Thick udon noodles are wok-fried with vegetables and a savory Chinese-style sauce. This hearty, family-friendly dish is quick to make and can be boosted with chicken or shrimp for added protein.
Prepare all vegetables: shred cabbage, julienne carrot, slice shiitake mushrooms, and cut scallions into 2-inch pieces. Mince the garlic.
Mix soy sauce, oyster sauce, dark soy sauce, and sugar in a small bowl to form the sauce base.
Heat 2 tbsp vegetable oil in a large wok over medium-high heat until shimmering. Add the garlic and stir-fry for 10 seconds until fragrant but not browned.
Increase heat to high, add cabbage, carrot, and mushrooms. Stir-fry for 2–3 minutes, tossing constantly to prevent burning, until just tender.
Add fresh udon noodles and the mixed sauce. Toss quickly to coat noodles and veggies evenly, adding 2–4 tbsp water if needed to loosen noodles.
Stir-fry everything over high heat for 2–3 more minutes until the noodles are glossy and heated through. Finish with scallions and drizzle of sesame oil. Serve immediately.
