Start by marinating the thinly sliced steak in Shaoxing wine and soy sauce. Sprinkle it with cornstarch and toss until it’s well-coated. This simple marinade infuses the beef with flavor and ensures crispy edges when cooking.
Heat vegetable oil in your wok or skillet until shimmering. Fry the beef in batches, ensuring the pieces don’t overlap. This prevents steaming and guarantees a delightful crispiness. Once done, set it aside on a plate.
Mix the remaining soy sauce, cornstarch slurry, brown sugar, and water in a bowl. Heat a touch of oil in your skillet, then sauté ginger, garlic, and the white parts of the green onions. Add your sauce mixture and cook until it thickens slightly.
Toss the cooked beef back into the pan along with the green onion tops and dried chili peppers. Mix until everything is evenly coated in the glossy, flavorful sauce. Simmer for 2-3 minutes, then serve immediately.
