Ingredients List

• 500 g flank steak or sirloin, thinly sliced against the grain
• 2 tablespoons vegetable oil, divided
• 2 medium onions, thinly sliced
• 1 red bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 3 cloves garlic, finely minced
• 1 teaspoon freshly ground black pepper
• 1 tablespoon cornstarch
• ¼ cup beef stock
• 2 tablespoons soy sauce
• 1 tablespoon oyster sauce
• 1 teaspoon Worcestershire sauce
• ½ teaspoon sugar
• Salt, to taste
• Optional garnish: spring onions or cracked black pepper

Step-by-Step Instructions

Prepare the Beef Properly

Pat the steak dry to remove surface moisture. Slice thinly against the grain to shorten muscle fibers, ensuring tenderness. Lightly season with salt and half of the black pepper, then toss with cornstarch.

Build the Sauce Base

In a bowl, whisk together beef stock, soy sauce, oyster sauce, Worcestershire sauce, sugar, and remaining black pepper. Set aside so the flavors can integrate.

Sear the Steak

Heat 1 tablespoon oil in a heavy skillet or wok over high heat. Add the steak in a single layer and sear quickly, about 60 seconds per side, until lightly browned. Remove immediately and reserve.

Cook the Onions and Peppers

Lower heat slightly and add the remaining oil. Add onions and cook for 3–4 minutes until softened and lightly caramelized. Add bell peppers and cook until just tender, maintaining a slight bite.

Finish the Dish

Stir in garlic and cook briefly until fragrant. Return the steak to the pan, pour in the sauce, and toss to coat evenly. Simmer for 2–3 minutes until the sauce thickens and the beef is just cooked through.

Serve at Peak Flavor

Remove from heat while the sauce is glossy and the steak remains tender. Garnish if desired and serve immediately.
