Pork Miso Soup (Tonjiru)

Tender pork belly and soft tofu stewed in a sweet onion and miso broth. This winter warming Pork Miso Soup requires a bit of patience but trust me, it’s worth it. The broth gets thick and is more like a stew than a soup and tofu isn’t your thing, just add more pork!

Why I Love This Recipe

The recipe is inspired by a bowl I had in Niigata, Japan, and it was love at first sip. It was the tastiest bowl of Tonjiru I ever had, sooo perfect and cosy for when it’s snowing outside or in the depths of a British winter. I knew I had to recreate something similar and this is what I came up with. It’s also got my Grandma’s seal of approval, so I’m happy with it.

Frequently Asked Questions

What is Tonjiru?

Tonjiru is a Japanese stew like dish with made with pork and miso paste. You will often find other vegetables in it like burdock root, daikon or carrots. This version only has onions but feel free to add in more veg. Root vegetables work best with this soup.

Can I make this Vegetarian/Vegan?

You can by omitting the pork and dashi stock but they both add a lot of flavour. If you can source vegetarian/vegan dashi then that would be good.

I can’t find thinly sliced pork belly, what do I use instead?

Use whatever you can find. If you are using a thicker cut of pork, add it in earlier so it has a chance to become soft and tender. A tip for thinly slicing pork belly – freeze the pork for approximately 45 minutes and slice as thin as possible using a sharp knife.

  • 1.4 litres of Dashi Stock (Japanese soup stock).

Notes

In this recipe I use thinly sliced pork belly which is very common in Japanese supermarkets. As an alternative I would use regular pork belly and freeze it for about 45mins then slice it as thinly as possible and add it into the pan 30 minutes after the onions have been added.
If you wanted to make Dashi from scratch here is a recipe for homemade Dashi by Just One Cookbook, a trusted Japanese home cooking blog. Make 1.4 litres of Dashi using this recipe and use it instead of the water.

What to Eat with Pork Miso Soup?

A bowl of white rice or Japanese Mushroom Rice goes super well with this soup. If you want something fresh to go with it, a Sesame Cucumber Salad would work nicely too!
