I don’t deep fry that often, but this sweet crispy Korean fried chicken is the one I’ll break out the oil for every single time. You’re getting audibly crunchy chicken tossed in a sweet, tangy, slightly spicy glaze with garlic, ginger and dried red peppers. This style’s called dakgangjeong, and the entire secret is the double fry. You fry once to cook the chicken through, let it rest, then fry it again for that signature crunch. Toss it in the sauce at the very last second, hit it with sesame seeds, and that’s it!

What Makes This Sweet Crispy Korean Fried Chicken So Good

It’s the contrast, and for me that’s what separates good Korean fried chicken from great. That craggy potato starch crust stays crisp even after it’s coated in a sticky sauce (which is basically the holy grail here, and the reason people obsess over this stuff). The sauce is sweet and tangy with a little heat from the dried red peppers, and there’s a hit of yellow mustard in there that keeps it from going one-note. Make it once and you’ll get why I say it’s worth the effort!

Plus, this is one of the few recipes where I’ll happily do the fussy version. I’m usually all about the shortcut, but the double fry earns its keep. If you’re into those sweet-savory Korean flavors, my air fryer Korean short ribs hit a similar note with LA-style galbi that’s done in under ten minutes, and that one IS the shortcut version.

On the faster end of that same sweet-savory Korean spectrum, the Bulgogi Pajeon Sandwich puts saucy bulgogi beef and melted cheese inside a crispy scallion pancake and comes together in well under 30 minutes.

How Do Koreans Make Their Chicken So Crispy?

Potato starch and a double fry, and I’d argue you really do need both. Potato starch fries up lighter and crunchier than regular flour, and frying twice drives out the extra moisture so the crust goes crazy crisp instead of soft. The first fry at 350F cooks the chicken through, and the second one takes it deeply golden and properly crisp and brittle. If you’d rather skip deep frying altogether, my crispy baked chicken wings get crisp in the oven with a baking powder trick instead, but for that real dakgangjeong crunch you want the fry.

Tips for Making Sweet Crispy Korean Fried Chicken

1. Soak the chicken in milk

Thirty minutes in milk tenderizes the chicken and mellows out any gamey edge before you season it. But drain it really well, and I mean really, because wet chicken plus potato starch gives you paste instead of a coating!

2. Use potato starch, not flour

This is what gives you that light, crispy crust, and flour won’t get you there. Throw the starch in a ziploc with the chicken, seal it, and shake until every piece is covered, then park it in the fridge until you’re ready to fry. I use Assi, same as the minced garlic and ginger in the sauce.

3. Respect the double fry

Fry once at 350F for 1 to 2 minutes just to cook it through, then rest the pieces on a wire strainer. Bring the oil back to 340 to 350F and fry the whole batch again for 3 to 4 minutes until it’s deeply golden. That second fry is the entire reason this stays crunchy under sauce. I know it feels like one step too many, but don’t talk yourself out of it!

4. Sauce it at the very end

Cook the sauce until it’s bubbling and slightly sticky, then toss the chicken in right before you serve. Sauce it early and the crust goes soft on you, which undoes everything you just did. Finish with sesame seeds and give it 5 to 10 minutes so the glaze sets up.

Storage and Leftovers

This is best the moment it’s sauced, when the crust is at its peak. Leftovers keep in the fridge for up to 3 days, and a quick pass in the air fryer or a hot oven brings the crunch right back! I’d skip the microwave completely, since it just steams everything soft.

Serve it as an appetizer, a party platter, or a full meal over rice. For a cozy noodle side, my gochujang butter udon gives you chewy udon in a sweet-spicy gochujang butter sauce that plays right off this chicken.

Equipment

• Wok
• Kitchen thermometer
• Large strainer
• Mixing bowls

Ingredients

For the chicken:

• 1 lb boneless skinless chicken, chopped
• 1/2 cup milk
• 1/2 teaspoon salt
• 1/4 teaspoon ground black pepper
• 1 cup Assi potato starch
• 6 small dried red peppers
• Cooking oil, for frying

For the sauce:

• 2 teaspoons Assi minced garlic
• 2 teaspoons Assi minced ginger
• 1 tablespoon Assi soy sauce
• 1/2 cup rice syrup
• 1 tablespoon sugar
• 2 teaspoons apple cider vinegar
• 1 tablespoon yellow mustard
• 1 tablespoon Assi roasted sesame seeds
• 1 tablespoon vegetable oil

Substitutions and Swaps

• Potato starch. Cornstarch is the closest thing you’ve got, and it’ll still be crispy, it just won’t go as craggy or as light. Regular flour is the one I’d rule out completely, because it gives you a heavier crust that softens the second the sauce touches it.
• Rice syrup. This is what makes the glaze glossy and sticky without being cloying. Corn syrup is the closest swap, and honey works but it’s sweeter and scorches faster, so keep the heat lower if you go that way.
• The chicken. Boneless thighs are what I’d point you toward, since they stay juicy through two fries. Breast works fine, just cut the pieces a bit bigger and keep an eye on that second fry, because it dries out much faster.
• The dried red peppers. Gochugaru gives you the heat without the whole peppers floating around, and you can leave them out entirely for a kid-friendly version. The sauce is still great, it’s just purely sweet and tangy.
• The yellow mustard. It sounds like the odd one out and it’s actually doing a lot of work, cutting the sweetness so the glaze isn’t flat. I wouldn’t skip it. Dijon works but brings a sharper, more grown-up flavor.

Instructions

1. Soak the chopped chicken in milk for 30 minutes, then drain it well and season with the salt and black pepper.
2. Add the potato starch to a large ziploc bag, drop in the chicken, seal it and shake until evenly coated. Keep it in the fridge until you’re ready to fry.
3. In a bowl, mix the rice syrup, soy sauce, sugar, apple cider vinegar and yellow mustard. Set it aside.
4. Heat 1 tablespoon of oil in a large pan or wok over medium-high. Add the garlic and ginger and cook about 1 minute, until the garlic turns light brown.
5. Toss in the dried red peppers and stir for 30 seconds, then pour in the sauce mixture. Stir gently for a few minutes until it’s bubbling and slightly sticky, then take it off the heat.
6. Heat 2 to 3 inches of oil in a large pan to 350F. Add the chicken pieces one at a time, working in batches, and fry for 1 to 2 minutes. Transfer to a wire strainer.
7. Bring the oil back to 340 to 350F and fry the whole batch a second time for 3 to 4 minutes, until very crunchy and golden brown. Back onto the strainer.
8. Reheat the sauce until it’s bubbling. Transfer the chicken to a bowl and toss it in the sauce.
9. Sprinkle with roasted sesame seeds and let it cool 5 to 10 minutes. If any pieces stick together, gently pull them apart with your hands.

The thing that makes this worth breaking out the oil is that the crunch survives the sauce. That’s the whole trick with dakgangjeong, and once you’ve had it hold up like that, regular fried chicken starts to feel like it’s missing a step.

It’s a weekend cook rather than a weeknight one, but it feeds a table and it’s worth planning an afternoon around. 🙌

If you make this, leave a star rating on the recipe card and tell me in the comments how the double fry went. It really helps other people find the recipe, and I want to hear if you took the heat up or down!
