Sai Oua: Northern Lao Herbal Pork Sausage
Sai Oua: Northern Lao Herbal Pork Sausage
At markets across Luang Prabang, sai oua grills over charcoal from early morning — plump pork sausages that perfume the whole street with lemongrass, galangal and chilli long before you see them. Slice one open and the inside is green-flecked with herbs, juicy, coarse and deeply fragrant. This is northern Laos' signature sausage, and once you have tasted it fresh off the grill with sticky rice, no plain sausage ever quite measures up again.
A sausage defined by its herbs
What makes sai oua different is not the pork — it is everything pounded in with it. Where a Western sausage leans on salt, pepper and smoke, sai oua is built like a Lao herb paste wrapped in meat. Lemongrass, galangal, kaffir lime leaf, shallots, garlic, chillies and fresh herbs go in in generous handfuls, so every bite tastes bright and green as well as rich and savoury. The texture is deliberately coarse: the pork is chopped or coarsely ground, never turned into a smooth paste, so the sausage stays hearty and satisfying.
Lao sai oua and Thai sai ua
Visitors who know Chiang Mai's famous sai ua will recognise the family resemblance — northern Thailand and northern Laos share deep roots across the old Lan Xang and Lanna kingdoms. The Lao version from Luang Prabang tends to push the herbs even further, with dill and coriander stirred through and a good hit of padaek or fish sauce for depth. It is often a little more rustic, a little greener, and made to be eaten the Lao way: torn by hand, with sticky rice and jeow, not in a bun.
What goes in it
- Pork shoulder, coarsely ground, with a good proportion of fat — about 20–30% keeps it juicy
- Lemongrass, galangal and kaffir lime leaf, pounded or minced very fine
- Shallots, garlic and dried or fresh chillies, for warmth rather than fierceness
- Fresh dill and coriander, chopped and folded through generously
- Padaek or fish sauce and a little salt, to season deeply
- A spoonful of cooked sticky rice or rice flour in some family recipes, to bind and keep it tender
- Natural pork casings, soaked and rinsed — or shape into patties if casings are hard to find
How it tastes
The first bite is juicy pork, then the herbs arrive all at once — citrusy lemongrass, warm galangal, lime leaf and dill — followed by a slow chilli warmth and the savoury depth of fermented fish underneath. Grilling adds the final note: the casing crisps and blisters a little over charcoal, the fat bastes the herbs inside, and the whole sausage turns smoky at the edges. It is rich but never heavy, because the herbs keep cutting through.
Simple home recipe (makes about 8 sausages)
- Pound or finely mince 2 stalks of lemongrass (tender part only), a thumb of galangal, 4 kaffir lime leaves (centre stem removed), 4 shallots, 5 garlic cloves and 3–5 chillies to a rough paste. If using a food processor, pulse in short bursts — you want texture, not a purée.
- In a large bowl, mix 800g coarsely ground pork shoulder with the herb paste, 1 tablespoon of padaek or fish sauce, 1 teaspoon of salt, 1 teaspoon of sugar, a large handful of chopped dill and a handful of chopped coriander. Mix well with your hands until the mixture feels sticky. Fry a teaspoonful to check the seasoning and adjust.
- Rest the mixture, covered, in the fridge for at least 1 hour, or overnight for the best flavour.
- Stuff into soaked natural casings and twist into links about 12–15cm long, pricking any air pockets with a needle. Alternatively, shape firmly into thick patties or roll into short logs in cling film and chill until firm.
- Grill slowly over medium charcoal or under a moderate grill (broiler) for 15–20 minutes, turning often, until cooked through, deep golden and lightly blistered. Rest 5 minutes — the juices need a moment to settle.
- Slice on the diagonal into thick coins so the green herbs show, and serve hot.
How to eat it
In Luang Prabang, sai oua is served with sticky rice, jaew bong or another jeow for dipping, and a plate of raw or blanched vegetables and herbs — cucumber, long beans, cabbage and lettuce — to refresh the palate between bites. Leftovers, if there ever are any, are excellent sliced and fried up with rice the next day. Make a double batch if you can: sai oua freezes well uncooked, and a freezer stocked with it is a very good thing to come home to.
