Ingredients
- 2 chicken breasts
- 50g plain flour
- 75g panko breadcrumbs
- 2 eggs
- 3 tbsp chilli oil
- 500ml vegetable oil
- 4 tbsp kewpie mayonnaise (or regular mayonnaise)
- 3 tbsp kimchi, roughly chopped, plus extra to serve
- 1 large ciabatta loaf, halved and toasted
- 1 Sweet Gem lettuce, thinly sliced
- Small handful of chives, finely chopped
- ½ lemon, cut into wedges
Instructions
- Step 1: Butterfly the chicken breasts by slicing into one side and opening them like a book. Cover with baking parchment and bash with a rolling pin until they are 1-2cm thick.
- Step 2: Set up a breading station with flour (seasoned with salt and pepper) on one plate, panko breadcrumbs on a second plate, and whisked eggs with 1 tbsp chilli oil in a shallow bowl.
- Step 3: Coat each chicken breast first in flour, then dip in the egg mixture, and finally coat evenly with the breadcrumbs. Place the breaded chicken on a wire rack and repeat with the second breast.
- Step 4: Heat vegetable oil in a frying pan over medium-high heat until hot (180°C or bubbles form around a test bread piece). Fry the chicken breasts for 3 minutes on each side until golden and cooked through.
- Step 5: Transfer the cooked chicken to kitchen paper and brush with the remaining 2 tbsp chilli oil. Season lightly with salt and pepper.
- Step 6: Mix the mayonnaise with chopped kimchi to make kimchi mayo. Season to taste.
- Step 7: Spread the kimchi mayo on one side of the toasted ciabatta halves. Layer with the crispy chicken, extra kimchi if desired, sliced lettuce, and chopped chives.
- Step 8: Squeeze lemon wedges over the top for added brightness. Cut the sandwich in half and serve immediately.
Tips & Variations
- For extra crunch, use fresh panko breadcrumbs rather than pre-packaged ones.
- Substitute chicken thighs for a juicier, more flavorful option.
- Add sliced cucumber or pickled radish for extra freshness and texture.
- If you prefer less heat, reduce the amount of chilli oil or omit it from the egg wash.
- Use a grill instead of frying for a lighter version.
Storage
Store leftover chicken and kimchi mayo separately in airtight containers in the refrigerator for up to 2 days. Reheat the chicken in a hot oven or toaster oven to retain crispiness. Assemble the sandwich just before serving to keep the bread from becoming soggy.

FAQs
Can I make this sandwich vegetarian?
Yes, you can substitute the chicken with crispy fried tofu or a plant-based chicken alternative, using the same breading and frying method.
What can I use if I don’t have kewpie mayonnaise?
Regular mayonnaise works well as a substitute. Adding a bit of rice vinegar or a small dash of soy sauce can mimic the umami flavor of kewpie mayo.

Ingredients
For the Chicken
- 2 chicken breasts
- 50g plain flour
- 75g panko breadcrumbs
- 2 eggs
- 3 tbsp chilli oil
- 500ml vegetable oil (for frying)
For the Kimchi Mayo and Assembly
- 4 tbsp kewpie mayonnaise or regular mayonnaise
- 3 tbsp kimchi, roughly chopped, plus extra to serve
- 1 large ciabatta loaf, halved and toasted
- 1 Sweet Gem lettuce, thinly sliced
- Small handful of chives, finely chopped
- ½ lemon, cut into wedges
Instructions
- Prepare the Chicken: Butterfly the chicken breasts by slicing into one side and opening them like a book. Place them between baking parchment and gently bash with a rolling pin until they are 1-2cm thick. This ensures even cooking and a tender texture.
- Set up the Breading Station: Place the plain flour on one plate and season it with salt and pepper. On a second plate, spread out the panko breadcrumbs. In a shallow bowl, whisk together the eggs with 1 tablespoon of the chilli oil to form the egg wash.
- Bread the Chicken: Dip each chicken breast into the seasoned flour, coating completely. Then dip into the egg wash, ensuring full coverage. Finally, press both sides into the panko breadcrumbs until fully coated. Set the breaded chicken breasts aside on a wire rack.
- Fry the Chicken: Heat the vegetable oil in a frying pan over medium-high heat until it reaches 180°C or bubbles form when testing with a small piece of bread. Carefully add the chicken breasts one at a time, frying for about 3 minutes on each side or until golden brown and cooked through. Transfer the cooked chicken onto kitchen paper to drain excess oil.
- Finish Chicken with Chilli Oil: Brush the fried chicken breasts with the remaining 2 tablespoons of chilli oil and lightly season with salt and pepper. This adds an extra layer of spicy flavor and gloss.
- Make Kimchi Mayo: In a bowl, mix the mayonnaise with the roughly chopped kimchi. Season to taste. This spicy, tangy mayo is key to the sandwich’s vibrant flavor.
- Assemble the Sandwich: Spread the kimchi mayo generously over one side of the toasted ciabatta loaf. Layer the coated chicken breast on top, followed by additional kimchi if desired, sliced Sweet Gem lettuce, and finely chopped chives. Optionally squeeze a wedge of lemon over the filling for a fresh citrus kick.
- Serve: Cut the sandwich in half to serve. This recipe makes a hearty sandwich perfect for lunch or a casual dinner.
Notes
- Ensure the oil is hot enough before frying to get a crispy coating without absorbing too much oil.
- Use Sweet Gem lettuce or any mild lettuce for a fresh crunch without overpowering the flavors.
- Kewpie mayonnaise gives a richer, creamier flavor but regular mayo works well too.
- The lemon wedge adds a bright, zesty contrast to the rich fried chicken and mayo.
- Can be served with extra kimchi on the side for kimchi lovers.
