How do I keep the chicken katsu crispy after frying?

Drain on paper towels immediately after frying and assemble the sandwich within 10–15 minutes. Avoid wrapping tightly in plastic while still warm, as steam will soften the crust.

Can I pound the chicken thinner for faster cooking?

Yes, pound chicken breasts to 1/4-inch thickness before breading. This reduces frying time and ensures even, crispier results.

What is tonkatsu sauce and can I substitute it?

Tonkatsu is a thick, sweet-savory Japanese sauce similar to Worcestershire mixed with ketchup. Use store-bought tonkatsu or mix equal parts ketchup and Worcestershire with a touch of soy sauce and sugar.

How do I make the cabbage slaw creamy?

Toss shredded cabbage and green onions with a light dressing of mayo, rice vinegar, sugar, and salt. Let it sit 10 minutes before serving to soften the cabbage.

What temperature oil do I need for frying?

Heat oil to 350–375°F. At this temperature, the panko will turn golden in 3–4 minutes per side without burning.

Instructions

1
Prepare the three-part breading station. In a shallow dish, mix together flour, salt, and pepper.
2
In a second shallow dish, whisk the eggs with milk, salt, and pepper.
3
In a third shallow dish, combine the panko breadcrumbs with salt, pepper, and garlic powder.
4
To make the slaw, thinly shred the cabbage. In a mixing bowl, combine the shredded cabbage, chopped green onions, Japanese mayonnaise, lemon juice, and a sprinkle of salt. Toss to combine and set aside.
5
To make the tonkatsu sauce, whisk together ketchup, oyster sauce, Worcestershire sauce, and brown sugar in a small bowl until smooth.
6
Prepare the chicken. Place chicken breasts between two sheets of plastic wrap and pound to an even thickness, about 1/2 inch.
7
Dredge each piece of chicken first in the flour mixture, then dip in the egg wash, and finally coat thoroughly in the panko breadcrumbs, pressing gently to adhere.
8
Heat about an inch of vegetable oil in a large pan over medium-high heat. Carefully place the breaded chicken in the hot oil and fry for 3-5 minutes per side, until golden brown, crispy, and cooked through.
9
Remove the chicken from the pan and let it rest on a wire rack.
10
Assemble the sandwiches. Spread Japanese mayonnaise on three slices of bread and tonkatsu sauce on the other three slices.
11
Top the mayonnaise-spread slices with a generous amount of slaw, followed by a piece of fried chicken katsu.
12
Place the tonkatsu sauce-spread slices on top to complete the sandwiches. For easier handling, you can wrap each sandwich tightly in parchment paper.
13
Using a sharp serrated knife, cut the sandwiches in half. Garnish with additional chopped green onions if desired, and serve immediately.
