Oh my gosh, you have to try this miso mushroom soup. It is my absolute go-to for when I need a hug in a bowl, and I’m telling you, it comes together in like 15 minutes flat. I first fell in love with it on a chilly, rainy afternoon when I was desperate for something savory and fast. The combo of earthy mushrooms and that deep, umami-rich miso is just magic. A handful of fresh scallions on top at the end? Perfection. It’s the kind of simple, cozy dish that just makes everything feel right.

Ingredients for Miso Mushroom Soup with Scallions

Let’s talk about what makes this soup so darn good. You’ll need just a handful of ingredients—trust me, it’s all about quality over quantity here. Here’s what you’ll need:

4 cups vegetable broth – homemade or store-bought, both work great.
1 cup sliced mushrooms – I love shiitake for their deep flavor, but button or cremini mushrooms work too.
3 tbsp miso paste – I use white miso for its mild sweetness, but red miso will give you a bolder flavor if that’s your thing.
2 scallions, chopped – save some for কিনা for garnish if you’re feeling fancy.
1 clove garlic, minced – because garlic makes everything better.
1 tsp grated ginger – fresh is best, but a squeeze of ginger paste works in a pinch.
1 tbsp soy sauce – opt for low-sodium if you’re watching your salt intake.
1 tsp sesame oil – just a drizzle gives it that nutty, toasty finish.

That’s it! Seriously, this soup is so simple, but the flavors are anything but. If you’re feeling adventurous, you can swap in tofu for extra protein or add a splash of rice vinegar for a tangy kick. But honestly, it’s perfect as-is—just trust me on this one.

How to Make Miso Mushroom Soup with Scallions

Okay, here’s where the magic happens—and trust me, it’s way easier than you’d think for how flavorful this soup turns out. Just follow these simple steps, and you’ll be sipping umami heaven in no time.

Sautéing the Aromatics

First things first: grab your favorite soup pot and set it over medium heat. Add that glorious teaspoon of sesame oil—careful, it sizzles fast! Once it’s shimmering (about 30 seconds), toss in your minced garlic and grated ginger. Now, lean in close and breathe deep. When you catch that incredible spicy-sweet aroma rising up after about a minute? That’s your cue. Don’t let them brown, though—we’re just waking up their flavors!

Cooking the Mushrooms

Next comes my favorite part—those mushrooms! Slide them right into the pot and give everything a good stir. You’ll hear this amazing sizzle as they hit the hot oil. Let them work their magic for 3-4 minutes, stirring occasionally. Watch how they transform from pale and firm to golden and slightly shrunken. That’s when you know they’ve given up their earthy goodness to the pot.

Simmering the Soup

Time for the broth! Pour in all 4 cups of vegetable broth and crank the heat up just until it starts bubbling gently at the edges. Now, here’s my grandma’s trick: scoop out about ½ cup of hot broth into a small bowl and whisk your miso paste into it until totally smooth. This prevents those pesky miso clumps! Pour it all back into the pot along with the soy sauce. Let everything mingle and get happy over low heat for about 5 minutes—just until the flavors marry.

Finishing with Scallions

The grand finale! Right before serving, stir in those vibrant chopped scallions—reserve a pinch for garnish if you’re feeling fancy. The heat will soften them just slightly while keeping that fresh crunch. Pro tip: if you add them too early, they’ll lose their bright color and flavor, so timing is everything here!

Why You’ll Love This Miso Mushroom Soup

Listen, I make this soup at least once a week—sometimes twice if I’m feeling extra cozy—and here’s why I think you’ll become obsessed too:

It’s stupidly fast. Seriously, 15 minutes from chopping to slurping. When you’re hangry or just need warmth now, this is your lifeline.
Vegetarian comfort food that doesn’t taste “healthy.” No sad, bland broth here. The miso and mushrooms pack so much savory depth, you won’t miss meat at all.
Umami bomb alert! Between the fermented miso, earthy mushrooms, and soy sauce, every spoonful is like a flavor firework. Your taste buds will throw a party.
Crazy customizable. Swap mushrooms, add tofu, toss in noodles—it’s forgiving. I’ve even thrown in leftover spinach when I needed to clean out the fridge.
Feels fancy but costs pennies. Impress guests or treat yourself without breaking the bank. Bonus: it smells like a professional kitchen while cooking.

Honestly? The first time I made this, I texted three friends immediately like, “YOU NEED THIS IN YOUR LIFE.” Now it’s their go-to soup too. That’s the power of mushroom-miso magic.

Tips for the Best Miso Mushroom Soup with Scallions

Alright, let me spill all my secrets—the little tricks I’ve picked up after making this soup approximately a zillion times. These tips take it from “good” to “oh-my-gosh-what-sorcery-is-this” levels of deliciousness.

Handle that miso with care

Here’s the golden rule: never let miso boil. I learned this the hard way when I once got distracted and ended up with a weirdly bitter soup. Miso’s delicate fermented flavors break down at high heat. Always dissolve it in a bit of warm broth first, then stir it in at the end off the heat. Your taste buds will thank you.

