Chicken Katsu Sando (Japanese Cutlet Sandwich)

Ultra-crispy chicken cutlet tucked into soft bread with a tangy-sweet katsu sauce and crunchy cabbage—classic Japanese lunch comfort, made at home.

Ingredients

• 2 chicken breasts (about 300–350g total), halved horizontally to make 4 thin cutlets
• 1/2 tsp salt
• 1/4 tsp black pepper
• 1/2 cup all-purpose flour
• 1 large egg
• 1 tbsp water
• 1 1/2 cups panko breadcrumbs
• Neutral oil, for shallow-frying (about 1–1.5 cm / 1/2 inch depth)
• 4 slices soft white sandwich bread (shokupan-style if possible)
• 2 cups finely shredded cabbage
• 3 tbsp ketchup
• 1 1/2 tbsp Worcestershire sauce
• 1 tsp soy sauce
• 1 tsp sugar

Method

• 1

  Step 1: Prep the cabbage & sauce

  Shred cabbage as finely as you can (a knife works; slice then cross-cut). Mix sauce ingredients in a small bowl until smooth. Taste: it should be tangy-sweet; adjust with a pinch more sugar if needed.

  Step 2: Butterfly & season chicken

  Halve chicken breasts horizontally to make thin cutlets (even thickness = even cooking). Season both sides with salt and pepper.

  Step 3: Crumb the cutlets (flour → egg → panko)

  Set up three bowls: flour, beaten egg + water, panko. Coat chicken in flour (tap off excess), dip in egg, then press firmly into panko so it really adheres—this is what gives that thick, shattery crust.

  Step 4: Shallow-fry until deeply golden

  Heat oil in a pan over medium-high to **170–175°C** (breadcrumb should sizzle immediately). Fry 2 cutlets at a time, **2–3 minutes per side**, until deep golden and cooked through (centre should be **74°C** or juices run clear). Transfer to a rack or paper towel; sprinkle a tiny pinch of salt while hot.

  Step 5: Rest, slice, and build the sando

  Rest chicken **2 minutes** (keeps it juicy), then slice into strips. Lay bread down, pile on cabbage, drizzle generously with katsu sauce, add chicken, spoon a little more sauce over, then top with bread. Press gently, cut in half, and eat right away while the crust is crisp.

Tips

• **Crispier katsu:** Press panko on firmly and keep oil temperature steady—if it’s too cool, the crust turns oily instead of crisp.
• **Neater sandwiches:** Wrap the assembled sando tightly in parchment or plastic wrap for 2 minutes, then slice—clean edges, less slippage.
• **Make-ahead:** Sauce and shredded cabbage can be prepped up to **24 hours** ahead and refrigerated (keep cabbage covered so it stays crisp).
• **Serve with:** A light miso-style soup or simple cucumber salad (salt + a splash of soy) for an easy, balanced lunch.
