Do you have to boil broccoli before stir-frying? Whilst you don't have to, I prefer to. A quick boil in hot water, or a steam, will softened up the stem a little, making it tender before adding to the hot wok. This way the stem will be a little more tender, but the broccoli will retain some crunch.
Broccoli isn't like most pan fried vegetables: it needs a steam! Because broccoli is rather tough, it cooks best when you add a little water a few minutes in. This lets it get tender without the pan becoming very dry.
Blanching broccoli is not necessary for stir frying, especially if you cut the florets small. If the florets are big they may take longer to cook in the wok, which may mean your chicken (or other veggies) gets overcooked.
Blanch vegetables before stir-fry
Blanching destroys the enzymes that turn green veggies brown and mushy over time or with cooking. This makes it perfect for preparing ingredients for recipes that rely on the bright green color.
Steamed broccoli may be one of the healthiest ways to cook broccoli because it's quick and nutrients and vitamins won't be lost in the cooking water, as can be the case with boiled broccoli.
If you add too many ingredients at once, they will overlap and steam, rather than sauté, making them rubbery or soggy. "Cook each ingredient separately," advises Martinez. Not only does this ensure that you won't pile too much in the pan at once, but it will also account for different cooking times.
To blanch broccoli, start by bringing a large pot of water to a boil. Once boiling, submerge chopped broccoli florets into the pot. It does not take long to blanch broccoli – only about 30-60 seconds, so keep an eye out for when the color changes from dull green to bright green.
Start with the hard vegetables like carrots and broccoli. Stir and scoop vegetables to the side to make room for more. Then add the softer vegetables, like sliced mushrooms and zucchini. Pour in some stock or water and always keep the veggies moving in the pan.
Many woks also come with a lid, handy for slow braising as it prevents the liquid from evaporating. But for a stir-fry, you want to cook the dish quickly in a small amount of oil with the lid off so the steam escapes.
Tips & Notes: Chinese restaurants blanch the broccoli first because blanching cooks the broccoli faster and make the last step of stir frying and finishing much faster. The sauce also ends up cleaner in flavor.
Broccoli — florets and stems — must be blanched for effective freezing. If you freeze it raw, you'll wind up with bitter, drab green, shriveled stems. Blanching preserves the bright green color and tasty flavor.
Cook, stirring constantly, until browned around the edges, about 2 minutes. Add 2 tablespoons of water to steam the broccoli, and cook, stirring constantly, until tender, about 2 minutes more. Push the broccoli to the edges of the pan, forming an empty well in the center.
Cooking (Or Not Cooking) Broccoli To Protect Its Nutritional Riches : The Salt Cooking broccoli too long destroys the beneficial enzyme that breaks down chemicals into cancer fighters. The best way to eat it is raw or steamed for just two to three minutes, a nutrition expert says.
Blanching stops enzyme actions which otherwise cause loss of flavor, color and texture. In addition, blanching removes some surface dirt and microorganisms, brightens color and helps slow vitamin losses. It also wilts greens and softens some vegetables (broccoli, asparagus) and makes them easier to pack.
Pour about an inch of water into a skillet or wok and bring it to a boil over medium-high heat. Put the broccoli florets in a steamer basket and season with salt. Set the steamer basket over boiling water and cook until the broccoli is crisp-tender, 8 to 10 minutes depending on the size of the florets.
Stir-fry onions first, then add hard vegetables such as carrot and broccoli. Quick-cooking vegetables, such as snow peas, leafy greens and bean sprouts, should be added towards the end of cooking. If using vegies that have a combination of both textures, such as gai laan, add the stems first and the leaves later.
Use fresh vegetables if you have them (peppers, sugar snap peas, sliced bok choy, asparagus, mushrooms or broccoli), but frozen stir fry mix works just as well.
The solution? It's simple: you have to reduce cooking time in order to preserve the colour. Whether in water, steamed or stir-fried, cooking green vegetables for 5-7 minutes will protect the chlorophyll against acidic damage.
Stir-frying and stir-frying/boiling, the two most popular methods for most homemade dishes in China, cause great losses of chlorophyll, soluble protein, soluble sugar, vitamin C, and glucosinolates, but the steaming method appears the best in retention of the nutrients in cooking broccoli.
Cook the vegetables in boiling water 1 to 5 minutes (see below for example times). When you notice the color of whatever veggie you're cooking becomes bright and vibrant, that means it's done.
Step-by-step instructions. Bring 4 quarts water and 2 teaspoons salt to a rapid boil; fill a large bowl with cold water and ice. Lower the broccoli florets into the boiling water and cook for 2 to 3 minutes. The broccoli should be bright green and tender-crisp.
An alternative way of blanching small amounts of vegetables is to use a microwave oven. Microwave blanching may not be as effective as water blanching, but avoiding a hot pot of boiling water may be more important to you.
