Japanese Zoodle Miso Soup: A Nourishing Twist on a Classic

Looking for a comforting, low-carb dish that’s both satisfying and wholesome? Japanese Zoodle Miso Soup is your answer. This fresh take on the traditional miso soup swaps out high-carb noodles for zucchini spirals (a.k.a. zoodles), making it a nutrient-rich option perfect for paleo, gluten-free, or plant-based lifestyles.

Let’s dive into how to make this cozy bowl of wellness right in your kitchen.

What Is Japanese Zoodle Miso Soup?

Japanese Zoodle Miso Soup combines the umami-rich depth of classic miso soup with the light, refreshing crunch of zucchini noodles. It preserves the soul of traditional miso soup—dashi (broth), miso paste, seaweed, and tofu—while replacing traditional wheat or rice noodles with zoodles for a lighter, healthier twist.

This modern adaptation is ideal for anyone looking to cut down on carbs without sacrificing flavor.

Ingredients

Here’s what you need to make two servings of this delightful soup:

• 1 medium zucchini (spiralized into noodles)
  
• 3 cups dashi broth (homemade or instant)
  
• 2 tbsp white or yellow miso paste
  
• ½ cup firm tofu (cubed)
  
• 1 tbsp dried wakame seaweed
  
• 1 scallion (thinly sliced)
  
• Optional: sesame seeds, chili oil, mushrooms, or shredded carrots for added texture
  

Instructions

1. Prepare the Dashi Broth
   
   • Heat 3 cups of dashi in a saucepan over medium heat. If using instant dashi granules, dissolve the granules in warm water as per the package instructions.
     

1. Soften the Seaweed
   
   • Add dried wakame to the pot. Let it rehydrate and expand for 2–3 minutes.
     

1. Add the Tofu
   
   • Gently add the tofu cubes. Let them warm in the broth for 2–3 minutes without breaking.
     

1. Mix the Miso Paste
   
   • In a small bowl, mix miso paste with a bit of the hot dashi broth until smooth. Stir the miso mixture back into the pot. (Never boil miso, as it destroys its probiotics.)
     

1. Add the Zoodles
   
   • Add spiralized zucchini noodles to the soup and simmer for 1–2 minutes until just tender but still firm.
     

1. Garnish and Serve
   
   • Ladle the soup into bowls, garnish with sliced scallions and sesame seeds, and enjoy immediately.

Frequently Asked Questions

Can I make this soup ahead of time?

Yes. Prepare the broth, miso, tofu, and seaweed in advance. Store the zoodles separately and add them just before reheating and serving to maintain texture.

Is miso soup gluten-free?

Most miso pastes are gluten-free, especially white and yellow miso, but always check the label. Use gluten-free tamari if adding extra seasoning.

What kind of miso should I use?

White miso (shiro miso) is the most common for soups—it’s mildly sweet and less salty. Red miso has a deeper flavor but can overpower light dishes.

Can I use pre-spiralized zucchini?

Absolutely. Pre-spiralized zoodles from the store save time. Just check for freshness and avoid any that seem watery or mushy.

Is this recipe keto-friendly?

Yes! This zoodle miso soup is very low in carbs and fits within most ketogenic guidelines.
