Ingredients

Why this recipe works

High-heat cooking is the secret to a successful stir-fry, as it mimics the intense heat of professional restaurant burners. Searing the flank steak quickly in small batches prevents the meat from crowding the pan, which would cause it to steam instead of brown.

This process locks in the natural juices and creates a deeply caramelized exterior that enhances the overall flavor profile of the dish.

The sauce plays a dual role by seasoning the ingredients and creating a glossy glaze that clings to the beef and vegetables. Using a starch-based thickener like cornstarch allows the liquid to reduce rapidly under high heat, transforming it into a luxurious coat.

This method ensures the vegetables do not become soggy or waterlogged, keeping their colors bright and their textures satisfyingly crisp.

Notes and substitutions

Selecting the right cut of beef is crucial for achieving the tender texture characteristic of great stir-fries. Flank steak is highly recommended due to its lean profile and prominent grain, which makes it easy to slice into tender strips. Always cut the meat against the grain to break up the tough muscle fibers, ensuring a tender chew after cooking.

A heavy-bottomed skillet or a carbon steel wok is the best vessel for this recipe, as they retain heat exceptionally well. Ensure the pan is preheated thoroughly to achieve a beautiful sear on the beef and keep the vegetables crisp-tender. Avoid crowding the pan, which can lower the temperature and cause the ingredients to steam instead of sear.
