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.

Mise en place

Make sure you have everything cut and prepared before starting the stir fry. Have these ingredients close to your stove:

Sliced mushrooms: I used white button mushrooms. You can also use brown mushrooms.
Aromatics: Scallion and garlic
Marinated beef: The Shaoxing wine and oyster sauce add flavor. Baking soda tenderizes the meat, and the cornstarch gives it a silky mouthfeel.
Mixed brown sauce: It’s a basic brown sauce with chicken stock, soy sauce, oyster sauce and sugar. I added black pepper to give the dish a kick. The cornstarch thickens the sauce.
Butter and oil: I added butter to the cooking oil, to make the stir fry extra rich.

How to cook beef and mushroom stir fry

Sear the beef. The key is to sear the beef until just cooked, then transfer it to a plate. It ensures the mushrooms cook properly and the meat is not overcooked.

Cook the mushrooms until tender and the liquid evaporates.

Pour in the sauce, add back the beef and add the scallion. Cook and mix until the sauce thickens.

Finish up the dish by adding sauce and scallion

That’s it! Now you can serve it over steamed rice or noodles. It’s so hearty and delicious.

Tips for Success

Slice the beef thinly and against the grain for the most tender texture.
Use high heat and work quickly—stir frying should be fast to preserve the freshness and texture of each ingredient.
Don’t overcrowd the pan. If you want to add other veggies to the pan, make sure to reduce the amount of mushrooms to avoid cooking too many ingredients at a time.
