This miso noodle soup is the ultimate comfort in a bowl. The rich, umami packed broth is perfectly balanced with tangy rice vinegar and savoury soy sauce, while tender buckwheat noodles absorb all the delicious flavours. Fresh veggies like bok choy and mushrooms add a satisfying crunch, making this quick and nourishing soup a perfect go-to for a warm, flavourful meal in just 30 minutes.
It’s been chilly lately, And I’ve loved testing this as my go-to cozy lunch. In my experience, topping it with crispy sesame tofu adds the perfect hearty touch.
I found that miso soup can be made vegan quite easily, but it’s not always vegan when ordered at a restaurant. That’s because the broth often includes dashi (at least whenever I order it), which commonly contains fish, or even chicken or fish stock. When making miso soup at home, you can ensure it’s vegan by using water or vegetable broth instead.
Why I add noodles to my miso soup:
Short answer: it’s delicious! Slightly longer answer: buckwheat soba noodles are perfect for soup in my opinion. They have a nutty, earthy flavour that pairs beautifully with miso, and they stay pleasantly chewy instead of turning mushy. They’re quick to cook and soak up just the right amount of that savoury broth! I think just about any soup could do with an added noodle or two, but that’s just my hot take.
How to build a deeply flavourful miso soup broth
Since my miso soup is a brothy soup, it relies on a flavourful base to be so delicious! Olive oil might not be traditional in miso soup, but it adds a round, silky richness that makes the broth feel extra comforting. If you want to swap it out for a different oil like coconut or sesame, keep in mind that will lend a specific flavour. That’s not a bad thing though! I have used and enjoyed both oils myself in this recipe.
Garlic and ginger bring that irresistible fragrant kick in my opinion, while miso lends that deep umami flavour that makes every sip so satisfying. And whether you use water or vegetable broth as the base, the combination of these simple ingredients creates a soup that tastes far more complex than it looks.
It’s good for days!
Store the soup in an airtight container in the fridge for up to 3 days. For best results, store the tofu and noodles separately from the broth. You can freeze the broth for up to 3 months. It is best to freeze without the noodles and add them in fresh when reheating.
Keeping your miso magical
Miso soup is simple, but after many tests, taste tests… and more taste tests, I found it’s got its quirks. A few small tweaks can mean the difference between “meh” and “wow.” For starters, I don’t boil the miso too long; gentle heat keeps its flavour bright and if you whisk it with a splash of hot broth before adding it into the soup it keeps things smooth and silky.
Since everyone’s palates are different I am a big proponent of adjusting ingredients to your liking. However, go easy on the miso paste at first, then taste and adjust so the saltiness hits just right. And if your broth’s already salty, dilute it. Miso should be the star, not the backup singer, you feel me?

This looks like a great start to a meal. Will have to try this, but am curious which miso did you use? I have both white miso and an amber colored miso.
