A comforting miso soup enriched with sweet corn, umami-rich miso, wakame, and dashi—a fusion of Japanese tradition and summery sweetness. Golden summer corn meets umami miso in this 10-minute vegan soup that dances between sweet and savory. A taste of sunshine, even in winter. #MisoCornSoup
There used to be this little Japanese restaurant tucked into a side street in Ponsonby. Unassuming, no-frills, but packed every night with locals who knew just how special it was. Sadly, like many small gems, it closed its doors too soon. But one dish has stayed with me ever since: their miso corn soup.
Unlike the typical miso soups you’ll find around Auckland, this one had a twist—sweet corn. It was such a simple addition, but it transformed the entire experience. The way the corn’s sunshine-bright sweetness balanced the deep savoury miso, the way the wakame added that subtle brininess of the sea… it was perfection in a cup. And when the restaurant disappeared, I knew I had to recreate it in my own kitchen.
Corn, the Japanese Way
Corn might scream “summer BBQ” to most, but in Japan, it takes on many roles. You’ll find it nestled in sushi rolls, baked into Japanese-style breads, even scattered on pizzas. But in miso soup? That’s where it truly shines. The Japanese approach vegetables with reverence, often drawing out their natural sweetness and allowing their essence to meld into a dish. Corn is no exception—it adds a sweet crunch and a freshness that plays so well with the earthy umami of miso.
Why This Soup Works So Well
What keeps me making this soup over and over again is the contrast—it’s balanced yet bold, simple yet layered. Every spoonful delivers something slightly different:
Corn kernels pop with sweet, juicy goodness
Dried wakame offers a briny, silky texture reminiscent of ocean breezes
Shiro miso (white miso) brings a soft, creamy savouriness
Dashi—whether instant or homemade—creates a flavourful backdrop that ties everything together
The flavours are gentle yet memorable, and the beauty lies in its simplicity. With just a few ingredients, it becomes more than the sum of its parts.
The Corn Conundrum: Fresh, Frozen or Canned?
When corn is in season, I always reach for the fresh stuff. The kernels are plump, slightly milky, and lend a richness to the broth that frozen or canned can’t quite match. But let’s be realistic—this is New Zealand, and fresh sweetcorn isn’t always available.
Frozen corn is a brilliant stand-in, especially if you give it a little love. Just make sure to pat it dry before cooking so it doesn’t water down the broth. Canned corn? It’ll do in a pinch, though it’s a bit softer and sweeter. Whatever you choose, the secret is in letting the corn simmer briefly in the dashi—just long enough to release its sweetness and infuse the broth.
Elevating the Basic Bowl
As much as I adore the original version, there’s something satisfying about customising the soup depending on the day (or what’s in my pantry). Some days I add cubes of silken tofu for extra protein, other times I’ll slice in some shiitake mushrooms for that earthy punch. And if I’m feeling like a kick, a pinch of shichimi togarashi goes a long way.
This soup also makes a wonderful pairing. Serve it with:
Or enjoy it solo, as I often do, when I just need a little warmth and nourishment
Dashi: The Quiet Hero
You could absolutely make a batch of homemade dashi if you have the time—and I often do when making a larger Japanese meal. But for this soup, I usually turn to the pantry for an instant awase dashi (a blend of kombu and bonito) or a vegan-friendly kombu-shiitake version. The soup’s charm is its spontaneity—it comes together in under 10 minutes, yet always tastes like you’ve put in so much more effort.
A Bowl for Every Season
What began as an attempt to relive a moment from a beloved restaurant has now become a seasonal staple in my own kitchen. In the summer, I’ll grab fresh cobs from the farmers’ market and shave them straight into the pot. In the colder months, frozen corn brings a touch of warmth and sunshine. The recipe stays mostly the same, but like all great dishes, it evolves with the seasons and my mood.
It’s comforting, clean, and deeply satisfying—everything I want from a bowl of soup. But more than that, it’s a little taste of Ponsonby nostalgia that lives on in my kitchen.
Prepare dashi according to packet instructions or use homemade if you prefer.
If using fresh corn, cut kernels from the cob. If using frozen, pat them dry to avoid watering down the broth.
Rehydrate wakame in cold water for about 5 minutes, then drain and chop into bite-sized pieces.
In a medium pot, bring the dashi to a boil. Add corn and let it simmer for 5 minutes (reduce to 3 minutes for frozen corn).
Turn off the heat. Scoop some hot broth into a small bowl, dissolve the miso paste in it, then return it to the pot. (Avoid boiling after this step to preserve miso’s delicate flavour.)
Stir in the prepared wakame and serve immediately.
I lvoe the combination fo the miso with corn — they really play nicely with one another. I need to try this — fresh corn seasons starts in a week or two!
I will happily eat miso any which way, everyday! I do love incorporating seasonal summer vegetables like corn, and also tomatoes and okra when I can get them. It’s super refreshing served cold on hot days.
I would make this just with wakame. The soup itself must be very flavourful.

Yeah, sweet and savoury combo works best
