Save Pin My tiny Tokyo apartment kitchen had barely three feet of counter space, but the smell of panko toasting in hot oil made it feel like the most luxurious restaurant in the city. I'd stumble home from work, exhausted and craving something that felt like a hug in food form, and chicken katsu never disappointed. The first time I attempted it, I burned the first batch because I was too impatient with the oil temperature. Now I know better, and that first bite through the shattering crust into juicy meat still transports me back to those cramped but wonderful evenings.
Last winter my sister came over during a particularly rough week and I made a triple batch. We sat at the kitchen table in our sweatpants, dipping crispy chicken into sauce and talking until midnight. She texted me the next day saying it was the best meal shed had in months. Sometimes the simplest food creates the strongest memories.
Ingredients
- 4 boneless skinless chicken breasts: Pounding them to even thickness ensures they cook through before the crust burns
- 1/2 teaspoon salt and 1/4 teaspoon black pepper: Simple seasoning that lets the chicken shine through all that crunch
- 1/2 cup all-purpose flour: The first layer that helps the egg coating stick
- 2 large eggs plus 1 tablespoon water: The water thins the egg slightly for an even coat
- 1 1/2 cups panko breadcrumbs: These Japanese breadcrumbs create that signature airy crunch regular crumbs cant match
- 1 cup vegetable oil: You need enough for shallow frying about half an inch deep in the pan
- 1/4 cup ketchup plus 2 tablespoons Worcestershire sauce: The base of your tangy homemade tonkatsu sauce
- 1 tablespoon soy sauce and 1 tablespoon mirin: Deep umami and subtle sweetness to balance the tang
- 1 teaspoon Dijon mustard and 1 teaspoon sugar: These two ingredients tie all the sauce flavors together
Instructions
- Pound the chicken:
- Place each breast between plastic wrap and use a meat mallet or heavy pan to pound to even thickness about 1/2 inch thick. Season both sides generously with salt and pepper.
- Set up your breading station:
- Arrange three shallow dishes in a row. Put flour in the first, beat the eggs with water in the second, and pour panko into the third.
- Coat the chicken:
- Dredge each piece in flour shaking off excess, dip in egg mixture letting extra drip off, then press firmly into panko to coat thoroughly.
- Heat your oil:
- Pour oil into a large skillet and heat over medium until it shimmers. If you have a thermometer aim for 340°F.
- Fry to perfection:
- Carefully place chicken in the hot oil working in batches so you dont crowd the pan. Fry 3 to 4 minutes per side until deep golden brown and cooked through.
- Make the sauce:
- While chicken drains on a wire rack whisk together ketchup Worcestershire soy sauce mirin mustard and sugar until smooth.
- Serve it up:
- Slice the chicken into strips and serve over rice with that homemade sauce shredded cabbage and lemon wedges on the side.

Save Pin My friend Hiroshi told me his grandmother used to make katsu for special occasions and the whole house would smell like frying oil and joy. Now whenever I make it for my own family on Tuesday nights I understand exactly what he meant.
Getting the Perfect Crunch
That rest period after breading isnt just a suggestion. Letting the panko settle helps it adhere better so you dont lose half your crust in the oil. I also learned to press the breadcrumbs on firmly rather than lightly sprinkling them. The difference is night and day.
Sauce Swaps and Variations
Sometimes I add a squirt of sriracha to the tonkatsu sauce when I want extra heat. My husband likes his with a splash of rice vinegar for more tang. The base recipe is forgiving and welcomes your personal touches.
Make Ahead Strategies
You can bread the chicken hours ahead and store it layered between parchment paper in the fridge. The sauce actually improves after a day in the refrigerator as the flavors meld together. When youre ready to eat just fry and serve.
- Double the sauce and keep it in a jar for quick meals
- Fried cutlets reheat surprisingly well in a hot oven
- Leftovers make incredible katsu sandwiches the next day

Recipe FAQs
- → What makes chicken katsu different from regular fried chicken?
Chicken katsu uses panko breadcrumbs instead of traditional flour or cornflake coatings. Panko creates a lighter, airier crunch that stays crispy longer. The meat is pounded to an even thickness for uniform cooking, and the dish is traditionally served with a specialized tangy-sweet tonkatsu sauce rather than gravy or hot sauce.
- → Can I bake chicken katsu instead of frying?
Yes, you can bake the breaded cutlets at 425°F (220°C) for 20-25 minutes, flipping halfway through. Lightly spray with cooking oil before baking to help achieve golden color. While baked versions won't be quite as crispy as fried, they still offer satisfying crunch with less oil.
- → What can I use instead of panko breadcrumbs?
While panko provides the authentic texture, you can substitute with crushed cornflakes, regular breadcrumbs mixed with crushed crackers, or even crushed potato chips. These alternatives will still create a crispy coating, though the texture will be denser than traditional panko.
- → How do I store and reheat leftover katsu?
Store cooled cutlets in an airtight container in the refrigerator for up to 3 days. To reheat, place in a 375°F (190°C) oven for 10-12 minutes or air fry at 350°F (175°C) for 5-7 minutes. Avoid microwaving as it makes the breading soggy. For best results, freeze uncooked breaded cutlets between parchment paper for up to 1 month.
- → Is tonkatsu sauce the same as barbecue sauce?
No, tonkatsu sauce has a distinct flavor profile. It combines ketchup, Worcestershire sauce, soy sauce, mirin, mustard, and sugar for a complex umami-rich taste that's sweeter and fruitier than American barbecue sauce. You can find bottled tonkatsu sauce in Asian markets, but this homemade version tastes fresher and allows you to adjust the sweetness.
