Ingredients You’ll Need

You can use boneless, skinless chicken thighs or breasts. I prefer thighs because they stay juicier and more forgiving if you cook them a minute too long.

Chicken and Marinade

• 1.5 pounds boneless skinless chicken thighs, cut into 1 inch pieces
  • Use chicken breast if you prefer leaner meat, but watch the cooking time.
• 1 tablespoon soy sauce
  • Use low sodium soy sauce if you watch salt.
• 1 tablespoon rice vinegar or apple cider vinegar
• 1 teaspoon toasted sesame oil
• 1 teaspoon grated ginger
• 2 cloves garlic, minced
• 1 teaspoon chilli flakes or Korean gochugaru
  • Gochugaru gives a deeper color and milder heat.
• 1 large egg white, lightly beaten
• ½ teaspoon salt
• ¼ teaspoon black pepper

Crispy Coating

• ½ cup cornstarch
• ¼ cup all purpose flour
• ½ teaspoon baking powder
• ½ teaspoon salt
• ¼ teaspoon black pepper

Cornstarch gives that light, crackly crust. If you avoid gluten, swap the flour with more cornstarch and skip the baking powder.

Chilli Sauce

• 2 tablespoons neutral oil (canola, vegetable, or avocado)
• 4 cloves garlic, minced
• 1 tablespoon grated ginger
• 2 to 3 fresh red chillies, finely sliced
  • Use jalapeño for milder heat or Thai chillies for serious spice.
• 1 small onion, thinly sliced
• 1 small red bell pepper, thinly sliced
• 1 small green bell pepper, thinly sliced
• 3 tablespoons soy sauce
• 2 tablespoons ketchup
  • I like Heinz for consistent sweetness and thickness.
• 1 tablespoon chilli sauce (like Sriracha or a generic Asian chilli sauce)
• 1 tablespoon rice vinegar
• 1 to 2 tablespoons brown sugar, to taste
• ½ cup water or low sodium chicken broth
• 1 tablespoon cornstarch mixed with 2 tablespoons water (slurry)

Garnishes

• 2 to 3 green onions, thinly sliced
• 1 tablespoon toasted sesame seeds
• Extra chilli flakes, to taste

Oil and Equipment

• 2 to 3 cups neutral frying oil
  • Use canola, vegetable, or peanut oil. Avoid olive oil because it smokes too quickly.
• Large heavy skillet or wok
• Medium mixing bowls
• Tongs or chopsticks
• Wire rack or paper towel lined plate
• Whisk and spatula

Tips & Tricks

• Pat the chicken dry before marinating so the coating sticks better.
• Cut the chicken into similar sized pieces so everything cooks evenly.
• Marinate at least 15 minutes; if you have time, chill it for 30 minutes for deeper flavor.
• Coat the chicken right before frying so the crust stays light and crisp.
• Toss the chicken in the dry coating and press it in gently with your fingers for a thicker crust.
• Heat the oil until a small pinch of coating sizzles instantly; aim for about 350 to 360°F.
• Fry in small batches so the oil temperature stays hot and the chicken turns crisp, not soggy.
• Use a wire rack instead of paper towels if you want extra crunch.
• Stir the sauce slurry again right before you pour it in because cornstarch settles.
• Add the fried chicken to the sauce at the very end and toss quickly so the crust stays crisp.
• Taste the sauce before adding the chicken and adjust salt, sugar, or chilli to your liking.
• Serve right away because the crust tastes best within the first 20 minutes.

How to Make Crispy Chilli Chicken Recipe

Step 1: Prep and Marinate the Chicken

Place the chicken pieces in a bowl and add soy sauce, vinegar, sesame oil, ginger, garlic, chilli flakes, egg white, salt, and pepper. Mix everything well so each piece gets coated with the marinade. Cover and let it sit while you prep the other ingredients, at least 15 minutes.

Step 2: Mix the Crispy Coating

In a separate bowl, whisk together cornstarch, flour, baking powder, salt, and pepper. Take a piece of marinated chicken and drop it into the dry mix. Toss and press the coating onto the chicken until it looks evenly covered, then set it on a plate.

Repeat with all the chicken pieces. If any pieces look patchy, dip them lightly back into the marinade and then into the coating again. You want a thin, even layer that clings well.

Step 3: Fry the Chicken

Pour oil into a large skillet or wok, enough to reach about halfway up the chicken pieces. Heat the oil over medium high heat until it shimmers and a pinch of coating sizzles right away. Lower a few chicken pieces into the oil gently so you avoid splashes.

Fry in batches and avoid crowding the pan. Cook each batch for about 4 to 6 minutes, turning occasionally, until the chicken turns deep golden and feels firm. Transfer the fried chicken to a wire rack or paper towel lined plate and let it rest while you finish the rest.

If you want extra crunch, fry the chicken a second time for 1 to 2 minutes per batch. Double frying drives off extra moisture and keeps the crust crisp under the sauce.

Step 4: Build the Chilli Sauce

Pour off most of the frying oil and leave about 2 tablespoons in the pan. Set the heat to medium and add garlic and ginger. Stir and cook for 30 to 60 seconds until they smell fragrant and lightly golden.

Add sliced fresh chillies, onion, and bell peppers. Stir fry for 2 to 3 minutes until the veggies soften slightly but still keep some crunch. In a small bowl, whisk together soy sauce, ketchup, chilli sauce, vinegar, brown sugar, and water or broth.

Pour this sauce mixture into the pan and stir. Bring it to a gentle simmer. Taste and adjust sweetness or heat at this point.

Step 5: Thicken the Sauce

Stir the cornstarch slurry again so it looks smooth. Slowly pour it into the simmering sauce while you stir constantly. The sauce will thicken and turn glossy within 1 to 2 minutes.

If the sauce looks too thick, splash in a bit more water. If it looks too thin, cook it another minute or add a tiny bit more slurry. You want a sauce that coats the back of a spoon and clings to the chicken.

Step 6: Toss the Chicken

Add the fried chicken pieces to the pan with the sauce. Toss quickly and gently so every piece gets a shiny coat without breaking the crust. Turn off the heat once everything looks evenly coated.

Sprinkle in green onions and sesame seeds. Toss one more time and taste a piece. Adjust with extra chilli flakes or a tiny pinch of salt if you want a stronger kick.

Step 7: Garnish and Serve

Transfer the Crispy Chilli Chicken Recipe to a serving platter or shallow bowl. Top with extra green onions, sesame seeds, and sliced fresh chilli if you like more heat. Serve it hot while the crust still feels crisp.

What to Serve with Crispy Chilli Chicken Recipe

This Crispy Chilli Chicken Recipe pairs beautifully with steamed jasmine rice, fried rice, or simple garlic noodles. You can add a side of stir fried vegetables like broccoli, snap peas, or bok choy to balance the richness. A crisp cucumber salad with lime and a pinch of salt cools the spice and adds freshness. If you want a fun spread, serve it with veggie spring rolls, plain rice, and a simple egg drop style soup.

Storage Options

• Store leftover Crispy Chilli Chicken Recipe in an airtight container in the fridge for up to 3 days.
• Chill the chicken completely before you close the container so condensation does not soften the crust too much.
• Freeze portions in freezer safe containers or bags for up to 2 months; label with the date so you keep track.
• Reheat in an air fryer at 350°F for 5 to 8 minutes or in a hot oven at 400°F for about 10 minutes until hot and crisp again.
• If the sauce thickens too much after chilling, stir in a spoonful of water while you reheat on the stovetop.
