Spicy Cashew Chicken

Please share this post with your friends 🤗

This Spicy Cashew Chicken is the kind of weeknight dish I reach for when I want something fast, bold, and reliably satisfying. It balances crunchy roasted cashews and bright scallions with a savory-spicy sauce that clings to each bite of tender chicken. The flavor is straightforward—no complicated pastes or long marinating—so it’s perfect when you want restaurant-style results without fuss.

In this version I keep the ingredient list tight and the technique simple: a hot wok, high heat, and quick stir-frying. That approach preserves the chicken’s juiciness while toasting the cashews and releasing the aromatics from garlic, onion, and dried chilies. Serve it over steamed rice and you have a complete meal in under 30 minutes.

I’ll walk you through a clear, step-by-step method, explain why each component matters, and offer swaps for allergies or when certain produce is in season. There are also practical storage tips and common mistakes to avoid so your Spicy Cashew Chicken comes out great every time.

Ingredient List

• 2 tablespoons oil — high-heat oil for stir-frying; heats quickly and prevents sticking.
• 2 cloves garlic, minced — provides a savory, aromatic base; mince finely so it browns quickly and evenly.
• 1/2 small onion, cut into halves — sliced halves add sweetness and texture; cut so pieces are easy to pick up with chopsticks or fork.
• 6-8 dried red chilies, finger-length, seeded and cut into halves — bring concentrated heat and a smoky note; remove seeds to moderate spice.
• 1/2 cup roasted cashew nuts, rinsed and drained — crunchy element and nutty flavor; rinsing removes excess surface salt if needed.
• 8 oz (230 g) chicken, cut into small cubes — bite-sized pieces cook quickly and get good sauce coverage.
• 1 scallion, trimmed and cut into 1 1/2-in (4 cm) lengths — stirred in at the end for freshness and a light oniony finish.
• 1 teaspoon soy sauce, or Maggi seasoning sauce / Golden Mountain sauce — umami backbone; use whichever you prefer for depth.
• 1 tablespoon sweet soy sauce — adds sweetness and a glossy coating; thicker and darker than regular soy.
• 1 teaspoon fish sauce — salty, savory punch; a little goes a long way toward complexity.
• 1/4 teaspoon sugar, or to taste — balances salty and spicy flavors; adjust to your preference.
• 2 tablespoons water — loosens the sauce slightly so it coats the chicken without becoming soupy.

How to Prepare Spicy Cashew Chicken

1. Prepare everything before you heat the wok: mince the garlic, halve the small onion, seed and halve the dried red chilies, rinse and drain the roasted cashew nuts, cut the chicken into small cubes, and trim and cut the scallion into 1½-inch (4 cm) lengths. Combine the soy sauce, sweet soy sauce, fish sauce, sugar, and water in a small bowl so the sauce is ready.
2. Heat a wok or large frying pan over medium-high to high heat until very hot. Add 2 tablespoons oil and swirl to coat the surface; the oil should shimmer but not smoke heavily.
3. Add the minced garlic, the halved onion, and the dried red chilies to the hot oil. Stir-fry quickly, tossing constantly, until the garlic is fragrant and the chilies release their aroma—about 30–60 seconds. Watch closely so the garlic does not burn.
4. Add the 1/2 cup roasted cashew nuts to the wok and toss for about 30–45 seconds to warm them and pick up flavor from the aromatics. The cashews may deepen in color slightly; stir so they do not scorch.
5. Add the 8 oz (230 g) cubed chicken to the wok. Spread the pieces in a single layer if possible and stir-fry, turning frequently, until the surfaces of the chicken turn opaque—about 3–5 minutes depending on the size of the cubes.
6. Pour the prepared sauce (1 teaspoon soy sauce, 1 tablespoon sweet soy sauce, 1 teaspoon fish sauce, 1/4 teaspoon sugar, and 2 tablespoons water) into the wok. Stir immediately to coat all the chicken pieces and cashews. Continue stir-frying briskly until the chicken is cooked through and the sauce thickens slightly and clings to the ingredients—another 2–3 minutes. Taste and adjust sugar or soy sauce if desired.
7. Stir in the 1 scallion cut into lengths and toss for about 10–15 seconds just to warm and soften it slightly; you want the scallion to remain bright and fresh.
8. Turn off the heat and transfer the Spicy Cashew Chicken to a serving dish. Serve immediately with steamed rice so the sauce and textures are at their best.

