Nam Phrik Kaeng Khiao Wan (Green Curry Paste)

This traditional Thai green curry paste builds layers of flavor from scratch, starting with dry-roasting whole coriander and cumin seeds in a wok until they’re fragrant and toasty. That five minutes of toasting deepens the spice flavor in a way raw seeds simply can’t match.

Fresh green chilies are the backbone here, giving the paste its signature heat and vivid color. The lemongrass and coriander root add that bright, citrusy complexity that separates a real green curry paste from the jarred stuff sitting on grocery shelves.

Blend everything to a fine texture. You want a smooth, pounded-style paste, not a chunky salsa. Add the shrimp paste last so it distributes evenly without overpowering during the blending.

Kitchen Tips

• Keep the wok heat low when toasting the seeds. They burn fast and bitter seeds will ruin the whole batch.
• If you can’t find coriander root, use the stems from a bunch of cilantro. More stems, less leaf, for the closest substitute.
• Store in a clean glass jar with a thin layer of oil on top to prevent oxidation. It keeps 3 to 4 months refrigerated.
• Freeze in ice cube trays for single-use portions that last even longer.

Variations

• Omit the shrimp paste and add extra salt plus a splash of soy sauce for a vegetarian version.
• Increase the green chilies for a blistering paste, or halve them for a milder curry base.
