Beef Onion Stir-fry

This Beef Onion Stir-fry features thinly sliced flank steak marinated with baking soda, cornstarch, oyster sauce, and oil for tender, savory beef. Stir-fried with sliced onion wedges and a sauce combining soy sauces, ketchup, oyster sauce, sugar, and sesame oil, the dish balances rich umami flavors with the mild sweetness and slight bite of lightly blistered onions. It's a quick-cooking, hearty stir-fry perfect over rice.

Description

The recipe starts by marinating thin slices of flank steak in a mixture including baking soda and cornstarch to tenderize and add a slight velvety texture. The beef is seared in a hot wok until mostly cooked, then removed. Onions are quickly stir-fried until blistered but not fully softened, contributing sharpness and crunch.

A savory sauce made from multiple soy sauces, ketchup, oyster sauce, sugar, and sesame oil is simmered briefly in the wok before the beef and onions return to the pan, allowing the flavors to coat the ingredients evenly. The combination of the tender beef and caramelized onions creates a flavorful dish with contrast in texture and taste.

Serve this stir-fry over steamed rice for a satisfying meal that comes together quickly with simple ingredients and straightforward technique.
