First things first, slice that flank steak thinly against the grain. This is crucial for tender beef; seriously, don't skip this step! Then, toss the beef with a tablespoon of soy sauce and a teaspoon of cornstarch. Let it hang out for a bit while you get the broccoli ready. For the broccoli, I usually steam or blanch it for just 2-3 minutes until it's bright green and still has a bite. This is where I learned from my overcooked mistake—we want crisp-tender, not mush!

In a small bowl, whisk together the remaining soy sauce, oyster sauce, beef broth, brown sugar, sesame oil, and the rest of the cornstarch. Make sure that cornstarch is fully dissolved, or you’ll end up with a clumpy sauce, and nobody wants that! Give it a good whisk until everything is smooth and ready to go. This sauce is the magic that transforms humble ingredients into a delicious Chinese Beef and Broccoli feast, so take your time here.

Heat a large skillet or wok over medium-high heat with a bit of oil. Once it's shimmering, add your marinated beef in a single layer. Don't overcrowd the pan, or the beef will steam instead of sear. You want a nice brown crust on it, so work in batches if you need to. I always smell that amazing savory aroma when the beef hits the hot pan—it's the best! Cook for just 2-3 minutes per side until beautifully browned.

Once the beef is seared, remove it from the pan and set it aside. Add a little more oil if needed, then toss in your minced garlic and grated ginger. Oh, the smell! Sauté for about 30 seconds until they’re fragrant; you’ll know because your kitchen will start smelling like a dream. Be careful not to burn them, as burned garlic is just bitter and sad.

Now, pour your prepared sauce into the pan with the aromatics. Bring it to a gentle simmer, stirring constantly. You'll see it start to thicken beautifully thanks to that cornstarch. This is where the sauce really comes alive, developing that glossy, rich texture that coats everything so perfectly. It’s so satisfying to watch it transform!

Add the seared beef and the blanched broccoli back into the pan with the thickened sauce. Toss everything gently to ensure every piece of beef and every floret of broccoli is coated in that glorious, glossy sauce. Let it warm through for just a minute or two. The vibrant green of the broccoli against the dark, rich sauce is just so inviting. You've just made your very own delicious Chinese Beef and Broccoli!
