Pork crackling with bok choy (油渣小白菜, yóu zhā xiǎo bái cài) is the kind of unpretentious Hunan home cooking that proves simplicity can be sublime. Cubes of pork fat are slowly rendered until they turn into golden, crispy cracklings (油渣, yóu zhā), then those cracklings are tossed with tender baby bok choy and garlic in their own fragrant pork fat. The cracklings add a deep, savory crunch and a rich porkiness, while the greens stay bright, sweet, and slightly crisp. It is a dish born of frugality — nothing wasted, the rendered fat used for cooking and the crispy bits celebrated as a treat. One bite and you understand why this humble plate is a comfort-food classic across Hunan dinner tables.
In old Hunan, as in much of rural China, pork fat was precious. Families would buy chunks of pure fatback and render it slowly in a wok to make lard for everyday cooking. The byproduct — the crispy golden cracklings called 油渣 (yóu zhā) — was never thrown away. Children would snatch them hot from the wok, sprinkled with salt, as a rare treat. Cooks learned that these cracklings, tossed with whatever fresh greens were in the garden, turned a plain vegetable dish into something luxurious. Baby bok choy, with its sweet stems and tender leaves, is the classic partner. This dish is a edible memory of a time when nothing was wasted and even rendered fat was celebrated — a philosophy that still defines honest Hunan home cooking today.
In Pork Crackling with Bok Choy, the wok must be smoking hot so the ingredients sear instantly, locking in moisture while developing the smoky wok hei (breath of the wok) that defines Hunan stir-fry. What sets this apart is the dried red chilies that provide a different, deeper heat than fresh ones. In Hunan, this dish is more than sustenance — it is a reflection of the region's love for bold, unapologetic flavor.
Ingredients
Use pork fatback for the best cracklings; leaf lard works too. Baby bok choy should be small and fresh with crisp white stems.

- 400 g baby bok choy, washed and halved
- 5 garlic cloves, sliced
- 1 tsp ginger, minced

Cooking & Finishing
- Render the pork cracklings. Place the pork fatback cubes in a cold wok with a splash of water. Turn the heat to low and let the fat render slowly — the water prevents the fat from burning at the start. After about 6 to 8 minutes, the cubes will shrink, turn golden, and float in their own clear lard. They are done when they are crisp and light brown. Fish them out with a slotted spoon and drain on paper towels. Keep about 2 tablespoons of the rendered lard in the wok and reserve the rest for other cooking. The cracklings should be crunchy but not hard as stone — drain them just before they look fully done, as they crisp further as they cool.
- Prep the bok choy. While the fat renders, wash the baby bok choy thoroughly — grit hides between the stems. Cut them in half lengthwise if they are small, or into quarters if larger. Drain well in a colander. Wet greens will splatter when they hit the hot fat. Slice the garlic and mince the ginger. Have everything ready because the stir-fry moves fast.
- Flavor the oil. Heat the wok with the reserved pork lard over medium heat. Add the dried chilies if using and let them sizzle for 10 seconds to release their heat into the fat. Add the sliced garlic and minced ginger. Stir for 15 to 20 seconds until fragrant but not browned — garlic that burns in pork fat turns bitter quickly. The oil should now smell rich, garlicky, and gently spicy.
- Stir-fry the bok choy. Turn the heat up to high. Add the bok choy and toss vigorously for 1 to 2 minutes. The greens will wilt slightly and the stems will turn glossy and bright. Keep them moving so they cook evenly without scorching. Add the salt, sugar, and light soy sauce around the edge of the wok. Toss for another 30 seconds. The bok choy should be just tender — still with a little bite in the stems, never soggy.
- Add cracklings and serve. Return the crispy pork cracklings to the wok and toss with the greens for 20 seconds — just long enough to warm them and coat them in the sauce, but not so long that they lose their crunch. Add the scallion sections, give one final toss, and turn off the heat. Serve immediately. The contrast between the crisp, rich cracklings and the sweet, fresh greens is best when the dish is piping hot and the cracklings are still crunchy.
- Start the fat in cold water. It renders evenly without burning and gives lighter, crispier cracklings.
- Drain greens completely. Wet bok choy splatters and steams instead of stir-frying.
- Add cracklings last. Toss them just briefly so they stay crunchy — overcooking makes them tough.
- High heat, fast hands. Bok choy needs a minute or two max to stay bright and crisp.
Variations
Like most Hunan home cooking, this dish welcomes small adjustments to suit your taste and pantry.
With cabbage

Frequently Asked Questions
- Wok not hot enough — the oil should be shimmering but not smoking before you add ingredients.
- Overcrowding the wok — cook in batches if needed; too much food at once causes steaming instead of stir-frying.
- Cutting ingredients unevenly — uniform pieces ensure everything cooks at the same rate.
- Adding sauce too early — let the ingredients sear first, then add sauce in the final 30 seconds.
Serve immediately with steamed white rice — the dish should still be sizzling when it reaches the table. A simple soup like egg drop soup or tomato egg soup provides a cooling contrast. For a full Hunan spread, add one cold appetizer and one vegetable dish.
What Makes It Hunan
Pork Crackling with Bok Choy is a quintessential Hunan dish that showcases the bold, unapologetic flavors of Xiang cuisine. Unlike Sichuan's numbing-spicy heat, Hunan cooking relies on dry, direct spiciness from fresh and dried chilies, complemented by the deep umami of fermented ingredients like duojiao (chopped salted chilies) and douchi (fermented black beans).
In Hunan kitchens, pork is treated with reverence — whether smoked into larou (cured pork belly), braised slowly like this version, or stir-fried with fresh chilies. The province's mastery of pork cookery comes from centuries of preserving meat through smoking, salting, and fermenting, techniques born of humid southern winters and refined into high cuisine.
Whatever the technique, the goal is the same: clean, layered flavors with a clear throughline of chili heat and the savory depth that only slow building — through fermentation, smoking, or patient braising — can produce.
This recipe represents the Hunan preparation. Many Chinese-American restaurant versions of Hunan dishes add extra sugar, use pre-made sauces, or deep-fry ingredients that are traditionally stir-fried. The key difference is that Hunan cooking uses fresh whole chilies, fermented condiments like duojiao and douchi, and high-heat wok techniques — not thick, sweet sauces.
