Ingredients
For the sauce:

- 2 tablespoons soy sauce
- 2 teaspoons brown sugar
- 1 tablespoon mirin
- 2 teaspoons Worcestershire sauce
- 1 teaspoon freshly grated ginger
- 1 teaspoon finely minced garlic
For the chicken katsu:
- 1 pound boneless skinless chicken breast cut in half horizontally
- salt
- 1 1/2 cups all-purpose flour
- 3 eggs
- 1 1/2 tablespoons water
- 3 cups panko breadcrumbs
- vegetable oil for cooking
Equipment
- Cutting board and chef’s knife
- Three shallow bowls or pie plates for dredging stations
- Large skillet or frying pan
- Instant-read thermometer (optional)
- Paper towels and a wire rack for draining
- Saucepan and whisk
Prep and tips

- Pat the chicken dry before seasoning — this helps the coating stick and fry up crisp.
- Cutting the chicken breast in half horizontally makes thinner cutlets that cook quickly and evenly.
- Keep the panko close by; you want to press it gently onto the egg-wet surface so it adheres well.
- Use a neutral vegetable oil with a high smoke point and maintain medium-high heat so the katsu browns without absorbing too much oil.
Step-by-step directions

- Make the tonkatsu sauce: Combine 1/2 cup ketchup, 2 tablespoons soy sauce, 2 teaspoons brown sugar, 1 tablespoon mirin, 2 teaspoons Worcestershire sauce, 1 teaspoon freshly grated ginger, and 1 teaspoon finely minced garlic in a small saucepan. Whisk until smooth. Place over low heat and warm gently for 2 to 3 minutes to meld the flavors, stirring occasionally. Remove from heat and set aside to cool slightly while you prepare the chicken.
- Prepare the chicken: Place the 1 pound boneless skinless chicken breast cut in half horizontally on a cutting board. If pieces are uneven, use the flat of your hand or a meat mallet to gently pound each piece to an even thickness so they cook uniformly. Lightly season both sides with salt.
- Set up dredging stations: In three shallow bowls or pie plates, arrange the dredging stations in this order: 1 1/2 cups all-purpose flour in the first bowl; in the second bowl, whisk 3 eggs with 1 1/2 tablespoons water until smooth; in the third bowl, pour 3 cups panko breadcrumbs. Make sure each piece of chicken has easy access to each station.
- Coat the chicken: Working with one piece at a time, press the chicken into the flour to fully coat, shaking off any excess. Dip the floured chicken into the egg mixture, letting excess drip off, then press it firmly into the panko breadcrumbs so the surface is thoroughly coated. Set the breaded cutlet on a plate and repeat with remaining pieces.
- Heat the oil: Pour enough vegetable oil into a large skillet to create a shallow layer about 1/4 to 1/3 inch deep. Heat the oil over medium-high heat until it shimmers and a breadcrumb dropped into the oil sizzles immediately. If you have an instant-read thermometer, aim for an oil temperature of roughly 350°F (175°C). Adjust heat as needed to maintain temperature.
- Fry the cutlets: Carefully place the breaded chicken cutlets in the hot oil without crowding the pan; work in batches if necessary. Fry for about 2 to 3 minutes per side, or until the crust is deep golden brown and the internal temperature reaches 165°F (74°C). Use tongs to flip gently so the coating stays intact.
- Drain and rest: Transfer the cooked cutlets to a wire rack set over a baking sheet or paper towels to drain excess oil. Let them rest for a minute or two; this helps the crust stay crisp and allows the juices to settle.
- Slice and serve: Use a sharp knife to slice each cutlet into strips. Serve the sliced cutlets with the warm homemade tonkatsu sauce on the side for dipping or drizzled lightly over the top. This dish pairs beautifully with steamed rice, shredded cabbage, and a wedge of lemon if you like a citrusy lift.
Serving suggestions
- Serve Crispy Japanese Chicken Katsu with Homemade Tonkatsu Sauce over a bed of steamed rice and a pile of thinly shredded cabbage for a classic presentation.
- Add a small bowl of pickled ginger or Japanese-style pickles to cut through the richness.
- Turn leftovers into a katsu sandwich by layering sliced cutlet and cabbage between soft bread and slathering with the sauce.
Make-ahead and storage
- Tonktasu sauce keeps well in an airtight container in the refrigerator for up to 5 days. Rewarm gently before serving.
- For the crispiest results, reheat the chicken katsu in a 350°F (175°C) oven on a wire rack for 8–10 minutes until warmed through and the crust re-crisps. Avoid the microwave if you want to preserve texture.
Quick troubleshooting
- If the crust absorbs too much oil, the pan temperature is likely too low. Increase the heat slightly so the coating browns quickly.
- If the panko falls off during frying, press the crumbs firmly onto the egg-wet surface and make sure excess egg is allowed to drip off before breading.
- If the chicken is browning too fast before the center cooks, reduce heat to medium and fry a little longer, or finish in a preheated 350°F (175°C) oven.

Crispy Japanese Chicken Katsu with Homemade Tonkatsu Sauce
Ingredients
Equipment
Method
- Make the tonkatsu sauce: In a small bowl combine ketchup, soy sauce, brown sugar, mirin, Worcestershire sauce, grated ginger, and minced garlic; stir until smooth. Set aside and let rest at least 30 minutes.
- Pound the chicken: Place each halved chicken breast between plastic wrap and gently pound with a meat mallet or rolling pin until about 1/4 inch thick.
- Season and rest: Salt both sides of the chicken liberally, cover, and refrigerate for about 1 hour to improve juiciness (optional but recommended).
- Prepare breading station: Put the flour in one shallow bowl, beat the eggs with 1 1/2 tablespoons water in a second bowl, and place the panko in a third bowl.
- Bread the chicken: Dredge each piece in flour and shake off excess, dip into the egg wash, then press into panko to coat evenly. Place coated pieces on a wire rack.
- Preheat the oven to 200°F and add enough vegetable oil to coat the bottom 1/2 inch of a large skillet; heat oil to about 350°F (medium-high).
- Pan-fry the chicken: Working without overcrowding, add chicken to the hot oil and cook 1–2 minutes per side just until the crust sets and turns golden, flipping as needed.
- Finish in the oven: Transfer fried chicken to a clean wire rack and keep in the preheated oven to finish cooking, about 7–8 minutes depending on thickness, until internal temperature reaches 165°F.
- Slice and serve: When cooked through, cut the chicken into thin strips and serve with rice and the prepared tonkatsu sauce.
Notes
- Letting the sauce rest melds the flavors.
- Pounding the chicken thin ensures even cooking.
- Refrigerating the salted chicken improves juiciness.
- Do not overcrowd the pan to maintain oil temperature.
