This beef chow fun is a classic Cantonese stir-fry with tender marinated beef, smoky wok-seared rice noodles, crisp bean sprouts, and savory soy sauce flavor. It cooks quickly once everything is prepped, making it perfect for a restaurant-style noodle dinner at home.
Slice the flank steak thinly against the grain. In a bowl, mix the beef with water, baking soda, cornstarch, oyster sauce, 1 teaspoon Shaoxing wine, and soy sauce. Let it marinate for at least 30 minutes while you prepare the noodles and vegetables.
Prepare the rice noodles. If using fresh rice noodle sheets, cut them into strips about 1 inch wide. If the noodles are firm or stuck together, briefly blanch them in boiling water for about 30 seconds, then cool in ice water and drain very well. If using dried wide rice noodles, soak until pliable according to the package directions, then drain.
Heat a wok or large skillet over high heat until very hot. Add 1 1/2 tablespoons vegetable oil and swirl to coat. Add the marinated beef in a single layer and sear just until browned and mostly cooked through, then transfer it to a plate.
Add the remaining 1 1/2 tablespoons vegetable oil to the wok. Add the ginger slices and stir-fry for about 15 seconds to perfume the oil, then add the scallions and toss briefly.
Add the drained rice noodles and spread them across the hot surface of the wok. Let them sear for a few seconds, then toss gently. Splash the remaining 1 teaspoon Shaoxing wine around the edge of the wok so it sizzles and evaporates.
Add the dark soy sauce, sesame oil, sugar, and seared beef. Toss with a lifting motion to coat the noodles evenly without breaking them, scraping the bottom of the wok as needed to prevent sticking.
Taste and season with salt and white pepper. Add the bean sprouts and stir-fry just until they soften slightly but still stay crisp. Serve immediately while the noodles are hot and glossy.
Use fresh wide rice noodles if possible; they give beef chow fun its signature chewy texture. Keep the wok very hot and avoid overcrowding, or the noodles will steam instead of sear. If using dried noodles, soak only until flexible, not mushy, and drain thoroughly before stir-frying.
