Nam Prik Ong is a Chiang Mai tomato-and-pork dip with shrimp paste and prik kee noo chilies.
A Chiang Mai household staple from at least the 19th century, though tomato itself only became cheap in Northern Thai markets after the early 1900s — pre-tomato versions of ong used pickled fruit or sour eggplant for the acid. Eaten as part of a Lanna khantoke (low-table) meal alongside sticky rice and several other nam prik. "Nam prik" means "chili water"; "ong" likely refers to the slow-simmer technique.
A Lanna khantoke relish — pork, dried red chili, shrimp paste, simmered with tomato until the seeds break and pectin sets. The shrimp paste must be dry-fried first or it reads cheesy through the simmer.
A reddish-orange pork-and-tomato relish, soft and chunky, served warm in a small bowl. The base is dried red chili, shallot, garlic, shrimp paste, and tomato — pounded, then simmered with minced pork. Eaten with raw vegetables (cucumber, cabbage, long bean) and pork rinds for dipping. Lighter than its sibling nam prik noom; tomato makes it almost meat-sauce-like, and the heat sits at medium.
The non-obvious move: tomato has to be simmered down hard — 20+ minutes — until the seeds break and the pectin thickens the relish. A short cook leaves it watery and the dip won't cling to a vegetable stick. Shrimp paste must be roasted or dry-fried first; raw shrimp paste reads cheesy-funky in a way that doesn't disappear in the simmer.
Variations
Pre-1900s versions used pickled fruit or sour eggplant before tomato got cheap in Northern markets; the lighter sibling nam prik noom uses charred green chili and no meat; Chiang Mai homes serve it on khantoke trays with cabbage and pork rinds for dipping.

Ingredients
How it's made
6 steps · 45 min
- 15 min
In a krok, pound dried chili, shallots, and kratiem into a paste.
- 28 min
Stir-fry the paste with minced pork until fragrant.
Watch outDry-fry the shrimp paste with the chilies until it smells toasty and nutty, not sharp — raw kapi keeps a cheesy funk that never cooks out in the simmer.
- 35 min
Add cherry tomatoes, allowing them to break down and meld with the meat.
Watch outLet the tomatoes fully collapse — skins split and seeds break loose — before you count it as done; whole chunks mean it'll stay watery.
- 43 min
Stir in kapi and nam pla for depth of flavor.
- 515 min
Simmer until the mixture thickens to a dip consistency.
Watch outSimmer hard past 20 minutes until it mounds on the spoon and stops weeping liquid — a short cook leaves it soupy and it won't cling to a veg stick.
- 62 min
Serve with vegetable crudités and crispy pork cracklings.
