Miso Udon Noodle Soup with Teriyaki Mushrooms

Miso Udon Noodle Soup with Teriyaki Mushrooms tastes savory, slightly sweet, and deeply comforting, like a cozy hug in a bowl with a little umami mic drop at the end. It works perfectly for busy weeknights or lazy weekends, and you can get it on the table in about 35 minutes. I started making this on cold Chicago nights when I wanted takeout vibes without changing out of sweatpants.

Why Make This Miso Udon Noodle Soup with Teriyaki Mushrooms at Home

You control the salt, the sweetness, and the richness, which means you get restaurant-level flavor without the heavy, salty after-effect. Homemade miso udon noodle soup with teriyaki mushrooms also lets you pack in more veggies and protein than most takeout versions.

You also save money and avoid mystery ingredients. Once you keep miso paste, soy sauce, and frozen udon in your kitchen, this soup turns into a low-effort, high-reward regular in your dinner rotation.

Ingredients You Need

Broth base

• Low-sodium vegetable broth or chicken broth

  • Use low-sodium so you control the salt with miso and soy sauce.
  • I like Better Than Bouillon vegetable base for a pantry shortcut.

• Water

  • Helps balance the broth so it does not taste too salty or intense.

• White or yellow miso paste

  • White miso tastes mild and slightly sweet, perfect for soup.
  • Yellow miso works too, but avoid very dark red miso here since it can overpower the delicate udon flavor.

• Soy sauce or tamari

  • Use tamari for a gluten free option.
  • I prefer low-sodium Kikkoman or San-J.

• Mirin

  • Adds gentle sweetness and depth.
  • If you do not have mirin, use a mix of rice vinegar and a pinch of sugar.

• Toasted sesame oil

  • Adds nutty aroma at the end.
  • Use it as a finishing oil, not a cooking oil.

• Garlic, minced

  • Fresh garlic gives the broth a punchy base.
  • Garlic paste from a tube works in a pinch.

• Fresh ginger, grated or minced

  • Gives warmth and brightness.
  • Frozen ginger cubes or ginger paste both work as shortcuts.

Noodles and mushrooms

• Udon noodles

  • Frozen udon gives the best chewy texture and cooks quickly.
  • Shelf-stable udon works too, just follow package timing and rinse lightly to remove extra starch.

• Mushrooms

  • Use shiitake, cremini, or baby bella mushrooms for the teriyaki topping.
  • A mix of shiitake and oyster mushrooms tastes fantastic if you want extra texture.

Teriyaki mushroom glaze

• Soy sauce or tamari
• Mirin
• Brown sugar or maple syrup
  • Brown sugar gives a deeper caramel flavor, maple syrup adds a lighter sweetness.
• Rice vinegar
  • Balances the sweetness so the mushrooms do not taste cloying.
• Cornstarch
  • Thickens the glaze so it clings to the mushrooms.
• Neutral oil such as avocado, canola, or grapeseed
  • Helps the mushrooms brown instead of steam.

Veggies and toppings

• Green onions (scallions), thinly sliced

  • Use both white and green parts for flavor and color.

• Baby spinach, bok choy, or napa cabbage

  • Toss into the hot broth to wilt.
  • Baby spinach works as the easiest option.

• Carrots, julienned or thinly sliced

  • Add sweetness and crunch.

• Tofu or protein of choice

  • Silken tofu gives a soft, custardy texture.
  • Firm tofu cubes, shredded rotisserie chicken, or leftover roasted chicken all work well.

• Toasted sesame seeds

  • Add crunch and a nutty finish.

• Chili oil or shichimi togarashi (Japanese chili seasoning)

  • Optional, for a little heat.

Equipment list

• Medium pot or Dutch oven for the broth
• Large skillet for the teriyaki mushrooms
• Small bowl for mixing the teriyaki glaze
• Ladle and tongs or chopsticks
• Fine mesh strainer (optional, for miso)
• Cutting board and sharp knife

Tips & Mistakes

• Use low-sodium broth so the miso and soy sauce do not push the soup into salt overload.
• Whisk miso paste in a small bowl with warm broth, then add it to the pot so it dissolves smoothly and does not clump.
• Keep the broth below a boil after you add miso, since high heat dulls the flavor and can make it taste flat.
• Brown the mushrooms in a single layer and resist stirring too often so they caramelize instead of steaming.
• Add the teriyaki glaze only after the mushrooms brown, or they will simmer in sauce and turn soggy.
• Cook udon noodles just until tender and springy, since overcooked udon turns mushy and loses that signature chew.
• Add delicate greens like spinach at the very end so they wilt gently and stay bright.
• Taste the broth before serving and adjust with more miso for depth, soy sauce for salt, or a splash of mirin for sweetness.
• Serve chili oil or shichimi on the side so spice lovers can go wild and everyone else stays comfortable.
• Store noodles and broth separately when possible so the udon does not soak up all the liquid overnight.