Mushroom matters

Don’t crowd the pan when sautéing! If you dump all the mushrooms in at once, they’ll steam instead of getting that gorgeous golden color. Give them space to breathe—I sometimes do two batches if I’m using a small pot. And here’s a game-changer: save a few raw slices to toss in right before serving for contrasting texture.

Scallion strategy

I separate the white and green parts—the whites go in with the garlic and ginger for foundational flavor, while the greens stay crisp as a finishing touch. And if you really want to wow people? Cut them on a sharp diagonal. It looks fancy and exposes more surface area for flavor.

Broth boosters

If your vegetable broth is kinda meh, try this: steep a dried shiitake mushroom in the warm broth for 10 minutes before starting. Remove it before adding the fresh mushrooms—instant umami upgrade! A tiny splash of mirin or rice vinegar can also brighten everything up if the flavors feel flat.

Leftover magic

This soup thickens in the fridge (thank you, miso!), so when reheating, add a splash of water or broth to loosen it up. And don’t panic if the scallions lose their vibrancy—just sprinkle fresh ones on top to revive that pop of color and crunch.

One last thing: trust your instincts! I’ve made this in dorm rooms, fancy kitchens, and even camping (don’t ask). The soup adapts—just keep tasting and adjusting until it makes you do that happy little soup dance.

Variations of Miso Mushroom Soup

One of the best things about this soup? It’s like a blank canvas for your cravings. I’ve tweaked it a million ways depending on my mood or what’s lurking in my fridge. Here are some of my favorite twists—feel free to get creative and make it your own!

Protein power-ups

If you’re feeling fancy or just need a heartier meal, toss in some protein. Cubed tofu is my go-to—just add it during the last few minutes of simmering so it soaks up all that miso goodness. For a meatier vibe, shredded chicken or thinly sliced beef work beautifully—just cook them separately first and stir them in at the end. And if you’re feeling extra indulgent? A soft-boiled egg on top is *chef’s kiss*.

Mushroom mix-ups

Shiitake mushrooms are my first love here, but honestly? Any mushroom works. Button mushrooms are super accessible and still delicious, while cremini mushrooms add a deeper, earthier flavor. For a wilder twist, try oyster mushrooms or maitake—their delicate, almost frilly texture is so fun in the broth. And if you’re feeling extra adventurous, mix and match! Just keep the total amount the same (about 1 cup sliced).

Veggie vibes

Got some veggies that need rescuing from the crisper? Toss them in! Baby spinach or bok choy are my favorites—they wilt beautifully in the hot broth. Thinly sliced carrots or daikon radish add a subtle sweetness and crunch. And if you’re a seaweed fan? A handful of wakame or kelp gives it that classic Japanese miso soup feel.

Noodle dreams

Want to turn this into a full-on meal? Add noodles! Soba noodles are my top pick—they cook fast and pair perfectly with the miso flavor. Ramen noodles are another winner—just cook them separately and add them to your bowl before ladling in the soup. And if you’re gluten-free? Rice noodles or zoodles work like a charm.

Spice it up

If you’re like me and love a little heat, this soup is begging for some spice. A drizzle of chili oil or a sprinkle of red pepper flakes adds a nice kick. Or, for a more complex heat, stir in a teaspoon of gochujang (Korean chili paste) with the miso. Just taste as you go—spice can sneak up on you!

The beauty of this soup is how forgiving it is. I’ve thrown in everything from leftover roasted veggies to a handful of frozen edamame, and it always turns out delicious. So don’t stress—just have fun with it and make it your own. Soup is love, after all!

Serving Suggestions

Okay, picture this: your miso mushroom soup is bubbling away, smelling like a cozy dream. Now, what to serve with it? Here’s my tried-and-true lineup of pairings—some classic, some unexpected—that’ll turn your soup into a full-on feast.

The Classic: Steamed Rice

I always keep a pot of rice going when I make this soup. A scoop of fluffy jasmine or short-grain rice at the bottom of your bowl soaks up that glorious broth like a flavor sponge. Pro tip: for extra fun, try brown rice or black rice—their nuttiness plays so nicely with the mushrooms.

The Crunch Factor: Side Salad

A simple cucumber salad with rice vinegar and sesame seeds is my go-to. The crisp, tangy contrast cuts through the soup’s richness perfectly. Or toss together some baby greens with a ginger dressing—it takes 2 minutes and makes the meal feel fancy.

The Ultimate Combo: Gyoza

Confession: I keep frozen dumplings on hand just for soup nights. Pan-fried vegetable or pork gyoza dunked in the broth? Absolute heaven. The crispy bottoms and savory filling turn your humble soup into a restaurant-worthy spread.

For Dippers: Toasted Bread or Nori

No rice? No problem! A slice of crusty sourdough or toasted baguette is perfect for sopping up every last drop. Or channel Japanese izakaya vibes with crispy nori sheets—just tear and dunk for an instant umami boost.

The Breakfast Twist (Trust Me)

Here’s my weird-but-wonderful secret: sometimes I crack a soft-boiled egg right into the hot soup for breakfast. The creamy yolk swirling into the broth? Next-level comfort. Add a sprinkle of furikake if you’re feeling extra.

