This Spicy Fried Chicken Burger is crispy, juicy, and loaded with bold flavor! Boneless chicken thighs are coated in a spicy seasoned batter, dipped in ice water for an extra crunchy crust, and fried until golden brown. Serve the crispy chicken on toasted burger buns with lettuce, cheese, and a creamy spicy sauce for an amazing homemade chicken burger.
Mix egg whites, 1 tablespoon flour, 2 tablespoons gochugaru, 1 tablespoon paprika, 1 tablespoon garlic powder, 1/2 teaspoon salt, and 1/2 teaspoon sugar in a bowl.
Add the chicken thighs and coat them well in the marinade. Cover and refrigerate for at least 3 hours or overnight.
In a separate bowl, mix 2 cups flour, 2 tablespoons gochugaru, 1 tablespoon paprika, 1 tablespoon garlic powder, onion powder, baking powder, 1/4 teaspoon salt, and 1/2 teaspoon sugar.
In a small bowl, mix Japanese mayo, sweet chili sauce, Sriracha, soy sauce, vinegar, and chili flakes to make the sauce.
Coat one piece of marinated chicken in the dry flour mixture, dip it in ice cold water for 5 seconds, then let the excess water drip off for 10 seconds.
Coat the chicken in the dry flour mixture again. Repeat the ice water dip and flour coating one more time, then let the coated chicken rest for 5 minutes.
Heat oil in a deep frying pan or pot over medium heat. Carefully add the chicken and fry for 10 to 15 minutes, or until golden brown, crispy, and fully cooked.
Remove the chicken from the oil and place it on a wire rack or paper towel-lined plate. For extra crispy chicken, fry it again for 5 to 8 minutes.
Sprinkle the hot chicken with a pinch of salt and extra gochugaru, if desired. Toast the burger buns.
Spread the spicy sauce on both sides of each bun, then add crispy chicken, cheese, lettuce, and the top bun. Serve immediately.
Notes
Boneless chicken thighs work best for this recipe because they stay juicy after frying. If the chicken pieces are too large for the buns, cut them smaller before marinating.
The ice water dip helps create a very crispy coating. Be gentle when dipping the chicken so the flour coating stays on.
