Why you'll love it: shatteringly crisp · rich Japanese curry · ready in 55 minutes · make-ahead sauce.
I have a weakness for chicken katsu curry. Not a particularly dignified weakness, either. Put a plate of golden, crunchy chicken in front of me, accompanied by a generous helping of Japanese curry, and any intention of behaving with restraint disappears almost immediately.
It's the contrast that gets me.
That first crackle of panko beneath the knife, the tender chicken underneath, and a spoonful of thick, gently spiced curry that seems to find its way into every grain of rice. Add a few sharp Japanese pickles, and I'm a very happy man.

1 teaspoon Japanese soy sauce
1 teaspoon Worcestershire sauce, optional
For the Crispy Chicken Katsu
2 large boneless, skinless chicken breasts, about 8 ounces (225 g) each
½ cup (60 g) all-purpose flour
2 large eggs, lightly beaten
2 cups (100 g) Japanese panko breadcrumbs
½ teaspoon fine sea salt
¼ teaspoon freshly ground black pepper
Neutral vegetable oil, for shallow frying
To Serve
Steamed Japanese short grain rice
Japanese pickles, such as fukujinzuke, optional
Finely sliced scallions (spring onions), optional
Instructions
Soften the onion: Heat 1 tablespoon of vegetable oil in a medium saucepan over medium heat. Add the sliced onion and cook gently for approximately 8 to 10 minutes, stirring occasionally, until soft and lightly golden. You'll know it's right when the onion is soft, sweet and just turning golden at the edges.
Add the vegetables, garlic and ginger: Add the carrots and potatoes. Cook for another 3 minutes, stirring occasionally. Stir in the minced garlic and grated ginger. Cook for approximately 30 seconds, until fragrant.
Simmer with apple and stock: Add the grated apple, chicken stock, and water. Bring to a gentle boil, then reduce the heat and simmer for approximately 15 to 20 minutes, until the vegetables are tender. You'll know it's right when a knife slides easily through the potatoes and carrots.
Melt in the curry roux: Remove the saucepan from the heat. Break the Japanese curry roux into smaller pieces and stir into the hot liquid until completely dissolved. Taking the pan off the heat before adding the roux helps it melt smoothly, without lumps.
Thicken and season the curry: Return the saucepan to low heat and simmer gently for approximately 5 minutes, stirring frequently, until the sauce becomes thick and glossy. Add a little water if necessary to reach your preferred consistency. Stir in the soy sauce and optional Worcestershire sauce. Taste before adding any salt, as Japanese curry roux is already well seasoned. Keep the curry warm over very low heat while preparing the chicken. You'll know it's right when the sauce is thick and glossy, and clings to the back of a spoon. If the curry has become too thick, loosen it with a splash of water.
Prepare the chicken cutlets: Place the chicken breasts on a chopping board. Using a sharp knife, slice each breast horizontally into two thinner cutlets. Place each cutlet between two sheets of parchment paper and gently pound to an even thickness of approximately ⅜ inch (1 cm). Season both sides with salt and freshly ground black pepper.
Bread the chicken: Place the flour in a shallow dish, the beaten eggs in a second dish, and the panko breadcrumbs in a third. Working with one cutlet at a time, coat the chicken lightly in flour, shaking off any excess. Dip into the beaten egg, then press firmly into the panko breadcrumbs until evenly coated. Allow the coated chicken to rest for approximately 5 minutes while heating the oil. Don't skip the flour. It helps the egg cling to the chicken, and the egg holds the breadcrumbs in place.
Heat the oil: Pour enough vegetable oil into a large frying pan to reach a depth of approximately ⅜ inch (1 cm). Heat over medium heat until the oil reaches approximately 340°F (170°C). If the oil is smoking, it is too hot. Take it off the heat for a minute and let it settle back to 340°F (170°C).
Fry the chicken: Carefully add the chicken cutlets, working in batches if necessary. Fry for approximately 3 to 4 minutes on each side, until deeply golden and crisp. The thickest part of each cutlet should reach an internal temperature of 165°F (74°C). You'll know it's right when the crust is deep golden and the thickest part of each cutlet reads 165°F (74°C). Resist the temptation to fiddle with the chicken. Give the breadcrumbs time to colour before turning.
Rest on a wire rack: Transfer the cooked chicken to a wire rack set over a baking sheet. Allow it to rest for approximately 2 minutes before slicing. A wire rack lets the air circulate underneath. Paper towels trap steam and soften the crust.
Slice: Using a sharp knife, slice each cutlet into generous strips, keeping the crisp coating intact.
