Let’s get started by slicing that flank steak against the grain. Also, mince up your garlic and ginger, and chop your broccoli into bite-sized florets.

Grab a small bowl and whisk together your soy sauce, oyster sauce, brown sugar, cornstarch, and water until it’s all nicely combined. This sauce is going to give our Beef and Broccoli that irresistible flavor!

Heat up 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Toss in your sliced flank steak and let it cook without stirring for a minute or two until one side gets a nice sear.

Then, give it a good stir-fry for another couple of minutes until the beef is browned but still a bit pink in the middle. Once it’s done, set it aside for now.

In that same skillet, add another tablespoon of vegetable oil if needed. Throw in your minced garlic and ginger, and let them sizzle for about half a minute until they start to smell amazing.

Then, toss in your broccoli florets and stir-fry them for a few minutes until they’re bright green and just starting to get tender.

Now, add your cooked beef back into the skillet with the broccoli. Give your sauce a quick stir to make sure everything’s mixed up nicely, then pour it all over the beef and broccoli.

Stir everything together and let it cook for another minute or two until the sauce thickens up and coats everything beautifully.
