What Is Miso Soup?
Miso soup (味噌汁, miso shiru) is a traditional Japanese soup that’s as comforting as it is simple. It’s typically made with dashi, a light and savory broth infused with kombu (dried kelp) and bonito flakes (dried fish flakes), which gives the soup its signature rich umami depth. The dashi is then combined with miso paste — a fermented soybean paste — which adds that irresistible salty, savory, and slightly sweet flavor.
Most versions also include small cubes of tofu, rehydrated wakame seaweed, and thinly sliced scallions. You’ll often find it served alongside rice or sushi in Japanese restaurants, but it’s also a staple in home kitchens throughout Japan. Once you make it from scratch, you’ll understand why.
Miso Soup Ingredients
You only need a handful of simple ingredients to make authentic miso soup at home:
- Water: The base for your broth. Start with cold water to properly infuse the kombu.
- Kombu: Dried kelp sheets that add subtle ocean flavor and umami to the dashi.
- Bonito flakes: Dried, shaved fish flakes that deepen the flavor of the broth. (You can also use kombu and shiitake instead for a vegan version!)
- Soft silken tofu: Traditionally used for its delicate texture that contrasts beautifully with the warm broth.
- Wakame seaweed: A mild, rehydrated sea vegetable that adds a touch of minerality and texture.
- White miso paste: The star of the show — fermented soybean paste that’s smooth, mild, and slightly sweet.
- Scallions: Freshly sliced green onions that add brightness and a gentle onion flavor right at the end.

Miso Soup Tips
Here are a few helpful tips to make your miso soup turn out perfectly every time:
- Don’t boil the miso. Miso paste should never reach a full boil — high heat destroys its delicate flavor and beneficial probiotics. Gently warm the soup instead.
- Use cold water for soaking kombu. Starting with cold water helps the kombu gradually release its flavor and prevents the broth from turning slimy.
- Skip pressing the bonito flakes. When straining the dashi, let the liquid drain naturally. Pressing will release bitterness into the broth.
- Add miso with a strainer or ladle. This prevents clumps and helps it dissolve smoothly into the broth.
- Adjust the miso flavor to taste. White miso is mild and slightly sweet; for stronger umami, try mixing in a bit of red miso.
- Soak wakame just before adding. It rehydrates quickly — usually in under 5 minutes — and will continue to expand in the hot broth.
- Serve immediately. Miso soup is best enjoyed fresh. If it sits too long, the tofu and seaweed can over-soften and the flavor will dull.

Recipe Variations
Once you’ve mastered the base recipe, have fun customizing it!
- Add mushrooms: Shiitake or enoki add rich, earthy flavor.
- Stir in greens: Spinach, bok choy, or napa cabbage work beautifully.
- Use red or mixed miso: For a deeper, saltier broth with extra umami.
- Add noodles: Udon, soba, or rice noodles can make this a heartier meal.
- Include protein: Add shrimp, poached eggs, or shredded chicken for more substance.
- Top it off: Try sesame seeds, chili oil, or a drizzle of toasted sesame oil for garnish.
- Make it vegan: Use kombu and shiitake to make a plant-based dashi instead of bonito flakes.

FAQ
Yes! Instant dashi works well for busy days. Just follow the package instructions and continue the recipe from the tofu step.
White miso (shiro miso) is fermented for a shorter time and tastes mild and slightly sweet, while red miso (aka miso) is aged longer and has a stronger, saltier, and more robust flavor.
It can be — just check the label on your miso paste, as some contain barley or wheat. Look for “gluten-free” specifically if needed.
It’s best enjoyed fresh, but you can freeze just the dashi base (without tofu or miso). Add the tofu, wakame, and miso after thawing for the best texture and flavor.

Description
Learn how to make traditional miso soup with this delicious 7-ingredient recipe.
Ingredients
- 6 cups cold water
- 1 (15 grams, approximately 6 x 6”) sheet of dried kombu
- 1 1/2 packed cups (30 grams) dried bonito flakes
- 12 ounces soft silken tofu, cut into ½-inch cubes
- 4 scallions, thinly sliced
- 2 tablespoons dried wakame seaweed
- 1/3 cup white miso paste
Instructions
- Soak the kombu. Combine the cold water and kombu in a large saucepan. Let the kombu soak for 30 minutes to slowly infuse the water with flavor.
- Prepare the dashi broth. After soaking, heat the pot over medium-low until small bubbles just begin to form around the edges (do not let it boil). Use tongs to remove and discard the kombu. Increase the heat slightly until the water just reaches a simmer, then turn off the heat and add the bonito flakes. Let the flakes soak for 2 minutes for a light broth, or up to 5 minutes for a richer, more umami flavor.
- Strain the dashi broth. Line a fine-mesh strainer with a paper towel or cheesecloth. Slowly pour the broth through into a heat-safe bowl, allowing the liquid to drain naturally. (Avoid pressing on the bonito flakes, which can make the broth bitter.) Return the clear dashi to the saucepan.
- Warm the tofu and scallions. Add the tofu and half of the scallions to the broth. Warm gently over medium heat until just below a simmer — do not boil, which can break apart the tofu.
- Add the wakame. Stir in the wakame seaweed and turn off the heat.
- Dissolve the miso. Scoop the miso paste into a small fine-mesh strainer (or ladle). Lower it into the hot broth so it’s partially submerged, then use chopsticks or a fork to whisk the paste until fully dissolved.
- Adjust and serve. Taste and adjust seasoning with a touch more miso or a pinch of salt, if needed. Warm once more just until almost simmering (do not boil), then remove from heat.
- Serve. Ladle into bowls and top with the remaining scallions. Serve immediately while warm and enjoy.








it is really good
This was a great recipe, but i did use kombu for my dashi. Also, 1/2 cup dried wakame was way too much. I even expanded to 8 cups water and it was mostly seaweed. I think maybe 1/8-1/4 a cup of the stuff is what’s actually needed for 6 cups broth.
