Seaweed Miso Soup

Mum's Kitchen Series: A simple and nourishing seaweed miso soup that is deeply rooted in Asian Culture. It comes together in 15 minutes -- packed with plant-based goodness and versatile enough to become your new favourite weeknight staple. Drink it as it is, or transform it into a full noodle bowl. The possibilities are endless.

A Little Note Before We Begin

This is one of those recipes that feels like a warm hug in a bowl. It is simple, honest, and quietly powerful — much like the ingredients themselves. I came to appreciate this soup even more deeply during my recovery, when my body was craving gentleness and nourishment in equal measure. It became a staple in my kitchen, and I hope it finds its way into yours too.

This is also one of the first recipes I want to leave in my cooking library — because it is the kind of thing you can make in fifteen minutes on a tired evening, and still feel like you've done something genuinely good for yourself.

Soup & the Soul — A Chinese Upbringing

Growing up in a Chinese family, soup was never just a dish. It was a daily ritual, a form of care, and a quiet language of love. There was almost always a pot of something simmering on the stove — and whether you were tired, unwell, or simply hungry, soup was the answer.

That upbringing stayed with me. And during the hardest days of my treatment, when my appetite had all but disappeared and eating felt like an effort, it was soup that I turned to. I couldn't manage much — but I could always sip a little soup. It asked nothing of my body, and gave everything back. Gentle, warming, and deeply nourishing — it was exactly what I needed.

In Chinese culture, soup is considered deeply healing. It is easy on the digestive system, hydrating, and a wonderful vehicle for nutrients. It is no coincidence that so many Asian medicinal traditions begin with a bowl of something warm and slow-cooked. Soup is wisdom in liquid form.

A Soup Rooted in Asia

Seaweed has been a cornerstone of Asian cooking for thousands of years — and for good reason. Long before the world caught on to the idea of superfoods, coastal communities across Japan, Korea, and China were quietly building their health on the back of this humble ocean plant.

Here are a few fun facts that I love:

• In Korea, seaweed soup (miyeok-guk) is traditionally eaten on birthdays. The custom traces back to the belief that new mothers should eat seaweed soup after giving birth to replenish their nutrients — so on your birthday, you drink it in gratitude to your mother. How beautiful is that?

• In Japan, wakame has been cultivated and eaten for over 1,000 years. It features in everything from miso soup to salads, and is considered a symbol of health and longevity.

• In Chinese culture, seaweed is believed to have cooling properties that help balance the body's internal heat — a concept deeply rooted in Traditional Chinese Medicine.

• Globally, seaweed is one of the most sustainable foods on the planet — it requires no fresh water, no fertiliser, and actually helps improve ocean health as it grows.

Why Seaweed Matters — Especially for Vegans

One of the things I became much more conscious of during my recovery was making sure my vegetarian diet wasn't leaving any nutritional gaps. Seaweed turned out to be one of the most valuable additions I could make.

Here is why it deserves a regular spot in your kitchen:

• Iodine — This is the big one. Iodine is essential for healthy thyroid function, which in turn regulates your metabolism and energy levels. It is notoriously difficult to get from plant foods alone, making seaweed one of the few reliable plant-based sources. A small serving of wakame a few times a week is generally considered a reasonable amount. If you enjoy nori — the thin sheets used in sushi — a few sheets a day is typically fine too. As with most things, moderation is key; iodine is best consumed in consistent, moderate amounts rather than in excess.

• Calcium — Important for bone health, and often a concern for those on a plant-based diet. Seaweed contributes a useful amount.

• Iron — Another nutrient that vegans need to be mindful of. Seaweed offers a plant-based source, and pairing it with vitamin C-rich foods helps your body absorb it more effectively.

• Antioxidants & Anti-inflammatory compounds — Seaweed is rich in these, which support the immune system and overall cellular health — something I was very focused on during and after my treatment.

• Gut health — The natural fibre in seaweed acts as a prebiotic, feeding the good bacteria in your gut. A happy gut is the foundation of so much else.

The Recipe

Seaweed Miso Soup

Serves 2 | Ready in 15 minutes

This is an easy soup base to master. Once you're comfortable with it, the variations are endless — and that's where the fun begins. Adding sautéed onion, carrots or celery will deepen the aroma and bring a lovely extra layer of umami.

Ingredients

• A pinch of dried wakame seaweed

• A pinch of dried mekabu seaweed

• 1½ cups water

• 1 tsp red miso paste dissolved in ½ cup hot water

• ½ block soft tofu, cubed

• 1 tsp mirin

• 1 tsp soy sauce

• Pinch of salt, to taste if needed

Method

1. Bring the water to a boil in a pot.

2. Rinse the seaweed and soak in cold water for 5 minutes, then drain.

3. Dissolve the red miso paste in ½ cup of hot water and set aside.

4. Add the drained seaweed to the boiling water and cook for 2 minutes.

5. Add the mirin, soy sauce and miso mixture. Stir gently.

6. Add the tofu cubes.

7. Turn off the heat, place the lid on and leave for 2 minutes.

8. If you love spring onions, don't hold back. Add a generous pinch on top before serving. It lifts the whole bowl beautifully.

9. Serve hot and enjoy.

Tips & Variations

One of the things I love most about a good soup base is its versatility. This seaweed miso soup is no exception — drink it just as it is, or use it as a foundation for something more. Here are some of my favourite ways to take it further:

Drink it as it is Sometimes the simplest version is the best. A quiet bowl of this soup, on its own, is deeply satisfying and wonderfully restorative.

As a Japanese-style noodle base It works beautifully with udon or ramen noodles. To bring out that distinctly Japanese flavour, add a little more mirin and soy sauce — that combination is the secret to making everything taste like it came straight from a Japanese kitchen. Adjust to taste as you go.

As a Chinese-style noodle base For Chinese noodles, I'd swap the mirin for a touch more soy sauce and finish with a drizzle of sesame oil. It completely transforms the character of the soup — deeper, nuttier, and wonderfully comforting.

Add what you love Fried tofu, shitake mushroom, corn, spinach, or any greens you have on hand all work beautifully. For a vegetarian (non-vegan) option, a jammy soft-boiled egg on top adds richness and makes the soup feel even more satisfying.

Make more, store more Soup is one of the most practical things you can have in your kitchen. Make a larger batch, freeze it in portions, and you'll always have a nourishing base ready to go — whether it's a quick weeknight dinner or the foundation for something more creative. The possibilities really are endless.

A Closing Thought

Food, at its best, is medicine. It is memory. It is love made tangible. This little bowl of soup carries all of that for me — and I hope, in some small way, it does the same for you.

Cook it with love. Share it with light.
