Ingredients
beef sirloin, thinly sliced
200g
mung bean sprouts
300g
garlic cloves, minced
3
light soy sauce
2 tablespoons
dark soy sauce
1 tablespoon
oyster sauce
1 tablespoon
cornstarch
1 tablespoon
Sichuan peppercorn powder
1/2 teaspoon
ground black pepper
1/4 teaspoon
cooking wine
2 tablespoons
vegetable oil
3 tablespoons
fresh chives, chopped
2 stalks
Instructions
1
Marinate the beef
Place the sliced beef in a bowl. Add 1 tablespoon of light soy sauce, the cornstarch, a pinch of black pepper, and 1 tablespoon of oil. Mix well until the beef is evenly coated. Let it sit for 10 minutes to tenderize.
2
Sear the beef
Heat a wok or large skillet over high heat. Add 2 tablespoons of oil and swirl to coat. Add the Sichuan peppercorn powder and stir for a few seconds until fragrant. Add the marinated beef and spread it out in a single layer. Cook without stirring for 1 minute, then stir-fry until the beef changes color and is nearly cooked through, about 2 minutes total. Remove and set aside.
3
Build the aromatics
In the same wok, add a splash more oil if needed. Toss in the minced garlic and stir-fry for 10 seconds until aromatic. Add the dark soy sauce and cook for another few seconds to develop flavor.
4
Combine and finish
Return the beef to the wok. Add the mung bean sprouts and toss everything together over high heat. Pour the cooking wine in a circle around the edge of the wok. Add the remaining light soy sauce, oyster sauce, and a pinch of black pepper. Stir-fry vigorously for 1-2 minutes until the sprouts are tender-crisp but still have some bite. Toss in the chopped chives, give one final stir, and serve immediately over steamed rice.
