Step-by-Step Instructions
Step 1: Make the sweet-savory katsu-style sauce
In a small bowl, whisk together the ketchup, Worcestershire sauce, soy sauce, mirin, and brown sugar until smooth. Set aside at room temperature.
If you want it warmer for serving, microwave it in a microwave-safe bowl for 10–15 seconds, then stir again.
Step 2: Toss the cabbage slaw and let it lightly pickle
In a medium bowl, combine the shredded cabbage, rice vinegar, sugar, and salt. Toss well and let sit for 10 minutes while you prep the chicken. This quick rest softens the cabbage slightly and adds a bright, crunchy bite.
Step 3: Prep the chicken cutlets and set up a breading station
Place the chicken breasts on a cutting board. Butterfly each breast horizontally, then cut in half so you have 4 thin cutlets. If any pieces are thick, cover with plastic wrap and gently pound to an even thickness of about 1/2 inch (1.3 cm).
Set up three shallow bowls:
- Bowl 1: flour + 3/4 teaspoon kosher salt + black pepper + garlic powder; whisk to combine.
- Bowl 2: 2 eggs + 1 tablespoon water; beat until smooth.
- Bowl 3: panko breadcrumbs.
Working with one cutlet at a time, coat in seasoned flour (shake off excess), dip in egg wash (let excess drip), then press firmly into panko on both sides.
Step 4: Fry the chicken until deeply golden and cooked through
In a heavy skillet or Dutch oven, add 2 cups (480 ml) neutral oil (aim for about 3/4 inch / 2 cm depth). Heat over medium-high until the oil reaches 350°F (177°C).
Fry 1–2 cutlets at a time (don’t crowd the pan) for 3–4 minutes per side, adjusting heat as needed to keep the oil near 350°F (177°C). The crust should turn a rich golden brown.
Transfer to a wire rack set over a sheet pan (or a paper towel–lined plate). The chicken is done when the thickest part reaches 165°F (74°C) on an instant-read thermometer.
Let the cutlets rest for 5 minutes before assembling so the juices stay in the chicken.
Step 5: Make soft scrambled eggs (creamy, not dry)
In a bowl, whisk together the 8 eggs, milk, and salt until the whites and yolks are fully combined.
Heat a nonstick skillet over medium-low. Add the butter and let it melt without browning. Pour in the eggs and use a silicone spatula to stir slowly and continuously, scraping the bottom and sweeping the curds toward the center.
Cook for 3–5 minutes, lowering the heat if needed, until the eggs are softly set and still glossy. Remove from heat immediately (they will carry over and finish setting).
Step 6: Toast the buns for crunch and structure
Wipe out the egg pan if needed, or use a separate skillet or toaster. Toast buns cut-side down until lightly crisp and golden, about 2–3 minutes in a skillet over medium heat, or 2–4 minutes in a toaster.
Toasting helps the bun hold up to the sauce and juicy chicken.
Step 7: Assemble the sandwiches (keep the crunch!)
Build each sandwich in this order:
- Bottom bun
- About 1 tablespoon sauce (spread it to create a moisture barrier)
- 1 crispy chicken cutlet
- Another 1 tablespoon sauce (drizzle or spread)
- A small mound of cabbage slaw (drain any excess liquid first)
- A generous scoop of soft scrambled eggs (about 1/2 cup per sandwich)
- Optional scallions and/or sesame seeds
- Top bun
Serve immediately while the chicken is crisp and the eggs are warm.
Pro Tips
- Press the panko in: After coating, press the breadcrumbs firmly into the chicken so the crust doesn’t fall off during frying.
- Use a rack, not just paper towels: Draining on a wire rack keeps the crust crisp (paper towels can trap steam).
- Keep oil temperature steady: Aim for 350°F (177°C). Too cool = greasy; too hot = burnt coating before the chicken cooks.
- Don’t overcook the eggs: Pull them when they’re still glossy; they’ll finish setting off the heat.
- Drain the cabbage: A quick squeeze or letting it sit in a strainer for a minute prevents soggy buns.
Variations
- Spicy katsu breakfast sandwich: Add 1–2 teaspoons sriracha to the sauce, or stir 1/2 teaspoon chili crisp into the eggs.
- Baked “katsu”: Spray breaded cutlets with oil and bake on a rack at 425°F (218°C) for 16–20 minutes, flipping at the halfway mark, until 165°F (74°C) inside.
- Extra-creamy slaw: Add 2 tablespoons Japanese mayo (or regular mayo) to the cabbage after it rests; taste and add a tiny pinch of salt if needed.
Storage & Make-Ahead
Best fresh: This sandwich is at its peak right after frying and scrambling.
Make-ahead sauce: Store the sauce in an airtight container in the refrigerator for up to 5 days. Stir before using.
Make-ahead cabbage: The cabbage can be tossed up to 24 hours ahead. Keep refrigerated and drain well before assembling.
Leftover chicken: Cool completely, then refrigerate (airtight) for up to 3 days. Re-crisp on a rack in a 400°F (204°C) oven for 10–12 minutes (or air fryer at 375°F (190°C) for 6–8 minutes) until hot and crisp. Soft scrambled eggs do not reheat as well; if possible, cook eggs fresh.
