Sweet potato chowder ingredients.
  • Vegetables: Japanese sweet potato is the star of this soup, adding natural sweetness and a creamy texture. Add onion, carrot, and shimeji mushrooms to make the chowder hearty. Feel free to use other vegetables you have on hand.
  • Vegetable bouillon powder: This creates the base flavor for the soup. You can also substitute the bouillon and water with vegetable broth.
  • Rice flour: I like using rice flour to thicken the chowder while keeping it light and gluten-free. Regular flour works as well if gluten isn’t a concern.
  • Soy milk: Soy milk gives the soup a smooth, light finish. You can substitute it with regular milk or any plant-based milk, such as almond or coconut milk.
  • Miso paste: Miso adds gentle umami and richness. Use light-colored miso, like white or yellow, to keep the chowder bright and creamy.

Recipe Tips

  • Make sure the rice flour is thoroughly mixed in before adding the water. This helps the soup thicken smoothly without lumps.
  • Soy milk can separate if boiled, so keep the heat low after adding it and turn off the heat just before it starts bubbling.
  • If the chowder becomes too thick, add a splash of water or soy milk. If it’s too thin, simmer uncovered for a few extra minutes.

What To Serve With

To complement this cozy sweet potato chowder, I recommend serving it with kombu onigiri, teriyaki tofu, and pickled daikon radish

Equipment

  • Medium pot

Ingredients
  

  • ½ Onion, roughly chopped
  • 1 Sweet Potato, diced
  • ½ Carrot, diced
  • 1 cup Shimeji Mushrooms
  • 1 Tbsp Vegetable Oil
  • 2 Tbsp Rice Flour
  • 1 tsp Vegetable Bouillon Powder
  • cups Water
  • 1 cup Soy Milk
  • 1 Tbsp Miso Paste
  • Salt and Pepper, to taste

Instructions
 

  1. Prepare the ingredients: Chop the onion, and cut the sweet potato, carrot, and shimeji mushrooms into small pieces.
  2. Sauté the vegetables: Heat the vegetable oil in a saucepan over low heat. Add the sliced onion and cook until soft and fragrant. Add the sweet potato, carrot, and shimeji mushrooms, and sauté briefly.
  3. Add the rice flour: Turn off the heat, sprinkle in the rice flour, and stir until the vegetables are evenly coated.
  4. Simmer: Add the bouillon powder and water, then cook over medium heat while stirring. When it starts to boil, reduce the heat, cover, and simmer for 5–7 minutes, or until the vegetables are tender.
  5. Add soy milk and miso: Stir in the soy milk and miso paste. Heat gently and turn off the heat just before it reaches a boil to prevent splitting.
  6. Finish and serve: Season with salt and pepper to taste. Ladle into bowls and enjoy!

Notes

  • Storage: Transfer the soup to an airtight container and refrigerate. It can be stored for 3 to 4 days.
  • Make sure the rice flour is thoroughly mixed in before adding the water. This helps the soup thicken smoothly without lumps.
  • Soy milk can separate if boiled, so keep the heat low after adding it and turn off the heat just before it starts bubbling.
  • If the chowder becomes too thick, add a splash of water or soy milk. If it’s too thin, simmer uncovered for a few extra minutes.
