Why This Recipe Works
- You can enjoy a creamy soup in just 15 minutes with only five ingredients.
- There is no need for vegetable broth as the kabocha provides the inherent natural sweetness and hearty, nutty flavor.
- It's a plant-based soup and easily adaptable for vegans by substituting the butter.
📋 Ingredients
Here are the ingredients (amounts are in the recipe card below).

- Kabocha Squash - Opt for kabocha squash with bright orange flesh and dark green skin, which offers the best sweetness and starchiness.
- White onion - Onion adds a natural sweetness to the soup, enhancing its overall flavor profile.
- Butter - Butter adds a rich flavor to the soup. If you prefer a dairy-free option, you can substitute it with your choice of cooking oil.
- Soy Milk - Use soy milk or any milk of your choice to achieve a creamy texture in the soup.
- Salt: Add a pinch or two to adjust the flavor.
🔪Instructions
Let's go over how to make this kabocha squash soup.

1. Remove the seeds and cut the kabocha into small chunks. Remove the green skin from each piece, then cut the kabocha into smaller slices.

2. Slice the onion thinly.

3. In a large pot, melt some butter and add the sliced onions.

4. Saute them over low heat for 2 to 3 minutes until they become tender and fragrant.

5. Add water and the sliced kabocha squash to the pot.

6. Cover it and bring it to a boil over medium heat. Reduce the heat to low, and let it simmer for about 6 to 8 minutes or until tender.

7. Transfer the cooked mixture to a blender. Blend until smooth, creamy consistency.

8. Return the soup to the pot and add soy milk to the soup. Add salt to the taste and turn off the heat just before it starts boiling.
Serve

Pour the soup into a bowl and sprinkle some black pepper on top to enhance the flavor. Enjoy!
Storing Tips

If you have leftover Kabocha squash soup, let it cool down and transfer it to an airtight container or a glass jar.
The soup will be stored in the fridge for up to 3 days. When reheating, microwave it, or my recommendation is to gently warm it on the stovetop over low heat.
Helpful Tips
- Blender Options: A high-speed blender is great for this recipe, but you can achieve a velvety texture with either a regular blender or an immersion blender as well. If you don't have any of these, a food processor can also be used for blending.
- Creaminess Boost: For a creamier texture, you can mix in a small amount of wheat flour or rice flour before adding water. Alternatively, coconut milk is a great addition to enhance the soup's creamy consistency.
- Adjusting Sweetness: If the sweetness of the squash is not desired, feel free to add some sugar or maple syrup to your taste.
- Edible Skin: Don't discard the Kabocha skin! It's entirely edible and can be used in other dishes.
- Spice It Up: Add grated fresh ginger or a dash of cayenne pepper to introduce some heat and depth of flavor. These ingredients will elevate the soup's taste profile with a spicy kick.
