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.

The art of not wasting — pork fat as treasure

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.

Ingredients

Use pork fatback for the best cracklings; leaf lard works too. Baby bok choy should be small and fresh with crisp white stems.

  • 150 g pork fatback, cut into 1 cm cubes
  • 400 g baby bok choy, washed and halved
  • 5 garlic cloves, sliced
  • 1 tsp ginger, minced
  • 2 dried red chilies (optional)
  • 1/2 tsp salt
  • 1 tsp sugar
  • 1 tbsp light soy sauce
  • 1 tbsp cooking oil (only if needed)
  • 2 scallions, cut into sections

Step-by-Step Instructions

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
Secrets to crispy cracklings and bright greens
  • 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

Replace the bok choy with shredded napa cabbage or flat cabbage for a sweeter, crunchier version popular in winter.

Spicy cracklings snack

Skip the greens and toss the hot cracklings with salt and chili powder for an irresistible bar snack, eaten with cold beer.

Frequently Asked Questions

What exactly are pork cracklings (yóu zhā)?
Yóu zhā (油渣) are the crispy golden bits left after you slowly render pork fat into lard. As the fat melts away, the remaining connective tissue and meat fibers fry in their own oil until they become light, crunchy, and intensely porky. They are essentially fresh, warm pork rinds — but softer and richer than the packaged kind. In Hunan they are treasured both as a snack and as an ingredient. Nothing about them is wasteful: the rendered lard is used for cooking, and the cracklings add texture and flavor to vegetable dishes, noodles, and even steamed buns.
Is this dish very unhealthy because of the pork fat?
It is rich, yes — the cracklings and lard are mostly fat. But a serving is modest, and the baby bok choy adds fiber, vitamins, and bulk, so the dish is more balanced than it sounds. If you want a lighter version, use less fatback (100 g), drain off more lard after rendering, and add a teaspoon of vegetable oil for the stir-fry instead. You can also bake the cracklings in the oven instead of pan-rendering them to reduce the fat slightly. Enjoyed occasionally as part of a vegetable-rich meal, it is a perfectly reasonable treat.
Can I use store-bought pork rinds instead?
You can, but the result is different. Store-bought pork rinds (chicharrones) are puffed and very light, and they will soak up sauce and go soft instantly. Fresh-rendered yóu zhā are denser and hold some crunch even when tossed with greens. If you only have pork rinds, add them at the very last second and do not let them sit in the sauce. For the authentic texture, it is best to render your own from fatback — it takes only 8 minutes and the lard you get is a wonderful bonus for cooking.
What greens work besides baby bok choy?
Almost any tender, slightly sweet green works. Good substitutes include choy sum, Shanghai bok choy, spinach (add it last, it wilts in seconds), water spinach (空心菜), or even broccoli rabe for a more bitter edge. Avoid very watery greens like iceberg lettuce, which will flood the wok. The key is to pick something with some structure in the stem so it stands up to the rich cracklings. Cabbage is a classic winter alternative that Hunan families love.
