If you love soup, the Instant Pot is the tool for you because you can make it in a fraction of the time as you won’t on the stove top. It’s now possible to make a fantastic soup for lunch or dinner in under 15 minutes.

I often have an extra butternut squash hanging about the house from our Imperfect Box. The easiest and tastiest thing to make is Butternut Squash Soup. It’s great for a quick meal, and even better as left overs.

Why Use An Instant Pot?

The Instant Pot is one of the most useful kitchen appliances you can buy, because it drastically cuts down on the cooking time for developing flavors in soups and stews, getting tough cuts of meat tender, and even baking a cheesecake. And there are many accessories that will help you get more out of your Instant Pot.

If you don’t have one yet, check out our guide on which one to buy. Also see our guide to How to Use an Instant Pot for more information.

Ingredients in Butternut Squash Soup

For this soup, you’ll need a few basics, plus one lovely butternut squash (though you can use frozen if you need to). Here’s what you can gather:

  • Butternut Squash – you’ll peel it and cube it. You can use frozen butternut squash. The soup doesn’t need any additional time to cook even if you use frozen. A medium sized butternut squash is perfect for this recipe – around 2-3 pounds in weight.
  • Onions and carrots – These add to the aromatics of the soup and are essential for flavor.
  • Chicken of Vegetable Stock – you can use either type of broth that you like. Use vegetable to keep it vegetarian.
  • Seasonings: Salt and rosemary are all the seasonings you need for great flavor.
  • Optional garnishes: cream, red pepper flakes, chives, roasted pumpkin seeds, paprika, grated nutmeg

PRO TIP: Whole butternut squash is cooked easily in the Instant Pot using this recipe.

Equipment Information

  • Instant Pot: I use a 6-quart Instant Pot Duo Plus for this recipe. You can also use a 3-quart or 8-quart pot if that’s what you have. You just need to increase the amount of liquid for the 8-quart.
  • Immersion Blender: This is a very handy kitchen tool to have around. If you don’t have one you can always use a blender. Just be careful, hot liquid can explode in the blender.

How to Make Butternut Squash Soup

1. Prepare and Sauté the Vegetables

To ensure that the vegetable cubes cook evenly, chop them into small, same-sized cubes and add them to the Instant Pot with a little oil on the sauté setting. Season with half the salt.

When the onion and carrots are sautéed, they develop the flavor that makes this butternut squash soup so good, so don’t skip this step unless you’re really in a hurry.

Sautéing them won’t take long. Keep an eye on the Instant Pot because the sauté function is really hot and the vegetables can easily burn if left unattended. If your pot is getting too hot, set it to low instead of high.

2. Add the Butternut Squash

Once the vegetables are a bit softened, about 5 minutes, add the butternut squash.

Peel and cut the squash into chunks that aren’t too big, about 2-3 inches square. You can use fresh butternut squash or frozen squash.

Season the squash with the remaining salt and the rosemary and add them to the Instant Pot with the other vegetables. You’ll sauté them for another 3-5 minutes to develop a bit more flavor.

Again, to keep it from giving you the burn notice, keep a close eye on it and stir it regularly.

3. Add the Broth and Cook

The next step is to pour in the broth and garlic and scrap the browned bits off the bottom of the pan. Turn off sauté mode before you do this.

Close the lid of the Instant Pot and make sure the valve is set to pressurize. Press the Pressure Cook button and set the time for 8 minutes.

4. Blend the soup

After the time is up, you can manually release the pressure, if you wish. If you’re not in a hurry, you can allow the pressure to release naturally.

The best way to puree the soup to a silky consistency is with an immersion blender. You can stick the blender right into the soup and puree it until it’s smooth.

This can take a bit longer than you might think. At first the soup will be smooth, but not yet silky. You need to blend beyond that point until the soup is aerated and starts to look silky.

Note: If you don’t have an immersion blender, it’s okay to use a regular blender, instead. Make sure you take the plastic top piece off to allow the heat to vent as you blend, because hot liquids will erupt in the blender.

5. Add garnishes and serve

Add the butter and stir it in. Taste it to make sure it’s seasoned to your liking. Add a bit more salt until the flavor is right for you.

Optional Toppings

There are a few additional toppings you can use to dress up your soup, but it’s just as tasty without any garnish.

  • A drizzle of cream to the top
  • Red pepper flakes
  • Croutons
  • Roasted pumpkin seeds – Try this recipe to make them at home.
  • A sprinkle of paprika

Tips & Notes

  • If you don’t have an Instant Pot, you can make this in the slow cooker or in a pot on the stove. Add all the ingredients to the slow cooker and cook over low heat for 4 hours. On the stove, cook for 30-40 minutes over medium-low heat with the lid on.
  • If you want to roast the butternut squash first, put the peeled halves on a baking sheet for 1 hour at 375° F. Then scoop out the flesh, add to the vegetables either in the IP or on the stovetop. Puree and serve.
  • If you don’t have an immersion blender, you can blend this soup in a blender.
  • For a more creamy soup, add 1/4 cup cream to the blended soup. Do not add the cream before cooking in the Instant Pot or it will curdle.
  • To just add a touch of cream, add heavy cream or sour cream as a garnish to the top of the soup when serving.

    I’m so excited to see this for instant pot. This is one of my all time favorite soup recipes and I was going to try to figure out how to convert. I’ll be making this weekend.

    This is the butternut squash soup recipe I’ve been looking for. The only thing I did different, I added a little cinnamon and I used leftover, cooked, mashed squash. After cooking and blending, it was so rich and creamy. My husband added a little of Smoky Paprika to his portion and that gave it a really good different flavor.
