Ingredients You Need
Glass noodles and base
-
Harusame noodles (Japanese glass noodles)
- Look for packages labeled “harusame” or “potato starch noodles” in Asian markets.
- You can also use mung bean glass noodles if you cannot find Japanese brands.
- I like clear, thin noodles from brands like Hikari or Shirakiku because they stay bouncy.
-
Neutral oil
- Use canola, avocado, grapeseed, or light olive oil.
- Sesame oil burns quickly, so keep it for finishing, not sautéing.
Aromatics and veggies
-
Yellow onion, thinly sliced
- White onion also works.
- Pre-sliced frozen onions save time and still taste great in soup.
-
Carrots, matchsticks or thin rounds
- Baby carrots sliced into coins work if that is what you have.
- Keep pieces thin so they soften quickly.
-
Garlic, minced
- Use fresh cloves or frozen garlic cubes.
- Garlic powder works in a pinch; use about half the amount.
-
Fresh ginger, minced or grated
- Tube ginger (like Gourmet Garden) works well and saves time.
- Powdered ginger changes the flavor, so use it only if you must.
-
Green onions (scallions)
- Use white and light green parts in the soup and save dark green tops for garnish.
- Chives work if you lack scallions, but use a lighter hand.
-
Mushrooms, sliced
- Shiitake, shimeji, or cremini all taste great.
- Dried shiitake add deep flavor; soak them in hot water and use the soaking liquid in the broth.
-
Leafy greens
- Napa cabbage, spinach, bok choy, or baby kale all fit nicely.
- Use what you have and slice it thin so it wilts quickly.
Broth and seasoning
-
Low sodium chicken or vegetable broth
- Use a good boxed broth or homemade stock if you have it.
- Low sodium broth gives you room to season with soy sauce without oversalting.
-
Water
- Stretch the broth with some water to keep the flavor gentle.
- If you use a strong dashi, you can skip water.
-
Dashi powder or dashi stock
- Instant dashi granules make this recipe weeknight friendly.
- Use kombu and dried shiitake if you prefer a vegetarian dashi.
-
Soy sauce
- Use regular or light soy sauce, not dark.
- Tamari or coconut aminos work if you need a gluten free option.
-
Mirin
- Adds a subtle sweetness and depth.
- Mix a little sugar with rice vinegar if you do not have mirin.
-
Salt and ground white or black pepper
- Season at the end to taste.
- White pepper gives a gentle heat that suits this soup.
-
Toasted sesame oil
- Drizzle at the end for aroma.
- A tiny amount goes a long way.
Optional protein add ins
Pick one or mix a couple:
-
Thinly sliced chicken thigh or breast
- Slice it very thin so it cooks quickly in the broth.
- Season lightly with salt before it hits the pot.
-
Firm or extra firm tofu, cubed
- Press it briefly to remove excess water.
- Pan sear cubes in a little oil if you want a chewier texture.
-
Shrimp, peeled and deveined
- Use small or medium shrimp so they cook fast.
- Frozen shrimp work; thaw them under cold water.
-
Eggs
- Crack eggs into the hot broth and swirl for an egg drop effect.
- Or soft boil eggs separately and serve halves on top.
Toppings and finishing touches
- Thinly sliced green onion tops
- Toasted sesame seeds
- Chili oil or shichimi togarashi for heat
- Nori strips or furikake for extra umami
- Lime wedges if you like a bright finish
Equipment list
- Large stock pot or Dutch oven
- Medium bowl for soaking noodles
- Cutting board and sharp knife
- Ladle and tongs or chopsticks
- Measuring cups and spoons
Tips & Mistakes
- Soak glass noodles in warm water, not boiling water, so they soften without turning mushy.
- Add noodles near the end of cooking, since they soften quickly and turn soft if they sit too long.
- Slice veggies thin so they cook evenly and stay tender, not crunchy or overcooked.
- Taste the broth before adding more soy sauce, since dashi and broth already contain salt.