What You’ll Love About This Recipe

• Speed: It cooks very quickly—ready in about 20–30 minutes from start to finish.
• Texture contrast: Crunchy roasted cashews versus tender chicken makes every bite interesting.
• Flavor balance: Sweet soy and sugar tame the heat from dried chilies while fish sauce and soy provide deep umami.
• Minimal prep, maximum impact: Few ingredients but a complex, layered result.

Allergy-Friendly Substitutes

• Nut allergy: Omit cashews and increase the onion or add water chestnuts for crunch; toasted pumpkin seeds can work if tree nuts are okay.
• Soy allergy: Replace soy sauces with a blend of coconut aminos (use same quantity) and adjust salt to taste; omit sweet soy or use a little honey or maple for sweetness.
• Fish allergy: Skip fish sauce and add a pinch more soy sauce and a tiny dash of lime for depth.
• Nightshade sensitivity: Omit dried red chilies and add 1/4–1/2 teaspoon black pepper for warmth.

Cook’s Kit

• Wok or large heavy skillet — for high-heat stir-frying and quick tossing.
• Sharp chef’s knife — for quick, even cutting of chicken and aromatics.
• Small bowl — to mix the sauce in advance.
• Spatula or wok turner — to keep everything moving without breaking the chicken pieces.
• Steamed rice maker or saucepan — for serving alongside the dish.

What Not to Do

• Do not crowd the wok — overcrowding lowers the pan temperature and causes the chicken to steam instead of sear. Work in batches if necessary.
• Do not add the scallions too early — they should be added at the end to keep them bright and slightly crisp.
• Do not burn the garlic — keep it moving and remove from direct contact with the hottest spot if it begins to brown too quickly.
• Do not pour too much liquid at once — stick to the 2 tablespoons water specified so the sauce remains glossy and not watery.

In-Season Swaps

• Summer: Add julienned bell pepper or snap peas for fresh crunch and bright color.
• Autumn: Swap scallion for thinly sliced leeks when leeks are sweet and in season.
• Winter: Use a handful of roasted chestnuts (if you like) instead of cashews for a firmer, seasonal bite.
• Spring: Toss in blanched asparagus tips at the final stir for a light, fresh note.

Chef’s Rationale

I keep the technique simple and the heat high because that’s how you get the best texture and flavor quickly. Toasting the cashews in the wok with the aromatics lets them pick up the garlicky, chili-infused oil so every nut is flavored. Cutting the chicken into small cubes ensures rapid, even cooking and good sauce coverage. The combination of soy, sweet soy, and fish sauce provides saltiness, caramel sweetness, and savory depth; sugar smooths any sharp edges and the 2 tablespoons of water creates just enough looseness so the sauce coats instead of puddling.

Best Ways to Store

• Refrigerate: Cool to room temperature, then store in an airtight container for up to 3 days. Reheat gently in a skillet over medium heat with a splash of water to loosen the sauce.
• Freeze: You can freeze for up to 1 month. Thaw overnight in the refrigerator and reheat in a skillet; note the cashews will soften after freezing.
• Do not leave at room temperature for more than 2 hours to avoid bacterial growth.

Helpful Q&A

• Can I use raw cashews? You can, but they will brown faster in the wok. Reduce the time you stir them with the aromatics so they don’t burn.
• How spicy is this? The heat depends on the dried chilies you use. Removing seeds lowers the intensity. Start with 6 chilies and adjust next time based on your tolerance.
• Can I use dark meat like thigh? Yes—thigh meat is more forgiving and stays juicier. Keep the same cube size and cooking time, but check doneness a little earlier.
• Is this gluten-free? Not with regular soy sauce. Use tamari or coconut aminos to make it gluten-free.

Serve & Enjoy

Serve Spicy Cashew Chicken immediately over steamed jasmine or short-grain rice to soak up the savory-sweet sauce. Garnish with extra scallion slices or a wedge of lime for brightness if you like. Plate it family-style for casual dinners or portion it over rice bowls for quick lunches. Leftovers reheat well and make a great packed lunch.
