Ingredients You’ll Need

Broth base

• Neutral oil
  Canola, avocado, or light olive oil all work. Use sesame oil only as a finishing drizzle, not for sautéing, since it burns fast.

• Aromatics

  • 1 medium yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 to 2 tablespoons fresh ginger, minced or grated
    Squeeze-tube ginger and garlic work in a pinch, though fresh gives better flavor.

• Vegetables for the soup

  • 2 medium carrots, thinly sliced into coins or matchsticks
  • 1 small leek or 3 green onions, sliced
  • 1 to 2 cups baby spinach or chopped bok choy
  • Optional: 1 small zucchini or a handful of snap peas for extra crunch

• Broth

  • 6 cups low sodium vegetable broth or chicken broth
    I like using low sodium Better Than Bouillon paste since it keeps in the fridge and tastes rich.

• Miso paste

  • 3 to 4 tablespoons white or yellow miso paste
    White miso tastes milder and slightly sweet. Red miso tastes stronger and saltier, so start with less if you use it.

• Soy sauce or tamari

  • 2 to 3 tablespoons low sodium soy sauce or tamari for gluten free
    Use a Japanese style soy sauce like Kikkoman or Yamasa if you can.

• Rice vinegar

  • 1 to 2 teaspoons rice vinegar for brightness
    Seasoned rice vinegar already contains sugar and salt, so taste before adding more seasoning.

• Optional flavor boosters

  • 1 teaspoon toasted sesame oil
  • 1 teaspoon chili crisp or a pinch of red pepper flakes
  • 1 teaspoon mirin or a pinch of sugar if you like a slightly sweeter broth

Udon noodles

• Udon noodles
  • 12 to 16 ounces udon noodles
    You can use:
  • Frozen udon: best chewy texture and my top choice
  • Vacuum packed shelf stable udon: easy pantry option
  • Dried udon: works fine, just cook a bit longer and do not overcook

Cook noodles separately if you plan to store leftovers, so they stay bouncy and do not soak up all the broth.

Teriyaki mushrooms

• Mushrooms

  • 12 ounces to 1 pound mushrooms, sliced
    Shiitake, cremini, or a mix of shiitake and oyster mushrooms taste amazing. Remove shiitake stems since they stay tough.

• Teriyaki sauce ingredients

  • 3 tablespoons soy sauce or tamari
  • 1 tablespoon brown sugar, maple syrup, or honey
  • 1 tablespoon mirin or rice vinegar
  • 1 teaspoon grated ginger
  • 1 clove garlic, minced
  • 2 to 3 tablespoons water
  • 1 teaspoon cornstarch

You can use a bottled teriyaki sauce if you want a shortcut. I still like to add a little fresh ginger and garlic to wake it up.

Toppings

• Sliced green onions
• Toasted sesame seeds
• Nori strips or furikake
• Chili oil or chili crisp
• Soft boiled egg halves, if you eat eggs
• Cubed tofu or shredded rotisserie chicken for extra protein

Equipment

• Large stock pot or Dutch oven
• Medium skillet or sauté pan for the teriyaki mushrooms
• Small bowl for mixing teriyaki sauce
• Tongs or chopsticks for handling noodles
• Ladle for serving

Tips & Tricks

• Use frozen udon for the best chewy texture and quick cooking.
• Sauté the mushrooms in a single layer so they brown instead of steaming.
• Add miso at the end off the heat so it stays smooth and keeps its flavor.
• Mix miso with a ladle of hot broth in a small bowl, then stir that mixture into the pot to avoid clumps.
• Keep the broth at a gentle simmer, not a rolling boil, so the flavors stay clean and the veggies keep some texture.
• Cook noodles separately and add them to bowls before ladling broth if you plan to store leftovers.
• Taste the broth before adding extra salt, since miso and soy sauce already bring plenty of seasoning.
• Slice veggies thin so they cook quickly and evenly.
• Use a nonstick or well seasoned pan for the teriyaki mushrooms so the glaze sticks to the mushrooms, not the pan.
• If the teriyaki sauce thickens too much, splash in a little water and stir until it loosens.

How to Make Miso Udon Noodle Soup with Teriyaki Mushrooms

Step 1: Sauté veggies and aromatics

Heat 1 to 2 tablespoons oil in a large stock pot or Dutch oven over medium heat. Add sliced onion and carrots and cook until they soften and turn slightly golden, about 7 to 8 minutes, stirring occasionally. Stir in garlic and ginger and cook about 1 to 2 minutes, until they smell fragrant and cozy.

Step 2: Build the miso udon broth

Pour in the broth and bring it to a gentle simmer. Add soy sauce, a small splash of rice vinegar, and any optional flavor boosters like chili crisp or a drizzle of toasted sesame oil. Toss in the sliced leek or green onions and any firm veggies like snap peas or zucchini, then simmer 5 to 7 minutes until the veggies turn tender but not mushy.

Scoop a ladle of hot broth into a small bowl. Whisk in the miso paste until it dissolves completely and looks smooth. Turn the heat to low, then stir the miso mixture back into the pot and keep the soup just below a simmer so it stays hot without boiling.

Step 3: Cook the udon noodles

While the broth simmers, bring a separate pot of water to a boil. Add the udon noodles and cook according to package directions until they turn just tender and springy. Rinse briefly under hot water to loosen them, then drain well.

If you plan to store leftovers, drizzle the noodles with a tiny bit of oil and toss so they do not stick. Keep them in a separate container from the broth.

Step 4: Make the teriyaki mushrooms

In a small bowl, whisk together soy sauce, brown sugar or maple syrup, mirin or rice vinegar, grated ginger, minced garlic, water, and cornstarch until smooth. Heat a tablespoon of oil in a skillet over medium high heat. Add sliced mushrooms in a single layer and cook without stirring for 3 to 4 minutes so they brown on one side.

Stir and continue cooking another 3 to 4 minutes until they release their moisture and start to caramelize around the edges. Pour in the teriyaki mixture and stir. The sauce will bubble and thicken in 1 to 2 minutes and coat the mushrooms in a shiny glaze.

Step 5: Assemble the bowls

Place a portion of udon noodles into each bowl. Ladle hot miso broth and veggies over the noodles. Top with a generous spoonful of teriyaki mushrooms.

Finish with sliced green onions, sesame seeds, and any extras like a soft boiled egg, tofu cubes, or nori strips. Serve right away while everything tastes hot and slurp worthy.

What to Serve with Miso Udon Noodle Soup with Teriyaki Mushrooms

This Miso Udon Noodle Soup with Teriyaki Mushrooms already eats like a full meal, but a few simple sides make it feel special.
