Korean Fried Chicken Recipe: Get the Crispy Secret | Step-by-Step

There’s a reason Korean fried chicken has become a global obsession. That shatteringly crisp shell comes from a deceptively simple technique: double frying. Korean cookbook author Maangchi (Korean cookbook author) explains that the first fry at a moderate temperature cooks the chicken through, and the second fry at higher heat creates that ultra-crispy crust. This guide walks you through the exact steps and sauce secrets so you can replicate restaurant-quality chicken at home.

Crispy secret: Double frying ·
Key sauce ingredient: Gochujang ·
Typical preparation time: 1–2 hours ·
Popular accompaniment: Pickled radish

Five key facts, one takeaway: the starch coating and double fry are non-negotiable, while the sauce allows room for personal taste.

Here’s how the foundational elements break down.

What is the secret to Korean fried chicken?

What makes Korean fried chicken so good?

The secret lives in the double fry. Drive Me Hungry (Korean recipe blog) explains that the first fry renders fat from the skin while the second fry produces a crisp, crunchy crust that stays crunchy even after saucing. The coating is a thin batter made from cornstarch or potato starch — not a thick flour breading. Hungry Huy (Vietnamese food blog) notes that the sweet, gochujang-spiked glaze is what sets it apart from American fried chicken.

The implication: the double-fry isn’t optional—it’s the defining technique that separates Korean fried chicken from all others.

What ingredients do I need?

You’ll need chicken wings or drumettes, cornstarch or potato starch, salt, pepper, and oil for frying. For the sauce, gather gochujang, honey or rice syrup, soy sauce, garlic, ginger, and rice vinegar. Kitchen Sanctuary (UK food blog) uses gochujang paste, honey, brown sugar, soy sauce, garlic, and ginger. Rebecca Lang Cooks (Southern cookbook author) adds sesame oil and rice vinegar for depth.

Step-by-step instructions

1. Marinate chicken in rice wine or milk for 30 minutes.
2. Dredge in starch, salt, and pepper mixture.
3. First fry at 165°C (330°F) for 7–8 minutes (Aaron and Claire YouTube).
4. Rest chicken on wire rack for 5–10 minutes.
5. Second fry at 180°C (355°F) for 12–15 minutes until deep golden.
6. Toss in sauce: simmer gochujang, honey, soy sauce, garlic, and ginger until sticky.

The pattern: each step in the process is designed to remove moisture, which is the enemy of crispiness.

What is the coating on Korean fried chicken?

What is the batter for Korean fried chicken?

The coating is a thin starch slurry, not a wet flour batter. Maangchi (Korean cookbook author) seasons the chicken, coats it in cornstarch, then fries. The starch forms a thin, lace-like crust that stays delicate. Potato starch creates a more brittle crust, while cornstarch yields a slightly lighter crunch. Rebecca Lang Cooks confirms that no flour-based breading is used — the starch is the secret.

The implication: the choice between potato and cornstarch comes down to which texture you prefer—brittle versus light.

How do Koreans achieve extra crunch?

Double frying is the core technique, but the starch choice also matters. Joshua Weissman (chef and YouTuber) emphasizes that the second fry must be hot enough to create a dry crust. Woo Can Cook (cooking channel) recommends using potato starch for a more crackly exterior. Allowing the chicken to rest between fries lets the surface dry out, so the second fry doesn’t steam the coating.

What this means: the resting period between fries is as critical as the frying itself—skipping it means losing the signature crunch.

How to make Korean fried chicken sauce?

What is the best gochujang sauce recipe?

The classic yangnyeom sauce starts with gochujang. Maangchi’s version includes ketchup, rice syrup, gochujang, soy sauce, vinegar, garlic, and sugar. Crab Cakes and Kimchi (Korean fusion blog) builds with garlic, ketchup, sriracha, gochujang, mirin, and brown sugar. Combine ingredients in a saucepan, simmer until thick, then toss with fried chicken. Adjust spiciness by adding or reducing gochujang.

How to adjust spiciness

• Mild: use 1 tablespoon gochujang, increase honey or ketchup.
• Medium: 2 tablespoons gochujang, a pinch of red pepper flakes.
• Hot: add gochujang, sriracha, or fresh chili.

Woo Can Cook includes honey and sweet chili sauce to balance heat. Weissman adds mirin for acidity. Rice vinegar appears across multiple recipes as the acid that cuts richness.

The catch: without the acid component, the sauce becomes cloying—the vinegar is what makes the glaze work.
