# Crispy Chicken Katsu

Chicken katsu is a Japanese chicken cutlet coated in panko breadcrumbs and fried until shatteringly crisp. It is served sliced over rice with shredded cabbage and a sweet, tangy katsu sauce.

The chicken is pounded thin so it cooks in minutes, and shallow frying keeps the cleanup simple. The sauce takes one minute and uses pantry ingredients.

## Ingredients

- 4 boneless, skinless chicken breasts (about 700 g total)
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1/2 cup all-purpose flour
- 2 eggs, beaten
- 2 cups panko breadcrumbs
- 1 cup neutral oil, for shallow frying
- 3 tbsp ketchup
- 2 tbsp Worcestershire sauce
- 1 tbsp soy sauce
- 1 tsp sugar
- 1 tsp Dijon mustard
- 1/4 head cabbage, finely shredded

## Method

1. Slice each breast in half horizontally to make 8 cutlets, then pound to an even 1 cm (1/2 inch). Season both sides with the salt and pepper.
2. Mix the ketchup, Worcestershire, soy sauce, sugar and mustard in a small bowl for the katsu sauce.
3. Set up three dishes: flour, beaten egg, and panko. Dredge each cutlet in flour, dip in egg, then press firmly into panko.
4. Heat the oil in a large skillet over medium-high heat to 350°F (175°C), or until a panko crumb sizzles right away.
5. Fry 3 to 4 cutlets at a time, 2 to 3 minutes per side, until deep golden and 165°F (74°C) inside.
6. Drain on a wire rack so the bottom stays crisp.
7. Slice the cutlets into strips and serve over rice with shredded cabbage and the katsu sauce.

## Why it works

- Pounding the breast to an even thickness lets it cook quickly while the crust browns.
- Flour, egg and panko build three layers that stick together and fry up crunchy.
- Panko is airy and coarse, so it stays crisp longer than fine breadcrumbs.
- Frying at 350°F (175°C) crisps the crust quickly without soaking up oil.
- Draining on a rack keeps the bottom from steaming and turning soggy.

## The science

- **Three-step breading.** Flour dries the surface so egg can cling, and the egg acts as glue for the panko. Skipping a step weakens the bond and the crust slides off. Press the crumbs firmly so they fuse to the chicken during frying.
- **Oil temperature.** If oil is too cool, the crust soaks it up and turns greasy. If too hot, the outside burns before the chicken is cooked. Around 350°F (175°C) quickly dries and browns the crumbs while the thin cutlet finishes cooking.
- **Texture contrast.** Crunchy crust, juicy meat and crisp raw cabbage keep each bite interesting. The cool, fresh cabbage and tangy sauce also cut the richness of the fried chicken, making the whole plate feel balanced and keeping you reaching for another bite.

## Tips

- Use one hand for the dry dishes and one for the egg to avoid clumpy fingers.
- Fry in batches so the oil stays hot.
- Cut the cutlets just before serving to keep the crust crisp.

## Mistakes to avoid

- Skipping the pounding leaves the thick part undercooked, so even the cutlets out.
- Frying in oil that is too cool makes greasy crust, so check the temperature.
- Putting cutlets on a plate to drain steams the bottom, so use a wire rack.

## Variations and swaps

- Bake at 425°F (220°C) on an oiled rack for 18 to 20 minutes, flipping once.
- Serve with Japanese curry sauce for katsu curry.
- Use pork cutlets for tonkatsu and fry 3 to 4 minutes per side to 145°F (63°C).
- Swap chicken breast for boneless thighs and fry 4 to 5 minutes per side.
- Swap panko for crushed cornflakes if you do not have it.
- Swap store-bought tonkatsu sauce for the homemade sauce to save time.

## Storage

Refrigerate within 2 hours and eat within 3 to 4 days. Reheat in a 400°F (200°C) oven or air fryer for 8 to 10 minutes until crisp and 165°F (74°C).

## FAQ

**What is the difference between chicken katsu and fried chicken?**

Katsu is a thin cutlet coated in panko and shallow fried, giving a light, very crisp crust. Fried chicken is usually bone-in and coated in seasoned flour.

**Can you bake chicken katsu?**

Yes. Bake at 425°F (220°C) on an oiled rack for 18 to 20 minutes, flipping once. Toasting the panko in a little oil first helps browning.

**What is katsu sauce made of?**

Ketchup, Worcestershire sauce, soy sauce, sugar and a little mustard. It is sweet, tangy and savory.

**What do you serve with chicken katsu?**

Steamed rice and shredded cabbage are traditional. Japanese curry, miso soup and pickles also work well.

**How do you keep katsu crispy?**

Fry at 350°F (175°C), drain on a rack and slice just before serving. Do not stack the hot cutlets on top of each other.
