Ingredients

2 large chicken breasts, cut into bite size pieces, 1 pound
8 oz. vermicelli or thin spaghetti
2 tablespoons cornstarch
1/2 cup rice vinegar
1/2 cup reduced sodium soy sauce
1/4 cup sugar
1/4 teaspoon pepper
sesame oil
5 garlic cloves, minced
1 tablespoon freshly grated ginger
2-4 teaspoons red pepper flakes OR 8-12 dried red chilies, deseeded and cut into halves
18 oz. can sliced water chestnuts, drained
2 stalks celery, chopped
1 red bell pepper, chopped
2 cups snow peas, ends trimmed and cut in half
5 stalks green onion, chopped
Salt and pepper to taste
1 cup peanuts

Prep and pantry notes

Before you get cooking, take a moment to prep everything: slice the chicken into uniform bite-size pieces so they cook evenly; mince the garlic and grate the ginger; chop the celery, bell pepper, and green onions; halve the snow peas; and drain the water chestnuts. Measure the cornstarch and sauce ingredients into a bowl so the sauce is ready to go. If you prefer less heat, start with 2 teaspoons of red pepper flakes or fewer chilies; add more after tasting if you want it spicier. Make sure your noodles are cooked just al dente — they’ll finish in the stir-fry and absorb the sauce.

Step-by-step instructions

The following directions are rewritten for clarity and flow while keeping your ingredient amounts and the original order intact. Read them through once, then follow along while you cook.

Cook the noodles: Bring a large pot of salted water to a boil. Add the 8 oz. vermicelli or thin spaghetti and cook until just al dente according to package instructions. Drain and toss the noodles with a drizzle of sesame oil to prevent sticking. Set aside.
Toss the chicken with cornstarch: Place the 2 large chicken breasts, cut into bite size pieces (1 pound), in a bowl. Sprinkle 2 tablespoons cornstarch over the chicken and toss until each piece is lightly coated. This creates a slight crust when stir-fried and helps thicken the sauce later.
Whisk the sauce: In a small bowl, combine 1/2 cup rice vinegar, 1/2 cup reduced sodium soy sauce, 1/4 cup sugar, and 1/4 teaspoon pepper. Stir until the sugar dissolves. Set this mixture nearby so it’s ready when you need it.
Preheat the pan: Heat a large wok or heavy skillet over medium-high heat until very hot. Add a couple teaspoons of neutral oil with a small splash of sesame oil for flavor.
Cook the chicken: Add the cornstarch-coated chicken pieces in a single layer without crowding; cook in batches if necessary. Sear the chicken for about 2–3 minutes per side until golden and almost cooked through. Remove the chicken to a plate and set aside.
Sauté aromatics and spice: Reduce heat to medium. Add another drizzle of oil if the pan looks dry. Add the 5 minced garlic cloves and 1 tablespoon freshly grated ginger and sauté for 30–45 seconds, stirring constantly, until fragrant but not browned. Stir in 2–4 teaspoons red pepper flakes OR the 8–12 dried red chilies (deseeded and halved) and toast briefly for extra fragrance.
Add the vegetables: Add the chopped 2 stalks celery, 1 red bell pepper (chopped), 2 cups snow peas (trimmed and halved), and the 18 oz. can sliced water chestnuts (drained). Stir-fry for 2–3 minutes until the vegetables are crisp-tender — you want them to keep some bite.
Return the chicken to the pan: Add the seared chicken back into the wok or skillet and toss to combine with the vegetables and aromatics.
Pour in the sauce: Give the sauce a quick stir, then pour the rice vinegar and soy mixture over the chicken and vegetables. Stir and let the sauce simmer for 1–2 minutes so it starts to reduce slightly and glaze the ingredients.
Combine noodles and adjust seasoning: Add the cooked noodles to the pan and toss them through the saucy mixture until evenly coated. If the noodles seem dry, splash in a teaspoon or two of water or more sesame oil. Taste and season with salt and pepper to taste.
Finish with green onion and peanuts: Stir in 5 chopped stalks of green onion and 1 cup peanuts. Toss briefly, just to warm the green onions and toast the peanuts slightly. Turn off the heat.
Rest and serve: Let the stir-fry sit for a minute to allow flavors to settle, then serve hot. Garnish with extra chopped green onions or a sprinkling of crushed peanuts if desired.

Troubleshooting and tips

Noodles clumping? Toss them with a little sesame oil right after draining and keep them warm in a covered bowl until ready to add to the pan.
Sauce too thin? Mix an extra 1/2 teaspoon cornstarch with a tablespoon of cold water, stir into the pan, and simmer for a minute until thickened.
Too spicy? Remove some of the red pepper flakes or chilies next time, or add a touch more sugar to balance heat with sweetness.
Chicken sticking? Make sure the pan is hot and don’t overcrowd it; searing the chicken in batches will prevent steaming and promote color.

Make-ahead and storage

You can prep the chicken, chop the vegetables, and whisk the sauce up to a day ahead; store everything in airtight containers in the fridge. Cook the noodles and assemble the stir-fry right before serving for the best texture. Leftovers refrigerate well for 2–3 days; reheat gently in a skillet with a splash of water or oil so the noodles don’t dry out.

Serving suggestions

This stir-fry is a complete meal on its own, but it pairs nicely with a simple cucumber salad for contrast or steamed greens for extra veggies. A squeeze of fresh lime brightens the plate at the end if you enjoy a citrus note.

Flavor variations

Sweeter glaze: Increase the sugar to 1/3 cup for a noticeably sweeter, more caramelized sauce.
Peanutty twist: Stir in a tablespoon of smooth peanut butter with the sauce for deeper nuttiness.
Veg-forward: Add sliced mushrooms, baby corn, or broccoli florets to bulk up the vegetable component.

Notes on ingredients

Reduced sodium soy sauce keeps the dish from becoming excessively salty while still delivering savory umami. Rice vinegar contributes bright acidity that balances the sugar and soy. The cornstarch has two roles: it gives the chicken a light, crisp coating and helps the sauce cling to the noodles. Use peanuts for crunch; if you have a peanut allergy, substitute toasted sunflower seeds or cashews instead.

Final thoughts

This OLD Kung Pao Chicken Noodle Stir Fry is an everyday favorite that hits all the right notes: bold, balanced, and texturally satisfying. It’s easy to scale up for guests, quick enough for weeknights, and flexible so you can swap or add vegetables based on what you have on hand. Follow the clear, step-by-step directions above for reliable results, and don’t be afraid to tweak the heat or sweetness to match your preferences. Happy cooking!
