Tender beef strips stir-fried with mushrooms and aromatics in a savory brown sauce. This quick and easy beef mushroom stir-fry is ready in 30 minutes in one pan! A delicious main dish that's both family-friendly, better-than-takeout, and great for busy weeknights or meal prep.
Slice the beef on an angle against the grain into ¼-inch-thick strips. Transfer to a large bowl.
Toss the sliced beef with the marinade ingredients as listed above and let sit for 15-20 minutes.
In a small bowl, mix the sauce ingredients as listed above and set aside.
Heat vegetable oil in a large pan over medium heat. Sear the beef until cooked through and slightly browned at the edges, about 4-5 minutes. Remove and set aside.
Sauté onions and mushrooms until just softened, about 2 minutes. Add the sauce and simmer until slightly thickened, about 30 seconds.
Return the beef to the pan along with green onions. Toss to coat evenly, about 30 seconds. Remove from heat and serve immediately.
