What is this squash? This kabocha squash?
Kabocha squash is a Japanese winter squash, also known as Japanese pumpkin. Its kind of a cousin of butternut and acorn but has a sweeter taste like sweet potato
Basically, she's a goddess of fall deliciousness we're going to cook up in all the ways possible starting with this roasted kabocha squash soup.

Some ideas for using this winter squash:
- puréed smooth
- tempura battered and fried
- roasted in salads or as a side
- in pastas like ravioli or gnocchi
How to roast kabocha squash
First, we have to break down this squash-pumpkin combo.
Like a pumpkin, the squash is tough to cut into. Be sure to use a sharp knife. I start by cutting the ends, slicing in half, scooping out the seeds, then cut into 1 to 2-inch slices for roasting.
You can also microwave the squash for 4 or 5 minutes to soften it or roast it for about 20 minutes, then cut off the ends and slice.
Veggies roast at 400°F with a drizzle of oil and salt and pepper sprinkle in our house. Roast until it's fork tender.
Is the skin edible?
Kabocha squash skin is edible, for this soup recipe we will remove the skin though.
Tips for Making Roasted Kabocha Squash Soup
Honestly, this baby is oh so simple, there's not a lot to it!
- For an easy throw together meal, roast the squash in advance!
- Don't over cook the leeks! They cook fast so watch out they don't burn.
- It's easier to remove the skin after roasting the squash than peeling it before,.
- Let the squash cool after roasting until you can handle it. The soup can simmer on low if the squash needs more time to cool.
- Use an immersion blender to puree the soup smooth right in the pot. If you need to use a countertop blender - be careful for the hot liquid! It's worth the investment for the immersion blender.
For a fun way to serve the soup, you can use hollowed out halves of acorn squash!
Ingredients and Substitutions
You just need a handful of ingredients for roasted kabocha squash soup and it's pretty versatile for substitutions.
- kabocha squash, about 3 to 4 pounds
- great north beans
But if you're unable to get your hands on any of the above, here are some easy swaps you can make:
- Substitute butternut, acorn, or hubbard squash
- Navy beans, cannelini beans, or butter beans can swap for the great north beans - I've even made this soup with pinto beans and the taste was great.
- Half a yellow onion is a quick swap for the leek.
- Heavy cream, milk, or a plant based cream would work perfectly especially if you wanted a vegan soup
- Veggie stock or chicken stock can be used
- If you don't want to use the white wine, just give the pan a splash of stock!
What to serve with your soup
Personally, I've been eating this soul warming deliciousness for lunch and dinner. It's just so satisfying!
My favorite way to eat this is with some cast iron grilled sourdough bread with melty cheese on top. I keep them open faced so it's like toast meets grilled cheese.
This whole wheat sourdough loaf is a standard in our house and there's always a slice somewhere, but I'm also loving a softer all purpose pumpkin and sage version. Brown bread is such a tasty option too with a little sweetness to the bread - it also makes great croutons!
Soup and salad is a natural combination too! Pear and cheddar salad has the same play on sweet and savory, but is still light enough to eat alongside soup.
