Instructions

1. 1

   Mix wet batter

   In a large bowl, whisk the egg whites, 1 tablespoon of flour, 2 tablespoons of gochugaru, paprika, garlic powder, salt, sugar and 710 ml of ice-cold water until smooth and combined.

2. 2

   Mix dry coating

   In another large bowl, combine the 250 g of flour, 2 tablespoons of gochugaru, paprika, garlic powder, optional onion powder, baking powder, salt and sugar. Mix thoroughly so the seasonings are evenly distributed.

3. 3

   Coat the chicken

   Pat the chicken thighs dry with paper towels. Dip each one in the wet batter, let the excess drip off, then dredge it in the dry mixture, pressing the coating gently onto all sides.

4. 4

   Fry until crisp

   Heat oil in a deep fryer or heavy-based pot to 175°C. Carefully lower in the coated thighs and fry for about 6–8 minutes, until cooked through, deep golden and crisp. Drain on paper towels.

5. 5

   Stir together sauce

   In a small bowl, mix the Japanese mayonnaise, sweet chilli sauce, Sriracha, light soy sauce, rice vinegar and chilli flakes until smooth.

6. 6

   Build the burgers

   Slice the buns and toast them lightly if you like. Spread a generous amount of sauce on each bottom half, add lettuce, a crispy chicken thigh and an American cheese slice, then top with the bun. Serve straight away.

What is a spicy crispy chicken burger?

This burger brings together American-style fried chicken and Korean chilli flavours, especially the fruity warmth of gochugaru. The result is a crunchy chicken sandwich with a creamy, spicy sauce rather than a traditional grilled burger.

The method builds flavour in two stages: the chicken sits in a seasoned wet batter, then gets a spiced flour coating. That layered approach gives the thighs a lively seasoning and a crisp exterior.

Nutrition and macros by portion

The nutrition label shows one serving as written: 900 calories, 44g protein, 78g carbs, 43g fat.

The bun and flour coating provide most of the carbohydrates, while the chicken thighs contribute much of the protein. Frying oil, mayonnaise and cheese account for much of the fat; lettuce adds freshness with little energy. Serve with a generous side of salad or vegetables to round out the plate.

The chicken and its coating

Chicken thighs: boneless thighs stay juicy during frying and fit neatly into buns. Pat them dry first so the wet batter clings more evenly.

Gochugaru: Korean chilli flakes bring colour and a rounded chilli flavour to both coatings. The optional onion powder adds another savoury note to the dry mix.

Getting a craggy crust

Wet batter: whisk until smooth so there are no pockets of flour or seasoning. Let excess batter drip off each thigh before dredging; this helps avoid a heavy, gummy layer.

Dry mix: press the flour mixture gently onto all sides of the chicken. Handle each coated thigh carefully as you move it to the fryer so the crust stays attached.

Frying and checking doneness

Oil temperature: heat the oil to 175°C before adding the chicken. If the oil is not hot enough, the coating can absorb more oil instead of crisping promptly.

Doneness: fry for about 6–8 minutes, as directed, until the coating is deep golden and crisp and the chicken is cooked through. The exact time can vary with thigh size, so check the thickest part rather than relying on colour alone.

Balancing the sauce

Creamy base: Japanese mayonnaise gives the sauce body, while sweet chilli sauce adds sweetness and Sriracha supplies extra heat. Soy sauce and vinegar make the flavour more savoury and tangy.

Chilli flakes: these add another layer of spice and texture. Stir the sauce until evenly blended so every burger gets a balanced coating.

Assembling and serving

Bun and lettuce: lightly toasting the buns is optional, but it gives them a sturdier surface for the sauce. Lettuce adds a fresh contrast to the hot chicken and creamy dressing.

Cheese: add the American cheese slice on top of the hot chicken, then close the burger with the top bun. Serve immediately to enjoy the coating at its crispest.

Recipe notes & tips

• Measure the oil temperature with a thermometer before frying the first thigh.
• Keep the ice water cold as you mix the wet batter.
• Use a wide bowl for the dry mix so each thigh can be coated without spilling flour.
• Drain fried chicken on paper towels before assembling the burgers.
• Toast the buns lightly if you want them to hold the sauce more firmly.

Variations

• Adjust the heat: use less Sriracha or chilli flakes in the sauce for a milder burger.
• Add pickles: tuck sliced pickles in with the lettuce for a sharp, tangy contrast.
• Swap the greens: use shredded cabbage instead of lettuce for extra crunch.
• Change the cheese: use another sliced cheese if American cheese is unavailable.
• Make it bun-free: serve the crispy chicken over lettuce with the sauce on the side.

Common mistakes to avoid

• Damp chicken: the batter may not cling as well; pat the thighs thoroughly dry first.
• Loose coating: flour can fall away during frying; press the dry mix gently onto every side.
• Cool oil: the crust may turn greasy; bring the oil back to 175°C before frying.
• Crowded pot: the oil temperature can drop; fry in batches if the thighs do not fit comfortably.
• Early assembly: steam softens the crust; build the burgers just before serving.

How to store

Store leftover fried chicken and sauce separately in airtight containers in the fridge for up to 3 days. Reheat the chicken in an oven or air fryer until hot and crisp, then assemble with fresh lettuce and buns; avoid storing assembled burgers if you want to preserve the texture.
