Crispy Chicken Katsu Curry with From-Scratch Sauce
Make the ultimate chicken katsu curry at home with shatteringly crisp panko-crusted cutlets and a rich, velvety curry sauce made from scratch with onion and apple.
There is no comfort food quite like a golden chicken katsu curry. While many shortcut recipes rely on store-bought roux blocks, making your own sauce from scratch allows you to control the balance of sweetness and spice, creating a much deeper, more complex flavor profile that perfectly complements a fried cutlet.
This easy katsu curry method focuses on two essential textures: the 'shatter-crunch' of the panko coating and the silky, glossy finish of the curry gravy. By incorporating a grated apple and a touch of soy sauce into the roux, we achieve that signature Japanese profile—savory, slightly sweet, and incredibly aromatic.
Whether you are a seasoned pro or looking for a reliable japanese chicken katsu curry recipe for a weeknight dinner, the secret lies in the shallow fry. We use just enough oil to crisp the chicken without making it greasy, ensuring every bite stands up to the generous blanket of warm curry sauce.
Ingredients
The Curry Sauce
- 2 tablespoons (28g) unsalted butter
- 2 tablespoons (16g) all-purpose flour
- 1 tablespoon neutral oil
- 1 large yellow onion, finely minced
- 2 cloves garlic, grated
- 1 inch fresh ginger, grated
- 1 small Fuji or Gala apple, peeled and finely grated
- 2 tablespoons Japanese curry powder (S&B brand recommended)
- 2 cups (475ml) chicken stock, low sodium
- 1 tablespoon soy sauce
- 1 tablespoon ketchup
- 1 teaspoon honey or brown sugar
The Chicken Katsu
- 2 large boneless skinless chicken breasts (approx. 1 lb / 450g)
- 1/2 cup (60g) all-purpose flour
- 1 large egg, beaten with 1 teaspoon water
- 1.5 cups (90g) Panko breadcrumbs
- Kosher salt and black pepper to taste
- Neutral oil for shallow frying (canola or grapeseed)
To Serve
- Steamed short-grain Japanese rice
- Fukujinzuke (red pickled radish) or pickled ginger
- Finely shredded green cabbage
Instructions
- 1
Sauté the aromatics by heating 1 tablespoon of oil in a saucepan over medium heat; add the minced onion and cook for 8-10 minutes until soft and starting to caramelize.
- 2
Stir in the grated garlic, ginger, and apple, cooking for another 2 minutes until fragrant and the moisture has mostly evaporated.
- 3
Make the roux by adding the butter to the pan; once melted, whisk in the flour and curry powder, stirring constantly for 2 minutes to toast the spices without burning them.
- 4
Simmer the sauce by slowly whisking in the chicken stock to avoid lumps, then add the soy sauce, ketchup, and honey; simmer on low for 15 minutes until thickened, then keep warm.
- 5
Prepare the chicken by slicing the breasts in half horizontally to create four thin cutlets, then pound them to an even 1/2-inch thickness with a meat mallet.
- 6
Dredge the cutlets by seasoning them with salt and pepper, then coating each in flour, dipping in the beaten egg, and finally pressing firmly into the panko crumbs until fully insulated.
- 7
Shallow fry the chicken in a large skillet with about 1/2 inch of oil heated to 350°F (175°C); cook for 3-4 minutes per side until deeply golden and the internal temperature reaches 165°F.
- 8
Rest the chicken on a wire rack for 2 minutes to keep the bottom from getting soggy, then slice into thick strips.
- 9
Assemble the plates by placing a mound of rice on one side, leaning the sliced katsu against it, and ladling the warm curry sauce over half of the chicken and rice.

Tips
- → Don't skip the grated apple; it provides the essential 'hidden' sweetness and acidity that defines authentic Japanese curry.
- → Use a wire cooling rack instead of paper towels for the fried chicken to ensure air circulates around the panko, keeping it shatteringly crisp.
- → If you prefer a perfectly smooth sauce, you can run the finished curry gravy through a fine-mesh sieve or use an immersion blender before serving.
FAQ
Can I make the katsu curry sauce ahead of time?
Yes, the sauce actually tastes better the next day. Store it in an airtight container for up to 3 days and reheat gently on the stove, adding a splash of water or stock if it has thickened too much.
How do I keep the panko from falling off the chicken?
Ensure the chicken is patted dry before the flour dredge, and make sure you press the panko firmly into the egg-washed chicken with the palm of your hand.
Why does my katsu curry sauce taste bitter?
This usually happens if the curry powder or the flour roux is scorched. Always toast spices over medium-low heat and stir constantly.
