Vegan Mushroom Miso Soup (serves 2–3)

Ingredients

Broth base

• 1 tbsp sesame oil (or neutral oil)

• 1 small onion, thinly sliced

• 3 cloves garlic, minced

• 1 tsp fresh ginger, grated

Mushrooms

• 200–250 g mushrooms (shiitake for depth, cremini or button for body)

• 1 tsp soy sauce or tamari

Soup

• 4 cups water or light vegetable stock

• 1 piece kombu (about 5 × 5 cm), optional but recommended

• 2–3 tbsp white or yellow miso paste (adjust to taste)

• 1 tsp rice vinegar or mirin (optional, for balance)

Add-ins (optional but great)

• 100 g firm tofu, cubed

• 1–2 green onions, thinly sliced

• Handful of spinach or bok choy

• Toasted sesame seeds

• Chili oil or chili flakes

Step-by-Step Instructions

1. Prepare the kombu broth (optional but recommended)

• Place kombu in cold water and let soak 20–30 minutes.

• Heat slowly until just before boiling, then remove kombu.

This adds natural umami without making the soup taste “seaweed-y.”

2. Sauté aromatics

• Heat sesame oil in a pot over medium heat.

• Add onion with a pinch of salt; cook until soft and translucent (4–5 minutes).

• Add garlic and ginger; cook 30–60 seconds until fragrant.

3. Build mushroom depth

• Add mushrooms and spread them out.

• Let them cook undisturbed for 2–3 minutes so they brown.

• Stir, then add soy sauce.

• Cook until mushrooms release moisture and become glossy and deeply aromatic.

This step is key for a rich, meaty flavor.

4. Add broth and simmer

• Pour in kombu water or vegetable stock.

• Bring to a gentle simmer (not a hard boil).

• Add tofu if using.

• Simmer 8–10 minutes to let flavors blend.

5. Add greens

• Stir in spinach or bok choy.

• Cook just until wilted, about 1 minute.

6. Add miso (very important)

• Turn heat to low.

• In a small bowl, whisk miso with a few spoonfuls of hot broth until smooth.

• Stir back into the pot.

Never boil miso — it kills its flavor and probiotics.

7. Final seasoning

• Add rice vinegar or mirin if using.

• Taste and adjust: more miso for salt, a splash of water if too strong.

To Serve

• Ladle into bowls.

• Top with green onions, sesame seeds, and a drizzle of chili oil if desired.

Flavor Tips

• Too salty? Add hot water, not more vegetables.

• Not savory enough? Add a pinch of nutritional yeast or a few drops of soy sauce.

• Extra depth: Add a small piece of dried shiitake to the broth and remove before serving.
