Tips for Success
- Pound the chicken evenly so it cooks at the same rate.
- Marinate for at least 30 minutes, or preferably several hours.
- Cornstarch is key to creating an especially light and crispy crust.
- Make sure the frying oil is fully heated before adding the chicken.
- Don’t overcrowd the pan, as this can lower the oil temperature.
- For an extra-crispy coating, fry the chicken twice.
- Toss the fried chicken in the glaze just before assembling.
- Keep the glaze warm but don’t boil it for too long.
- Toast the buns lightly so they hold up to the juicy chicken and sauce.
- Add the pickles just before serving for a refreshing crunch.
Instructions
Step 1: Marinate the Chicken
- Place the chicken thighs in a bowl.
- Add the buttermilk, garlic powder, smoked paprika, salt, and black pepper.
- Mix until the chicken is completely coated.
- Cover and refrigerate for at least 30 minutes, preferably 2–4 hours.
Step 2: Prepare the Breading
- In a large bowl, whisk together the flour, cornstarch, baking powder, garlic powder, and onion powder.
- Remove the chicken from the marinade, allowing excess buttermilk to drip off.
- Dredge each piece thoroughly in the flour mixture.
- Press the coating firmly onto the chicken for a thicker crust.
Step 3: Fry the Chicken
- Heat vegetable oil to about 350°F (175°C) in a deep, heavy-bottomed pot.
- Carefully add the chicken pieces without overcrowding the pot.
- Fry for approximately 5–7 minutes per side, depending on thickness, until deeply golden and the internal temperature reaches 165°F (74°C).
- Transfer to a wire rack to drain.
Step 4: Make the Gochujang Glaze
- Add Gochujang, honey or brown sugar, soy sauce, rice vinegar, sesame oil, and minced garlic to a saucepan.
- Heat over medium-low heat.
- Stir for 2–3 minutes until smooth and glossy.
- Remove from the heat.
Step 5: Glaze the Chicken
- Place the crispy chicken into a large bowl.
- Pour the warm Gochujang glaze over the chicken.
- Toss gently until evenly coated while keeping as much crunch as possible.
Step 6: Toast the Buns
- Lightly butter the cut sides of the brioche buns.
- Toast them in a skillet over medium heat until golden brown.
Step 7: Assemble
- Spread mayonnaise over the bottom bun.
- Place the glazed crispy chicken on top.
- Add a slice of melted cheese.
- Top with quick-pickled cucumber slices.
- Sprinkle with sesame seeds and chopped green onions.
- Add more mayonnaise or Gochujang sauce if desired.
- Finish with the toasted top bun.

Conclusion
This Korean Fried Chicken Sandwich is a delicious combination of Korean fried chicken and the classic crispy chicken sandwich. The crunchy chicken, spicy-sweet Gochujang glaze, creamy mayo, refreshing pickles, and toasted brioche create a restaurant-quality sandwich that’s perfect for an indulgent homemade meal.
Recommendation
Serve with Korean pickled radish, crispy fries, sweet potato fries, or a fresh cabbage slaw. For an extra spicy version, mix a little Gochujang into the mayonnaise before spreading it on the bun.
Embracing Healthful Indulgence
Making this sandwich at home lets you control the amount of sauce, salt, and oil while using fresh chicken and vegetables. For a lighter version, air-fry or oven-bake the breaded chicken instead of deep-frying and serve it with extra cucumber or cabbage. The result can still deliver plenty of crunch and flavor while making the meal more balanced.
