What Is Japanese Noodles Soup?

Japanese Noodle Soup is a cherished culinary cornerstone of Japan, featuring a rich, umami broth made from Kombu (kelp) and Bonito (fish) flakes. The soup is the canvas for various noodles, most commonly Udon, Soba, or Ramen, each with unique textures and flavors. 

Complemented with fresh vegetables and protein like chicken, beef, tofu, or seafood and garnished with scallions or Nori (seaweed), this dish symbolizes Japan’s tradition, simplicity, and respect for ingredient integrity.

Can You Vary The Japanese Noodles Soup With Other Ingredients? 

Japanese Noodle Soup is highly adaptable. Here are some ways to cater to various dietary needs:

  • Keto: Use Shirataki noodles, made from Konjac flour, that are virtually carb-free. Include plenty of low-carb vegetables like bok choy, mushrooms and protein such as chicken or tofu.
  • Paleo: Replace traditional noodles with spiralized vegetables like zucchini or sweet potato. Use coconut aminos instead of soy sauce and stick to Paleo-friendly proteins like chicken, beef, or seafood.
  • Gluten-Free: Opt for 100% buckwheat Soba noodles, which are naturally gluten-free, or try rice noodles. Ensure your soy sauce is gluten-free, as regular versions often contain wheat.
  • Whole30: Similar to Paleo modifications, use spiralized veggies instead of noodles. Replace soy sauce with coconut aminos, and use compliant broths and proteins.
  • Vegetarian/Vegan: Replace the traditional Dashi broth with a flavorful vegetable or Kombu-based Dashi. Substitute meat with tofu or tempeh, and ensure all other add-ins are plant-based.

Recipe Directions

  • Begin by preparing a flavorful broth infused with aromatic ingredients and umami-rich flavors.
  • Sauté a colorful medley of vegetables, such as thinly sliced carrots, snow peas, and napa cabbage, to enhance both taste and nutrition.
  • Cook the noodles of your choice until tender, whether udon, rice, or shirataki, ensuring a satisfying texture in every bite.
  • Assemble the soup by combining the prepared broth, sautéed vegetables, and cooked noodles, allowing the flavors to meld together in a simmering harmony.
  • Finally, serve the steaming bowl of Japanese Noodle Soup with your choice of garnishes, such as a drizzle of sesame oil or a sprinkle of sesame seeds, to add a touch of visual appeal and additional depth of flavor.

Variations, Add-Ons And Toppings 

Japanese Noodle Soup is highly versatile and allows numerous variations, add-ons, and toppings. Here are a few ideas:


  • Miso Ramen: Add a spoonful of Miso paste to the broth for a distinct, rich flavor. This pairs well with pork and corn toppings.
  • Shoyu Ramen: Make a soy sauce-based broth for a more savory, umami-rich soup. This often pairs well with marinated bamboo shoots (Menma) and Naruto (fish cake).
  • Tonkotsu Ramen: This is a creamier, richer version made with pork bone broth. It’s often topped with Chashu pork and pickled ginger.
  • Curry Udon: Add Japanese curry powder or paste to the broth to make a warming, comforting Curry Udon soup.


  • Proteins: Chicken, beef, tofu, and a variety of seafood like shrimp or clams can all be great additions to the soup.
  • Vegetables: Try different vegetables like bell peppers, bean sprouts, kale, or broccoli to add more nutrients and textures to your soup.


  • Spices: Add heat with chili oil, red pepper flakes, or Shichimi Togarashi (a seven-spice blend).Pickled Ginger or Radish: These add a refreshing, tangy note to balance the rich soup.
  • Sesame Seeds or Green Onions: These are simple but add a nice visual touch and a bit of texture.
  • Nori (Seaweed) or Wakame: These add a subtle oceanic flavor.

Can I Make Soup In A Slow Cooker Or Instant Pot?

A slow cooker and an Instant Pot can be excellent tools for preparing Japanese Noodle Soup.

Slow Cooker

  • This method is great for drawing out the flavors in the broth. Add your Kombu, Bonito flakes, and water, then let it simmer for a few hours.
    Once your Dashi broth is ready, strain it and add it back to the slow cooker with your proteins and vegetables, cooking until they’re tender. 
  • Cook noodles separately and add them before serving to prevent them from becoming overly soft. This method is great for a low-effort, deeply flavorful soup.

