This Air Fryer Chicken Katsu uses butterflied boneless chicken thigh, seasoned, coated in panko and air-fried at 200°C (390°F) for about 14 minutes, flipped halfway. It is served with shredded cabbage, cherry tomatoes, lemon and a creamy, mildly spicy gochujang mayo, ready in about an hour, including marinating time.
I love chicken katsu for the crust. Well-seasoned meat, a crunchy panko coating, fresh cabbage and tomatoes on the side, and a sauce that pulls it all together. There is no deep frying here and no pot of oil to clean up, just an air fryer and a good spray of oil.
The oil spray matters more than you might expect. Panko has no fat of its own, so any part the spray misses stays pale and dry instead of turning golden. Spray both sides generously before cooking, and if you see white patches when you flip, spray those spots again.
The sauce is Japanese mayo with lemon juice, honey and a little gochujang, which gives it a gentle heat without taking over. It goes well with the katsu, and it is just as good on the vegetables, especially the cherry tomatoes.

Ingredient Notes
Chicken thigh: Boneless thigh, butterflied so it is thin and even. It is more forgiving than breast in the air fryer.
Ajinomoto: MSG seasoning. A small pinch rounds out the salt and pepper. Leave it out if you prefer.
Panko: Japanese breadcrumbs, coarser than regular breadcrumbs, which is what gives katsu its craggy crust.
Gochujang: Korean fermented chili paste. Half a teaspoon makes the sauce mildly spicy; add more if you like heat.
Japanese mayo: Richer and slightly tangier than regular mayo. Regular mayo works too.

Chicken Katsu with Gochujang Mayo
Ingredients
Equipment
Method
- Butterfly the chicken thigh: slice through the thick part and open it like a book so it is thin and even. Cut it into two pieces.
- In a small bowl, mix the salt, Ajinomoto, black pepper and white pepper. Mixing first helps the seasoning spread evenly. Sprinkle it over both sides of the chicken, rub it in, and rest for 30 minutes to 1 hour.
- Set up the flour, beaten egg and panko. Keep one hand dry for the flour and panko, and use the other for the egg. Coat each piece in flour and shake off the excess, dip in egg, then coat in panko, patting gently so it covers every side.
- Spray both sides generously with oil. This is what turns the panko golden instead of pale and dry.
- Air fry at 200°C (390°F) for about 14 minutes, flipping at the 7 minute mark. If you see white patches or uneven colour when you flip, that part did not get enough oil, so give it another spray and continue air frying.
- While the chicken cooks, halve the cherry tomatoes and cut the lemon into wedges, saving some to juice for the sauce. Shred the cabbage as fine as you can.
- For the sauce, start with the garlic powder, onion powder and parsley, then add the Japanese mayo, lemon juice, honey and gochujang. Mix until smooth.
- If the katsu is not brown enough at the end, give it another 2 minutes. Do not go much longer, or the chicken starts to dry out.
- Plate the cabbage, tomatoes, katsu and a wedge of lemon, and serve with the gochujang mayo.

Notes
My two glass containers: the small one (left) and the large one (right). Serves: Two. I cut the thigh into one bigger piece for me and a smaller one for my daughter. Oil spray: There is no deep frying, but the panko does need a generous spray on both sides to brown. Doneness: Make sure the chicken is fully cooked with no pink left and the juices run clear (74°C / 165°F if you use a thermometer). Cabbage: For extra crispness, soak the shredded cabbage in cold water for a few minutes, then drain and dry it well.
Frequently Asked Questions
Can I use chicken breast instead of thigh?
Yes, but keep a close eye on the timing. Butterflied chicken breast cooks faster and dries out more easily than thigh, so start checking a few minutes early and take it out as soon as it reaches 165°F (74°C) inside and the crust is golden.
Why does my katsu have white patches?
Those spots did not get enough oil. Panko only browns where it is coated, so spray both sides generously before cooking, and when you flip the chicken, spray any pale areas again before it goes back in.
Can I make the sauce ahead of time?
Yes. Mix the gochujang mayo and keep it covered in the fridge until you are ready to eat. Give it a stir before serving.
How do I butterfly a chicken thigh?
Lay the boneless thigh skin side down. Find the thickest part and slice into it from the side, stopping before you cut all the way through, then open it out like a book. Aim for an even thickness all over so the whole piece cooks at the same speed and none of it dries out before the thick part is done.
How do I know the chicken katsu is cooked through?
The surest way is an instant-read thermometer in the thickest part. Chicken is safe at 74°C (165°F), the temperature in the FoodSafety.gov safe minimum internal temperature chart. Without a thermometer, cut into the thickest piece: the meat should be white all the way through with clear juices, not pink.
