How to Make Japanese Chicken Katsu with Tonkatsu Sauce

Flatten Chicken: Place each chicken breast between two sheets of plastic wrap and gently pound with a meat mallet until 1/2-inch thick.
Season and Dredge: Season the all-purpose flour with salt and pepper, then dredge each chicken breast evenly, shaking off any excess for a light, even coating that crisps up beautifully golden.
Dip in Egg: Beat eggs in a shallow bowl until smooth, then dip each floured chicken breast fully, ensuring the entire surface is coated to bind the panko breadcrumbs tightly.
Coat with Panko: Press each egg-coated chicken breast firmly into the panko breadcrumbs, patting gently to form an even, compact crust that delivers the signature crispy texture on every bite.
Heat Oil: Warm 1/2-inch vegetable oil in a large skillet over medium-high heat (around 350°F) until shimmering and hot, about 3 minutes, to ensure an ideal frying temperature.
Fry Chicken: Carefully add each breaded breast to the hot oil, frying 3–4 minutes per side until deeply golden brown, then transfer to a paper towel-lined plate to drain excess oil.

For the Tonkatsu Sauce:

Prepare Sauce: Whisk ketchup, Worcestershire sauce, soy sauce, sugar, rice vinegar, and mustard in a small bowl until smooth and glossy, creating a balanced, tangy-sweet Tonkatsu sauce.
Slice and Serve: Allow the fried chicken to rest 2 minutes, then slice each breast into strips. Arrange on plates and serve immediately with the warm Tonkatsu sauce for dipping.

Optional: garnish with shredded cabbage and lemon wedges.

Expert Tips for Japanese Chicken Katsu with Tonkatsu Sauce

Pound Evenly: Make sure to pound the chicken breasts to an even 1/2-inch thickness for uniform cooking and a tender bite every time.
Keep Oil Hot: Maintain the oil temperature around 350°F to achieve that perfect crispy crust without absorbing excess oil.
Press Panko Firmly: Gently press the panko breadcrumbs onto the egg-coated chicken so they stick well and create that iconic crunchy texture.
Rest Before Slicing: Let the fried chicken rest a couple of minutes to keep juices locked in and the coating crispy when sliced.
Balance Sauce Flavors: Whisk the Tonkatsu sauce ingredients thoroughly to blend tangy, sweet, and savory notes for a harmonious dipping experience.
Avoid Overcrowding: Fry the chicken in batches if needed; overcrowding the pan lowers the oil temperature and compromises crispiness.