Instant Pot

  • Use the sauté function to make your Dashi broth (remember to strain), then add your proteins and firmer vegetables, using the pressure cook function to cook them quickly. 
  • Like the slow cooker method, cook your noodles separately and add them to the soup when ready to serve. The Instant Pot can significantly speed up cooking while delivering a flavorful soup.

Can I Use Store Broth, Or Should I Make My Own?

Both options are valid and depend on your available time, cooking skills, and personal preferences.

Making your own Dashi broth from scratch allows more control over the flavor profile and authenticity. Traditional Dashi is made from Kombu (kelp) and Bonito flakes, which give a depth of flavor hard to replicate with store-bought options.

However, storing broth can be convenient, especially in a rush. Pre-made Dashi broths are available in many stores or online, designed to offer the umami flavor typical of Japanese soups.

If you cannot find Dashi broth, a mild chicken or vegetable broth could be a substitute, though the flavor will be different. In this case, adding a dash of soy sauce or miso paste can help add some depth.

How To Serve ?

Serving Japanese Noodle Soup is all about timing and presentation. Here are some tips for serving it in the best way:

  • Timing: Noodles should be added to the soup before serving to avoid becoming too soft or overcooked. Similarly, delicate vegetables or garnishes should be added last to maintain their freshness and crunch.
  • Bowls: Japanese Noodle Soup is typically served in large, deep bowls to accommodate the broth, noodles, and various toppings.
  • Presentation: Arrange your toppings neatly on top of the broth, creating an appealing variety of colors and textures. This could mean placing slices of meat on one side, chopped scallions on another, a halved boiled egg in the middle, etc.
  • Utensils: Provide chopsticks for the solid ingredients and a large Asian-style soup spoon for the broth. If chopsticks are not preferred, a fork can be used for the noodles.
  • Accompaniments: Depending on the meal, you could serve the soup alongside other Japanese dishes like sushi, tempura, or a simple side salad. A glass of Sake or Japanese beer could also complement the meal.

Perfect Side Dishes

  • Gyoza (Japanese Dumplings): These pan-fried dumplings filled with meat and vegetables make a great side dish and can be dipped in a soy-vinegar sauce.
  • Edamame: Steamed and lightly salted edamame (young soybeans) are a simple and healthy side that can be eaten with your fingers.
  • Tempura: This includes lightly battered and deep-fried seafood or vegetables. It’s crunchy and delicious, offering a texture contrast to the soup.
  • Sunomono (Japanese Vinegar Salad): This is a light, refreshing salad usually made with cucumbers and sometimes seafood, marinated in rice vinegar.
  • Yakitori (Grilled Skewers): These are skewers of grilled chicken or other ingredients, offering a smoky flavor to contrast the soup.
  • Onigiri (Rice Balls): These are triangles of rice often wrapped in Nori and filled with various ingredients, like pickled plum or salmon. They are a great handheld side.
  • Tsukemono (Japanese Pickles): These are a staple in Japanese meals and add a refreshing, tangy contrast to the rich soup.

Storage And Make Ahead

  • Storage: Cool the soup completely before transferring to an airtight container. Store in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
  • Freezing: This soup freezes well. Cool completely, then transfer to a freezer-safe container, leaving some room for expansion. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
  • Make Ahead: You can prepare the soup base ahead of time and refrigerate it for up to 2 days. Cook the noodles separately and store them separately from the soup to prevent them from getting soggy. Combine the soup and noodles when ready to serve.

What Can We Do With Leftovers? 

  • Reheat and Eat: The most straightforward option is to reheat the soup and enjoy it as is. If stored correctly, the flavors can deepen over time.
  • Fried Noodles: Drain any leftover noodles from the soup, then stir-fry them with some vegetables and protein for a quick and flavorful dish.
  • Asian-Style Omelet: Add leftover noodles and vegetables to an omelet or frittata for a fusion breakfast dish.
  • Rice Topper: Pour over steamed rice with the soup broth as a flavorful sauce. Add any leftover protein or vegetables as toppings.
  • Stir-Fry Sauce: Use the leftover broth as a sauce in stir-fries for added flavor.