How to Make Miso Udon Noodle Soup with Teriyaki Mushrooms

Step 1: Prep ingredients

Slice the mushrooms, green onions, and any veggies you plan to use. Mince the garlic and grate the ginger. If you use tofu, cut it into cubes and pat it dry with a clean towel or paper towel.

Keep the miso paste, soy sauce, mirin, and sesame oil nearby. This setup makes the cooking flow smoothly and keeps you from scrambling while the mushrooms brown.

Step 2: Start the broth

Set a medium pot over medium heat and add a drizzle of neutral oil. Add the garlic and ginger and sauté for about 1 minute until fragrant, stirring so they do not burn. Pour in the vegetable or chicken broth and water.

Add a splash of soy sauce and a bit of mirin. Bring the broth to a gentle simmer, not a rolling boil. Let it bubble lightly while you cook the mushrooms so the flavors meld.

Step 3: Make the teriyaki mushroom glaze

In a small bowl, whisk together soy sauce, mirin, brown sugar or maple syrup, rice vinegar, and a small splash of water. In another tiny bowl, stir cornstarch with a spoonful of water to make a smooth slurry. Keep both bowls next to the stove.

Taste the glaze mixture and adjust the sweetness or salt to your liking. You want a balanced mix that tastes slightly salty, slightly sweet, and tangy.

Step 4: Cook the teriyaki mushrooms

Heat a large skillet over medium high heat and add a tablespoon of neutral oil. Add the sliced mushrooms in a single layer and let them sit for 2 to 3 minutes so they brown on one side. Stir and continue to cook until they release their moisture and turn golden around the edges.

Pour the soy sauce and mirin mixture over the mushrooms and stir. Bring it to a simmer, then drizzle in the cornstarch slurry while you stir. Cook for 1 to 2 minutes until the sauce thickens and coats the mushrooms in a glossy glaze, then turn off the heat.

Step 5: Finish the miso broth

Ladle a small cup of hot broth from the pot into a bowl. Add the miso paste to that bowl and whisk until smooth and creamy. Pour the miso mixture back into the pot and stir well.

Keep the heat on low so the broth stays hot but does not boil. Taste and adjust with more miso, soy sauce, or mirin if needed. Add a tiny drizzle of toasted sesame oil for aroma.

Step 6: Cook the udon noodles

Bring a separate pot of water to a boil. Add the udon noodles and cook according to package directions, usually 2 to 3 minutes for frozen udon or slightly longer for shelf-stable. Stir gently to separate the strands.

When the noodles turn tender and chewy, drain them. Rinse briefly under hot water if they feel very starchy, then shake off excess water. You can also add the noodles directly to the broth if you plan to serve all portions right away.

Step 7: Add veggies and protein

Add carrots and any thicker veggies like bok choy stems to the miso broth and simmer for 2 to 3 minutes until just tender. Add tofu or cooked chicken and let it warm through. Stir in baby spinach or bok choy leaves and cook for about 30 seconds until they wilt.

Turn off the heat. The veggies should stay bright and slightly crisp, not limp. Taste the broth one more time and adjust seasoning.

Step 8: Assemble the bowls

Divide the cooked udon noodles among serving bowls. Ladle the hot miso broth and veggies over the noodles. Top each bowl with a generous spoonful of teriyaki mushrooms.

Sprinkle with sliced green onions and toasted sesame seeds. Add a small drizzle of chili oil or a pinch of shichimi togarashi if you like heat. Serve right away while the noodles stay bouncy and the broth steams.

Variations I've Tried

I swap in soba noodles when I want a nuttier flavor and a slightly lighter feel, just cook them separately and rinse well. I also use firm tofu that I pan sear until golden, then add the teriyaki glaze to the tofu instead of the mushrooms for a protein-forward version.

Sometimes I add corn kernels and edamame to turn the miso udon noodle soup into a more filling one-bowl meal. On very cold nights, I stir in a spoonful of butter at the end, which sounds odd but gives the broth a rich, silky finish that tastes incredibly cozy.

How to Serve Miso Udon Noodle Soup with Teriyaki Mushrooms

Serve miso udon noodle soup with teriyaki mushrooms piping hot in deep bowls so the broth stays warm and the noodles stay tender. Add extra toppings on the table like more green onions, chili oil, sesame seeds, and a little extra soy sauce so everyone can customize. Pair it with a simple side like cucumber salad, steamed edamame, or roasted broccoli. This soup also works well as a main course for lunch with some sliced fruit on the side for a fresh finish.

How to store

• Fridge, broth and toppings: Store the miso broth, veggies, and teriyaki mushrooms together in an airtight container in the fridge for up to 3 days.
• Fridge, noodles: Store cooked udon noodles in a separate container with a tiny splash of oil to prevent sticking, also up to 3 days.
• Freezer: Freeze the broth and mushrooms (without noodles) for up to 2 months, then thaw in the fridge overnight before reheating.
• Reheating: Reheat the broth gently on the stove over medium heat until hot but not boiling, then add the noodles to warm through for 1 to 2 minutes so they stay chewy and not mushy.
