  • Rehydrate the Seaweed: Place the dried seaweed (wakame) sheets in a bowl of water. Let them soak for about 5-10 minutes until they expand and become tender. Once rehydrated, drain and chop the seaweed into bite-sized pieces.
  • Prepare Slow Cooker: Start by preheating your slow cooker. Most slow cookers have low and high settings; for this recipe, choose the low setting.
  • Combine Ingredients: In the slow cooker, add the rehydrated seaweed, dried shiitake mushrooms, julienned carrots, grated ginger, minced garlic, and sliced green onions. Give them a gentle stir to mix.
  • Add Broth and Seasoning: Pour in the vegetable broth, soy sauce, mirin, and sesame oil. These ingredients will form the savory base of your soup. Stir everything together in the slow cooker.
  • Cook Slow and Steady: Cover the slow cooker and let the ingredients cook on the low setting for about 4-5 hours. Slow cooking allows the flavors to meld and intensify.
  • Boil Udon Noodles: While your slow cooker works its magic, cook the udon noodles separately according to the package instructions. Usually, it takes about 8-10 minutes. Drain and set them aside.
  • Miso Paste: About 20-30 minutes before you’re ready to serve, ladle out some of the hot broth from the slow cooker into a bowl. Dissolve the miso paste in the broth and then return the mixture to the slow cooker. This helps to evenly distribute the miso flavor.
  • Season and Garnish: Taste the soup and adjust the seasoning with salt and pepper as needed. You can also add a bit more soy sauce or mirin if you prefer.
  • Serve: To serve, place a portion of cooked udon noodles in a bowl. Ladle the seaweed and mushroom soup over the noodles. If you like, top with a halved boiled egg and some extra green onions for a beautiful garnish.
  • Enjoy: Your slow cooker seaweed noodle soup is ready to be enjoyed. The flavors are deep and comforting, making it a perfect meal on a cold day or whenever you crave a taste of Japan’s seaside comfort.

Tips for making Seaweed Noodle Soup

The secret to rich flavors – the slow cooker.

Cooking Tips

  • Rehydrate Seaweed with Care: When using dried seaweed (wakame), be sure to soak it in a bowl of water until it’s tender. Over-soaking can make it slimy, so follow package instructions for the best results.
  • Don’t Rush the Slow Cooker: The beauty of a slow cooker lies in its slow and steady cooking. Avoid turning up the heat, as low and slow is key to allowing the flavors to develop fully.
  • Customize Seasoning: Adjust the seasoning to your preference. If you like it saltier, add a bit more soy sauce. If you prefer sweetness, adjust the mirin. Taste-testing is your friend.
  • Fresh Ingredients Matter: While slow cooking works its magic, use fresh ingredients for garnishing. Fresh green onions, for instance, will provide a vibrant, crisp contrast to the soup.
  • Miso at the End: Adding miso paste towards the end of cooking prevents it from losing its delicate flavor. Dissolve it in a bit of hot broth before incorporating it into the slow cooker.
  • Experiment with Garnishes: Besides the suggested garnishes, feel free to get creative. Try adding some nori strips, toasted sesame seeds, or a drizzle of chili oil for an extra kick.

Serving Suggestions

Seaweed Noodle Soup
Enhance your meal with a side of japanese pickles
  • Side of Pickles: A side of Japanese pickles, known as tsukemono, complements the umami flavors of the soup. Options like takuan (pickled daikon) or gari (pickled ginger) are excellent choices.
  • Garnish Galore: Be generous with garnishes. Sprinkle with toasted sesame seeds, fresh cilantro, or even a dash of shichimi togarashi (Japanese seven-spice blend) for a flavorful twist.
  • Green Tea Pairing: To elevate your meal further, serve it with a cup of Japanese green tea. The subtle bitterness of green tea harmonizes beautifully with the savory soup.
  • Cold Beer Match: If you’re looking for a more casual pairing, consider enjoying your Seaweed Noodle Soup with a cold Japanese beer or a glass of crisp sake.
  • Light Appetizer: While this soup is hearty, you can serve it as an appetizer before a larger Japanese meal, such as sushi or tempura. It’s an excellent way to start a culinary journey.
