Ingredients You’ll Need

Here is everything you need to make this Harusame Japanese Glass Noodle Soup Recipe at home. I include some pantry shortcuts and swaps so you can use what you already have.

Noodles

3 to 4 ounces dried harusame noodles (potato starch or mung bean glass noodles)
- Use any clear glass noodle labeled harusame, mung bean vermicelli, or cellophane noodles.
- Avoid rice vermicelli here, since it turns softer and loses that signature chew.

Broth base

4 cups low sodium chicken broth
- Use vegetable broth for a vegetarian or vegan version.
1 cup water
1 tablespoon soy sauce
- Use tamari or coconut aminos if you avoid gluten.
1 tablespoon mirin
- If you do not keep mirin, use 1 tablespoon water plus 1 teaspoon sugar.
1 teaspoon toasted sesame oil
1 to 1½ teaspoons kosher salt, to taste
¼ teaspoon ground white pepper or black pepper

Aromatics and vegetables

1 tablespoon neutral oil (canola, avocado, or light olive oil)
2 cloves garlic, minced
1 teaspoon grated fresh ginger
2 green onions, thinly sliced, white and green parts separated
1 small carrot, cut into matchsticks or thin half moons
1 cup napa cabbage, thinly sliced
- Use regular green cabbage if that is what you have.
½ cup sliced shiitake mushrooms
- Use cremini or button mushrooms if shiitake are not available.
½ cup baby spinach or bok choy leaves, roughly chopped

Protein options (pick one or mix)

4 ounces thinly sliced chicken thigh or breast
or 4 ounces thinly sliced pork loin
or 4 ounces peeled shrimp
or ½ block (7 to 8 ounces) firm tofu, cubed
or 1 egg, lightly beaten, for egg drop style ribbons

Toppings and finishing touches

Extra sliced green onion tops
Toasted sesame seeds
Chili oil or shichimi togarashi for heat
A squeeze of lime or lemon if you like a brighter finish

Equipment list

Medium pot or small Dutch oven
Cutting board and sharp knife
Small bowl for soaking noodles
Measuring spoons and cups
Ladle and tongs or chopsticks

Tips & Tricks

Soak the harusame noodles in hot tap water for 10 to 15 minutes so they soften before they hit the pot and cook evenly.
Slice proteins and veggies thin so they cook quickly and stay tender in the broth.
Taste the broth before you add the noodles and adjust salt, soy sauce, or mirin so the flavor feels slightly stronger than you want in the final bowl.
Add spinach or other tender greens at the very end so they stay bright and do not turn mushy.
Cook shrimp or thin meat directly in the simmering broth and pull a piece out to check doneness so you avoid overcooking.
Use tofu or egg if you want a lighter protein that still adds body and comfort.
Keep the noodles slightly undercooked if you plan to store leftovers, since they continue to soften in the broth.
Store noodles and broth separately when possible so the texture stays springy instead of soggy.

How to Make Harusame Japanese Glass Noodle Soup Recipe

Step 1: Soak the noodles

Place the dried harusame noodles in a heatproof bowl.
Cover them with very hot tap water and let them sit for 10 to 15 minutes until they turn flexible and mostly clear.
Drain them well and set them aside while you prepare the rest of the soup.

Step 2: Prep the vegetables and aromatics

Slice the green onions, keeping white parts and green tops separate.
Cut the carrot, cabbage, mushrooms, and any other veggies you use into thin pieces so they cook quickly.
Mince the garlic and grate the ginger.

Step 3: Sauté aromatics

Heat the neutral oil in your pot over medium heat.
Add the garlic, ginger, and the white parts of the green onions.
Stir and cook for about 30 seconds to 1 minute until they smell fragrant and look slightly softened, and keep the heat moderate so they do not burn.

Step 4: Build the broth

Pour in the chicken broth and water.
Stir in soy sauce, mirin, sesame oil, salt, and pepper.
Bring the mixture to a gentle boil, then lower to a steady simmer so the flavors come together.

Step 5: Cook the vegetables

Add the carrot, cabbage, and mushrooms to the simmering broth.
Cook for 3 to 4 minutes until the veggies turn just tender but still hold some bite.
Add the spinach or bok choy and cook for 1 more minute so the greens wilt.

Step 6: Add the protein

Slide in your thinly sliced chicken, pork, shrimp, or tofu.
Stir gently and cook until the protein turns opaque and cooked through, usually 2 to 4 minutes depending on thickness.
If you use egg, drizzle the beaten egg slowly into the hot broth while you stir in circles so soft ribbons form.

Step 7: Add the harusame noodles

Add the soaked and drained harusame noodles to the pot.
Use tongs or chopsticks to separate the strands and mix them through the broth.
Simmer for 1 to 2 minutes until the noodles turn fully clear and tender but still slightly chewy.

Step 8: Taste and adjust

Taste the broth and adjust with more salt, soy sauce, or a splash of water if the flavor feels too strong.
Add a pinch more white or black pepper if you like a bit more warmth.
Turn off the heat once everything tastes balanced.

Step 9: Serve

Ladle the Harusame Japanese Glass Noodle Soup Recipe into warm bowls, making sure each bowl gets a good mix of noodles, veggies, and protein.
Top with green onion tops, toasted sesame seeds, and a drizzle of chili oil if you enjoy some heat.
Serve right away while the noodles stay bouncy and the broth tastes hot and comforting.

What to Serve with Harusame Japanese Glass Noodle Soup Recipe

This Harusame Japanese Glass Noodle Soup Recipe pairs nicely with simple sides like steamed edamame, cucumber salad, or a small bowl of rice. I like to add a side of pan-fried gyoza or vegetable dumplings when I want a more filling meal. You can also serve it with a crisp cabbage slaw or a quick seaweed salad for extra veggies. A glass of iced green tea or hot barley tea rounds out the meal without overpowering the delicate broth.

Storage Options

Store leftover soup in the fridge for up to 3 days, and cool it to room temperature before you cover and chill it.
Keep noodles and broth in separate containers if you can, and add noodles to the hot broth right before you eat.
Freeze the broth with veggies and protein (without noodles) for up to 2 months, and add freshly soaked noodles when you reheat.
Reheat on the stovetop over medium heat until hot but not boiling hard, and add a splash of water if the broth tastes too concentrated.
