Korean fried chicken is a beloved dish known for its ultra-crispy, almost shatteringly crunchy exterior and a glossy, sweet-and-spicy sauce that clings to every piece. Unlike American fried chicken, it’s often double-fried, which removes excess moisture and creates a thin, lacquered crust that stays crisp even after being coated in sauce. This guide walks you through making it at home, from the double-fry technique to the gochujang-based glaze, so you can achieve that signature Korean flavor and texture in your own kitchen.
What You’ll Need
- 2 lbs (900 g) chicken wings or drumettes (or a mix of both)
- 1 tbsp (15 ml) rice wine or mirin (optional, for marinating)
- 1 tsp (5 g) grated ginger
- 1 tsp (5 g) grated garlic
- 1/2 tsp (2.5 g) salt
- 1/2 tsp (2.5 g) black pepper
- 1/2 cup (60 g) potato starch or cornstarch
- 1/4 cup (30 g) all-purpose flour
- 1 tsp (5 g) baking powder
- 1/2 cup (120 ml) ice-cold water
- 1 egg (optional, for extra richness)
- Vegetable oil, for deep-frying (about 4 cups / 1 L)
- For the sauce: 3 tbsp (45 g) gochujang (Korean red chili paste)
- 2 tbsp (30 ml) soy sauce
- 2 tbsp (30 ml) rice vinegar
- 2 tbsp (30 g) brown sugar or honey
- 1 tbsp (15 ml) sesame oil
- 1 tsp (5 g) minced garlic
- 1 tsp (5 g) grated ginger
- 2 tbsp (30 g) gochugaru (Korean red pepper flakes) – optional, for extra heat
- 1 tbsp (15 ml) water
- For garnish: toasted sesame seeds, sliced green onions
Step-by-Step
- Prep the chicken: Rinse the chicken wings and pat them completely dry with paper towels. In a large bowl, combine the chicken with rice wine (if using), grated ginger, grated garlic, salt, and pepper. Toss to coat, then cover and refrigerate for at least 30 minutes, or up to 2 hours. This step adds flavor and helps tenderize the meat.
- Make the batter: In a separate bowl, whisk together the potato starch, all-purpose flour, baking powder, and ice-cold water. If using the egg, beat it in. The batter should be thin and runny, similar to a crepe batter. If it’s too thick, add a little more cold water.
- Heat the oil: In a deep, heavy-bottomed pot (like a Dutch oven) or a deep fryer, heat the vegetable oil to 350°F (175°C). Use a deep-fry thermometer to ensure accuracy. The oil should be about 2 inches (5 cm) deep.
- First fry: Dip each piece of chicken into the batter, letting the excess drip off, then carefully place it into the hot oil. Fry in batches, making sure not to overcrowd the pot (this lowers the oil temperature). Fry for about 8-10 minutes, until the chicken is cooked through and lightly golden. The internal temperature of the chicken should reach 165°F (74°C) as measured with a food thermometer, per USDA FSIS safe minimum. Remove with a slotted spoon and drain on a wire rack (not paper towels, which can make the crust soggy).
- Second fry: Increase the oil temperature to 375°F (190°C). Return the fried chicken to the hot oil in batches and fry for another 4-5 minutes, until deep golden brown and very crispy. This second fry removes excess oil and creates the shatteringly crisp crust. Drain on a clean wire rack.
- Make the sauce: While the chicken is frying, combine all the sauce ingredients (gochujang, soy sauce, rice vinegar, brown sugar or honey, sesame oil, minced garlic, grated ginger, gochugaru if using, and water) in a small saucepan. Cook over medium heat, stirring constantly, until the sugar dissolves and the sauce thickens slightly, about 2-3 minutes. Remove from heat.
- Coat the chicken: Place the double-fried chicken in a large bowl. Pour the warm sauce over it and toss gently with tongs until every piece is evenly coated. Alternatively, you can brush the sauce on for a lighter coating.
