Katsu curry is one of my favourite Japanese dishes, and while this version may not be 100% authentic, it really does taste authentically good. I got the idea to use sweet potato after having a smiliar katsu curry from my local Wagamama restaurant, although they use sweet potato and aubergine coated in panko breadcrumbs.
You can find katsu curry in a block form at most supermarkets. All you have to do is simply follow the instructions to make the curry sauce. There are also a variety of brands that sell katsu curry paste which is just as good. Simply follow the instructions of the paste to make the sauce.
The sweet potato adds a nice texture and sweetness to the dish, while the tofu doesn’t really add much flavour but it it does have a good texture and is a good source of protein.
