This miso soup is the one I make when I need something warm, quick, and a little bit healing.
It takes about 25 minutes from start to finish, and most of that is just letting the dashi steep.
If you have never made Japanese soup at home before, this is a great place to start.
Just a handful of ingredients turn into something that tastes like it came from a restaurant.
I first learned this recipe after ordering miso soup at nearly every Japanese restaurant I visited for years.
Eventually I got curious enough to make my own, and once I figured out the dashi step, I realized how simple the whole thing actually is.

Why You’ll Love This Miso Soup Recipe
This soup comes together with only a handful of ingredients, and most of them keep in your pantry or freezer for months.
It is also endlessly flexible, so you can add whatever vegetables or protein you have on hand.
Once you know how to make dashi, you have the base for dozens of Japanese dishes.
It is also a genuinely comforting bowl of food, the kind you want when you are feeling a little run down.
- Ready in about 25 minutes, most of it hands off
- Only 6 main ingredients, all shelf stable except the tofu
- Naturally dairy free and easy to make gluten free
- A light starter or a full meal with rice on the side
- Endlessly customizable with different vegetables and proteins
My favorite way to round out a Japanese inspired dinner is to serve this alongside Hawaiian Shoyu Chicken and a bowl of steamed rice.
Ingredients
Traditional miso soup relies on just a few core building blocks: dashi, miso paste, tofu, wakame, and scallions.
Here is exactly what you need and why each ingredient matters.
- 4 cups water
- 1 piece (about 4 inches) kombu, wiped clean with a damp cloth
- 1 cup loosely packed bonito flakes (katsuobushi)
- 3 tablespoons white miso paste, plus more to taste
- 7 ounces soft or silken tofu, cut into small cubes
- 2 tablespoons dried wakame seaweed
- 2 scallions, thinly sliced
If you already have miso paste like the kind used in my Seeded Miso Sweet Potato Bread, you can put a portion of it to use here too.
Kitchen Equipment Needed
You do not need anything fancy to make this soup, and you probably already own most of it.
A couple of specialty tools do make the process smoother, though.
- Medium saucepan or pot
- Miso strainer or muddler, for dissolving the paste smoothly
- Fine mesh strainer, for straining the finished dashi
- Ladle
- Sharp knife and cutting board, for the tofu and scallions

