Nam Prik Ong (Northern Thai Pork and Tomato Dip)

Nam prik ong belongs to the family of Northern Thai nam prik dips: intensely savoury, chilli-led condiments served for scooping rather than pouring. Here, minced pork and ripe tomatoes are cooked down with shallot, garlic and red curry paste until the tomatoes collapse into a thick, glossy sauce and the pork gives the dip body. Fish sauce brings salt and umami, while palm sugar softens the acidity of the tomatoes without making it sweet. Served warm or at room temperature with fresh vegetables or sticky rice, it works as a punchy appetiser, part of a Thai-style spread, or a practical make-ahead dip that reheats well.

Why this recipe works

  • Built-in depth: Shallot, garlic and curry paste are cooked before the pork and tomatoes go in, giving the dip a more rounded savoury base.
  • Sweet-salty balance: Ripe tomatoes, fish sauce and palm sugar create the characteristic balance of acidity, umami and gentle sweetness.
  • Easy to serve: Its thick, scoopable texture works equally well with raw vegetables, sticky rice or as part of a larger Thai-style spread.

Get the most out of this recipe

Adjust the heat

  • For less heat: Use a milder red curry paste or start with a smaller amount, then adjust once the tomatoes have cooked down.
  • For more heat: Add extra curry paste or a small amount of fresh chilli when frying the aromatics.
  • Keep the flavour balanced: If increasing the chilli, taste at the end and adjust with a little more palm sugar or fish sauce so the heat does not dominate.

Authenticity notes

  • Northern Thai style: Nam prik ong is known for its pork-and-tomato base, softer heat and dip-like texture rather than a loose sauce.
  • Classic accompaniments: Fresh vegetables and sticky rice are natural pairings because they balance the richness and make the dip easy to scoop.

Texture tips

  • For a scoopable finish: Simmer until the tomatoes have broken down and the mixture looks glossy rather than watery.
  • Avoid a loose dip: Keep the pan at a gentle simmer and stir often so excess tomato liquid reduces without the base catching.

Make-ahead tips

  • Make ahead: The dip keeps well in the fridge for up to 3 days and can be reheated gently before serving.
  • Freezer option: Freeze once fully cooled, then defrost overnight in the fridge before reheating until piping hot.
  • Reheat gently: Warm over low heat, stirring regularly, and add a splash of water only if the dip has reduced too much.

  1. Finely chop the shallots and garlic. Roughly chop the tomatoes, keeping any juices.
  2. Heat the vegetable oil in a frying pan over medium heat. Add the shallots and cook for 2 to 3 minutes until softened, then add the garlic and cook for 30 seconds until fragrant.
  3. Stir in the red curry paste and cook for 1 to 2 minutes, stirring constantly, until the oil starts to separate slightly and the paste smells toasted.
  4. Add the minced pork and cook for 6 to 8 minutes, breaking it up with a wooden spoon, until no longer pink and lightly browned in places.
  5. Add the tomatoes, fish sauce and palm sugar, then bring to a gentle simmer. Cook for 15 to 18 minutes, stirring often, until the tomatoes have broken down and the mixture is thick, glossy and scoopable.
  6. Taste and adjust with a little more fish sauce for saltiness or palm sugar for balance, if needed. Let it cool for 2 to 3 minutes so it thickens slightly, then serve warm or at room temperature.

Tips

  • For the best texture, keep the heat at a gentle simmer and stir regularly so the dip reduces without catching on the base of the pan.
  • If serving to vulnerable groups, make sure the pork is cooked through and piping hot before cooling slightly for serving.

Substitutions

  • Replace shallot with white onion for a slightly sharper, less sweet base.
  • Replace palm sugar with light brown sugar for a similar caramel sweetness.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in a sealed container for up to 3 days. Reheat gently in a saucepan over low heat, stirring, until piping hot; add a splash of water only if it has reduced too far. Freeze in an airtight container for up to 2 months and defrost overnight in the fridge before reheating.
