Instructions
Gather Ingredients
Prepare all ingredients ahead of time for a smooth cooking process. Slice the beef against the grain for tenderness. Trim the broccoli and keep only the florets.
Make the Slurry
Mix potato starch with water until fully dissolved. Set it aside and stir again just before using.
Sear the Beef
Heat oil in a hot wok. Add beef in a single layer and sear without stirring for about 2 minutes. Stir and cook for another 1–2 minutes. Season with salt and pepper.
Add minced garlic and ginger; stir until fragrant. Pour soy sauce around the edges of the wok for even seasoning. Stir for another 30 seconds, then remove the beef from the wok.
Cook Broccoli and Green Onions
Add more oil if needed. Stir-fry broccoli until it turns bright green. Season with salt and pepper, then add a splash of cooking wine. Cook for 2–3 minutes.
Return Beef and Add Slurry
Add the beef back to the wok along with sliced green onions.
Stir the slurry and pour it in. If the broccoli isn’t fully cooked, add a splash of water. Cook until the sauce thickens. Add a handful of green onions 30 seconds before turning off the heat.
Finish with Sesame Seeds
Transfer everything to a serving plate. Sprinkle toasted sesame seeds on top and serve hot.

Notes
Slice Against the Grain: Cutting flank steak across the muscle fibers helps it stay tender and easier to chew.
Use a Hot Pan: Preheat your wok or skillet until very hot before adding oil and ingredients to get a proper sear.
Don’t Overcook Broccoli: Stir frequently and cook just until the broccoli turns bright green and is crisp-tender.
Toast Sesame Seeds: Heat sesame seeds in a dry pan until golden and fragrant to enhance their flavor.
Use Fresh Slurry: Potato starch settles quickly—stir the slurry just before adding to ensure even thickening.
