When steaming vegetables, a strainer or steaming container placed over boiling water is used; the vegetables are cooked without direct contact with the water, only until softened by the water vapor. The answer to how vegetables are steamed lies in this simple setup. When vegetables are cooked this way in steam, both their color and nutritional value are preserved better than boiling. This method is especially preferred for vegetables like broccoli, carrots, and zucchini.
When vegetables are boiled in water, some of the vitamins inside them can leach into the water and be lost. Since steaming ensures the vegetable doesn't come into direct contact with water, this loss is significantly reduced. Also, since steam temperature affects the vegetable somewhat more gently than boiling water, its texture stays firmer and the risk of it becoming mushy decreases. Adding a small amount of olive oil or lemon juice to the vegetables after cooking both enhances the flavor and can contribute to some vitamins being better utilized.
What Is the Correct Method for Steaming Vegetables?
The following order should be followed for vegetables to cook properly in steam.
- Vegetables should be cut into roughly equal sizes.
- A small amount of water that won't touch the vegetables should be put in the pot and brought to a boil.
- Vegetables should be placed in a steaming strainer or container and the lid closed.
- Vegetables should be cooked for 4-8 minutes depending on the type.
- Cooked vegetables should be taken out of the strainer immediately and prepared for serving.
What Are the Mistakes Made When Steaming?
Some mistakes during steaming negatively affect the vegetables' consistency.
- Putting too much water in the pot so the vegetables come into contact with the water produces a result similar to boiling.
- Opening the lid frequently causes the steam to escape and prolongs the cooking time.
- Leaving vegetables in steam longer than necessary causes their textures to soften and become mushy.
- Cooking vegetables of different sizes at the same time causes some pieces to be undercooked and others overcooked.
How Are Steamed Vegetables Flavored?
Steamed vegetables naturally have a mild taste, so the flavoring step after cooking is important. Adding a small amount of olive oil, fresh parsley, or lemon juice brings out the vegetable's taste. Adding garlic and spices to the vegetable after cooking rather than to the cooking water ensures both that the vegetable's own taste is preserved and that the spice's aroma is felt more vividly.
Which Vegetables Are More Suited to Steaming?
Broccoli, carrots, asparagus, and zucchini are especially suited to steaming; these vegetables preserve their color and firm texture during contact with steam. Leafy vegetables cook in a shorter time, so their steaming time should be limited to just a few minutes. Root vegetables, on the other hand, require a somewhat longer steaming time due to their thicker structure; cutting these vegetables into equal sizes helps the cooking time be balanced.
If there's no steaming container, a metal strainer can serve the same function; it's enough to place the strainer's base at the mouth of the pot so it doesn't touch the boiling water. If more than one type of vegetable is being steamed at the same time, placing the vegetables that need a longer time at the bottom and those that cook quickly on top gives a more balanced result.
Steaming vegetables is possible with proper cutting, little water, and a short cooking time. With this method, when vegetables are steamed, both color and texture are preserved and nutrient loss is also reduced. Using the correct strainer and closed lid ensures the vegetables that come to the table are firm and flavorful.
