Directions

I start by cooking the rice according to package instructions and keep it warm.
I heat oil in a large skillet or wok over medium-high heat.
I add the sliced beef and stir-fry quickly until just browned, then remove it from the pan.
In the same pan, I add a little more oil if needed and sauté the onions until softened.
I add the mushrooms and cook until they release their moisture and begin to brown.
I stir in the garlic (and ginger if I’m using it) and cook briefly until fragrant.
I return the beef to the pan.
I whisk together soy sauce, oyster sauce, broth, and cornstarch, then pour it into the skillet.
I stir everything together and let it simmer for a few minutes until the sauce thickens and coats the beef and vegetables.
I season with black pepper, taste, and adjust as needed.
I serve the stir-fry hot over cooked rice.

Servings and timing

This recipe serves about 4 people and takes roughly 25–30 minutes from start to finish. It’s fast, filling, and perfect for weeknight dinners.

Variations

Sometimes I add bell peppers, snap peas, or broccoli for extra color and crunch. I’ve also used chicken or tofu instead of beef with great results. When I want a little heat, I add chili flakes or a splash of chili sauce to the stir-fry.

Storage/reheating

I store leftovers in an airtight container in the fridge for up to 3 days. To reheat, I warm the stir-fry gently in a skillet or microwave until heated through. If the sauce thickens too much, I add a splash of water or broth to loosen it. Beef, Onion & Mushroom Stir-Fry Over Rice