Serve: Spoon freshly steamed Japanese rice onto warm plates. Arrange the sliced chicken alongside the rice and ladle the curry sauce next to the chicken, leaving most of the crust beautifully crisp. Add Japanese pickles and finely sliced scallions if desired. Serve immediately.
Tips & Chef's Notes
Pound the chicken to an even thickness so it cooks through before the breadcrumbs become too dark.
Fry in batches. Overcrowding the pan drops the oil temperature and makes the coating greasy.
Taste the curry before adding salt. Different roux brands contain different amounts of salt and thickener.
Serve the curry alongside the chicken, not over it, so the crust stays crisp.
How to Store
Curry sauce: The curry sauce is an excellent candidate for making ahead. Prepare the sauce, cool it promptly, and refrigerate in an airtight container for up to three days. Warm it gently over low heat, adding a splash of water if it has thickened too much.
Chicken: The chicken is best cooked just before eating. You can coat the cutlets in flour, egg, and panko a few hours ahead and keep them covered in the refrigerator. Then all that's left is a few minutes in the frying pan.
Key Ingredients
Panko Breadcrumbs: Larger, lighter flakes that fry to a crust that is crisp without being heavy.
Chicken Breasts: Sliced into thin cutlets and pounded evenly so they cook quickly.
Japanese Curry Roux: A blend of spices, seasonings, fat and flour that makes the distinctive thick sauce.
Sweet Apple: Finely grated, for a gentle sweetness that balances the spices.
Ginger and Garlic: Warmth and fragrance at the base of the curry.
Low Sodium Chicken Stock: More savoury depth than water alone, without too much salt.
Yukon Gold Potatoes: They hold their shape in the sauce.
What Makes a Good Japanese Chicken Katsu Curry?
For me, it comes down to three things.
The chicken must be tender and juicy, with a coating that is properly crisp rather than greasy.
The curry should be rich and smooth, with enough sweetness to balance the spices but not so much that it tastes like dessert.
And the rice needs to be soft, warm, and ready to catch every last spoonful of sauce.
Get those three things right, and you're in for a very good supper.
I also like a few pieces of Japanese pickle on the side. Their sharpness cuts through the richness beautifully, and they provide a little welcome crunch between mouthfuls. But the real pleasure is the combination of chicken, curry, and rice. Simple ingredients, handled with a little care.
Chef's Secret: Really Crispy Chicken Katsu
I have a great deal of affection for panko breadcrumbs. Ordinary breadcrumbs are perfectly respectable, but panko belongs to an entirely different department when it comes to crunch.
The flakes are larger, lighter, and wonderfully irregular. When they meet hot oil, they create a crust that is crisp without becoming heavy.
There are a few little details worth remembering. First, make sure the chicken is an even thickness. This allows it to cook through without the breadcrumbs becoming too dark.
Second, don't skip the flour. The flour helps the beaten egg cling to the chicken, and the egg holds the breadcrumbs in place.
Finally, resist the temptation to fiddle with the chicken while it cooks. Give the breadcrumbs time to develop their beautiful golden colour before turning the cutlets.
And please, don't pile the cooked chicken onto kitchen paper. A wire rack allows the air to circulate underneath, keeping the crust crisp rather than allowing it to steam itself into submission.
Why I Add Apple to Japanese Curry
The first time someone encounters apple in a Japanese curry recipe, they might reasonably wonder whether we've wandered into the pudding department.
We haven't.
A little grated apple is a lovely way to introduce gentle sweetness without adding a great deal of sugar. As the curry simmers, the apple softens into the sauce, leaving behind a subtle sweetness that balances the warm spices.
I prefer a sweet apple, finely grated. Half a small apple is plenty. We're making curry, after all, not apple sauce.
A Good Japanese Curry Roux Is Worth Keeping in the Cupboard
I'm all for making things from scratch when the effort makes a noticeable difference. But I'm equally fond of a good shortcut.
Japanese curry roux is one of those ingredients I consider genuinely useful. It contains a blend of spices, seasonings, fat, and flour, all designed to create that distinctive thick Japanese curry sauce. You simply break it into pieces, stir it into the hot cooking liquid, and allow everything to simmer until smooth.
I prefer a medium heat variety, although you can choose something milder or hotter according to your taste.
One thing worth remembering is that different brands contain different amounts of salt and thickening ingredients. Taste the sauce before adding extra seasoning, and follow the package guidance when adjusting the quantity of liquid.
Why I Use Chicken Stock Instead of Just Water
Japanese curry roux is usually designed to be mixed with water, and there's absolutely nothing wrong with that. But I like to replace some of the water with good chicken stock.
It gives the sauce a little more savoury depth and works particularly well with the onions, carrots, and potatoes.
Choose a low sodium stock, though. The curry roux already brings plenty of seasoning to the party.
