Bamboo Steamer

Stackable woven baskets that steam dumplings, buns, and sticky rice over a wok.

A bamboo steamer is a set of stackable woven baskets with a lid, set over a wok or pot of simmering water to steam food gently. It is essential for dim sum like dumplings and buns, and for steaming fish, vegetables, and sticky rice. The bamboo absorbs excess condensation so it doesn't drip back onto the food, and multiple tiers let you cook several items at once.

A bamboo steamer is a stackable set of shallow, woven baskets with a loose-fitting lid, designed to perch over a wok or pot of simmering water. The bamboo wicks away excess condensation and lends a faint, earthy fragrance, while the slatted base lets steam rise freely through every tier. Because the baskets are lightweight and interchangeable, a cook can run two or three levels at once, finishing fish, dumplings, and a vegetable side in the same pan.

Bamboo steamers have been the everyday steaming vessel in Chinese kitchens for centuries, and they remain preferred over metal inserts for many tasks because the wood never gets screamingly hot and will not react with delicate foods. They are inexpensive, fold flat for storage, and are replaced rather than repaired once the weave weakens — most cooks treat them as semi-disposable, retiring a set when the slats darken or begin to shed.

Types & varieties

10-inch two-tier

The workhorse size; fits a 12-inch wok and holds 8–10 soup dumplings per tier.

10-inch three-tier

For larger meals or cooking several components simultaneously.

8-inch single or stacked

Small-format for two-person portions or a whole small fish.

12- and 14-inch banquet size

Needs a correspondingly wide wok; used for whole chickens, large fish, party quantities.

Replacement tiers

Sold as single baskets so a two-tier set can be expanded to three or four.

Care and lifespan

Bamboo steamers need almost no upkeep beyond a hot rinse and a full air-dry. After each use, tip out any food residue, run the baskets and lid under the hottest tap water the bamboo can handle, and stand them on a rack until completely dry before stacking. Never submerge the steamer for long periods and never put it in a dishwasher — the soak swells the weave and rots the stitching. A well-used steamer darkens with age, picking up a patina of steam and starch; that is normal and even welcome. Replace the set when the slats start to splinter, the stitching unravels, or the base no longer sits flat. Because the cost is low, most cooks keep a backup on hand so a worn-out set can be swapped in mid-service.

Tips & pitfalls

Line the base with parchment (pierced with holes), napa cabbage leaves, or lettuce to keep small foods from sticking and to catch drips.
Keep the water at a hard simmer, not a rolling boil — too vigorous and the pan boils dry or splashes up into the bottom tier.
Stack from the top down: foods that cook fastest go up top, the longest-cooking item sits nearest the steam source.
Lift and wipe the inside of the lid between batches; drips falling back into the basket make buns and dumplings soggy.
Rinse with hot water only — soap is absorbed by the bamboo and later taints the food.
Raise the basket off the bottom of the wok with a small metal trivet, a ring of tied scallions, or a crumpled sheet of aluminum foil so the base sits above the waterline.
For a stronger aroma, tuck a few slices of fresh ginger or a small handful of tea leaves into the water beneath the basket.
