Winter squash season is here! As soon as fall hits my kitchen counter is full of seasonal local squash varieties. I love them all, butternut squash, acorn squash, honeynut squash, spaghetti squash, and my all-time favorite is Kabocha Squash. Nuttier, rich, and sweeter than most other squash varieties. 

Why you will love this recipe

There’s so much to love about Kabocha squash

  • It makes silky-smooth squash soup with vibrant color and earthy squash flavor.
  • Kabocha squash puree can easily step in for butternut squash or pumpkin in your favorite fall recipes. Think sweet bread, pancakes, soups, and chilis or you can even swirl the puree into your morning oatmeal.
  • Kabocha squash is a nutrition powerhouse loaded with fiber, powerful antioxidants like alpha-tocopherol, beta-carotene, and beta-cryptoxanthin, and a host of vitamins and minerals.
  • Simply served, this squash only really needs a little grass-fed butter or ghee, salt, and pepper to become a lovely side dish that can stand in for mashed potatoes creating the perfect fall dinner with simple roast chicken.

There’s even more to love about cooking Kabocha squash in the Instant Pot:

The instant pot has officially earned a coveted spot in my kitchen as an essential tool. Seamlessly cooking all types of winter squash is truly one of the Instant Pots (or any pressure cooker) superpowers.

  • You’ll have cooked kabocha squash in under 30 minutes
  • This cooked squash can be made into a creamy soup by blending it with vegetable broth and a handful of raw cashews.
  • A few spoonsful swirled into mac and cheese is magic.
  • Pieces of the squash make a lovely addition to salads. You could even substitute kabocha squash for the pumpkin in my favorite pumpkin vinaigrette dressing.

How to Make

STEP ONE: Wash kabocha squash to remove any dirt or debris. Pour 2 cups of water into the instant pot. Place the trivet/steamer basket inside of the Instant Pot and place a whole (uncut!) Kabocha squash on top of the trivet. Lock the lid, turn to the sealed position, and cook on manual for 25 minutes.

When the pressure is complete, perform a quick-release of the valve and remove the lid.

Test to see if the squash is done by inserting a knife deep into the squash, if the knife goes in super smooth like slicing through warm butter the squash is done. If you get resistance, then cook for an additional 3-5 minutes.

I found 25 minutes was the perfect amount of time for a large 4-5 lb. kabocha squash

STEP TWO: Carefully remove the squash from the instant pot and place on a cutting board. After the squash has cooled down for a bit cut in half and scoop out the seeds with a spoon. You can discard the seeds or save them and toast for a garnish or snack.

The skin is edible, but I prefer to scoop the flesh out of the skin and discard it.

FAQ

What does Kabocha squash taste like?

Kabocha squash tastes like a cross between pumpkin, acorn squash, and sweet potato. The flesh of the squash has a drier texture than pumpkin but when blended in soups it becomes velvety and smooth. It is sweet, rich, and nutty.

Can you eat the seeds of Kabocha squash?

The seeds from a kabocha squash are edible but many prefer to remove the outer layer of the seed which can be tough. They can be roasted like pumpkin seeds and used as a garnish or snack.

Can you eat the skin of the kabocha squash?

Yes, the skin is 100% edible and is very high in fiber. If you are sensitive to fiber I would limit the amount of skin that you eat.
