Ingredients List

• 2 tablespoons vegetable oil, divided
• 1 red bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 yellow bell pepper, thinly sliced
• 1 medium onion, thinly sliced
• 3 cloves garlic, finely minced
• 1 teaspoon freshly ground black pepper
• 1 tablespoon cornstarch
• ¼ cup beef broth
• 2 tablespoons soy sauce
• 1 tablespoon oyster sauce
• 1 teaspoon Worcestershire sauce
• ½ teaspoon sugar
• Salt, to taste
• Optional garnish: sliced spring onions or sesame seeds

Step-by-Step Instructions

Slice and Season the Beef

Pat the steak dry and slice it thinly against the grain to ensure tenderness. Lightly season with salt and half of the black pepper, then toss with cornstarch to protect the meat during high-heat cooking.

Prepare the Stir Fry Sauce

In a small bowl, combine beef broth, soy sauce, oyster sauce, Worcestershire sauce, sugar, and remaining black pepper. Mix until smooth and set aside.

Sear the Steak

Heat 1 tablespoon oil in a wok or large skillet over high heat. Add the steak in a single layer and sear quickly, about 1 minute per side, until just browned. Remove immediately and set aside.

Stir Fry the Vegetables

Add the remaining oil to the pan. Cook onions and bell peppers over medium-high heat for 3–4 minutes, stirring frequently, until crisp-tender. Add garlic and cook briefly until aromatic.

Combine and Finish

Return the steak to the pan. Pour in the prepared sauce and toss everything together. Cook for 2–3 minutes until the sauce thickens slightly and coats the beef and vegetables evenly.

Serve Hot

Remove from heat once the steak is tender and glossy. Garnish if desired and serve immediately.
