Water & Steam

Steam

Cook in rising vapor to keep color, nutrients, and shape intact

Steaming cooks food in the vapor above simmering water, never letting it touch the liquid. It preserves color, texture, and nutrients better than boiling — ideal for vegetables, dumplings, and fish. Keep the lid on and the water topped up so the steam stays steady.

Steaming cooks food in the hot vapor rising off simmering water, without the food ever touching the liquid. Because nothing is submerged, steaming preserves color, texture, shape, and water-soluble nutrients far better than boiling, which leaches them into the water. It's the gentle, clean choice for vegetables, dumplings, fish, custards, and rice, and it cooks surprisingly fast — vapor carries a lot of heat. The whole technique comes down to keeping a steady supply of steam: a tight lid, water that doesn't run dry, and food held above the waterline so it bathes in vapor rather than boils.

Difficulty: Easy

Types & varieties

Bamboo steaming

Stacked baskets over a wok — classic for dim sum, and the wood wicks away drips.

En papillote

Food sealed in parchment or foil steams in its own juices in the oven.

Pressure steaming

Steaming under pressure in a sealed cooker for speed (overlaps pressure-cooking).

How to do it

1
Set up the steamer
Add an inch or two of water to a pot and fit a basket or rack so food sits above, not in, the liquid.
2
Bring water to a boil
Get a strong, steady steam going before the food goes in so it cooks from the first moment.
3
Arrange in a single layer
Lay food in one even layer (line bamboo with parchment or cabbage for dumplings) so vapor reaches everything.
4
Cover and don't peek
Clap on a tight lid; lifting it releases the steam and drops the temperature, stretching the cook time.
5
Watch the water level
On longer steams, keep a kettle of hot water handy to top up before the pot runs dry and scorches.
6
Check and serve
Test for a tender-crisp bite or just-opaque fish, then serve at once — steamed food cools fast.

Why steaming keeps nutrients and color

When you boil vegetables, water-soluble vitamins (C and the B group) and pigments leach out into the cooking water and get poured down the drain. Steaming never immerses the food, so those compounds largely stay put — studies consistently find steamed vegetables retain more vitamin C than boiled ones. The vapor also cooks gently and evenly without the mechanical battering of a boil, which is why steamed broccoli stays vivid green and a steamed fish fillet stays intact and silky rather than waterlogged.

Tips & pitfalls

Don't let food touch the water — it should sit fully above the line so it steams, not boils.
Line bamboo baskets with parchment, lettuce, or cabbage leaves so dumplings don't stick.
Add aromatics (ginger, lemongrass, citrus) to the water to gently perfume the food.
Keep extra boiling water ready to top up during long steams so the pot never runs dry.
