What is a Katsu Sando?

The katsu sando is a popular Japanese sandwich commonly found in convenience stores, train stations, and lunch counters. The traditional version features tonkatsu (breaded fried pork), crustless fluffy milk bread, butter, a touch of mustard, shredded cabbage, and katsu sauce.

This vegan take swaps the pork for yuba (tofu skin) that’s breaded and air-fried to mimic the texture of a cutlet. Replace dairy butter with vegan butter and choose gluten-free bread if needed to keep the sandwich both vegan and gluten-free.

Why You’ll Love This Recipe

This Vegan Katsu Sando reproduces the classic convenience-store favorite at home: crisp yuba katsu, soft crustless bread, crunchy shredded cabbage, and savory-sweet tonkatsu sauce. It’s a fast, comforting sandwich that hits the same satisfying notes as the original while remaining plant-based.

It’s perfect for anyone who misses the authentic katsu sando experience but prefers vegan ingredients—hot, crunchy, and utterly delicious.

Ingredients

Ingredients for preparing yuba tonkatsu and assembling the sandwich:

  • Yuba. Pressed yuba sheets work best.
  • Cornflakes. Finely crushed; choose gluten-free if necessary. Cornflakes give an especially crisp crust.
  • Spices. A simple seasoning of paprika, garlic powder, salt, and pepper for the coating.
  • Plant milk. Any unsweetened, unflavored dairy-free milk to moisten the yuba before coating.
  • Starch. Cornstarch or potato starch to help the coating adhere.
  • Bread. Thick, soft white bread—crusts removed—works best for a traditional sando texture.
  • Vegan butter. Bring to room temperature so it spreads smoothly.
  • Mustard. Optional, but adds a bright counterpoint to the sauce.
  • Cabbage. Finely shredded so it layers neatly inside the sandwich.
  • Tonkatsu sauce. A sweet, savory, umami-rich Japanese condiment; use to drizzle over the katsu or spread on the bread.

How to Make Vegan Katsu Sando, Step-by-Step

  1. Prepare the yuba katsu by slicing the yuba sheet to the size you want for the sandwich.
  2. Set up three shallow plates: one with cornstarch, one with plant milk, and one with finely crushed cornflakes mixed with salt, pepper, garlic powder, and paprika.
  3. Coat each yuba piece in cornstarch, dip it into the plant milk, then press it into the cornflake mixture so the crumbs adhere well. Transfer to a tray or the air fryer basket.
  4. Air-fry: lightly spray the coated yuba with oil and cook at 375°F (190°C) for 12–15 minutes or until golden and crispy. Oven: bake on a tray for about 10 minutes per side, flipping once, until crisp.
  5. To assemble: remove crusts from the bread. Spread vegan butter on both slices, add mustard to one side if using. Place the yuba katsu on the mustarded slice, drizzle with tonkatsu sauce, and pile shredded cabbage on the other slice. Close the sandwich and press under a heavy plate for about 5 minutes to compress and meld the layers.
  6. Slice in half and serve immediately.

Secrets to Success

  • If yuba is unavailable, firm tofu or a plant-based faux cutlet can be used as a substitute. Adjust coating and cook time to achieve a crispy exterior.

Serving Tips

  • Pressing the finished sandwich under a plate for a few minutes creates the authentic compact texture of a katsu sando and makes it easier to eat.

Storage Tips

  • Store leftovers wrapped in reusable wrap or in an airtight container. Reheat in an air fryer to restore crispness rather than microwaving, which can soften the crust.

Recipe FAQs

What does Katsu Sando mean?

“Katsu sando” is short for a sandwich made with katsu—breaded, fried cutlets such as tonkatsu (pork) or chicken katsu—served between slices of soft bread.

What is Yuba?

Yuba, or tofu skin, is made from the film that forms on heated soy milk. It has layered textures that crisp nicely when breaded and fried and is often found near tofu in Asian markets.

What kind of bread is best?

Choose a thick, soft, airy white bread sliced generously. Gluten-free varieties labeled as Texas toast or other thick-cut soft loaves work well for a gluten-free option.

Do I need an air fryer?

No. An air fryer crisps the coating quickly, but you can also bake the yuba in the oven following the provided instructions.