- Serve immediately: Transfer the glazed chicken to a serving platter and sprinkle with toasted sesame seeds and sliced green onions. Serve hot with rice, pickled radishes, or beer. The chicken is best eaten right away, as the sauce will eventually soften the crispiness.
Common Mistakes
- Skipping the double fry: The double fry is not optional. The first fry cooks the chicken through, while the second fry at a higher temperature creates the crispy exterior. Skipping it results in a soggy, oily crust.
- Using warm water in the batter: The batter must be ice-cold. Warm water activates the gluten in the flour, making the crust tough and dense instead of light and crispy.
- Overcrowding the pot: Adding too many pieces at once drops the oil temperature, leading to greasy, undercooked chicken. Fry in small batches.
- Draining on paper towels: Paper towels trap steam and make the crust soggy. Use a wire rack set over a baking sheet to allow air circulation.
- Adding sauce to cold chicken: The sauce should be warm and the chicken hot off the fryer. If the chicken cools, the sauce won’t adhere properly and the crust may become chewy.
Tips
- Use potato starch: Potato starch (or cornstarch) gives a lighter, crispier crust than all-purpose flour alone. It also has a neutral flavor that lets the sauce shine.
- Rest the batter: Let the batter rest for 10-15 minutes after mixing. This allows the flour to hydrate fully and produces a more even coating.
- Keep the oil temperature steady: Use a deep-fry thermometer and adjust the heat between batches to maintain the correct temperature. This is key to even cooking and crispiness.
- Double coat for extra crunch: For an even thicker crust, dip the chicken in the batter, then in a light dusting of potato starch before frying.
- Make it spicy: Adjust the gochugaru amount to control the heat. For a milder version, reduce or omit it. For a sweeter sauce, add more honey or brown sugar.
Troubleshooting
- Chicken is not crispy: This usually means the oil wasn’t hot enough, or the chicken was overcrowded. Ensure the oil is at 350°F (175°C) for the first fry and 375°F (190°C) for the second. Also, make sure the chicken is completely dry before battering.
- Batter falls off: The chicken might be too wet, or the batter is too thin. Pat the chicken dry thoroughly and add a little more flour to the batter to thicken it slightly.
- Chicken is greasy: The oil temperature dropped too low, causing the chicken to absorb oil. Fry in smaller batches and allow the oil to return to temperature between batches.
- Sauce is too thick or too thin: If the sauce is too thick, add a splash of water. If it’s too thin, simmer it longer to reduce. Adjust the consistency to your liking.
- Sauce is too spicy: Add a tablespoon of honey or a little more brown sugar to balance the heat. You can also add a splash of ketchup for sweetness.
Frequently Asked Questions
Q: Can I use chicken breast instead of wings?
A: Yes, but adjust cooking time. Cut the breast into 1-inch (2.5 cm) chunks and fry for 6-8 minutes in the first fry, then 3-4 minutes in the second. Ensure the internal temperature reaches 165°F (74°C).
Q: Can I make Korean fried chicken gluten-free?
A: Yes. Use gluten-free all-purpose flour and ensure your gochujang and soy sauce are gluten-free (tamari works). Replace the flour with an equal amount of gluten-free flour blend.
Q: How do I store leftovers?
A: Store in an airtight container in the refrigerator for up to 3 days. To reheat, place in a 375°F (190°C) oven for 5-7 minutes to regain crispiness. Avoid microwaving, which makes it soggy.
Q: Can I use a different type of chili paste?
A: Gochujang is essential for the authentic flavor. A substitute would be a mix of Sriracha and a little miso paste, but it will not taste the same. For a non-spicy version, use a mixture of soy sauce, honey, and garlic.
Q: Why is my chicken not cooked through after the first fry?
A: The oil temperature may be too low. Use a thermometer and maintain 350°F (175°C). Also, ensure the chicken pieces are uniform in size so they cook evenly. Check with a food thermometer.
Q: Can I prepare the sauce ahead of time?
A: Yes, the sauce can be made up to 3 days ahead and stored in the refrigerator. Reheat it gently before tossing with the hot chicken.
