Step-by-Step: Making Miso Udon Noodle Soup
-
Cook the noodles: Boil your udon according to package directions. Drain, rinse, and divide between two bowls.

-
Season: Mix in miso paste, soy sauce, and mirin. Bring to a gentle boil, then simmer 10–12 minutes. Taste and add salt if needed.

Tips for Perfecting Your Soup
-
Don’t boil the miso too hard. High heat can dull its delicate flavor, so let it simmer gently.
-
Use frozen udon if you can. They have that chewy, slurp-worthy texture you just don’t get from dried.
-
Nut butter tip: Peanut butter works in a pinch, but tahini or Asian sesame paste adds that authentic nutty depth.
-
Customize the mushrooms. If king oyster mushrooms aren’t at your store, cremini or portobello slices are just as tasty.
-
Spice it your way. A drizzle of chili oil adds heat, but sriracha or even a dash of cayenne works if that’s what’s in the pantry.
Think of this recipe as a framework—you can always swap and adjust to match what you’ve got on hand.
A Little Story from My Kitchen
This Miso Udon Noodle Soup with Teriyaki Mushrooms actually came about on a rainy night when my fridge was nearly bare. I had half a carton of soy milk, some miso paste hiding in the back of the fridge (you know, the one you bought for a single recipe six months ago), and a pack of frozen udon noodles. The mushrooms were a happy accident—leftovers from a stir-fry that I thought deserved better than slowly shriveling in the veggie drawer.
I tossed everything together, not expecting much, and my husband looked up from his bowl with wide eyes after the first slurp. “This tastes like restaurant ramen!” he said. And honestly? That’s been the running review ever since.
Now it’s our go-to comfort dinner, especially when I need something quick but still crave that “wow” factor. It’s proof that pantry staples and a little creativity can transform into something downright magical.
What to Serve with Miso Udon Noodle Soup
This soup is plenty satisfying on its own, but if you’re feeling extra, here are some ideas:
-
Crispy spring rolls for a crunchy side.
-
Steamed edamame sprinkled with sea salt—simple and protein-packed.
-
Asian-style cucumber salad with rice vinegar and sesame for a refreshing bite.
-
Kimchi or pickled veggies to add a tangy, spicy contrast.
And let’s be real—if you just want to curl up with the soup and a cozy blanket, that’s perfectly valid too. No rules in comfort food land!
How to Store Leftovers
Soup like this is almost better the next day because the flavors have more time to mingle.
-
Fridge: Store broth and noodles separately if possible. The noodles can get mushy if they sit too long in liquid. Both keep well for about 3 days.
-
Freezer: The broth freezes beautifully (up to 2 months), but skip freezing the noodles. Cook fresh ones when you reheat.
-
Reheat: Warm broth gently on the stove—don’t blast it on high heat or the miso can lose flavor. Cook new noodles and combine before serving.
Pro tip: Store extra teriyaki mushrooms separately too. They reheat like a dream and keep their sticky-sweet glaze intact.
FAQs
Can I make this without sake or mirin?
Absolutely! Just add a tiny splash of rice vinegar with an extra pinch of sugar for balance.
Can I substitute the nut butter?
Yes—you can use tahini, cashew butter, or skip it altogether for a lighter broth.
What kind of miso should I use?
White miso is mild and slightly sweet, making it perfect for soups. Red miso is stronger and saltier, so use less if that’s what you have.
Is this a vegan udon soup?
Yes, as long as you use vegan butter (or sesame oil) and plant-based broth.
Can I add protein to this soup?
Definitely! Tofu cubes, seitan strips, or even edamame are great additions if you want extra protein.
