Extra Crispy Chicken Katsu with 4 Ingredient Tonkatsu Sauce

You may already know chicken katsu as Japan’s take on breaded fried chicken. This easy version is crisp, quick, and simple to make at home—no need to order takeout. From start to finish it takes about 45 minutes, and the result is golden, crunchy chicken served over steamed rice with a tangy four-ingredient sauce.

Erm… what’s chicken katsu?

Chicken katsu is essentially a Japanese-style schnitzel: thin chicken cutlets coated in panko breadcrumbs and fried until ultra-crispy. It’s commonly served sliced over white rice and finished with a sweet-savory sauce called tonkatsu sauce. The technique is straightforward and produces a satisfying contrast of crunchy exterior and juicy chicken inside.

What’s tonkatsu sauce?

Tonkatsu sauce is a thick, tangy-sweet condiment that complements breaded fried meats. This easy homemade version uses just four pantry ingredients: mustard, ketchup, Worcestershire sauce and soy sauce. It tastes a bit like a richer, slightly sweeter barbecue sauce. There’s no cooking required—just whisk the ingredients together and adjust to your taste.

Fan of crispy foods? You’ve come to the right place!

This recipe stands out for two reasons: it’s quick and it yields exceptional crispiness. The method is deliberately simple so you can get dinner on the table fast without sacrificing texture. A double coating in panko and shallow frying (or air frying) gives the chicken a crackly, golden crust.

I’m sold! How do you make it?

Below is a concise overview of the process, followed by a detailed ingredient list and step-by-step instructions.

Step 1: Make the tonkatsu sauce by whisking the mustard, ketchup, Worcestershire and soy sauce together. Prepare rice to steam or boil.

Step 2: Slice the chicken breasts thinly, season, then coat in beaten egg and panko breadcrumbs. For extra crunch, repeat the egg-and-panko coating a second time.

Step 3: Shallow fry the breaded chicken in a skillet until golden on both sides, or cook in an air fryer with a light spray of oil for a healthier finish.

Step 4: Drain on paper towel, slice into strips, and serve over rice with the tonkatsu sauce drizzled on top.

Tip: Slice each chicken breast in half horizontally with a sharp knife, then cut each piece in half crosswise. Smaller, thinner pieces cook quickly and stay juicy—about three minutes per side in a hot pan is usually sufficient. Avoid overcooking.

Can you cook the chicken in an air fryer?

Yes. Lightly spray the breaded chicken with oil and air fry for roughly five minutes per side at a medium-high temperature. The result is very crispy with less oil than traditional pan frying.

How do you eat katsu?

Serve chicken katsu simply and attractively:

1. Slice the cooked chicken into strips.
2. Lay the slices across a bed of steamed white rice.
3. Drizzle tonkatsu sauce over the chicken and rice.
4. Optional: serve with crisp lettuce leaves or a side of steamed or stir-fried vegetables.

Make it your own: Add a wedge of lemon, chopped spring onions, or a simple cabbage slaw to introduce freshness and balance the richness of the fried chicken.

Super crispy chicken katsu

By: Helen Schofield

A quick, reliable weeknight recipe: thinly sliced chicken breasts double-coated in panko for a satisfying crunch, served with a simple homemade tonkatsu sauce.

Prep: 12 mins

Cook: 30 mins

Total: 42 mins

Servings: 2

Equipment

• Air fryer (optional)
• Frying pan or skillet

Ingredients

For the chicken

• 2 chicken breasts, boneless and skinless
• Salt and pepper, to taste
• 1 egg, beaten
• 1½ cups panko breadcrumbs
• Olive or vegetable oil for shallow frying

For the tonkatsu sauce

• 1 teaspoon mustard (Dijon or ½ tsp dry mustard + 1 tsp water)
• ½ cup ketchup
• 2 tablespoons Worcestershire sauce
• 2 teaspoons soy sauce

To serve

• Cooked white rice
• Crisp salad leaves
• Optional: steamed vegetables or stir-fried greens

Instructions

1. Make the sauce: whisk mustard, ketchup, Worcestershire sauce and soy sauce together. Set aside.
2. Prepare the chicken: slice each breast in half horizontally with a sharp knife, then cut each piece in half width-wise. Season both sides with salt and pepper.
3. Set up coating stations: spread panko on a plate and whisk the egg in a shallow dish.
4. Coat the chicken: dip each piece in the egg, press into panko until fully covered. Shake off excess, then repeat the egg and panko step a second time for extra crunch. Arrange the crumbed pieces on a plate.
5. Cook rice while the chicken cooks so everything is ready together.
6. Shallow fry: pour enough oil into a frying pan to barely cover the bottom and heat until hot. Test with a few breadcrumbs—if they sizzle energetically, the oil is ready. Fry a few pieces at a time for about 3 minutes per side, or until golden brown and cooked through. For an air fryer, spray lightly with oil and cook about 5 minutes per side.
7. Drain on paper towels, then slice each piece into 1-inch strips.
8. Serve immediately over rice. Drizzle tonkatsu sauce over the chicken and rice, and pass extra sauce on the side for dipping.

Notes

Double coating the chicken ensures a crisp exterior. Keep cutlets thin so they cook quickly and remain moist; overcooking dries the meat out. If you prefer convenience, store-bought tonkatsu or Worcestershire-style sauce works fine. Serve with fresh crunchy lettuce or a simple cabbage slaw for balance. A side of steamed broccoli or mixed stir-fried vegetables also pairs nicely.
