Bottom Line Up Front (Quick Answer):
To make 20-minute beef and broccoli that rivals top Chinese restaurants, thinly slice flank steak against the grain and toss with 1 tablespoon of cornstarch (velveting). Steam broccoli in 3 tablespoons of water directly in the skillet for 2 minutes, then flash-sear the beef over high heat for 90 seconds. Finish by simmering the garlic-ginger soy glaze for 60 seconds until rich, glossy, and clinging to every bite.
Why This Skillet Beats Takeout Every Time
- Flash Cooking: High-heat searing preserves broccoli crunch and prevents the beef from getting tough or steamed.
- Velveting Magic: A 5-minute cornstarch coat locks in interior juices while providing a delicate crust.
- Controlled Sodium & Sugars: Made with pure low-sodium soy sauce, real garlic, and fresh grated ginger without excess oil.

Elena’s Velveting Secret
10-Minute Freezer Slicing Trick:
Flank steak is easiest to slice wafer-thin when it is partially firm. Pop your steak into the freezer for 10 to 15 minutes before cooking. A sharp chef's knife will glide right through across the grain effortlessly!
