Beef and Mushroom Stir Fry (口蘑炒牛肉)

Beef and mushroom stir fry features juicy beef slices and tender mushrooms tossed in a rich, glossy brown sauce with a hint of pepper and butter. It’s a quick and comforting dish that’s perfect for your weeknight dinner.
When you’re craving a savory, satisfying dinner that comes together in under 30 minutes, beef and mushroom stir fry is a reliable go-to. Mushrooms soak up the savory sauce and release their earthy essence, while the thinly sliced beef sears quickly for maximum tenderness and flavor. The sauce is a classic brown sauce made with soy sauce, oyster sauce and aromatics with additional black pepper, giving the dish a rich, slightly sweet depth with a kick. Top it on steamed rice to soak up the sauce, and you’ll have a hearty meal in no time.
