I was taking inventory of my Instant Pot soup recipes, and I remembered how much I enjoyed my Instant Pot sweet potato soup. What else is orange and perfect for autumn? Butternut squash. And that’s where the idea for this soup came from. I then decided to make a stove top butternut squash soup that’s almost identical to this recipe for those who still want the soup but don’t own an Instant Pot. 

I wanted this soup to be nice and thick and hearty, so I went easy on the liquids and added a potato the second time I tested it (the starch helps to thicken it up). I think it’s always better to have to add some more broth while you’re blending it up than ending up with a too-watery soup.

How to quickly peel a butternut squash

In my experience, using a sharp knife is the best way to peel a butternut squash quickly and easily. The peel is very thick, so I find that potato peelers don’t work so great. I cut the squash in half and then into quarters, and then I just use the knife to basically cut the peel off. I ensure the chunks are stable on the cutting board so I don’t have any accidents. Or, you can be more precise and peel it with a knife like you’d peel an apple. Either way works. I am sure there are plenty more tricks out there. If you have any handy squash peeling tips, let me know in the comments. 🙂

Recipe notes:

  • To save time, you can always buy pre-cut butternut squash. I’d aim for between 3-4 lbs. since once you trim the skin off the squash you’re left with a bit less than the 4 pounds of whole squash.
  • This soup freezes well for up to 3 months (or keep it in the fridge for a few days).
  • If you want to add a bit of zing to this soup, add in a teaspoon or so of fresh grated ginger. 
  • Try throwing a peeled and cut-up apple in here for something a little different.
  • This is the Instant Pot model I use, and I use this Oster immersion blender.

Serving suggestions:

Try serving this soup with a nice slice of crusty bread or some homemade croutons. I sprinkled some Trader Joe’s Everything But The Bagel seasoning on top to give the photos some texture, and it tastes really good.

Instant Pot Butternut Squash Soup

This Instant Pot butternut squash soup recipe is silky, healthy, thick, and packed with fall flavors. Total comfort! It's easily made vegetarian (or vegan) if needed. 
Prep: 15 minutes
Cook: 15 minutes
Inactive time: 15 minutes
Total: 45 minutes
Servings: 6

Ingredients 

  • 4 pounds butternut squash peeled, seeded, & cut into pieces
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1/2 medium onion chopped
  • 3 cloves garlic minced
  • 1 large carrot peeled & sliced
  • 1 large Russet potato peeled & diced
  • 3 cups chicken or veggie broth
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • Salt & pepper to taste
  • 1 (5.4 ounce) can coconut milk (I used full fat)

Instructions 

  • Prep your squash (cut it into roughly 1.5" pieces), onion, carrot, and potato. To easily peel a squash, I cut it into quarters and use a knife to cut the peel off since it's thick, and I find potato peelers don't do a good job.
  • Add the oil, butter, and onion to your Instant Pot. Sauté for about 5 minutes.
  • Add the garlic, followed by the broth, cinnamon, nutmeg, carrot, potato, and squash to the Instant Pot. Close the lid, set the valve to "sealing", and cook on high pressure for 10 minutes. It'll take 10-15 minutes for your IP to get up to pressure.
  • Once the countdown has finished, you can either do a quick pressure release right away or let the pressure release naturally.
  • Blend the soup using either a stick/immersion blender (that's what I used) or a regular blender. Do this carefully (you may want to let the soup cool for a while first).
  • Stir in the coconut milk and season with salt & pepper as needed (I was fairly generous with both - I would add at least 1/2 teaspoon salt).

Notes

  • I used one of those tiny cans of Thai Kitchen coconut milk. If you can't find a small can, use 1/2 of a regular size can. You can leave out the coconut milk if you wish, but I like the added silkiness and coconut flavor it adds.
  • I usually end up buying two smaller squashes because I can't always find one that's around 4 pounds.
  • If you want the soup to be very thick, reduce the broth to 2.5 cups.
  • Inactive time indicates the time it takes the Instant Pot to get up to pressure and release pressure (with quick release).
  • This is the Instant Pot I use.
  • Here's the stove top recipe if you don't want to use an Instant Pot.

    This is now my favorite butternut soup. Soooo good! I did substitute cream for the coconut milk.
