Thailand's most iconic green curry: chicken simmered in a vibrant coconut broth of fresh green chilies, kaffir lime, lemongrass, and Thai basil.
Gaeng Keow Wan (ΰΉΰΈΰΈΰΉΰΈΰΈ΅ΰΈ’ΰΈ§ΰΈ«ΰΈ§ΰΈ²ΰΈ) β literally 'sweet green curry' β is Thailand's most internationally recognized curry, yet the version most Westerners encounter bears only a superficial resemblance to authentic Thai green curry. The critical difference is in the paste: genuine Thai green curry paste is built from fresh green bird's eye chilies (not dried), lemongrass, kaffir lime zest and leaves, galangal, garlic, shallots, coriander root, and white pepper, all pounded together in a stone mortar for 20β30 minutes until completely smooth. The color is vivid jade-green, not the dull olive of many commercial pastes. This paste is fried in the coconut cream (the thick fat that rises to the top of unshaken coconut milk) until it splits and blooms, producing a sauce that is aromatic, moderately spicy, and enriched with coconut sweetness in a way that distinguishes Thai cooking from Indian curry. Chicken thighs, Thai eggplant, and a generous handful of fresh Thai basil (horapa) give the dish its structure and herbaceous finish. The name 'sweet' refers not to added sugar but to the inherent sweetness of fresh young green chilies β which, paradoxically, are used in such quantity that the curry is actually hotter than most red curries.
Serves 4
Open coconut milk cans without shaking them. Scoop the thick cream from the top of each can (about 150ml total) into a wok or wide pan. Reserve the remaining coconut milk.
The thick cream on top is the fat that fries the paste. If your cans are thoroughly mixed (no separation), refrigerate them overnight β the cream rises to the top when cold.
Heat the coconut cream over medium-high heat. Stir constantly as it heats β after 3β4 minutes it will bubble, then separate into oily puddles and a drier mass. Add the green curry paste and fry in this cracked coconut cream for 4β5 minutes, stirring vigorously, until the paste deepens in color and becomes very fragrant.
Add chicken pieces and toss to coat in the paste. Cook 2 minutes until the exterior of the chicken turns white.
Pour in remaining coconut milk and stock. Add lemongrass knot, kaffir lime leaves, fish sauce, and palm sugar. Stir and bring to a gentle boil.
Add eggplant. Simmer over medium heat 12β15 minutes until chicken is cooked through and eggplant is tender but still holds its shape.
Pull the pan off the heat. Add Thai basil leaves and sliced red chili. Stir once β the heat from the curry will wilt the basil slightly. Remove the lemongrass. Taste and adjust fish sauce (salt) and palm sugar (sweetness).
Thai basil leaves should go in off-heat and be served immediately β prolonged heat turns them black and muddy-flavored.
Ladle over jasmine rice in deep bowls. Garnish with a few extra basil leaves and a drizzle of fresh coconut cream if desired.
Maesri green curry paste in small cans (not the large Mae Ploy tubs for this dish) has a punchier, more authentic flavor than most UK and US grocery store brands β find it at Asian supermarkets.
Never boil the curry hard after adding coconut milk β vigorous boiling causes the coconut milk to separate into an unappetizing oily surface.
Thai eggplant comes in several varieties: pea eggplant (golf-ball sized, very bitter) and small purple eggplant (milder). Both are correct; use whichever you can find.
Gaeng keow wan goong (prawn): replace chicken with large prawns; reduce cooking time to 4β5 minutes.
Gaeng keow wan tofu: use pressed firm tofu and vegetable stock; add 50g fresh young coconut flesh strips for texture.
Southern Thai green curry: add thin slices of kaffir lime skin and fresh green peppercorns on the stem for an intensely aromatic variant.
Refrigerate up to 3 days; the flavors actually deepen overnight. Reheat gently over medium-low heat β do not boil. Add a splash of coconut milk if the sauce has thickened too much. Cook rice fresh when serving.
Gaeng keow wan is documented in Thai Royal Court cookbooks from the early Rattanakosin period (early 19th century). The dish reflects Thailand's Central Plains cuisine centered on Bangkok. Fresh green chilies, kaffir lime, and galangal β all essential components β have been cultivated in the Chao Phraya river basin for centuries. The dish became internationally known through the global spread of Thai restaurants from the 1970s onward, particularly following Thailand's tourism boom.
The green color comes from fresh green chilies and coriander in the paste β most commercial pastes have less fresh herb content and produce a duller, more yellow-green broth. To intensify the color, add a few extra coriander leaves and a small piece of fresh green chili to the paste when frying it.
Authentic gaeng keow wan is quite spicy β it uses a large volume of fresh green bird's eye chilies. However, most commercial paste is adjusted for Western palates and is moderate. You can control heat by adjusting the amount of paste you use: 2 tbsp is mild-medium, 4 tbsp is hot.
Thai curries use fresh aromatic paste (lemongrass, galangal, fresh chilies) fried in coconut cream as the base; Indian curries use dried spice blends fried in oil or ghee. Thai curries are generally brothier, coconut-forward, and herbaceous; Indian curries are often thicker and more complex in dried spice depth.
Yes β pound 15 fresh green bird's eye chilies, 2 stalks lemongrass (sliced), 3 cm galangal, 4 kaffir lime leaves (zest only), 4 garlic cloves, 4 shallots, 1 tbsp coriander root, and 1 tsp white pepper in a mortar for 20β30 minutes until completely smooth. Homemade paste is significantly more aromatic than commercial versions.
