Ingredients

  • 1 kabocha squash approx. 3 pounds, halved and seeded, medium
  • 3 tablespoons olive oil divided
  • 5 scallions both green and white parts
  • 1 tablespoon ginger peeled and grated, fresh
  • 2 cloves garlic peeled and minced
  • ¼ cup White miso paste gluten-free
  • 4 cups vegetable broth low-sodium
  • 2 cups water
  • salt sea salt
  • 1 tablespoon rice vinegar
Optional Toppings:
  • 2 tablespoons sesame seeds toasted
  • ¼ cup microgreens optional

Instructions

    Cup of Yum
  1. Pre-heat the oven to 400 F degrees. Line a baking sheet with parchment paper.
  2. Slice the squash into smaller pieces and drizzle them with 1 tablespoon of the olive oil. Lightly sprinkle the squash with ½ teaspoon of sea salt. Set them cut side down. Roast for 30 minutes (or until it is soft and tender when pierced with a knife), rotating the baking sheet half way through the process for even roasting. When the squash is cool enough to handle, scoop the flesh into a bowl. You should have 3 to 3 ½ cups of squash. Using the back of a fork lightly break them. No need to puree. It is okay if they are in chunks.
  3. Meanwhile, heat the rest of olive oil in a heavy bottom pan over medium heat. Add in the scallions and cook, stirring occasionally, until softened, 5-6 minutes.
  4. Stir in the ginger and garlic and cook for 30 seconds.
  5. Add in the squash, vegetable broth, and water. Cover the pot, bring it to a boil, and let it simmer for 20 minutes.
  6. Place the miso paste into a bowl. Ladle 1 cup of the soup liquid into the bowl. Whisk until combined and smooth. Pour the mixture into the soup.
  7. Remove it from the heat. Using a hand blender, puree the soup until smooth. Taste for seasoning and add more if necessary. Alternatively, you can puree the soup in a blender in batches.
  8. Put it back on the stove and bring the now-pureed kabocha squash soup to a boil one last time.
  9. When ready to serve, ladle into bowls and sprinkle with sesame seeds. If preferred, garnish with microgreens.

Notes

  • A note on adding more salt: For seasoning, since different varieties of miso paste can taste different I recommend tasting the soup before adding additional salt.How to StoreHow to store: If you are a small family like us, feel free to store the leftovers in an airtight container in the fridge for up to 4 days.To freeze, allow the soup to cool completely.
