Ingredients You’ll Need

Chicken

• 1.5 pounds boneless, skinless chicken thighs, cut into 1-inch pieces
  • Thighs stay juicier than breasts, but you can use chicken breast if you prefer leaner meat.
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 tablespoon soy sauce (use low sodium if you watch salt)
• 1 tablespoon rice vinegar or white vinegar
• 1 large egg white
• 1/3 cup cornstarch
• 1/4 cup all-purpose flour
• 1/2 teaspoon baking powder (helps extra crispiness)

Chilli Sauce

• 2 tablespoons neutral oil (canola, vegetable, or avocado oil)

• 6 cloves garlic, finely minced

• 1 tablespoon ginger, finely minced or grated

• 3 to 4 green onions, sliced (white and green parts separated)

• 2 to 3 fresh green chillies, sliced (use jalapeño for mild, serrano or Thai for hotter)

• 1 small red bell pepper, thinly sliced

• 1 small green bell pepper, thinly sliced

• 2 tablespoons soy sauce

• 1 tablespoon rice vinegar

• 1 tablespoon tomato ketchup (gives body and a touch of sweetness)

• 1 to 1.5 tablespoons Asian chilli sauce (like Sriracha or a chilli garlic sauce; adjust to taste)

• 1 tablespoon brown sugar or honey

• 1/3 cup water or low-sodium chicken broth

• 1 tablespoon cornstarch mixed with 2 tablespoons water (slurry to thicken)

Garnishes

• Extra sliced green onions
• Toasted sesame seeds (optional but tasty)
• Extra sliced chillies for heat lovers

Oil & Equipment

• 2 to 3 cups neutral frying oil
  • Use vegetable, canola, peanut, or sunflower oil. Avoid olive oil because it smokes quickly.
• Heavy-bottomed pot or deep skillet for frying
• Wire rack or paper towel lined tray
• Large wok or wide skillet for tossing the sauce and chicken
• Tongs or slotted spoon
• Instant-read thermometer if you want to track oil temperature

Pantry Shortcuts & Substitutions

• Use pre-minced garlic and ginger from a jar if you feel tired; just drain any extra liquid.
• Swap rice vinegar with apple cider vinegar or plain white vinegar if needed.
• Use frozen bell pepper strips in place of fresh peppers; add them straight to the pan.
• Use gluten-free tamari and a gluten-free flour blend instead of regular soy sauce and flour to keep the Crispy Chilli Chicken Recipe gluten-free.

Tips & Tricks

• Cut chicken pieces to similar size so they cook evenly and stay juicy.
• Pat chicken dry with paper towels before marinating so the coating sticks better.
• Chill the coated chicken in the fridge for 10 to 15 minutes so the crust sets and fries crispier.
• Heat oil to about 350 to 365°F; too low gives soggy chicken, too hot burns the crust.
• Fry chicken in small batches so the oil temperature stays hot and the pieces stay crisp.
• Double fry the chicken for extra crunch: first fry until pale golden, rest, then fry again until deep golden.
• Keep the sauce slightly thick but still pourable so it clings to the chicken without turning it soggy.
• Toss chicken in the sauce right before serving and serve immediately for best crunch.
• Taste the sauce before adding chicken and adjust salt, sugar, or chilli to your preference.
• Use a splatter screen if your stove likes to decorate your backsplash with oil.

How to Make Crispy Chilli Chicken Recipe

Step 1: Marinate the Chicken

Add the chicken pieces to a large bowl. Sprinkle in salt, black pepper, soy sauce, and vinegar. Mix well so every piece gets coated.

Add the egg white and stir again until the chicken looks glossy. In a separate small bowl, whisk together cornstarch, flour, and baking powder. Sprinkle this dry mix over the chicken and toss until every piece looks evenly coated and slightly sticky.

Let the chicken rest at room temperature for 10 minutes while you heat the oil. If your kitchen runs hot, slide the bowl into the fridge. This short rest helps the coating hydrate and cling to the chicken.

Step 2: Fry the Chicken

Pour oil into your heavy pot or deep skillet so it reaches about 2 inches deep. Heat the oil over medium-high heat until it reaches about 350 to 365°F, or until a small pinch of coating bubbles briskly when you drop it in.

Add chicken pieces carefully, one at a time, without crowding the pan. Fry each batch for about 4 to 5 minutes, turning occasionally, until the coating turns light golden and the chicken cooks through. Transfer fried pieces to a wire rack or paper towel lined tray.

After you fry all the chicken once, raise the heat slightly. Fry the chicken a second time in smaller batches for 1 to 2 minutes until deep golden and very crisp. Move the double-fried chicken back to the rack and keep it nearby.

Step 3: Build the Chilli Sauce Base

Heat 2 tablespoons of oil in a large wok or wide skillet over medium-high heat. Add minced garlic and ginger and stir constantly for about 30 seconds until fragrant and lightly golden. Add the white parts of the green onions and sliced fresh chillies.

Stir for another 30 to 60 seconds so the aromatics soften and release flavor. Add sliced bell peppers and stir fry for 2 to 3 minutes until they turn slightly tender but still hold some crunch. You want them bright and not floppy.

Step 4: Mix the Sauce

In a small bowl, whisk together soy sauce, vinegar, ketchup, chilli sauce, brown sugar or honey, and water or broth. Taste this mixture and adjust sweetness or heat to your liking.

Pour this sauce mixture into the wok with the aromatics and peppers. Bring it to a gentle simmer over medium heat. Stir the cornstarch slurry, then drizzle it into the simmering sauce while you stir.

Cook for 1 to 2 minutes until the sauce thickens and looks glossy and smooth. If it turns too thick, splash in a tablespoon or two of water and stir. If it looks too thin, simmer another minute or add a little more slurry.

Step 5: Toss the Chicken

Add the double-fried chicken pieces to the wok. Toss quickly so the sauce coats every piece. Add the green parts of the green onions and toss again.

Turn off the heat once the chicken looks evenly coated and the sauce clings nicely. Sprinkle with toasted sesame seeds and extra sliced chillies if you like more heat. Serve the Crispy Chilli Chicken Recipe immediately while the coating stays crunchy.

What to Serve with Crispy Chilli Chicken Recipe

Serve this Crispy Chilli Chicken Recipe with steamed jasmine rice or basmati rice so the grains soak up the extra sauce. Fried rice with veggies also works perfectly and turns the meal into a full takeout-style spread.

You can add a simple cucumber salad with lime and salt to cool down the spice. Stir-fried broccoli, snap peas, or mixed vegetables round out the plate and add some color and crunch.

Storage Options

• Store leftover Crispy Chilli Chicken Recipe in an airtight container in the fridge for up to 3 days.
• Keep the chicken and any extra sauce separate if possible so the coating stays a bit firmer.
• Freeze cooled chicken pieces on a baking sheet, then move them to a freezer bag and store for up to 2 months.
• Reheat chicken in a 375°F oven or air fryer for 8 to 10 minutes until hot and crisp; warm any leftover sauce separately on the stove and toss right before serving.
