I always love a meat-with-veg side dish like this stir fried broccoli & beef. The beef is tender even though I used a modest cut (flank). All I need is some rice to go with the beef, broccoli and the savoury sauce. The cooking time is fast, since both broccoli & beef cook quickly, making this dish ideal for weekdays and busy times.
Cut of beef to use, and how to get tender beef. I usually buy beef flank since it is the most value-for-money cut suitable for stir frying, as compared to ribeye or tenderloin. Despite being a more economical cut, the beef still turned out tender after cooking. The trick is to slice the beef diagonally against the grain, and marinating the beef slices in cornstarch & seasonings for 15-30 minutes. I bought pre-sliced beef from the supermarket, which is a huge convenience, but you can save even more if you slice the beef yourself.
As for the broccoli, I blanch them in boiling water for less than a minute first, so that they don’t have to sit inside the wok for too long. If you want to cook everything in the same wok, fry the beef slices until 3/4 cooked and set them aside on a plate. Add broccoli and stir fry until cooked, then return the beef back to the wok to finish up cooking.
Flank is the most value-for-money cut of beef you can use for this stir-fry: the beef will remain tender after cooking, as long as it is not over-cooked. You can also use more premium cuts such as tenderloin, sirloin, or ribeye.