Really though, this soup stands proud all on its own. I’ve happily slurped it straight from the mug while standing at the counter more times than I can count. But when you want to make it a meal, these pairings never disappoint. Now go forth and dip, dunk, and devour!

Storing and Reheating Miso Mushroom Soup

Okay, let’s talk leftovers—because let’s be real, sometimes you make this soup and suddenly realize you’ve cooked enough for a small army. (Or maybe that’s just me when I get overexcited about mushrooms.) Here’s how to keep it tasting fresh and fabulous for round two.

Fridge Storage: The 2-Day Rule

First things first: let the soup cool completely before storing. I’ve learned this the hard way—putting hot soup straight in the fridge makes everything else sweat, and nobody wants soggy cheese or warm milk. Pour it into an airtight container (I love glass jars because you can see the pretty layers), and it’ll keep for 2 days max. The miso and mushrooms hold up surprisingly well, but the scallions will lose their brightness—just toss fresh ones on when you reheat!

Reheating Like a Pro

Here’s my golden rule: gentle heat is key. Microwaving works in a pinch (stir every 30 seconds!), but I prefer the stovetop. Warm it over low heat, stirring occasionally until just steaming—don’t let it boil, or the miso will turn bitter. The soup thickens as it chills, so add a splash of water or broth to loosen it up. Taste and adjust with a tiny bit more soy sauce or sesame oil if needed.

The Freezer Question

Honestly? I don’t freeze this one. Miso behaves oddly when frozen—it can separate and get grainy—and the mushrooms turn rubbery. If you must freeze it, skip the scallions and add them fresh later. Thaw overnight in the fridge, then reheat gently with extra broth to revive the texture.

Pro tip: Store any uncooked scallions separately (wrap them in a damp paper towel in a baggie) to keep them crisp for garnishing later. And if your soup disappears before storage even becomes an issue? Welcome to the club—mine rarely lasts past lunchtime the next day!

Miso Mushroom Soup with Scallions Nutritional Info

Okay, let’s talk numbers—but first, a big ol’ disclaimer: these estimates can vary depending on your exact ingredients. Did you use low-sodium broth or full-salt miso? Added tofu or kept it simple? All those little choices tweak the stats. That said, here’s the general nutritional breakdown per serving (about one big, soul-warming bowl):

Calories: Around 120 – light enough for a snack, but pair it with rice or dumplings if you need more staying power.
Sodium: Roughly 800mg (thanks, miso and soy sauce!) – opt for low-sodium versions if you’re watching intake.
Protein: About 5g – mushrooms and miso pack a surprising punch! Boost it with tofu or chicken.
Fat: Only 4g (mostly from that glorious sesame oil) – and it’s the good kind of unsaturated fat.
Carbs: 15g – mostly from the natural sugars in mushrooms and miso, with 2g of fiber.

Now, here’s my chef’s secret: nutrition matters, but so does joy. This soup is packed with gut-friendly fermented miso, immune-boosting garlic and ginger, and antioxidant-rich mushrooms. Sometimes? That’s better than any number on a label. But if you’re tracking closely, just tweak ingredients—less miso, more mushrooms, etc.—to fit your needs. The soul-warming magic stays the same!

FAQs About Miso Mushroom Soup

Okay, let’s tackle those burning questions I get all the time about this soup—because trust me, after making it weekly for years, I’ve heard them all! Here’s the real-deal scoop to make your bowl perfect every time.

Can I use white miso instead of red?

Absolutely! White miso (shiro miso) is actually my go-to—it’s milder and slightly sweet, which lets the mushrooms shine. Red miso packs a deeper, saltier punch if that’s your vibe. Pro tip: start with less (maybe 2 tbsp instead of 3) and taste as you go—you can always add more!

How do I reduce the sodium in this soup?

Easy fixes: use low-sodium vegetable broth, cut the soy sauce in half (or swap for coconut aminos), and rinse canned mushrooms if using them. Also, add the miso at the very end—the longer it cooks, the saltier it tastes. A squeeze of lemon at the end balances flavors too!

My soup turned out too thin—help!

No sweat! Simmer it uncovered for 5 extra minutes to reduce. Or, my favorite trick: dissolve ½ tsp cornstarch in 1 tbsp cold water, then stir it in while simmering. For a natural thickener, toss in a handful of instant oats or blend ¼ cup of the soup and mix it back in. Boom—instant body!

Can I make this ahead for meal prep?

You bet—just leave out the scallions until serving. Store cooled soup in the fridge for up to 2 days (it thickens—that’s normal!). Reheat gently with a splash of water. Don’t freeze it though—miso gets weirdly grainy when frozen.

What’s the best mushroom substitute if I don’t have any?

Try thinly sliced zucchini (sauté just 2 minutes) or shredded cabbage for texture. For umami, add a spoonful of tomato paste with the garlic or toss in a dried shiitake while simmering (remove before eating). Not quite the same, but still delish in a pinch!
