Prep:
- Marinate the chicken: Thinly slice the chicken breasts into bite-sized pieces and add to a medium bowl. Add the white pepper, kosher salt, low sodium light soy sauce and sesame oil. Mix well to coat, set aside.
- Make the sauce: Whisk together the Worcestershire sauce, oyster sauce, low sodium light soy sauce, mirin, dark soy sauce, dashi powder and sesame oil in a small bowl or measuring cup (for easier pouring) until combined well.
- Prepare all the fresh ingredients: Prepare the yellow onion, spring onion, carrot, mushrooms, Chinese cabbage, garlic and fresh red chilies as indicated in the ‘ingredients’ section.
Chicken Yaki Udon Noodles Stir Fry:
- Prepare the noodles: Bring a small pot of water to a boil. Lower the heat to medium-low and place the udon noodle cakes in the pot of hot water. Use tongs to hold onto the noodle cakes and gently shake until the noodle strands have separated and are tender – about 1-2 minutes. Drain into a colander and run cold water on the noodles to prevent sticking and halt the cooking process. (If using frozen or dried udon noodles, prepare according to package instructions.)
- Cook the chicken: Heat 1 teaspoon peanut oil in a large nonstick wok (or heavy bottomed deep skillet/frying pan) over high heat. Add the marinated chicken and immediately spread the pieces out in the wok. Allow to sear for 30-40 seconds, then flip the pieces and sear the other side for another 30 seconds. Stir-fry for a minute or until just cooked. Transfer to a clean bowl and set aside.
- Stir-fry the veggies and aromatics: Heat the remaining 1 tablespoon of peanut oil in the wok over high heat. Add the yellow onion, spring onion white and light green parts, mushrooms and carrots and stir-fry for 30-40 seconds or until starting to soften and change color but are still crisp. Add the garlic and red chilies and stir-fry for 20-30 seconds until fragrant.
- Add the cabbage: Add the Chinese cabbage and stir-fry until slightly wilted but it still retains some crunch.
- Add the chicken, noodles and sauce: Add the chicken and toss briefly to combine. Then add the noodles and pour the sauce on top. Stir-fry and mix until everything is evenly coated in the sauce.
- Season and toss through the spring onion: Season with black pepper and toss through the spring onion dark green parts. Switch off the heat.
- To Serve: Divide evenly in bowls or on plates and serve immediately with desired toppings.
