Why This Recipe Works

Double-frying removes extra moisture, creating a thin, super crisp shell that stays crunchy even after saucing.
Potato starch beats flour for crispness. It fries lighter and crunchier with less greasiness.
A quick marinade seasons the meat and tenderizes it without long wait times.
A balanced sauce—sweet, salty, garlicky, a little spicy—coats evenly and doesn’t sog out the crust.
Right oil temperatures ensure the chicken cooks through without burning the coating.

Ingredients

Chicken and Marinade

2 pounds chicken wings or boneless thighs, cut into 2-inch pieces
1 teaspoon kosher salt
1/2 teaspoon black pepper
1 tablespoon soy sauce
1 tablespoon rice vinegar (or apple cider vinegar)
2 cloves garlic, minced
1 teaspoon grated ginger
1 large egg white (optional, for extra adhesion)

Coating

1 cup potato starch (or cornstarch, but potato starch is best)
1/2 teaspoon baking powder
1/2 teaspoon garlic powder

Frying

Neutral oil for frying (canola, peanut, or vegetable), about 1.5–2 quarts

Sweet and Spicy Gochujang Sauce

2 tablespoons gochujang (Korean red chili paste)
2 tablespoons ketchup
3 tablespoons honey (or brown sugar)
2 tablespoons soy sauce
2 tablespoons rice vinegar
2 cloves garlic, minced
1 teaspoon grated ginger
1 tablespoon sesame oil
1–2 tablespoons water, as needed to thin
Sesame seeds and sliced green onions, for garnish

Step-by-Step Instructions

Season the chicken. In a bowl, toss chicken with salt, pepper, soy sauce, rice vinegar, garlic, ginger, and egg white if using.Mix well to coat. Let sit 20–30 minutes while you prep the sauce and oil.
Make the sauce. In a small saucepan, combine gochujang, ketchup, honey, soy sauce, rice vinegar, garlic, ginger, and sesame oil. Bring to a gentle simmer over low heat for 2–3 minutes.Add a splash of water if it seems too thick. Turn off heat and set aside.
Heat the oil. Fill a heavy pot with about 2 inches of oil. Heat to 325°F (163°C) for the first fry.Keep a thermometer clipped to the side if you have one.
Prepare the coating. In a shallow bowl, mix potato starch, baking powder, and garlic powder. Dredge each piece of chicken, pressing so a thin, even layer sticks. Shake off excess.
First fry (cook-through stage). Working in batches, fry chicken at 325°F for 6–8 minutes (wings) or 7–9 minutes (thigh pieces) until pale golden.Don’t crowd the pot. Transfer to a wire rack set over a sheet pan. Let rest 10 minutes.
Raise the heat for the second fry. Increase oil temperature to 375°F (190°C).This high heat crisps the exterior fast without drying the meat.
Second fry (crisping stage). Fry the chicken again in batches for 2–3 minutes, until deep golden and audibly crisp. Drain on the rack.
Sauce carefully. Warm the sauce if needed. You have two options:
- Toss to coat: For saucy chicken, place pieces in a large bowl, add sauce, and toss quickly.
- Brush or drizzle: For maximum crunch, brush or drizzle a thinner layer so the crust stays snappy.
Finish and serve. Sprinkle with sesame seeds and green onions.Serve immediately with pickled radish and cold beer or sparkling water.

Storage Instructions

Refrigerate: Cool completely, then store in an airtight container for up to 3 days. Keep sauce separate if possible.
Reheat: Re-crisp in a 400°F (205°C) oven or air fryer for 8–12 minutes. Avoid the microwave—it softens the crust.
Freeze: Freeze unsauced pieces on a sheet pan until solid, then bag for up to 2 months.Reheat from frozen at 400°F for 15–20 minutes.
Make-ahead tip: Complete the first fry earlier in the day. Do the second fry and sauce right before serving.

Benefits of This Recipe

Incredible texture: A glassy, crunchy shell that holds up to sauce.
Customizable heat: Adjust gochujang and honey to find your sweet spot.
Affordable crowd-pleaser: Wings or thighs stretch easily for parties.
No special gear: A pot, tongs, and a thermometer are all you need.
Reliable method: Timing and temps give repeatable, restaurant-level results.

What Not to Do

Don’t skip the resting time between fries. It helps steam escape and improves crispness.
Don’t use all-purpose flour alone. It fries denser and gets soggy faster.
Don’t overcrowd the pot. The oil temperature will drop and the coating turns greasy.
Don’t sauce too early. Wait until right before serving to keep the crust snappy.
Don’t guess oil temperature. Use a thermometer for consistent results.

Recipe Variations

Soy Garlic: Swap gochujang sauce for a glaze of soy sauce, honey, minced garlic, a splash of mirin, and a knob of butter.Simmer to thicken and toss.
Honey Butter: Melt butter with honey, a pinch of salt, and a dash of lemon juice. Toss for a sweet, glossy finish.
Extra Hot: Add gochugaru (Korean chili flakes) or a bit of cayenne to the sauce, and a pinch to the starch coating.
Lemongrass Ginger: Add finely minced lemongrass and extra ginger to the marinade for a bright twist.
Gluten-Free: Use tamari instead of soy sauce. Potato starch is naturally gluten-free.
Air Fryer Hack: Lightly oil-coated chicken and air fry at 375°F for 18–22 minutes, flipping halfway.Toss in warm sauce. Not as shatter-crisp as deep-fried, but still very good.

FAQ’s

Can I use chicken breast?

Yes, but cut it into 1.5–2-inch chunks and keep a close eye on timing so it doesn’t dry out. Thighs and wings stay juicier and are more forgiving.

What if I can’t find gochujang?

Use a mix of ketchup, a touch of miso or soy sauce, honey, and a bit of sriracha.

It won’t be the exact flavor, but you’ll get a similar sweet-spicy profile.

Why potato starch instead of cornstarch?

Potato starch fries up lighter and crunchier with a more delicate, “glassy” crackle. Cornstarch works in a pinch, just slightly less shattering.

How do I keep the coating from falling off?

Pat the chicken dry before marinating, use the egg white for extra adhesion, and press the starch on firmly. Let the coated pieces rest 5 minutes before frying.

What oil should I use?

Choose a high smoke point, neutral oil like canola, peanut, or vegetable oil.

Avoid olive oil for deep frying.

Can I make it less spicy?

Absolutely. Reduce the gochujang and increase honey or ketchup slightly. You can also serve the sauce on the side for dipping.

How do I know the chicken is done?

Use a thermometer—internal temp should reach 165°F (74°C).

The first fry cooks it through; the second fry is for color and crunch.

Why double-fry instead of a single long fry?

The first fry cooks and sets the crust. Resting lets steam escape. The second, hotter fry rapidly crisps the exterior without overcooking the meat.
