Ingredients

For the Beef Marinade

1 lb flank steak, thinly sliced against the grain
2 tablespoons soy sauce
1 tablespoon cornstarch

For Stir-Frying

1 tablespoon vegetable oil
1 large onion, thinly sliced
2 bell peppers (any color), thinly sliced
3 cloves garlic, minced
1 tablespoon fresh ginger, minced

For the Sauce

¼ cup soy sauce
¼ cup beef broth
2 tablespoons oyster sauce
1 tablespoon hoisin sauce
1 teaspoon sugar
½ teaspoon freshly ground black pepper
¼ teaspoon red pepper flakes (optional)

For Serving

Cooked white or jasmine rice
Green onions, chopped (for garnish)

Instructions

1 Marinate the Beef

In a medium bowl, combine the sliced flank steak with 2 tablespoons soy sauce and cornstarch. Mix until all pieces are well coated. Let marinate for 15 minutes.
This step tenderizes the beef and helps create a silky sauce later.

2 Cook the Beef

Heat vegetable oil in a large skillet or wok over medium-high heat.
Add the marinated beef in a single layer and stir-fry for 4–5 minutes, until browned and just cooked through.
Remove the beef from the skillet and set aside.

3 Stir-Fry the Vegetables

In the same skillet, add the sliced onion and bell peppers. Stir-fry for 3–4 minutes until they are tender-crisp and slightly caramelized.

4 Add the Aromatics

Add the minced garlic and ginger to the skillet. Stir-fry for 1–2 minutes until fragrant, being careful not to burn them.

5 Prepare the Sauce

In a small bowl, whisk together soy sauce, beef broth, oyster sauce, hoisin sauce, sugar, black pepper, and red pepper flakes (if using). Mix until fully combined.

6 Combine and Finish

Return the cooked beef to the skillet. Pour the sauce over the beef and vegetables.
Stir well and cook for 2–3 minutes, until the sauce thickens and coats everything evenly.

Cooking Method Explained

This recipe uses a high-heat stir-fry technique, which cooks ingredients quickly while preserving texture and flavor. Marinating the beef with cornstarch helps lock in moisture and gives the sauce a glossy, restaurant-style finish. Cooking the beef and vegetables separately prevents overcooking and ensures the best texture.
