If using fresh or parboiled chow mein or yakisoba noodles, gently separate them with your fingers. If they are stuck together, quickly rinse under warm water to loosen, then drain very well.
If using dry noodles or spaghetti, cook according to package directions until just al dente (about 1 minute less than usual). Drain, rinse briefly under cold water to stop the cooking, and toss with about 1 teaspoon of oil to prevent clumping. For best stir-fry texture, spread the cooked noodles on a sheet pan to cool slightly while you prep the vegetables.
14-16 oz chow mein noodles
In a small bowl, whisk together the soy sauce, oyster sauce, brown sugar, sesame oil, ground white pepper, and 2–3 tablespoons of water or vegetable broth. Taste and adjust: add a pinch more sugar for sweetness or an extra teaspoon of oyster sauce for more umami. Set aside.
4 tbsp low-sodium soy sauce, 2 tbsp oyster sauce, 2 tsp brown sugar, 1 tsp sesame oil, 1/4 tsp ground white pepper, 2-3 tbsp water or low-sodium vegetable broth
Thinly slice the onion and cabbage, julienne or prepare matchstick carrots, mince the garlic (and ginger, if using), and slice the green onions. Place all vegetables and the sauce near the stove, as stir-fries cook quickly. Heat a large nonstick skillet or wok over medium-high heat. When hot, add the neutral oil and swirl to coat the pan.
2 tbsp neutral oil, 1 medium yellow onion, 2 cups green cabbage, 1 cup carrots, 3 cloves garlic, 2 green onions, 1-2 tsp fresh ginger
Add the sliced onion to the hot pan and cook for 2–3 minutes, stirring often, until softened and just turning golden at the edges. Stir in the garlic (and ginger, if using) and cook for about 30 seconds, just until fragrant. Add the shredded cabbage and carrots. Stir-fry for 3–5 minutes, until the cabbage is wilted but still slightly crisp and the carrots are tender-crisp. If the pan seems dry, add a tablespoon of water to create steam and help soften the vegetables.
1 medium yellow onion, 2 cups green cabbage, 1 cup carrots, 3 cloves garlic, 1-2 tsp fresh ginger, 2-3 tbsp water or low-sodium vegetable broth
Reduce the heat to medium. Add the prepared noodles to the pan with the vegetables. Using tongs or chopsticks, gently toss to combine, lifting and flipping rather than pressing down to avoid breaking the noodles. If any noodles are clumped together, carefully separate them as they warm.
14-16 oz chow mein noodles
Give the sauce a quick stir to redistribute the sugar, then pour it evenly over the noodles and vegetables. Toss for 2–4 minutes, until the noodles are heated through, evenly coated, and glossy light brown, like Panda Express chow mein. If the noodles look dry, add another tablespoon or two of water or broth and continue tossing until everything is well coated.
4 tbsp low-sodium soy sauce, 2 tbsp oyster sauce, 2 tsp brown sugar, 1 tsp sesame oil, 1/4 tsp ground white pepper, 2-3 tbsp water or low-sodium vegetable broth, extra water or broth
Turn off the heat. Stir in the sliced green onions, and if desired, a splash of rice vinegar for brightness and/or a drizzle of chili oil or sriracha for heat. Taste and adjust seasoning with more soy sauce for saltiness, a pinch of sugar for sweetness, a touch more sesame oil for aroma, or pepper for extra bite. Serve hot straight from the skillet or transfer to a serving dish.
