cut the meat and innards into bite-size chunks.
- 325 min
Bring a pot of water or light bone stock to a boil and simmer the meat and offal until just tender, skimming the foam.
- 412 min
Stir the pounded chili paste into the pot and simmer until the broth is fragrant and the raw smell is gone; season with fish sauce.
Watch outSimmer the pounded paste in until the broth's fragrant and the raw smell is gone — with no coconut milk, the flavor rides entirely on this paste and the broth.
- 56 min
Add kaffir lime leaves and any firm vegetables and cook a few minutes more, adding a splash of blood here if using.
- 63 min
Throw in the lemongrass-basil and a large handful of fresh dill, stir once, take the pot off the heat and serve hot with sticky rice.
Watch outThrow the dill in, stir once, and pull off the heat immediately — its aroma flashes off fast, and a minute too long turns it drab and grassy.
