Ingredients

For the chicken katsu

• 2 boneless, skinless chicken breasts
• ½ teaspoon salt
• ½ teaspoon black pepper
• ½ cup all-purpose flour
• 2 large eggs, beaten
• 1½ cups panko breadcrumbs
• Vegetable oil, for frying

For the sandwich assembly

• 8 slices soft white bread (Japanese milk bread or brioche preferred)
• 4 tablespoons mayonnaise
• 2 tablespoons tonkatsu sauce or thick soy-based sauce
• 1 cup finely shredded cabbage (optional for crunch)
• Optional: sliced pickles, sliced cheese, spicy mustard

Step-by-Step Instructions

1. Prepare the Chicken

• Slice each chicken breast in half horizontally to create 4 thin cutlets
• Pound each cutlet lightly between plastic wrap to even thickness (about ½ inch)
• Season both sides with salt and pepper

2. Dredge and Bread

• Prepare three shallow bowls: one with flour, one with beaten eggs, and one with panko breadcrumbs
• Dredge each cutlet first in flour, then dip into egg, and finally coat thoroughly with panko
• Press breadcrumbs in gently to ensure a full coating

3. Fry the Chicken Katsu

• Heat ½ inch of vegetable oil in a skillet over medium heat
• Once hot (around 350°F / 175°C), carefully add the cutlets
• Fry 3–4 minutes per side until golden brown and cooked through
• Transfer to a paper towel-lined plate to drain excess oil

4. Prepare the Bread

• Trim crusts off bread slices if desired for traditional presentation
• Lightly toast or warm the bread if preferred, or keep soft for authentic texture

5. Assemble the Sandwich

• Spread mayonnaise on one slice of bread and tonkatsu sauce on the other
• Layer shredded cabbage over the mayonnaise side (optional)
• Place a crispy chicken cutlet on top of the cabbage
• Add any additional toppings like pickles or cheese
• Close the sandwich with the second slice of bread and press gently

6. Slice and Serve

• Slice the sandwich in half or into thirds for neat presentation
• Serve immediately with chips, fries, or a side salad

Ingredient Background

Chicken katsu is a Japanese adaptation of European-style breaded cutlets, typically made using pork (tonkatsu) or chicken (chicken katsu). The use of panko breadcrumbs sets it apart by creating an ultra-crisp, airy coating that retains less oil than traditional crumbs. Tonkatsu sauce, a thick, savory-sweet condiment made from fruits, vegetables, and spices, enhances the sandwich with a burst of umami. Soft white bread such as Japanese shokupan or brioche complements the crispy texture and allows the flavors to shine. Shredded cabbage is a classic addition in Japanese cuisine, offering crunch and freshness to balance the richness.

Technique Tips

• Use thin, even cutlets to ensure quick, uniform cooking
• Press breadcrumbs firmly onto chicken to avoid patchy coating
• Do not overcrowd the pan when frying to maintain oil temperature
• Let fried chicken rest briefly on paper towels to prevent sogginess
• Toast bread lightly if you want a firmer bite, but soft bread is traditional
• Use a serrated knife for cleaner cuts without squishing the sandwich

Alternative Presentation Ideas

• Cut sandwiches into finger-sized rectangles for party platters
• Serve open-faced with the cutlet on one slice and garnishes on top
• Wrap in parchment and twine for a rustic picnic look
• Stack mini versions on skewers for appetizer trays
• Arrange on a wooden board with dipping sauces and pickles

Additional Tips for Success

• Keep all breading stations organized to prevent mess and ensure consistency
• Chill breaded cutlets for 10 minutes before frying to help coating stick
• Double the katsu recipe and freeze extra cutlets for future use
• Customize sauce by mixing mayo with sriracha, wasabi, or honey mustard
• Use a meat thermometer to ensure internal temperature reaches 165°F (74°C)
• Let cutlets rest before assembling to keep the bread from absorbing excess steam

Recipe Variations

• Spicy chicken katsu: Add chili flakes or cayenne to the flour or serve with spicy mayo
• Teriyaki katsu sandwich: Glaze the chicken with teriyaki sauce before assembling
• Chicken katsu club: Add lettuce, tomato, and turkey bacon for a fusion twist
• Cheese katsu sandwich: Melt a slice of cheese over the hot cutlet before sandwiching
• Katsu sliders: Use small dinner rolls and mini cutlets for party-size sandwiches
• Vegetarian version: Substitute chicken with breaded tofu or eggplant slices

Freezing and Storage

• Store leftover chicken cutlets in an airtight container in the fridge for up to 3 days
• Reheat in an oven or air fryer to restore crispiness
• Breaded but uncooked cutlets can be frozen for up to 2 months
• Freeze between parchment sheets and fry directly from frozen
• Assembled sandwiches are best eaten fresh but can be wrapped and stored in the fridge for 1 day
• Avoid microwaving to preserve the crisp crust

Healthier Twist Ideas

• Bake or air fry the chicken instead of deep frying to reduce fat
• Use whole wheat or multigrain bread for added fiber
• Swap mayonnaise for Greek yogurt or light mayo
• Add more shredded vegetables like carrots or cabbage slaw
• Use olive oil spray instead of deep oil for cooking
• Reduce the sauce amount or make a lower-sugar version with homemade ingredients

Serving Suggestions for Events

• Bento boxes: Pack alongside rice balls, pickled vegetables, and fruit
• Lunch buffets: Offer cut sandwiches with dipping sauces on trays
• Picnic baskets: Wrap sandwiches in parchment for easy transport
• Kids’ lunches: Slice into smaller portions for child-friendly serving
• Game day snacks: Make sliders or wraps with chicken katsu strips
• Gourmet sandwich boards: Pair with other international sandwiches for a diverse spread

Special Equipment

• Large skillet or deep frying pan
• Tongs or slotted spoon
• Mixing bowls
• Meat mallet or rolling pin (for pounding cutlets)
• Serrated knife for slicing
• Wire rack or paper towels for draining
• Thermometer (optional for oil and internal temperature)
