Chicken Katsu

If using skin-on thighs, leave the skin on — it fries up into a crackling layer that contrasts beautifully with the panko crust. Open the thigh flat and trim any large pockets of fat from the interior that would not render during shallow frying. Place between two sheets of plastic wrap and pound gently with the flat face of a meat mallet from the center outward until the thigh is an even 1.5 cm thickness throughout — thick patches will not cook through by the time the crust reaches full color. Season both sides with fine salt and white pepper immediately before dredging.

Combine the Worcestershire sauce, ketchup, and oyster sauce in a small bowl. Stir well to combine. Taste — the sauce should be sweet, tangy, and deeply savory with a slight fermented undertone. Adjust ratios to personal taste: more Worcestershire for depth and tang, more ketchup for sweetness and body, a touch more oyster sauce for umami. This is a quick approximation of commercial Bull-Dog sauce. Allow to sit for 5 minutes for the flavors to integrate.

Set up three shallow dishes: flour, beaten egg, and panko. Dredge each thigh in flour, patting off every trace of excess. Dip into beaten egg, letting the excess drip for 2 seconds. Press firmly into the panko, then flip and press again — unlike schnitzel, katsu benefits from a thick, pressed panko coating that builds a robust, shattering crust rather than a delicate one. The coating should be visibly thick. Heat oil to 170°C / 340°F in a heavy pan — enough oil to come halfway up the thigh. Fry skin-side down (or top-side down) for 4 minutes until deep golden. Flip carefully and fry 3 minutes on the second side until deep golden and the thickest part reads 74°C / 165°F. Drain on a rack.

Rest the fried katsu on the rack for 2 minutes — this allows the crust to set and the interior to equilibrate. Using a sharp, heavy knife with one clean downward press per cut (not a sawing motion, which tears the crust), slice into 2–3 cm strips across the width, keeping the slices in the original shape of the thigh. Reassemble the sliced pieces on the cutting board and slide as a unit onto warmed plates beside a mound of shredded cabbage. Drizzle tonkatsu sauce across the slices or serve alongside for dipping.