  • Use homemade or high-quality store-bought broth as the base for your soup to enhance the flavor.
  • Add a splash of soy sauce or tamari for a deeper, savory taste.
  • Consider using a mix of noodles for variety and texture, such as udon, soba, or ramen noodles.
  • For added protein, include ingredients like tofu, chicken, or shrimp.
  • Enhance the soup with fresh vegetables like spinach, mushrooms, and green onions.
  • Add a touch of mirin or rice vinegar for a hint of sweetness and acidity.
  • Top the soup with a soft-boiled egg for richness and texture.
  • Experiment with different toppings like nori strips, sesame seeds, or grated ginger for added flavor and visual appeal.

Ingredients List

  • 6 Cloves 6 Garlic

  • 4 4 Green Onions, Divided

  • 25 Inch Pieces 25 Dried Kombu Or Kelp

  • 7 Coins Sliced 7 Fresh Ginger

  • 1/4 Cup 1/4 Low-Sodium Tamari Sauce

  • 3 Tbsp 3 Mirin Or Sake

  • 2 Tsp 2 Sugar, Optional

  • 2 Cups 2 Thinly Sliced Shiitake Mushrooms

  • 3 3 Large Carrots, Thinly Sliced

  • 4 Cups 4 Udon Noodles

  • 2 Cups 2 Snow Peas And/ Or Thinly Sliced Napa Cabbage

  • 4 Tsp 4 Sesame Oil For Garnish, Optional

  • 2 Tsp 2 Sesame Seeds For Garnish, Optional

Step-By-Step Directions

  • Preparation Steps
    Prepare your vegetables – thinly slice the shiitake mushrooms, carrots, green onions, and fresh ginger.
  • Cooking
    Combine the sliced ginger, half of the green onions, dried kombu, and 6 cups of water in a large pot. Bring the mixture to a boil over medium-high heat. Once boiling, lower the heat and let it simmer for about 15 minutes.
    Meanwhile, in a separate pan, sauté the sliced garlic in a bit of oil until golden. Add the mushrooms and carrots, cooking until they begin to soften.
    Remove the kombu and ginger from the broth using a strainer. Add the low-sodium tamari sauce, Mirin or sake, and sugar (if using) to the broth. Stir well to combine.
    Increase the heat under the broth to bring it back to a boil. Add the udon noodles, cooking them according to the package instructions until tender.
    Once the noodles are cooked, reduce the heat again. Add the sautéed mushrooms, carrots, the rest of the sliced green onions, and the snow peas or napa cabbage. Let the soup simmer for 5-10 minutes to allow the flavors to meld together.
  • Final Touches and Serving
    Ladle the soup into bowls. Drizzle some sesame oil over each (if using) and sprinkle with sesame seeds for garnish.
  • Large Pot
  • Strainer
  • Chopsticks And Asian Soup Spoons
  • Kitchen Knife
  • Noodle Pot Or Pasta Pot
  • Bowls
  • Ladles
  • Measuring Spoons And Cups


  • For a vegetarian version, use vegetable broth instead of traditional options like chicken or beef.
  • Adjust the seasoning according to your taste preferences. You can add more tamari sauce or mirin/sake for a stronger umami flavor or adjust the amount of sugar to suit your desired sweetness.
  • Feel free to customize the vegetable selection based on your preferences or what you have available. Bok choy, bean sprouts, or bell peppers can also be great additions.
  • If using dried shiitake mushrooms, soak them in hot water for about 20 minutes before slicing and adding them to the soup. You can also use fresh shiitake mushrooms for a slightly different flavor and texture.
  • Don’t overcook the noodles to prevent them from becoming mushy. Follow the package instructions for cooking times, but aim for a slightly al dente texture.
  • Experiment with different garnishes like chopped green onions, cilantro, or a squeeze of fresh lime for added freshness and brightness.
  • Leftovers can be stored in an airtight container in the refrigerator for a couple of days. However, the noodles may absorb more liquid over time, so you might need to add some additional broth or water when reheating.
  • Adjust the spiciness by adding a dash of chili oil or red pepper flakes if you prefer a little heat in your soup.
  • Remove the kombu pieces before serving to prevent them from becoming overly chewy or tough.
  • Enjoy the Japanese Noodle Soup as a complete meal, or pair it with your favorite side dishes or appetizers for a more substantial dining experience.
