Katsu curry recipes vary a lot. Some contain coconut milk, others don’t. Jamie Oliver's contains buttermilk and creamed coconut while Wagamama's doesn't.
Some contain miso, others don’t.
This goes to show that katsu curry is very adaptable. I’ve tried many variations of these recipes.
This recipe for sweet potato katsu curry is the one my kids like the most.
What is katsu curry?
Katsu curry is a Japanese dish served with rice. Traditionally fried chicken or pork would have been served with a thick brown-coloured curry sauce.
In my healthier vegan version I’ve coated sweet potato slices in panko breadcrumbs and baked them.
It’s widely believed that curry was brought to Japan by the British in the 1800s, via India of course. Curry isn’t traditional Japanese food but it’s widely popular there today.
This article in Vice talks about how curry was popularised in Japan by the army. It was an easy and neutral food to serve. The same applied in the British and Japanese army
And perhaps that’s why katsu curry is usually made with curry powder, rather than a complex homemade spice blend. It was all about ease.
How difficult is sweet potato katsu curry to make?
It’s not a difficult recipe to make but coating the sweet potato slices in panko breadcrumbs takes time.

What to serve with your sweet potato katsu curry
I usually serve our sweet potato katsu curry with rice - either brown or white - and some pickles.
It’s lovely with pickled cucumber or radish. But if you don’t like pickles some sliced cucumber or other veggies go well - it’s nice to have a fresh crunch on the side of the curry.
I also like to sprinkle some sesame seeds over my katsu curry.

Sweet potato katsu curry
Ingredients
For the sweet potatoes
- 2 medium sweet potatoes peeled and sliced
- Small bowl of plain white flour
- Small bowl of dairy free milk
- Small bowl of panko breadcrumbs
For the sauce
- 2 tablespoons sunflower or vegetable oil
- 1 onion chopped
- 1 carrot diced
- 2 clove garlic chopped
- 1 inch chunk ginger peeled and chopped
- 2 tablespoons mild curry powder
- 1 tablespoon plain flour
- 500 ml veg stock
- 1 tablespoon soy sauce
- 1 tablespoon maple syrup
Instructions
To make the sweet potatoes
- Preheat the oven to 200°C (fan)/220°C/gas mark 7. Line two baking trays with non-stick baking paper.
- Peel and thinly slice 2 medium sweet potatoes.
- Dip into the plain flour, then the dairy free milk then into the panko breadcrumbs. Ensure that both sides are coated.
- Place on the baking tray and repeat with the remaining slices. Refill your flour, milk and panko breadcrumbs as needed. You may find you get bits of lumpy flour in the milk which you will need to remove and discard.
- When done bake in the oven for 10-15 minutes on each side, or until cooked through and turning golden brown. Cooking time will depend upon the thickness of your slices.
To make the katsu curry sauce
- Heat 2 tablespoons sunflower oil in a large saucepan.
- Add 1 chopped onion and 1 diced carrot. Stir, cover with a lid, and reduce the heat to low. Sweat for 10-15 minutes, stirring occasionally, until soft.
- Add 2 cloves chopped garlic and a 1 inch piece of chopped ginger. Stir and cook for one minute.
- Add 2 tablespoons mild curry powder and 1 tablespoon plain flour. Stir well.
- Gradually add 500ml vegetable stock, a little at a time, stirring as you go. This will help it remain thick.
- Bring to boil, then reduce to a simmer. Add 1 tablespoons soy sauce and 1 tablespoons maple syrup.
- Allow to cool slightly then blend with a handheld blender or transfer to a jug blender. Blend until smooth, then return to the pan and reheat.
To serve
- When the sweet potato slices are cooked serve with katsu sauce poured over the top, some rice, sesame seeds, and some sliced cucumber or pickles on the side.

I make this recipe at least once a fortnight! it’s such a wonderfully easy one too! Everyone who tries it says how yummy it is.
One evening I ran out of panko breadcrumbs and only had golden breadcrumbs in my cupboard, these worked very well too. They gave the sweet potato nuggets a crispier bite. I also used this recipe with courgette which worked surprisingly well too.
Mandy Mazliah
So glad you enjoy this Jo - it's one of our favourites too. I'll have to give it a try with courgette
William E J. Foxall
Super dish and very tasty, While cutting and coating the sweet potato you can do enough to freeze and use at a later date
Mandy Mazliah
Glad you enjoyed it William - great tip
Rebecca Beesley
Loved how well the panko coated sweet potato turned out!!! What a great idea to do flour/milk alternative/ breadcrumbs instead of using egg which so many breadcrumbed recipes seem to rely on. I used hazelnut milk. I've missed katsu curry so much since I stopped eating meat 2.5 years ago so I'm thrilled to have found this recipe!!! It's amazing and my kids enjoyed it too.

This katsu curry really was incredible. The recipe was super easy to follow and you were definitely right about the coating the sweet potatoes part. The sauce was so easy and so perfect. Loved the cucumbers too. Worked really well as a balance. Highly recommend giving this a go. My kids lapped it up.
