The Instant Pot is an incredible tool in the kitchen for making dishes that once took a long time to make. You can drastically cut down the cooking time for dishes like this easy Butternut Squash Soup in the Instant Pot, which only takes 8 minutes to make in the pressure cooker vs four hours in the crock pot.

Of course, you can also make Butternut Squash Soup on the stove top and we’ll give instructions for that below too, if you don’t have an Instant Pot.

The best thing about this soup is that everyone can enjoy it. It’s vegetarian, vegan, gluten and dairy free. The soup turns out creamy and delicious, without the addition of any cream.

Ingredients You’ll Need

  • Cooking oil – I always use olive oil, but you can use any cooking oil you like, such as canola, sunflower, avocado.
  • Onion – I use a small white or yellow onion, chopped
  • Carrot – Peeled and chopped. Carrots add a bit of sweetness.
  • Butternut squash – This recipe uses raw butternut squash, so there’s no need to pre-cook the squash. Peeled and cut into chunks.
  • Seasonings – Salt and rosemary, dried or fresh
  • BrothChicken broth or vegetable broth. You can use a boxed chicken broth, or mix water with a cube of chicken bouillon.
  • Butter – Use salted butter. The butter adds a nice richness at the end of the cooking process.
  • Optional garnish – Cream, red pepper flakes, chives, roasted pumpkin seeds, paprika, and grated nutmeg

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.

Do I Cook the Butternut Squash First?

There are two ways you can make butternut squash soup. One is to first roast the butternut squash in the oven to cook it, then blend it with the soup and heat it on the stove top. The other is to cook the butternut squash from raw in the Instant Pot. This recipe uses raw butternut squash, so there’s no need to pre-cook the squash.

Not having to pre-cook the squash cuts down on prep and cook time, and it creates less dishes (which is always a good thing, in my book). Using the Instant Pot allows the squash to cook quickly, while melding the flavors of the vegetables into the broth. It turns out full of flavor!

If you don’t have an Instant Pot and want to roast the squash first, you can follow this guide. When I do it this way, I peel the butternut squash with a vegetable peeler, cut it in half (remove the seeds), place it upside down on a baking sheet with a silicon mat, then roast it for 1+ hour on 375 degrees F, until the flesh is fork tender.

How to Make Instant Pot Butternut Squash Soup

1. Prepare and Sauté the Vegetables

One of the most important aspects of a good butternut squash soup is the flavor that develops from sautéing the onion and carrot.

Chop the vegetables into small cubes that are all the same size, so they cook evenly, then add them to the Instant Pot with some cooking oil on the Sauté setting. Season with half the salt. It will only take a few minutes to sauté them.

Keep a close eye on it, because the Sauté mode on the Instant Pot is really HOT and the veggies can easily burn if left unattended.

2. Add the Butternut Squash

Once the vegetables are a bit softened, add the butternut squash. I prefer to cut up the squash into chunks that aren’t too big, about 2-3 inches square. You can use fresh butternut squash or frozen raw squash. If you’re using frozen cooked squash, you can cook it for half the time listed in this recipe.

Season the squash with the remaining salt and the rosemary. Sauté the squash with the vegetables for about 3-5 more minutes. Again, keep a close eye on it and stir it regularly to keep it from burning and sticking to the bottom.

3. Add the Broth and Pressurize

Add the broth and the garlic and give it all a big stir, making sure to get the browned bits up off the bottom of the pan. Then turn off the Sauté mode.

Close the lid of the Instant Pot and make sure the valve is set to pressurize. Press the Pressure Cook button and set it for 10 minutes.

4. Blend

When the cooking time is done, you can carefully release the pressure and open the lid. Use an immersion blender to blend the soup until it’s smooth.

I love the immersion blender for this because it allows you to blend the soup in the original pot and you don’t have to get the blender involved. However, if you don’t have an immersion blender, it’s fine to use the blender. Make sure you take the plastic top piece off to allow the heat to vent as you blend.

Once the soup is blended, 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

How to Make Butternut Squash Soup Without an Instant Pot

If you don’t have an Instant Pot, it’s just as easy to make this soup on the stove top. The instructions are the same for sautéing the veggies and adding the butternut squash, only you’ll be using a 3 quart pot on the stove, instead of the Instant Pot.

Once you’ve added the broth to the pot, cover the pot and simmer over medium-low heat for 40 minutes. The butternut squash should be fork tender.

You can then proceed to blending the soup and adding the butter.

The Instant Pot is a great way to make dishes in a shorter amount of time. Check out this beef stew recipe made in less then an hour.

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.

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.

      Hi Sandra, sorry for the confusion. You would add the salt and rosemary along with the butternut squash when you add it to the Instant Pot.
