This Chinese-American restaurant staple pairs crispy fried noodles with chicken and vegetables stir-fried in a thick brown sauce. This family-friendly dinner couldn't be easier to make.
Whisk 3 tablespoons soy sauce into cornstarch in a small bowl. Whisk in 2 tablespoons wine, sugar, and broth. Season chicken with salt and remaining 2 teaspoons soy sauce and 1 tablespoon wine.
Heat a 10-inch cast-iron skillet over medium-high and add 1/4 cup oil; heat until shimmering. Add noodles and flatten to an even layer. Reduce heat to medium and cook 1 minute. Add 1/3 cup water and cook, pushing edges in with a spatula to shape into a more compact disc, until golden brown and the entire thing holds together like a mat, 4 to 5 minutes more. Carefully slide a spatula underneath and flip over. Drizzle 2 tablespoons oil around edges of pan. Cook until crisp on the second side, 2 to 4 minutes. Transfer to serving plate.
Return pan to medium high-heat, add chicken, and cook until golden brown on one side, 1 to 2 minutes. Toss and cook until almost cooked through, about 1 minute more. Remove from pan. To the pan, add 2 tablespoons oil and mushrooms and cook until tender, about 2 minutes. Add carrots and Chinese broccoli. Toss 1 minute. Add ginger and garlic and cook until fragrant, about 1 minute. Stir sauce to recombine, then add to pan and bring to a boil. Add chicken and toss to combine. Stir in sprouts and sesame oil. Serve over crispy noodles.
Hong Kong chow mein noodles are sold in the refrigerated case at Asian markets. They are "precooked" and therefore do not need to be boiled ahead of time.
