Ingredients
Scale
Beef Marinade
- 1 pound flank steak or sirloin, thinly sliced against the grain
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon hoisin sauce
- 1 teaspoon cornstarch
- 1 teaspoon sesame oil
Stir-Fry
- 2 tablespoons vegetable oil
- 1 large onion, sliced
- 2 cloves garlic, minced
- 1/2 teaspoon ground black pepper
Garnish
- 2 green onions, sliced (for garnish)
Instructions
- Marinate the Beef: In a medium bowl, combine the thinly sliced beef with soy sauce, oyster sauce, hoisin sauce, cornstarch, and sesame oil. Mix thoroughly to coat the beef evenly and let it marinate for at least 15 minutes to absorb the flavors.
- Heat the Oil: Place a large skillet or wok over high heat and add the vegetable oil. Allow it to get hot enough to sear the beef quickly.
- Cook the Beef: Add the marinated beef to the hot pan and stir-fry for 2 to 3 minutes until the beef is browned on the outside but not fully cooked. This short, high-heat cooking seals in juices and flavor. Remove the beef from the pan and set aside.
- Stir-fry Onions and Garlic: In the same pan, add the sliced onion and minced garlic. Stir-fry for 2 to 3 minutes until the onions start to soften but still hold some crispness and the garlic is fragrant.
- Combine and Finish Cooking: Return the partially cooked beef to the pan, sprinkle with ground black pepper, and stir-fry everything together for another 2 to 3 minutes. This step finishes cooking the beef and allows the onions to caramelize slightly, enhancing the dish’s depth of flavor.
- Garnish and Serve: Remove from heat, garnish with sliced green onions, and serve hot. This stir-fry is delicious with steamed rice or your favorite noodles.
Notes
- For easier slicing, partially freeze the beef for about 20 minutes before cutting against the grain.
- Feel free to add additional vegetables such as bell peppers, snow peas, or mushrooms to increase flavor and nutrition.
- Adjust sauce quantities to preference for a saltier or sweeter profile.
- Serve immediately for best texture and freshness.
