Directions

  1. Season and temper the chicken

    Pat the cutlets dry and season both sides with the salt and pepper. Leave them at room temperature for 10 minutes while you make the sauce; the even 1/2-inch thickness keeps the breading from overbrowning before the centers cook.

  2. Simmer the tonkatsu sauce

    Whisk the ketchup, Worcestershire, soy sauce, honey, rice vinegar, ginger, sesame oil, and water in a small saucepan. Bring to a gentle simmer over medium-low heat and cook for 3 to 4 minutes, stirring, until glossy and thick enough to coat a spoon. Remove from the heat.

  3. Bread the cutlets

    Set three shallow dishes in a row. Put the remaining 1/2 cup flour in the first. Beat the eggs with 1 tablespoon water in the second. Put the panko in the third. Coat each cutlet in flour, shake off the excess, dip in egg, then press firmly into panko so the surface is completely covered.

  4. Shallow-fry to safe doneness

    Heat the neutral oil in a large heavy skillet over medium-high heat to 350°F; it should be about 1/4 inch deep. Fry two cutlets at a time for 3 to 4 minutes per side, adjusting the heat to keep the oil between 335°F and 355°F. Transfer to a rack when deeply golden and the thickest part reaches 165°F. Repeat with the remaining cutlets.

  5. Rest, slice, and sauce

    Rest the chicken on the rack for 5 minutes, then slice crosswise into 3/4-inch strips. Spoon a shallow pool of warm tonkatsu sauce onto each plate, set the sliced chicken over it so the top stays crisp, and finish with scallions and sesame seeds.

Why this works

Why it worksAn even, thin cutlet reaches 165°F before its panko shell becomes too dark.
Why it worksA brief simmer melds the tangy, sweet, savory sauce while fresh ginger and rice vinegar keep it from tasting flat.
Why it worksPlacing only the underside of the katsu in the sauce preserves the contrast between crisp crust and glossy sauce.

Swaps & notes

Easy swaps

  • Use boneless pork loin cutlets of the same thickness and cook them to 145°F, followed by a 3-minute rest.
  • For a vegetarian version, bread four 1-inch slabs of pressed extra-firm tofu and fry until crisp and hot throughout.
  • For gluten-free katsu, use a cup-for-cup gluten-free flour blend, gluten-free panko, tamari, and Worcestershire sauce labeled gluten-free.

Cook notes

  • Use a rack rather than paper towels for the fried cutlets; airflow prevents steam from softening the underside.
  • A clip-on or instant-read thermometer helps keep the frying oil near 350°F. Oil that is too cool makes greasy breading; oil that is too hot browns before the chicken is safe.
  • The calorie and cost estimates assume roughly one-third of the frying oil remains in the finished food and exclude optional rice or cabbage.

Storage

Refrigerate the sauce and katsu in separate airtight containers for up to 3 days. Reheat the sauce gently in a saucepan and re-crisp the chicken on a rack in a 375°F oven or air fryer for 7 to 10 minutes until it reaches 165°F; microwaving softens the crust. Freeze fully cooled cooked katsu for up to 2 months, but make the sauce fresh for the brightest flavor.

Questions

Can I bake the chicken katsu instead of frying it?

Yes. Toast the panko with 2 tablespoons oil in a skillet until golden, bread the chicken with it, mist both sides with oil, and bake on a rack at 425°F for 14 to 18 minutes until the center reaches 165°F.

Can I use bottled tonkatsu sauce?

Yes. Use about 3/4 cup and warm it gently with 1 teaspoon rice vinegar and 1 teaspoon grated ginger to restore some of the brightness of the homemade version.

Can I prepare any part ahead?

Make the sauce up to 5 days ahead. Bread the cutlets no more than 4 hours ahead, refrigerate them uncovered on a rack, and fry just before serving.
