Crispy Korean Popcorn Chicken is bite-sized pieces of chicken coated in a cornstarch crust, air-fried (or baked) until crispy, then tossed in a sweet, spicy gochujang sauce. Ready in about 30 minutes, better than takeout and far more addictive.

If my husband and I have a weakness… it’s crispy chicken. And if it’s spicy too, we’re completely done for. This is one of those recipes I make almost every Friday after work, when that “let’s just order takeout” feeling kicks in. Except this version is genuinely better than anything that arrives in a box, and it’s on the table in about the same amount of time it takes for delivery to show up.

The chicken comes out properly crispy. Not just “crispy for five minutes” crispy, but actually holds up once it’s tossed in the sauce. And that sauce… sweet, garlicky, with just the right amount of heat from gochujang. It’s the kind of thing you’ll want to put on everything.

WHAT IS KOREAN POPCORN CHICKEN?

Korean popcorn chicken (sometimes called Korean fried chicken bites) is small pieces of chicken that are coated in a light, starchy batter, fried or air-fried until golden and crispy, then tossed in a sticky, flavourful sauce. It’s a popular Korean street food and bar snack, often served with pickled radish or a cooling cucumber salad to balance the heat.

This version keeps things simple. No deep frying required, just an air fryer (or oven) and a quick homemade sauce that comes together while the chicken cooks.

FOOD SCIENCE CORNER

Why “slightly clumpy is perfect”? The science of a crispy coating

The combination of cornstarch, flour and a small amount of baking powder isn’t random. Each ingredient is doing a specific job.

Cornstarch doesn’t contain gluten, so it doesn’t form the stretchy, chewy texture that wheat flour does. Instead, when it hits hot oil or hot air, it dehydrates quickly and forms a light, brittle, glass-like shell. This is the main reason cornstarch-coated fried foods are so much crispier than flour-only coatings.

Flour adds a small amount of structure and helps the coating adhere to the chicken. Too much cornstarch alone can flake off too easily.

Baking powder is the secret for that craggy, extra-crunchy texture. It releases tiny bubbles of carbon dioxide as it heats, creating little air pockets in the coating. These pockets increase the surface area, which means more crispy edges and less smooth, uniform crust.

This is also why the texture should look “slightly clumpy” before cooking. Those uneven clumps and ridges become the craggiest, crunchiest bits once cooked. A perfectly smooth coating actually fries up flatter and less crispy.

HOW TO MAKE IT

Please note: This is just an overview – the full ingredients and directions are in the recipe card at the bottom of this post.

Prepare the chicken: In a bowl, mix the chicken with egg, soy sauce, salt and pepper until evenly coated.

Coat the chicken: Add cornstarch, flour, and baking powder. Toss until well coated. Slightly clumpy is perfect (see why above!).

Cook the chicken: Spray chicken pieces with cooking oil on both sides, then air fry at 200°C / 400°F for 12 minutes until crispy. You can also use an oven – cook at 220°C / 425°F for 15–20 minutes, flipping halfway.

Make the sauce: In a pan over medium heat, combine all sauce ingredients except butter. Simmer for 3–4 minutes until slightly thickened, then turn off the heat and stir in the butter.

Toss: Add the crispy chicken to a bowl, pour over the sauce, and toss to coat.

Serve: Serve over rice and top with green onions and sesame seeds.

TIPS AND STORAGE

For extra crispiness, make sure the chicken pieces aren’t touching in the air fryer basket. Give them space to crisp up on all sides.

Adjust the spice by increasing or decreasing the gochujang to your taste. Start with less if you’re not sure, you can always add more.

Storage: Leftovers of this crispy Korean popcorn chicken keep in the fridge for up to 3 days. For best results, store the chicken and sauce separately and reheat the chicken in the air fryer for a few minutes before tossing in the sauce. This keeps it from going soggy.

Reheating from frozen: You can freeze the cooked, unsauced chicken for up to 2 months. Reheat from frozen in the air fryer at 200°C until hot and crispy, then toss in freshly made sauce.

FAQ

Can I make this in a deep fryer instead of an air fryer?

Yes. Fry the coated chicken pieces in oil heated to 180°C (350°F) for 4–5 minutes, until golden and crispy, then follow the same sauce and tossing steps.

Is gochujang very spicy?

Gochujang has a moderate heat with a lot of sweetness and umami behind it. It’s spicy but not overwhelming. You can easily adjust the amount to make this milder or spicier.

Can I use chicken thighs instead of breast?

Yes, thighs work really well and tend to stay juicier. Just make sure pieces are cut to a similar size for even cooking.

Can I make the sauce ahead of time?

Yes, the sauce keeps in the fridge for up to a week. Reheat gently before tossing with freshly cooked chicken.
