There is something wonderfully comforting about a warm bowl of miso soup. It is light enough for breakfast or lunch, yet flavorful enough to serve alongside dinner. Best of all, homemade miso soup is surprisingly simple to prepare.
This easy miso soup recipe combines savory dashi, fermented miso paste, tender tofu, wakame seaweed and fresh scallions. The result is a warm, umami-rich soup that tastes much fresher than many instant versions.
Miso soup is a traditional Japanese dish generally made by dissolving miso into dashi, a Japanese stock. Tofu, seaweed, green onions and other seasonal ingredients can be added depending on the recipe and region.
The key to great homemade miso soup is not complicated technique. It is knowing when to add the miso and avoiding a hard boil after it has been mixed into the broth.
What Is Miso Soup?
Miso soup, known as misoshiru in Japanese, is a traditional Japanese soup made primarily from miso paste and dashi broth.
Miso is a fermented paste commonly made from soybeans, salt and a grain such as rice or barley. Different varieties have different colors, flavors and levels of saltiness.
Dashi provides the savory foundation. Traditional dashi can be prepared with kombu, a type of dried kelp, and katsuobushi, or dried bonito flakes. Vegetarian and vegan versions can use kombu and mushrooms instead.
A classic bowl often includes tofu, wakame seaweed and sliced green onions. However, the recipe is flexible enough to include mushrooms, spinach, daikon, carrots or other vegetables.

Miso Soup Ingredients
Dashi
Use about 4 cups of dashi as the soup base. Homemade dashi gives excellent flavor, but prepared dashi can make this recipe much faster.
For a vegetarian version, use kombu-based or mushroom-based broth.
Miso Paste
Use approximately 3 to 4 tablespoons of miso paste for 4 cups of broth. White miso is mild and slightly sweet, while red miso has a stronger, deeper flavor. A combination of white and red miso gives a balanced flavor.
The exact amount can be adjusted according to the type of miso and your taste. A recipe from The Washington Post similarly uses 3 to 4 tablespoons of miso for 4 cups of dashi.
Tofu
Use about 6 to 7 ounces of soft, silken or medium tofu, cut into small cubes.
Silken tofu creates a delicate texture, while firmer tofu holds its shape better in the broth.
Wakame Seaweed
Dried wakame expands considerably after soaking, so you only need a small amount. About 1 tablespoon dried wakame is enough for this recipe.
Scallions
Two scallions, thinly sliced, add a fresh, slightly sharp flavor and a pop of color.
How to Make Miso Soup
1. Prepare the Dashi
Pour 4 cups of prepared dashi into a saucepan and warm it over medium heat.
If you are making dashi from scratch, traditional versions commonly use kombu and bonito flakes. Vegetarian dashi can be made with kombu and dried mushrooms.
2. Prepare the Wakame
Place the dried wakame in a small bowl and cover it with cool or lukewarm water.
Let it soak until softened, then drain it well.
Remember that dried seaweed expands as it rehydrates, so a little goes a long way.
3. Add the Tofu
Once the dashi is hot, add the cubed tofu.
Warm it gently for about 1 to 2 minutes. You do not need to aggressively boil the tofu.
4. Dissolve the Miso
This is the most important step.
Place the miso paste in a small bowl. Ladle some of the hot dashi into the bowl and whisk until the miso becomes smooth.
Pour the mixture back into the saucepan and gently stir.
This method prevents clumps of miso from remaining in the soup and distributes the flavor evenly. Similar techniques are recommended by established recipe sources.
5. Avoid Boiling the Miso
Once the miso has been added, keep the soup below a hard boil.
A gentle simmer or very low heat is enough. Several traditional preparations specifically recommend avoiding boiling after the miso is incorporated because excessive heat can affect its delicate aroma and flavor.
6. Add Wakame and Scallions
Stir in the softened wakame and sliced scallions.
Taste the soup. If you want a stronger flavor, add a little more miso by dissolving it separately in hot broth before adding it to the pot.
Serve immediately while hot.

White Miso vs. Red Miso
Choosing the right miso can completely change the character of your soup.