Recommended Products for This Recipe
These are a few products I personally keep stocked in my pantry for making Japanese style soups and broths.
None of these are required, but each one makes the process a little easier or the final bowl a little more authentic.
1. Miso Master Organic White Miso Paste
This is the miso I reach for most often because it has a mellow, slightly sweet flavor that works well even for people who are new to miso soup.
It dissolves easily and gives the broth a rounded, savory finish without being overly salty.
2. Kayanoya Dashi Stock Powder
On busy weeknights, this instant dashi powder saves a solid twenty minutes compared to making dashi from scratch.
The flavor is close enough to homemade that I keep a jar in my pantry at all times.
3. Japanese Miso Muddler and Strainer Set
This little tool makes a real difference in texture.
Instead of whisking miso paste directly into the pot and risking clumps, you press it through the mesh so it dissolves completely smooth.
4. Premium Kombu Dried Kelp
Good kombu makes a noticeably cleaner tasting dashi than the lower grade pieces sometimes found at regular grocery stores.
A single bag lasts a long time since you only need a small piece per batch.
5. Dried Wakame Seaweed
This is one of those ingredients that transforms a basic broth into something that actually looks and tastes like restaurant miso soup.
A little goes a long way, so one bag will last you many batches.
For another quick Asian style sauce to keep on hand, I would also recommend my Teriyaki Sauce Recipe, which uses several pantry staples in a similar way.
Step-by-Step Instructions: How to Make Miso Soup
1. Soak the Kombu
- Wipe the kombu gently with a damp paper towel to remove any surface dust, but do not rinse it under running water since that removes flavor.
- Place the kombu in a medium saucepan with the 4 cups of water.
- Let it soak at room temperature for at least 30 minutes, or refrigerate it and let it soak for up to several hours if you have the time.
- This soaking step slowly draws out the natural glutamates from the kombu, which gives the dashi its savory backbone.
2. Make the Dashi
- Place the saucepan with the kombu and water over medium heat.
- Heat gently until small bubbles just begin to form around the edges of the kombu, which takes about 7 to 10 minutes.
- Remove the kombu from the pot right before the water reaches a full boil, since boiling the kombu can make the dashi taste bitter and slimy.
- Raise the heat and bring the water to a full boil, then turn off the heat completely.
- Add the bonito flakes and let them steep undisturbed for about 2 minutes.
- Strain the dashi through a fine mesh strainer into a clean bowl, pressing very lightly on the bonito flakes to release the liquid without pressing so hard that the dashi turns cloudy.
- Discard the spent bonito flakes, or save them to make a quick furikake topping another time.
3. Rehydrate the Wakame
- While the dashi is steeping, place the dried wakame in a small bowl and cover it with cold water.
- Let it soak for about 5 to 10 minutes, until it softens and expands noticeably.
- Drain the wakame well and set it aside until you are ready to add it to the soup.
4. Warm the Dashi and Add the Tofu
- Pour the strained dashi back into the saucepan and place it over medium heat.
- Bring it just to a gentle simmer, not a rolling boil.
- Carefully add the cubed tofu to the simmering dashi.
- Let the tofu warm through for about 1 to 2 minutes, stirring very gently so the cubes do not break apart.
5. Dissolve the Miso Paste
- Reduce the heat to low so the dashi is barely simmering.
- Place the white miso paste in a mesh strainer or miso muddler and lower it into the hot dashi.
- Use the back of a spoon to press and stir the miso through the mesh until it fully dissolves into the broth.
- Taste the soup and add a little more miso paste if you prefer a stronger, saltier flavor.
- Do not let the soup return to a boil once the miso is added, since high heat can dull its flavor and destroy some of its beneficial enzymes.
6. Add the Wakame and Scallions
- Stir the drained, rehydrated wakame into the pot.
- Turn off the heat completely.
- Divide the sliced scallions among your serving bowls.
- Ladle the hot soup over the scallions in each bowl.
- Serve immediately while the soup is at its hottest.
For a similar technique with a different broth base, take a look at my Chicken Egg Drop Soup Recipe, which uses the same gentle, low heat approach to protect delicate ingredients.
Tips for The Best Miso Soup
A few small details separate good miso soup from great miso soup. None of these tips take extra time, they just require a little attention.
- Never let the soup boil after you add the miso paste, since heat breaks down its flavor and nutrients
- Taste as you go and add miso gradually, since saltiness varies a lot between brands
- Cut the tofu gently and add it late so the cubes hold their shape
- Use room temperature or cold water for soaking the kombu rather than hot water, which draws out bitterness
- Make a double batch of dashi and freeze half for a faster soup next time
If you like building your own Japanese style pantry staples, my Japanese Curry Chicken Recipe uses several of the same techniques for building deep flavor from simple ingredients.
Serving Suggestions
Miso soup is traditionally served as part of a larger meal rather than on its own.
That said, it also works perfectly as a light lunch by itself.
- Serve alongside steamed white rice and a few pickled vegetables for a classic Japanese breakfast
- Pair it with Baked Teriyaki Chicken and rice for a complete dinner
- Add a side of gyoza or spring rolls for a heartier meal
- Spoon it over soba or udon noodles for a quick noodle soup
- Serve it as a starter before sushi or a stir fry dinner
Variations of Miso Soup
Once you understand the basic method, miso soup becomes a template you can adjust endlessly based on what you have in the fridge.
Here are a few of my favorite variations.
- Swap white miso for red miso or a mix of both for a deeper, more robust flavor
- Add sliced mushrooms, daikon, or napa cabbage along with the tofu
- Stir in a handful of baby spinach or bok choy right at the end
- Use vegetable dashi instead of bonito based dashi for a fully vegetarian version
- Add a soft boiled egg for extra protein and richness
If you enjoy soups built from a savory broth base, my Wonton Egg Drop Soup Recipe follows a similarly simple build and swap approach.
Storage and Reheating
Miso soup is best enjoyed fresh, but leftovers still hold up reasonably well for a day or two.
The main thing to watch for is how you reheat it.
- Store leftover soup in an airtight container in the refrigerator for up to 2 days
- Reheat gently over low heat on the stovetop, stirring occasionally
- Avoid microwaving on high power, since it can cause the soup to boil unevenly
- Never let the soup come to a full boil while reheating, to protect the miso flavor
- Miso soup does not freeze well, since the tofu texture changes significantly once thawed

Nutritional Facts
Miso soup is naturally light, which is part of why it works so well as a starter or a simple lunch.
Here is a general estimate for one serving of this recipe, based on four servings total.
- Calories: about 70 to 90 per serving
- Protein: about 6 to 8 grams per serving
- Total Fat: about 2 to 3 grams per serving
- Carbohydrates: about 5 to 7 grams per serving
- Sodium: about 600 to 750 milligrams per serving
These numbers will shift depending on the exact brand of miso you use and how much tofu you add.
If you are watching sodium closely, my Asian Beef Noodle Soup includes a similar note on adjusting salt to taste.
Health Benefits of Key Ingredients
Beyond tasting good, miso soup brings a handful of genuine nutritional benefits to the table.
Each core ingredient contributes something different.
- Miso is a fermented food that contains natural probiotics, which support gut health
- Tofu is a complete plant protein and provides calcium and iron
- Wakame seaweed is rich in minerals like iodine and magnesium
- Kombu contains natural glutamates along with trace minerals
- Scallions add small amounts of vitamin C and antioxidants

FAQs About Miso Soup
1. Can I make miso soup without kombu and bonito flakes?
Yes, instant dashi granules are a convenient substitute and work well in a pinch.
Simply dissolve the granules in hot water according to the package directions and use that as your dashi base.
2. Why should I not boil the soup after adding miso?
Boiling miso paste can break down its delicate flavor compounds and destroy some of the beneficial live cultures it contains.
Keeping the heat low after adding miso preserves both the taste and the nutritional benefits.
3. What is the difference between white and red miso?
White miso is fermented for a shorter time and has a milder, slightly sweet flavor.
Red miso ferments longer and has a bolder, saltier, more intense taste.
4. Can I make this recipe vegetarian or vegan?
Yes, simply use kombu based dashi or a vegetable stock instead of bonito flakes.
The rest of the recipe is already plant based as written.
5. How long does homemade dashi last in the fridge?
Homemade dashi keeps well in an airtight container in the refrigerator for up to one week.
You can also freeze it in small portions for up to a month.
For another naturally plant based soup, check out my Potsticker Soup Recipe, which uses a similar light broth approach.
