Air Fryer Chicken Katsu

If you want an easy weeknight dinner with a Japanese twist, this air fryer chicken katsu is it. It’s crispy panko on the outside, juicy chicken inside, and an easy katsu sauce you stir together in one bowl.

I make a lot of breaded chicken in the air fryer, so when I wanted to try chicken katsu, I figured it would work the same way, and it did. Panko is the secret to that crispy, golden crust, and the chicken stays tender and juicy in the middle. The best part is there’s way less oil than frying it on the stove, so no greasy mess to wipe down after.

The katsu sauce is my favorite part. It’s sweet and savory with a little bite from the Worcestershire, and you stir it together from a few things you probably already have. My kids actually eat it too, and they’re picky.

Serve it over rice with veggies, pile it on a sandwich, or slice it into crispy chicken fingers for dipping. There’s really no wrong way to eat this one.

Ingredients and why they work

Here is what goes into this air fryer chicken katsu recipe and why each piece matters. Full measurements are in the recipe card below.

• Boneless skinless chicken breasts – I slice them in half horizontally so they cook fast and stay even. Thin cutlets are the secret to juicy chicken that crisps up before it dries out.
• Salt and pepper – simple seasoning on the chicken itself so the flavor isn’t just on the crust.
• Eggs and water – the egg wash is the glue. The splash of water loosens it so it coats evenly and the panko grabs on.
• Panko bread crumbs – this is the whole reason katsu is so crispy. Panko is lighter and flakier than regular breadcrumbs, so it crisps up coarse and crunchy instead of dense.
• Ketchup, Worcestershire sauce, oyster or soy sauce, and brown sugar – this is the easy katsu sauce. Ketchup brings the tomato base, Worcestershire and oyster sauce add that deep savory kick, and brown sugar rounds it out with a little sweetness.

A quick note on the sauce. If you want to skip it, a store-bought bottle like Kikkoman katsu sauce works great too. I just think the homemade one tastes fresher and you control the sweetness.

How to Make Air Fryer Chicken Katsu 

Scroll down to the printable recipe card at the bottom of the post for exact measurements and storage tips.

Prep the chicken. Pat the chicken breasts dry, then slice each one in half horizontally to make four thin filets. If any spots are still thick, pound them to about a half inch so they cook evenly. Season both sides with salt and pepper.

Coat in panko, twice. Whisk the eggs and water in a wide, shallow bowl, and put the panko in a second bowl. Dip each piece in the egg wash, then press it into the panko so it sticks well. Then do it again. That double coat is what gives you that thick, crunchy katsu crust.

Air fry until golden. Preheat the air fryer to 350 degrees F and give the basket a spray of cooking spray. Lay the chicken in a single layer, spray the tops, and air fry for 16 to 18 minutes. Flip the pieces partway through and give them another light spray so the whole crust turns golden and crisp.

Make the katsu sauce. While the chicken cooks, whisk the ketchup, Worcestershire, oyster or soy sauce, and brown sugar together in a small bowl. Taste it and adjust. Add a little more sugar for sweet or a little more soy for salty.

Rest, then serve. Move the chicken to a cutting board and let it rest 5 minutes before slicing. That rest keeps the juices in. Slice it up and serve over rice with the katsu sauce.

My best tips for crispy katsu every time

• Don’t skip the oil spray. A light coat of cooking spray on both sides is what turns panko golden instead of dusty and pale. I spray again when I flip.
• Press the panko on hard. Loose crumbs fall off and make a mess in the basket. Really press each piece into the crumbs so the coating sticks.
• Don’t crowd the basket. Cook in a single layer with a little space between pieces. Crowd it and the steam gets trapped, so you lose that crunch. Work in batches if you need to.
• Use a thermometer. Pull the chicken when it hits 165 degrees F in the thickest part. The USDA lists 165 degrees F as the safe internal temperature for chicken (USDA Safe Minimum Internal Temperature Chart).
• Slice across for the look. Cutting the cutlet into strips before serving gives you that classic katsu plate and makes it easier for the kids to dip.

What to serve with air fryer chicken katsu

Traditionally katsu comes with a big scoop of steamed rice and some veggies, and that’s still my favorite way to plate it. Start with a batch of air fryer rice and add a green side like air fryer bok choy or air fryer broccoli. If you want something with a little sweet-savory edge, the sweet and spicy Brussels sprouts are so good next to the crispy chicken.

If you’re turning it into more of a fun plate, treat the katsu like crispy chicken fingers. I love it with air fryer potato wedges, air fryer sweet potato fries, or air fryer green bean fries for dipping. It also makes a really good sandwich piled on a soft bun with extra katsu sauce.

Storing and reheating

et leftover katsu cool, then store it in an airtight container in the fridge for up to 3 days. Keep the katsu sauce in its own container so the crust doesn’t get soggy.

To freeze, let the cooked katsu cool all the way, then freeze the pieces in a single layer before moving them to a freezer bag. They keep for up to 2 months. No need to thaw, just reheat from frozen.

To reheat and keep it crispy, pop the chicken back in the air fryer at 350 degrees F for 3 to 4 minutes until hot and crunchy again. From frozen, give it more like 8 to 10 minutes. The microwave works in a pinch, but you’ll lose the crunch, so I go back to the air fryer every time I can. Leftover sauce keeps in the fridge for about a week.

Frequently asked questions

What is chicken katsu made of?

Chicken katsu is a popular Japanese comfort food. Thin cutlets of chicken get dipped in egg, coated in panko, fried until golden, and served with a savory-sweet katsu sauce. You end up with chicken that’s crispy on the outside and tender and juicy inside.

Does panko work in the air fryer?

Yes! Panko is exactly what makes this air fryer chicken katsu so crispy. Press it on well so it sticks to the chicken, and give it a light spray of oil so it browns up golden instead of staying powdery.

What is the difference between chicken katsu and a chicken cutlet?

I like to think of them as cousins because both are thin, breaded, fried chicken. Katsu uses panko for that flaky, coarse crunch and comes with katsu sauce, while a western-style cutlet or schnitzel usually uses regular breadcrumbs. If you love this, my air fryer chicken cutlets are another easy one to try.

Can I make the katsu sauce ahead?

Absolutely. Whisk it together up to a week ahead and keep it in the fridge. The flavors settle in really nicely, just give it a stir before serving.