- Keep the soup at a gentle simmer, not a hard boil, so the broth stays clear and clean.
- Add leafy greens in the last couple of minutes so they stay bright and tender.
- Cook shrimp or thin chicken directly in the broth, but do not walk away, since they cook fast.
- Store noodles and broth separately when possible, so the noodles do not soak up all the liquid.
- Reheat on the stove over low heat and add a splash of water or broth if the soup thickens.
- Garnish bowls individually so leftovers reheat without wilted or soggy toppings.
How to Make Harusame Japanese Glass Noodle Soup Recipe
Step 1: Soak the glass noodles
Place the harusame noodles in a medium bowl.
Cover with warm water and let them soak 10 to 15 minutes until pliable but still slightly firm.
Drain well and set aside while you start the soup.
Step 2: Sauté veggies and aromatics
Heat oil in a large stock pot or Dutch oven over medium heat.
Once hot, add onions and carrots; cook until soft, about 8 minutes.
Stir in garlic, ginger, and the white parts of the green onions; cook 2 minutes, until aromatic.
Season lightly with salt and a pinch of pepper.
Step 3: Build the broth
Add mushrooms to the pot and cook 3 to 4 minutes until they soften and give off some moisture.
Pour in broth and water, then stir in dashi powder, soy sauce, and mirin.
Bring the mixture to a gentle simmer over medium heat.
Taste and adjust seasoning with more soy sauce or salt if needed.
Step 4: Add protein and greens
If you use chicken or shrimp, add it to the simmering broth and cook until it turns opaque and cooks through.
If you use tofu, gently slide cubes into the pot and simmer a few minutes so they soak up flavor.
Add sliced greens and cook 1 to 2 minutes until they wilt and turn tender.
Keep the heat at a gentle simmer so everything cooks evenly.
Step 5: Finish with noodles
Add the soaked glass noodles to the pot.
Simmer 2 to 3 minutes until the noodles turn clear and tender but still slightly chewy.
Turn off the heat and drizzle in a little toasted sesame oil.
Give everything a gentle stir so noodles, veggies, and protein distribute evenly.
Step 6: Garnish and serve
Ladle the soup into warm bowls, making sure each bowl gets a good mix of noodles, veggies, and broth.
Top with sliced green onion tops, toasted sesame seeds, and chili oil or shichimi togarashi if you like heat.
Add nori strips or furikake for extra umami.
Serve right away while the noodles stay bouncy and the broth tastes hot and fragrant.
Variations I've Tried
I often swap the chicken broth for a full kombu and shiitake dashi to keep the soup vegetarian and extra savory.
Sometimes I add a spoonful of miso paste at the end, off the heat, for a creamier, richer broth.
On busy nights, I toss in frozen mixed veggies and frozen shrimp and still get a satisfying bowl.
I also like a spicy version with extra chili oil, more ginger, and a squeeze of lime for a brighter, punchier finish.
How to Serve Harusame Japanese Glass Noodle Soup Recipe
Serve Harusame Japanese Glass Noodle Soup steaming hot in deep bowls so the noodles stay submerged and silky. Add extra toppings at the table, like more scallions, chili oil, or sesame seeds, so everyone can customize. Pair it with simple sides like steamed rice, edamame, or a crisp cucumber salad. I also like it with hot green tea or iced barley tea when I want a light, soothing meal.
How to store
- Fridge, broth and noodles separate: Store broth with veggies and protein in an airtight container for up to 4 days, and keep cooked noodles in a separate container for 2 to 3 days.
- Fridge, combined: If you already mixed noodles and broth, store up to 2 days and expect the noodles to soak up some liquid.
- Freezer: Freeze broth with veggies and protein (no noodles) for up to 2 months, then thaw in the fridge overnight before reheating and adding fresh soaked noodles.
- Reheating on stove: Warm soup in a pot over low to medium heat until hot, then add noodles and cook just until heated through and tender.
- Reheating in microwave: Heat in short bursts, stirring between each, and add a splash of water or broth if the soup thickens.
