There's something about a warm bowl of miso soup recipe made from scratch that just hits different. I remember the first time I tried making it at home — I was honestly nervous. Like, could I really pull off something I'd only ever ordered at Japanese restaurants? Turns out, yes. And it was way easier than I expected.
This homemade miso soup comes together with just 6 simple ingredients. We're talking real dashi broth, silken tofu, white miso paste, and fresh scallions. It takes about 25 minutes from start to finish, and most of that is just letting things simmer. Emily actually asks for this on chilly weeknights now, which is a win in my book.
If you're into cozy, warming soups, you might also love my Coconut Curry Carrot Soup — it's another one of those bowls that just makes everything feel better.

Ingredients for Homemade Miso Soup
For the Dashi
- 4 cups water
- 1 (3-inch) piece kombu (dried black kelp)
- ½ cup loosely packed dried bonito flakes (katsuobushi)
For the Miso Soup
- 3 tablespoons white miso paste
- 6 ounces silken tofu, drained, cut into very small cubes (¼-inch to ½-inch)
- 2 medium scallions, diced very small, divided
Quick note: White miso paste gives this soup a mild, slightly sweet taste. You can find it at most grocery stores in the international aisle or at any Asian market. If you can only find red miso, use about 2 tablespoons instead of 3 — it's much saltier.
How to Make Miso Soup From Scratch
Making authentic Japanese miso soup at home is simpler than you'd think. The key is getting the dashi right first. Here's how I do it:
Prepare the Dashi Broth
- Combine water and kombu in a medium pot over medium heat. Keep an eye on it — you want to remove the kombu right before the water starts boiling. (If you let it boil with the kombu still in there, the broth turns bitter. I learned this the hard way my first try!)
- Add the bonito flakes once the kombu is out. Let the water come to a boil, then simmer for about 1 minute.
- Remove from heat and let the bonito steep for an additional 5 minutes. Think of it like brewing tea — you're letting all that savory flavor soak into the water.
- Strain the bonito from the dashi and toss the flakes. Add more water if needed to bring it back to 4 cups.
Finish the Miso Soup
- Pour the dashi back into the pot and bring it to a gentle simmer over medium to medium-high heat.
- Dissolve the miso paste — this step matters! Place the white miso paste in a small bowl or measuring cup. Scoop out about ½ cup of the hot broth and pour it over the miso. Whisk until completely smooth with no lumps left. Then pour the dissolved miso back into the simmering broth.
- Add the tofu and half the scallions. Reduce heat to medium-low and gently simmer for 1 to 2 minutes — just long enough to warm everything through. Do not boil the miso once it's been added.
- Serve immediately. Pour into bowls and scatter the remaining scallions on top.
See? Not complicated at all. The whole thing takes about 25 minutes, and most of that is hands-off time.
Storage and Reheating Tips
Miso soup is honestly best when served fresh. The miso tends to settle as it sits, and the tofu gets a little soft if it hangs out in the broth too long.
That said, if you do have leftovers, store them in an airtight container in the fridge for up to 2 days. When you reheat, keep the heat low and stir gently. Never bring it to a boil — boiling kills the beneficial probiotics in the miso and makes it taste flat.
One thing I've noticed? The flavors actually deepen a bit overnight. So leftover miso soup isn't a bad thing at all. Just be gentle with the reheat.
Variations and Tips for Your Miso Soup Recipe
Have you ever thought about customizing your miso soup? Here are some ideas I've tried:
- Add wakame seaweed — just soak dried wakame in water for 5 minutes, chop it up, and add it with the tofu. It gives the soup that classic restaurant look.
- Swap the protein — try small shrimp or thinly sliced mushrooms instead of tofu if you want something different.
- Make it heartier — toss in some cooked soba noodles or udon for a more filling meal.
- Try different miso pastes — yellow (shinshu) miso is a nice middle ground between white and red.
- Don't skip the dashi — I know it's tempting to just use water, but the kombu and bonito are what give this soup its depth. Trust me on this one.
Big tip: Always dissolve the miso in a small amount of broth before adding it to the pot. Dumping it straight in leads to clumps, and nobody wants lumpy soup.
Frequently Asked Questions About Miso Soup
Yes, but red miso has a stronger, saltier flavor. Start with less and adjust to taste.
Dashi is essential for authentic flavor, but in a pinch, you can substitute vegetable broth for a simpler version.
Refrigerate in an airtight container for up to 2 days. Reheat gently over low heat—never boil, as boiling ruins the miso's flavor and probiotics.
Boiling destroys miso's delicate flavor and kills its beneficial live cultures (probiotics), resulting in a flat-tasting soup.

Ingredients
Equipment
Method
- Make the dashi: Combine the water and kombu in a medium pot over medium heat. Remove the kombu just as the water starts to come to a boil (don't let it boil or the flavor will be bitter.) Add the bonito flakes and let the water come to a boil. Simmer for about 1 minute, then remove the pot from heat and let the bonito steep for an additional 5 minutes. Strain the bonito from the dashi and discard. Add additional water, if necessary, to make 4 cups.
- Pour the dashi back into the pot and bring to a gentle simmer over medium/medium-high heat.
- Place the miso paste in a small ramekin or measuring cup. Scoop out about ½ cup of the hot broth and pour it over the miso; whisk until the miso is entirely dissolved in the water and no lumps remain. Then pour the dissolved miso back into the simmering broth.
- Reduce the heat to medium-low. Add in the tofu and half of the scallions; gently simmer just enough to warm through, 1 to 2 minutes. (Do not boil the miso once the tofu has been added.)
- Pour the miso soup into individual bowls and scatter the remaining scallions over the top. Serve right away.
