War Su Gai Recipe: Silk-Smooth Cashew Chicken With Velvet Sauce

This Cantonese classic combines tender chicken with rich cashews in a velvety sauce that feels luxurious yet approachable. The technique of velveting chicken creates that signature silk-smooth texture that sets this dish apart.

I first encountered this dish at a small San Francisco restaurant, and spent years perfecting the balance of flavors at home. The sauce achieves its characteristic thickness through a simple cornstarch slurry, while the cashews add buttery richness.

What emerges is a dish with tender chicken pieces coated in a glossy, clingy sauce, studded with toasted cashews. The flavors are subtle yet deeply satisfying—a perfect example of Cantonese comfort food.

Serve with steamed rice to soak up every drop of that velvety sauce. This is authentic flavor made simple.

Ingredients for War Su Gai

Velveting creates that signature silk-smooth texture with simple pantry staples and a few key ingredients.

The chicken quality is paramount—boneless, skinless thighs work even better than breasts for extra tenderness. Source your cashews from Asian markets for the freshest, meatiest nuts. For cornstarch, Clabber Girl or any major brand works fine. The Shaoxing wine is non-negotiable for authenticity (find it at H Mart or online), but dry sherry in a pinch works.

No Shaoxing wine? Dry sherry at a 1:1 ratio. Out of oyster sauce? Vegetarian oyster sauce or a mix of soy sauce with a dash of sugar gets you close. Thickening the sauce without cornstarch? Arrowroot powder works at one-third the amount. For a gluten-free version, swap soy sauce for tamari and ensure oyster sauce is wheat-free.

Store raw cashews in an airtight container at room temperature for up to 1 month. The velveted chicken mixture can be prepped 4 hours ahead and refrigerated. Leftovers keep well for 3-4 days, though the sauce may thicken—thin with a splash of broth when reheating.

Step-by-Step Instructions for Cashew Chicken With Velvet Sauce

Master the velveting technique and achieve restaurant-quality texture with this proven method.

Step 1: Velvet the Chicken

Cut the 1.5 lb boneless chicken breast into bite-sized pieces and place in a bowl. Add the 2 whole egg whites, 1 tbsp cornstarch, 1 tbsp soy sauce, and 1 tbsp shaoxing wine. Mix gently until the chicken is uniformly coated in a thin, milky mixture.

This velveting process tenderizes the chicken and creates a silky texture. Let it marinate for 15 minutes at room temperature. The mixture should look slightly glossy and the chicken pieces should feel slippery—this indicates the cornstarch is working properly.

Step 2: Prepare the Sauce and Toast the Cashews

In a small bowl, combine the remaining 2 tbsp cornstarch with 2 tbsp soy sauce, 2 tbsp oyster sauce, 1 tbsp shaoxing wine, 1 tsp white sugar, 0.75 cup chicken broth, and 1 tsp sesame oil. Whisk until smooth and set aside.

Lightly toast the 1 cup raw cashews in a dry skillet over medium heat for 2-3 minutes until fragrant and lightly golden. Remove immediately to prevent burning—they’ll continue cooking from residual heat. Set aside for later use.

Step 3: Velvet-Fry the Chicken

Heat 1 cup vegetable oil in a wok or large skillet over high heat until shimmering but not smoking (350-375°F). Working in batches to avoid crowding, carefully add the marinated chicken pieces. They should sizzle immediately upon contact.

Cook for 1-2 minutes until the chicken turns opaque and the exterior sets into a delicate crust. The pieces will float when done. Remove with a slotted spoon and drain on a wire rack or paper towels. The chicken should be just cooked through—it will finish in the sauce.

Step 4: Stir-Fry Aromatics and Combine

Carefully pour off all but 2 tbsp vegetable oil from the wok. Over high heat, add the 3 cloves garlic cloves and 1 tbsp fresh ginger. Stir-fry for 30 seconds until fragrant but not browned—garlic burns quickly, so keep it moving.

Give the sauce mixture a quick stir (it may have settled) and pour it into the wok. Bring to a boil, then add the velvet-fried chicken and toasted cashews. Toss gently to coat everything in the glossy sauce. Cook for 1-2 minutes until the sauce thickens to a velvety consistency that clings to the chicken.

Step 5: Finish and Garnish

Taste and adjust seasoning with 0.5 tsp kosher salt if needed. Sprinkle with thinly sliced 3 whole green onions and give a final toss. The sauce should be thick enough to coat the back of a spoon but still flowing.

Transfer to a serving platter immediately. The chicken should be tender with a silky, almost custard-like interior, while the cashews add crunch. Serve over steamed rice to soak up every bit of that luxurious velvet sauce.

Make-Ahead Tips for This Recipe

Prep Ahead Velveting

You can velvet the chicken up to 4 hours ahead and refrigerate it. The cornstarch and egg white mixture actually improves with a little rest time, creating an even silkier texture when cooked. Just give it a quick stir before frying. 💡

Cashew Toasting

Toast your 1 cup raw cashews the night before and store them at room temperature in an airtight container. They’ll stay fresh for 2-3 days, saving you precious minutes when you’re ready to cook.

This also lets the flavors deepen slightly, adding more complexity to your final dish.

Sauce Pre-Mixing

Combine all your sauce ingredients except the cornstarch slurry the day before. The flavors meld beautifully overnight. Just whisk in the 2 tbsp cornstarch right before cooking to prevent settling.

Partial Cook Method

Velvet-fry the chicken completely, then cool and refrigerate for up to 24 hours. When ready to serve, simply reheat the chicken in the freshly made sauce for 2-3 minutes until hot. 🔥

Freezing Tips

This dish freezes surprisingly well for up to 1 month. Portion into airtight containers before freezing. Thaw overnight in the refrigerator, then reheat gently with a splash of chicken broth to restore the sauce’s velvety texture.

Reheating Trick

For leftovers, add 1-2 tbsp water or broth when reheating to loosen the sauce. Cover and warm over medium-low heat for 5-7 minutes, stirring occasionally. The cashews may soften slightly but will still add great texture.
