Crispy pork belly stir-fried hard with Chinese kale (kana / gai lan), garlic, fresh chili, and oyster sauce, the cut belly tossed in only at the end so its crackling skin stays crisp against the dark-green, faintly bitter kale. It is one of Thailand's most popular over-rice plates, sold at rice-and-curry shops and stir-fry stalls everywhere, usually with a runny fried egg and a saucer of chili-fish-sauce (prik nam pla) alongside. Savory, garlicky, and a little hot, it is built around the contrast of shattering pork skin and snapping greens.
The dish marries two Chinese-Thai elements: crispy pork belly (moo krob), a roast-pork tradition from southern-Chinese cooking sold at Bangkok's Chinatown stalls beside roast duck and barbecued pork, and the stir-fried-greens-with-oyster-sauce technique that came with Cantonese and Teochew cooks. Chinese kale (Brassica oleracea var. alboglabra) is itself a Chinese vegetable naturalized into Thai cooking. There is no single inventor; pad kana moo krob is generic rice-shop and street food, the everyday partner to a plate of jasmine rice, and one of the default "point-and-eat" stir-fries (aahaan taam sang) at any Thai stall.
The first thing is the skin — a hard, audible crack giving way to a thin layer of soft fat and tender meat underneath. Against it, the kale stems snap and the leaves carry a clean, mustardy bitterness that cuts the pork's richness. Garlic and oyster sauce coat everything in glossy savory-salt, fresh chili pricks through, and a squeeze of the chili-fish-sauce on the side sharpens each bite. It is a study in contrast — crisp against crunchy, fat against bitter, salty against the plain sweetness of rice. A soggy pork skin is the one true failure.
The crackling is the engineering challenge: the belly is simmered or steamed until the meat is tender, then the skin is dried thoroughly — air-dried or refrigerated uncovered — pricked all over, salted, and either deep-fried or roasted at high heat. As the surface moisture flashes off, the collagen-and-fat skin puffs and shatters into glass-like crackling; any trapped moisture steams instead and leaves it leathery. In the stir-fry, the pork goes in last and is tossed only briefly so the skin meets minimal sauce and stays crisp. The kale is cooked hot and fast to keep its color and snap, and a splash of water or stock hitting the hot wok flashes to steam that cooks the stems through without stewing them. Oyster sauce, with its concentrated glutamates, and a little sugar balance the green bitterness and the pork's fat.
Variations
The same stir-fry is built on roast duck (pad kana pet yang), barbecued pork (moo daeng), salted fish (kana pla khem), or shrimp; firm tofu and mushrooms make a meat-free version. Some cooks lean savory-only while others add a touch of sugar, dark soy, or yellow bean sauce. The pork itself flexes — some buy ready-made crispy belly from a Chinatown roast stall, others fry it fresh — and the chili level runs from a single sliced chili to a fistful for a fiery rendition.

How it's made
6 steps · 30 min
- 155 min
Simmer the pork belly until tender, dry the skin thoroughly, prick and salt it, then deep-fry or roast at high heat until the skin blisters into crackling; cool and cut into bite-size pieces.
Watch outDry the belly skin thoroughly before it goes in the fat; any trapped moisture steams instead of blistering and leaves you with leathery skin instead of glass-crisp crackling.
- 24 min
Separate Chinese kale stems from leaves and cut into lengths; slice garlic and fresh chili.
- 32 min
Stir oyster sauce, a splash of soy, a little sugar, and water into a small bowl of sauce.
- 43 min
Heat oil in a wok, fry the garlic and chili until fragrant, then add the kale stems and a splash of water to steam them briefly.
- 52 min
Add the leaves and the sauce, tossing over high heat until the greens are bright and just tender.
- 61 min
Fold in the crispy pork last, toss once or twice to coat, and serve over rice with a fried egg and chili-fish-sauce.
Watch outAdd the crispy pork last and toss only once or twice; the less sauce touches the skin, the longer that crackling stays crisp.
