Spicy Cashew Chicken — A Chinese-Style Stir Fry

This spicy cashew chicken recipe is a fast, high-heat wok stir fry — chicken, roasted cashews, and a glossy soy-based sauce with real chilli heat, ready in about 20 minutes total. No tandoor involved anywhere here; this is a Chinese-American stir fry built entirely on a hot wok or pan.

This guide covers why the chicken needs to be velveted before it hits the wok, how to keep the cashews crunchy rather than soggy, and the sauce timing that gets a properly glossy coating rather than a thin, watery one. If your stir fry cashew chicken has come out with soggy nuts or rubbery chicken before, this guide covers exactly why.

What You'll Need

Everything prepped and ready before the wok gets hot — stir frying moves fast.

For the Chicken and Velveting

• 1.5 lbs boneless chicken breast, cubed
• 1 egg white
• 1 tablespoon cornstarch
• 1 tablespoon Shaoxing wine or dry sherry

For the Stir Fry

• 1 cup roasted cashews
• 3 dried red chillies, or 1 teaspoon chilli flakes
• 3 cloves garlic, minced
• 1 tablespoon grated ginger
• 2 green onions, sliced
• 2 tablespoons oil, for stir frying

For the Sauce

• 3 tablespoons soy sauce
• 1 tablespoon oyster sauce
• 1 tablespoon rice vinegar
• 1 tablespoon sugar
• 2 tablespoons water
• 1 teaspoon cornstarch

A note on prep: have every ingredient measured, chopped, and within reach before you turn on the heat — a proper stir fry moves too fast to pause and prep mid-cook.

Adjusting the Heat Level

Heat level in this Chinese cashew chicken comes almost entirely from the dried chillies, making it easy to adjust without touching anything else.

Mild

Use just 1 dried chilli, or skip the chilli flakes substitute entirely, for a dish that leans more on the savoury sauce than heat.

Medium (Recommended, Used Above)

3 dried chillies gives noticeable warmth without overwhelming the dish — the default assumed by the recipe above.

Hot

Increase to 5 or 6 dried chillies, or add a small spoonful of chilli garlic sauce along with the stir fry sauce for real heat.

Step by Step

1

Velvet the Chicken

Combine the chicken with egg white, cornstarch, and Shaoxing wine. Let sit 15 minutes.

2

Make the Sauce

Whisk together all the sauce ingredients in a small bowl.

3

Stir Fry the Chicken

Heat the oil in a wok until very hot. Stir fry the chicken until just cooked through, then remove.

4

Bloom the Aromatics

In the same pan, stir fry the dried chillies, garlic, and ginger for 30 seconds, until fragrant.

5

Combine

Return the chicken to the pan along with the roasted cashews.

6

Add the Sauce

Pour in the sauce and toss until glossy and thickened, about 1 minute.

7

Finish and Serve

Finish with sliced green onions and serve immediately.

Why Velveting Keeps the Chicken Tender at Stir Fry Heat

Stir frying uses higher heat than almost any other home cooking technique, and chicken breast in particular can turn tough and rubbery under that heat without a specific preparation step first.

Why Egg White and Cornstarch Protect the Meat

Velveting coats the chicken's surface in a thin layer of egg white and cornstarch, which cooks into a protective barrier that shields the meat underneath from the wok's intense direct heat. Without that barrier, the outside of the chicken can overcook and toughen before the inside is even close to done.

Why Cashews Go In Late, Not Early

Cashews are already fully cooked from roasting, so adding them at the start would only expose them to unnecessary extended heat and moisture from the sauce, softening their crunch. Adding them just before the sauce keeps them crisp against the glossy, saucy chicken.

Confirming the Chicken Is Fully Cooked

USDA guidance requires 165°F for chicken — given how quickly stir frying cooks small pieces, a quick visual and texture check (opaque throughout, firm but not rubbery) combined with a thermometer spot check is a reliable way to confirm doneness.

What to Serve Cashew Chicken With

This spicy cashew chicken recipe is traditionally served over steamed white rice, which soaks up the glossy sauce well. A side of simple steamed or stir-fried greens rounds out the meal nicely.

For a completely different chicken and heat direction, our gochujang chicken recipe elsewhere on this site uses a Korean chilli paste glaze instead of a Chinese stir fry sauce.

Additional Technique Notes

Prep Everything Before Turning On the Heat

Stir frying moves fast — there's no time to chop or measure mid-cook.

Velvet the Chicken

Don't skip this step — it's what keeps the chicken tender at the high heat stir frying requires.

Keep the Wok Genuinely Hot

A properly hot wok sears rather than steams — if the pan isn't hot enough, the chicken will release liquid and stew instead.

Add Cashews Late

This keeps them crunchy rather than letting them soften in the sauce.

Confirm Doneness

Per USDA guidance, chicken should reach 165°F — check a larger piece with a thermometer if you're ever unsure.

Common Problems and Fixes

The Chicken Was Tough or Rubbery

Almost always a skipped or rushed velveting step. Give the chicken its full 15 minutes with the egg white and cornstarch coating.

The Cashews Were Soggy

Added too early. Stir them in only in the final couple of minutes, right before the sauce.

The Sauce Was Too Thin

Make sure the cornstarch in the sauce is fully whisked in with no clumps, and let it simmer briefly to thicken before removing from heat.

The Dish Tasted Steamed Instead of Seared

The pan likely wasn't hot enough, or too much chicken was added at once. Work in batches if needed and make sure the oil is shimmering before adding anything.

Storing Leftover Cashew Chicken

This dish keeps in an airtight container for up to 3 days refrigerated, though the cashews will soften somewhat in storage. Reheat in a hot pan rather than the microwave for the best texture.

This dish isn't well suited to freezing, since both the chicken's velveted texture and the cashews' crunch suffer after thawing.

Where Cashew Chicken Fits

This stir fry cashew chicken is a Chinese-American restaurant staple, drawing on genuine Chinese stir fry technique — velveting, high-heat wok cooking, a glossy cornstarch-thickened sauce — while representing a dish more associated with American Chinese restaurants than mainland Chinese home cooking.

A General Note on Nutrition

Cashews add healthy fats and a good amount of protein on top of the chicken's own contribution, making this a genuinely satisfying, protein-forward stir fry. As with any recipe, check ingredients against your own dietary needs via USDA FoodData Central rather than relying on general notes like this one.