Common Mistakes to Avoid
Uneven chicken: thick spots stay raw while thin edges overcook, so pound it evenly.
Oil that is too cool: the panko soaks up oil and turns greasy instead of crisp.
Crowding the pan: fry in batches so the oil stays hot.
Draining on paper towels: the crust steams and softens, so use a wire rack.
Pouring curry over the chicken: serve it alongside so the crust stays crisp.
Salting too early: the roux is already well seasoned, so taste first.
Twists to Try
Pork tonkatsu curry: use thin boneless pork loin chops in place of the chicken.
Chicken thighs: boneless thighs, pounded flat, are juicier and very forgiving.
A little more heat: choose a hot curry roux, or add a pinch of cayenne to the sauce.
Extra vegetables: stir a handful of frozen peas into the curry for the last few minutes.
The Best Way to Serve Chicken Katsu Curry
I like a generous spoonful of freshly steamed Japanese short grain rice on one side of the plate. The sliced chicken sits alongside, with the curry sauce spooned next to it.
This way, you can enjoy the crisp chicken exactly as it should be, dipping each piece into the sauce as you eat.
Of course, some people prefer their chicken completely covered in curry. That's entirely their business. Personally, I think the breadcrumbs deserve a fighting chance.
And if you're feeling generous, put a little extra curry sauce on the table. It rarely goes to waste.

Frequently Asked Questions
What is chicken katsu curry?
Chicken katsu curry is a popular Japanese dish featuring breaded, fried chicken cutlets served with Japanese curry sauce and steamed rice. The chicken has a crisp panko coating, while the curry is typically thick, mildly spiced, and slightly sweet.
What is the difference between chicken katsu and chicken katsu curry?
Chicken katsu refers to the breaded and fried chicken cutlet itself. Chicken katsu curry combines that crispy chicken with Japanese curry sauce, usually served alongside rice.
What makes Japanese curry different from Indian curry?
Japanese curry is generally thicker, milder, and sweeter than many Indian curries. It is often prepared using packaged curry roux, which contains spices, seasonings, and thickening ingredients.
Can I make chicken katsu curry without Japanese curry roux?
Yes. You can make a Japanese style curry sauce from butter, flour, curry powder, stock, and seasonings. However, a good Japanese curry roux is convenient and delivers the familiar flavour and texture associated with this dish.
How do I keep chicken katsu crispy?
Use panko breadcrumbs, maintain an oil temperature of approximately 340°F (170°C), and avoid overcrowding the frying pan. Drain the cooked chicken on a wire rack rather than paper towels, and serve the curry sauce alongside the chicken.
Can I prepare chicken katsu curry in advance?
Yes. The curry sauce can be prepared up to three days ahead and refrigerated. For the best texture, fry the breaded chicken shortly before serving.
The Story Behind This Curry
Japanese curry is quite different from the fiery, fragrant curries of India or the aromatic coconut curries of Thailand. It has a character all its own. Rich, gently spiced, slightly sweet, and wonderfully comforting, with a sauce thick enough to cling to a spoon.
And there's something rather clever about the way it comes together.
A few onions, potatoes, carrots, ginger, and garlic form the foundation. A little grated apple brings sweetness, while a good Japanese curry roux does much of the heavy lifting.
I'm rather fond of ingredients that make life easier without compromising the pleasure of eating.
The chicken requires a little more attention, although nothing particularly demanding. Flour, beaten egg, and panko breadcrumbs, followed by a few minutes in a shallow pan of hot oil.
What emerges is a beautiful piece of chicken wearing a golden coat of breadcrumbs so crisp that cutting into it becomes one of the small pleasures of the evening.
And the smell!
Warm curry spices drifting from the saucepan, onions turning sweet, ginger and garlic releasing their fragrance, and that unmistakable aroma of breadcrumbs browning in hot oil.
By the time everything reaches the table, patience is in rather short supply.
I like to serve the chicken sliced into generous strips, with a mound of steamed Japanese rice and plenty of curry sauce alongside.
Not poured over the chicken, mind you.
We've gone to the trouble of making that crust beautifully crisp. It seems rather unkind to drown it before anyone has taken a bite.
One Last Thing
If you're making chicken katsu curry for the first time, don't be intimidated by the separate components.
The curry is quietly bubbling away while you prepare the chicken, and the rice needs very little attention once it's cooking.
Before long, you'll have a plate of golden chicken, warm rice, and thick, fragrant curry in front of you.
I usually start with a piece of chicken dipped into the sauce, followed by a little rice.
Then another piece of chicken.
Then perhaps a little more sauce.
And before I know it, I'm wondering whether anyone would notice if I helped myself to the last cutlet.
They probably would.
But I might risk it anyway.
