 Ingredients

• 1 lb (450g) flank steak or sirloin, thinly sliced against the grain

• 1 large onion, sliced

• 2 cloves garlic, minced

• 2 tablespoons soy sauce

• 1 tablespoon oyster sauce (optional but adds depth)

• 1 tablespoon cornstarch (for tenderizing the beef)

• 2 tablespoons vegetable oil

• Salt and black pepper to taste

• Optional: green onions (sliced, for garnish)

Step-by-Step Instructions

1. Marinate the Beef

In a bowl, combine the beef slices, soy sauce, oyster sauce, cornstarch, and a pinch of pepper. Let it sit for at least 15 minutes to tenderize and soak up flavor.

2. Prepare the Stir Fry Base

Heat 1 tablespoon of oil in a wok or large skillet over high heat. Add the onion slices and garlic, and stir-fry for 2-3 minutes until fragrant and slightly golden. Remove and set aside.

3. Cook the Beef

In the same wok, add another tablespoon of oil. Sear the marinated beef in batches to avoid overcrowding. Cook for about 1-2 minutes per side until browned.

4. Combine Everything

Return the onions and garlic to the wok. Stir everything together, adjusting the seasoning with a bit more soy sauce or salt if needed. Cook for another 2 minutes until heated through.

5. Garnish and Serve

Top with sliced green onions if desired and serve immediately with steamed rice or noodles.
