Pad Tua Fak Yao (ผัดถั่วฝักยาว)

The Stir-Fry That Must Crunch

ผัดถั่วฝักยาว is the answer to the cheapest question in a Thai kitchen: what is in the fridge and needs eating. Aroifin frames the dish exactly that way — long beans are the everyday vegetable, the one that turns up in curries, soups and stir-fries. Its ten-minute version is the definitive one: Wongnai's Nickktwf times the whole thing at five minutes prep, five minutes cooking, and the beans go in last, stir-fried only until the colour changes, so they stay crisp — TrueID's egg version makes the same point in its own words: อย่าผัดนาน, don't stir long, the beans must keep their fresh crunch and smell.

The house signature of the classic version is the oil. Wongnai's recipe fries the garlic in sesame oil and is explicit about it: "เมนูนี้ตั้งใจจะให้ได้กลิ่นหอมของน้ำมันงา" — this dish is deliberately built on the aroma of sesame oil. From there it is pork and pantry seasoning: oyster sauce, seasoning sauce, a spoon of sugar, a splash of sweet dark soy for colour.

The other school swaps plain oil for red curry paste. Kapook's version — 968,897 reads — fries a spoon or two of แกงเผ็ด paste until fragrant, adds sliced pork, then the beans, then holy basil and ten shredded kaffir lime leaves. TrueID's 345Pink works the paste harder: fried until แตกมัน, until the oil splits out of it, a splash of water, palm sugar to cut the heat. Both versions crown the plate with a fried egg.

The Recipe (home version, from Wongnai — Nickktwf)

The curry-paste version (Kapook): 300 g pork, sliced or minced; 1–2 tbsp red curry paste; long beans; 10 shredded kaffir lime leaves; holy basil if liked; sugar and fish sauce to season. The egg version (TrueID, 345Pink): long beans and 2 eggs, seasoned with 3 tbsp fish sauce, 1 tbsp light soy and ½ tsp MSG — the egg is fried first, the beans folded in until just glossy.

The Method

1. The sesame garlic. Fry the garlic in the sesame oil until fragrant — the sesame aroma is the dish's signature, not an afterthought.
2. The pork. Add the minced pork and stir-fry until cooked through.
3. The seasoning. Season with the sugar, seasoning sauce, pork seasoning powder and oyster sauce, adding a little sweet dark soy for colour. Taste and adjust.
4. The beans, last. Add the long beans and the red chillies and stir-fry only until the colour changes. The beans must still crunch — the moment they soften, the dish is over.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Stewing the beans. Every Thai source agrees: the beans go in last and come out while they still crunch. A long western simmer turns the dish into soft green mush.
• Skipping the sesame oil. The classic version is built on sesame-oil garlic. Neutral oil makes a perfectly fine stir-fry that no longer tastes like the dish.
• Confusing it with a side salad. Pad tua fak yao is a main-dish stir-fry eaten over rice, often crowned with a fried egg — not a plated vegetable side.
• Under-seasoning. The Thai build layers oyster sauce, seasoning sauce, seasoning powder, sugar and dark soy. A splash of soy sauce alone leaves it flat.
• Using snap or French beans as a "substitute" with a long cook. The yardlong bean's crisp texture is the point; substitutes need the same short, hot finish, not a western braise.

UK Ingredient Notes

• Yardlong beans: at Thai, Vietnamese and Chinese grocers, often labelled long beans or snake beans; snap beans work as a substitute with the same short finish.
• Sesame oil: toasted (dark) sesame oil from any supermarket — this is the version the recipe wants.
• Seasoning sauce and seasoning powder: Thai brands (e.g. Maggi-style sauce and Knorr-style powder) at Asian grocers; if unavailable, a dash more fish sauce and a pinch of MSG carry it.
• Red jinda chillies: Thai grocers; bird's-eye is hotter, use fewer.
• For the curry-paste version, ready-made แกงเผ็ด paste is at every Thai grocer.
