Easy

INGREDIENTS:

2 tbsp white miso paste
200g silken tofu (cubed)
2 tbsp dried wakame seaweed
3 green onions (thinly sliced)
3 cups water or dashi stock
1 tsp low-sodium soy sauce (optional)

INSTRUCTIONS:

Rehydrate the seaweed. Place dried wakame seaweed in a small bowl of water. Let soak for 5 minutes until soft and expanded, then drain and set aside.
Heat the stock. Bring water or dashi stock to a gentle simmer in a medium pot over medium heat. Do NOT let it boil hard — that kills the probiotic benefits of miso.
Dissolve the miso. Scoop miso paste into a small ladle. Add a spoonful of hot stock, stirring until fully dissolved, then add to the pot. This prevents lumps.
Add tofu and seaweed. Gently add the cubed silken tofu and rehydrated seaweed to the pot. Stir gently so the tofu doesn’t break apart. Heat for 2 minutes.
Serve immediately. Ladle into bowls and top with green onions. Add a small dash of soy sauce if desired. Serve right away — miso soup is best fresh and hot.

💚 Why It's Good For You

Miso is a fermented food rich in probiotics that support gut microbiome health
Seaweed (wakame) is one of the best plant sources of iodine, calcium, and iron
Tofu provides plant-based protein and isoflavones linked to heart health
Low in calories — a very satisfying, light lunch option

💡 Tips & Swaps

Key tip: NEVER boil the soup after adding miso — high heat destroys the beneficial probiotics.

Vegan: Use water or kombu (seaweed) stock instead of dashi.

Customize: Add mushrooms, spinach, or corn.
