What Is Miso Soup?
Miso soup is a traditional Japanese soup with a base of miso paste (fermented soy or chickpea paste), a savory broth (usually dashi), and simple add-ins like tofu, seaweed, green onions, and hearty greens. While the authentic broth, dashi, is made with kombu (seaweed) and bonito flakes (dried fish), this recipe uses a plant-based vegetable broth for convenience and accessibility, creating a vegan-friendly alternative that retains classic flavor and nourishment.
Ingredients
- 4 cups vegetable broth (substitute dashi for a traditional flavor)
- 1 sheet nori (dried seaweed) – optional; cut into large rectangles
- 3–4 Tbsp white or yellow miso paste (fermented soy or chickpea paste)
- 1/2 cup chopped green chard (or other sturdy greens like kale or spinach)
- 1/2 cup chopped green onion
- 1/4 cup firm tofu (cubed; silken tofu for a more traditional touch)
*Optional customizations: Add steamed kale, cooked soba or rice noodles, or a dash of tamari/soy sauce for saltiness.
Ingredient Notes and Substitutions
- Miso Paste: White or yellow miso yields a gentler flavor. For a more robust soup, red miso can be used. Chickpea miso offers a soy-free option.
- Broth: Vegetable broth is quick and easy but opt for homemade or store-bought dashi for authentic Japanese taste.
- Greens: Swiss chard, kale, or spinach add nutrition and color. Choose your favorite sturdy green.
- Tofu: Firm tofu holds its shape well. Silken tofu blends luxuriously into the broth.
- Nori: Adds a saline, oceanic note; skip or replace with wakame if unavailable.
How to Make Miso Soup with Greens & Tofu
- Simmer the Broth: In a medium saucepan, bring your vegetable broth or dashi to a gentle simmer.
- Prepare Miso Paste: Place miso paste in a small bowl. Add a splash of hot broth and whisk until smooth—this prevents clumping.
- Add Veggies & Tofu: Add chopped greens, green onions, and cubed tofu to the simmering broth. Allow to cook for 5 minutes until greens are wilted and tofu is softened.
- Add Seaweed: Stir in nori and let it soften for about one minute.
- Finish with Miso: Remove the saucepan from heat. Stir in the dissolved miso mixture. Never boil miso; high heat can destroy beneficial probiotics and dull its flavor.
- Season & Serve: Taste and add more miso or a pinch of sea salt if desired. Serve hot for the best texture and flavor.
Quick Cooking Tips
- Always dissolve miso paste separately before adding to soup.
- Don’t boil miso—add it at the end off heat.
- Customize greens and tofu type as desired.
- Use a gentle hand when stirring silken tofu to avoid breaking up cubes.

About Miso: Origins, Production & Varieties
Originating in China over 1,300 years ago and introduced in Japan by Buddhist priests, miso has evolved into a culinary staple with over 1,500 varieties in Japan alone. It’s made by fermenting soybeans with salt and koji (a beneficial fungus, Aspergillus oryzae), along with cooked grains or legumes. The fermentation process ranges from a few weeks to several years, impacting flavor, aroma, and nutrient profile.
- White Miso (Shiro): Mild and subtly sweet, short fermentation. Used for delicate soups and dressings.
- Yellow Miso: Balanced flavor, versatile.
- Red Miso (Aka): Robust, salty, aged longer.
Miso is valued for flavor (umami), versatility, and potential health benefits, including probiotic content, vitamins, and minerals.
How to Store & Serve
- Store miso: In the refrigerator, tightly sealed. Lasts for months to years.
- Serve soup: Fresh and hot for best flavor and probiotic benefits.
- Pairing: Enjoy as a starter, alongside rice, salads, or as part of a Japanese-inspired meal.