White miso: Mild, smooth and slightly sweet. It is a good choice if you prefer a delicate soup.
Red miso: Stronger, darker and more savory. It works well when you want a more intense flavor.
Awase miso: A blend of different miso varieties that offers a balanced middle ground.
For a family-friendly everyday soup, white or blended miso is an easy place to start.
How to Make Vegetarian or Vegan Miso Soup
Traditional dashi often contains bonito flakes, which are made from fish. That means traditional bonito dashi is not vegetarian or vegan.
For a plant-based version, use a broth made from kombu and dried shiitake mushrooms. This creates a savory base while keeping the soup free from fish ingredients. Vegetarian and vegan dashi alternatives are commonly used for miso soup.
Also check the label of your miso and prepared broth if you need to avoid specific ingredients.
Easy Miso Soup Variations
Once you understand the basic recipe, you can make many different versions.
Mushroom Miso Soup
Add sliced shiitake, enoki or cremini mushrooms for a heartier bowl.
Vegetable Miso Soup
Try spinach, carrots, cabbage, daikon or snow peas. Add firmer vegetables early enough for them to soften.
Ginger Miso Soup
A small amount of freshly grated ginger gives the broth a bright, warming flavor.
Spicy Miso Soup
Add a small amount of chili crisp, chili oil or red pepper flakes for heat.
Miso Noodle Soup
Add cooked soba, udon or rice noodles to transform the soup into a more substantial meal.
Tips for the Best Homemade Miso Soup
Do not add all the miso directly to the pot. Dissolving it in a small amount of hot broth first helps create a smooth soup.
Use the right amount of miso. Start with less and add more if necessary. Different miso pastes vary in strength and saltiness.
Do not overcook tofu. Tofu only needs to warm through.
Rehydrate wakame carefully. It expands significantly, so start with a small amount.
Taste before adding soy sauce. Miso is naturally salty, so additional salty seasonings may not be necessary.
Serve fresh. Miso soup is at its best when served soon after preparation.
Is Miso Soup Healthy?
Miso soup can fit comfortably into a balanced eating pattern. Miso is a fermented food, while tofu contributes plant protein, and seaweed and scallions add additional ingredients and flavor.
However, it is important not to assume that every bowl of miso soup is automatically low in sodium. Miso paste itself is salty, and prepared dashi or other seasonings may add more sodium. Nutrition can vary significantly depending on the ingredients and serving size.
If you are watching your sodium intake, compare labels, use an appropriate portion of miso and avoid adding unnecessary salty sauces.
Miso soup should be viewed as a flavorful part of an overall balanced diet rather than a cure-all or “detox” food.
What to Serve With Miso Soup
Miso soup pairs naturally with many Japanese-inspired dishes.
Try serving it with:
- Steamed white or brown rice
- Sushi rolls
- Teriyaki salmon
- Chicken teriyaki
- Vegetable stir-fry
- Edamame
- Japanese-style cucumber salad
- Grilled vegetables
- Soba noodles
For breakfast, a small bowl of miso soup can be served alongside rice, eggs and vegetables.
How to Store Miso Soup
For the best flavor and texture, enjoy homemade miso soup shortly after preparing it.
If you have leftovers, transfer the soup to a clean airtight container and refrigerate it promptly. Reheat gently rather than bringing it to a vigorous boil.
For the best quality, prepare only as much as you expect to eat within a short period, especially when the soup contains tofu and other perishable ingredients.
The Bottom Line
This easy miso soup recipe proves that a flavorful Japanese-inspired soup does not require complicated cooking. With dashi, miso paste, tofu, wakame and scallions, you can create a warm bowl in about 15 minutes.
The most important technique is simple: dissolve the miso separately and avoid boiling the soup after adding it. That small step helps preserve the soup’s delicate flavor and smooth texture.
Once you master the basic recipe, experiment with mushrooms, vegetables, noodles or different varieties of miso to create your own favorite bowl.
Recipe takeaway: For a quick, comforting and customizable soup, homemade miso soup is an excellent choice for busy weeknights, light lunches or a cozy Japanese-inspired meal.
