Every Chinese dinner needs one green thing on the table. This is that green thing. Bok choy, garlic, oil, salt, four minutes from fridge to plate, about a dollar fifty for a plate that feeds three.

It is the least glamorous recipe on this site and probably the one I cook most often. A rich braise or a bowl of fried rice needs something crisp and slightly bitter next to it, and this is the answer that requires no planning at all.

What you need #

• Bok choy, about a pound. Baby bok choy is the tender kind sold in bunches of small heads. Large bok choy works too and just needs the stems separated from the leaves.
• Garlic, four or five cloves, sliced. Not minced. Slices go golden and stay sweet. Minced garlic goes from raw to burnt in about fifteen seconds in a hot pan.
• Neutral oil, a tablespoon.
• Salt. That is genuinely it.

Optional, in the order I would add them: a splash of Shaoxing wine, a small drizzle of oyster sauce, a few drops of sesame oil at the end, a pinch of sugar.

The steps #

1. Wash it properly. Bok choy hides grit at the base of the stems. Split the heads lengthwise, fan the leaves apart under running water, and rub the base with your thumb. Sandy bok choy ruins a meal and there is no fixing it after it is cooked.
2. Dry it. Shake it hard in a colander, or spin it. Wet vegetables steam instead of sear, and steamed bok choy is the grey watery version you are trying to avoid.
3. Get the pan properly hot. Medium-high to high, oil in, wait until it shimmers.
4. Garlic first, briefly. Ten to fifteen seconds, just until it smells like garlic and the edges start to color. Do not walk away.
5. Stems in, then leaves. With large bok choy, add the thick white stems, cook a minute, then add the leafy parts. With baby bok choy just put the whole thing in cut side down.
6. Sprinkle salt over it, add two tablespoons of water, and immediately cover the pan for sixty to ninety seconds. The water flashes to steam and cooks the stems through while the leaves stay bright.
7. Lid off for thirty more seconds to let the water cook off. Plate it. Done.

Total time on the stove is under four minutes. The washing takes longer than the cooking.

How to tell it is right #

The leaves should be dark green and glossy, not olive. The stems should be translucent at the edges and still snap when you bite them. If the whole thing has slumped into a soft pile and there is a puddle of green water on the plate, it went about ninety seconds too long.

Pull it off the heat while it still looks slightly underdone. It keeps cooking on the plate.

Swaps and substitutions #

This exact method handles yu choy, gai lan (Chinese broccoli), spinach, napa cabbage, and even green beans if you extend the covered-steam step by a minute or two. Gai lan is my favorite of the group and slightly more bitter.

For the version most restaurants serve, add a teaspoon of oyster sauce with the water in step six. It makes the dish savory and glossy. Vegetarian oyster sauce made from mushrooms is widely available and just as good here.

For a garlic sauce version, double the garlic and add a splash of Shaoxing wine plus a small cornstarch slurry at the end so it clings.

You can also blanch and dress instead: boil the bok choy for ninety seconds, drain, and pour hot oil with garlic and soy sauce over it. Cleaner flavor, less pan work, and it can be served at room temperature.

A pinch of dried chili flakes with the garlic is good. Restrained, not a chili dish.

Tips #

Sliced garlic, not minced. I said it above and I am saying it again, because burnt garlic is the number one way this dish fails.

Do not crowd the pan. A pound of bok choy in a small skillet steams in its own moisture. Use the biggest pan you own, or cook it in two batches.

Salt at the pan, not the plate. Salting during the steam step seasons the stems from the inside. Salting at the end just seasons the surface.

Buy it the day you cook it, or the day before. Bok choy goes limp and yellow fast. It is not a vegetable that keeps.

The stems are the good part. People trim them off. Do not. They have a sweetness and a crunch the leaves do not.

What it costs #

Bok choy at a Chinese grocery in San Francisco runs about a dollar fifty a pound, sometimes less on a good week. At a mainstream supermarket the same bunch is three to four dollars. That gap illustrates the wider point about grocery shopping in Chinatown: the produce is the same produce, and the difference is which store you walked into.

This is the side dish for basically everything on this site. Put it next to red braised pork belly to cut the richness, or beside mapo tofu and rice for a full weeknight dinner under five dollars a person.
