Panko is why katsu stays crunchy long after ordinary breadcrumbs have gone soft. The difference is in how the bread is made.
What is panko?
Panko is a Japanese breadcrumb made from crustless white bread baked using an electric current rather than a hot oven. The loaf cooks without forming a crust, then gets torn into large airy flakes instead of ground into powder. Those flakes are what give the coating its crunch.
Why panko stays crisper than normal breadcrumbs
The flakes are bigger, drier and full of air, so they absorb less oil and hold their structure under sauce. Standard dried breadcrumbs are dense and fine, which means they soak up fat and turn heavy within minutes of leaving the pan.
- Larger, jagged flakes give more surface area and a louder crunch
- Less oil absorbed means a lighter finished dish
- Holds up under curry sauce, which is the whole point of katsu
- Browns more evenly, so it looks better too
What to use panko for
- Chicken or pork katsu
- Tonkatsu and katsu curry
- Crispy tofu
- Topping for a gratin or baked pasta
- Binding meatballs, where it keeps them lighter
What can I use instead of panko?
There is no perfect swap, because the texture comes from the manufacturing method. The closest home version is crustless white bread, torn rather than blitzed, dried in a low oven until crisp but not coloured. Crushed cornflakes are a decent second.
- Homemade torn white bread. Dried at 140C for 15 minutes.
- Crushed cornflakes. Crunchy, slightly sweet.
- Crushed rice crackers. Very close on texture.
- Ordinary dried breadcrumbs. Works, but expect a denser coating.
Where to buy panko in the UK
Every major supermarket now stocks it in the world food aisle or with the breadcrumbs. Japanese and Chinese supermarkets sell much larger bags at better value, which matters because panko keeps well.
Frequently asked questions
Is panko gluten free?
No, not normally. It is made from wheat bread. Gluten free versions exist and are usually made from rice flour.
Is panko vegan?
Usually yes. Most panko is just flour, water, yeast and salt, but check the label as some brands add milk powder.
Can I bake panko coated food?
Yes. Toss the panko in a little oil first, or it stays pale. An air fryer at 200C gives the closest result to frying.
How should I store it?
In a sealed container in a cupboard. It absorbs moisture from the air, and damp panko will not crisp.
