Easy & Versatile Instant Pot Butternut Squash Soup Recipe (Stovetop and Slow Cooker Directions Too!)

This Instant Pot butternut squash soup recipe is rich and creamy, laced with warm spices, and has a sweet earthy flavor that’s enhanced with a touch of brown sugar. It’s the perfect fall soup, and the best part is, it’s made from start-to-finish in the Instant Pot with just 15 minutes of hands-on prep time!

Every fall my mom makes an incredible squash soup. It’s creamy and velvety with warm spices, a hint of sweet maple, and rich squash flavor.

She makes it with four types of squash: butternut, acorn, buttercup, and pumpkin. And she roasts them first to bring out their natural sweet, earthy flavor.

My mom’s soup is truly something special, and if you have about three hours to spend in the kitchen I highly recommend it. (You can take a look at my mom’s squash soup recipe. Just don’t judge my pictures too harshly, I had only been blogging for about six months, lol!)

But what about those crazy busy crisp fall days that deserve a great butternut squash soup?

This pressure cooker butternut squash soup recipe features the same creamy texture, warm spices, subtle sweetness, and rich winter squash flavor. However, I simplify the process a little and make it in a fraction of the time!

Instant Pot Butternut Squash Soup Recipe

This nutritious butternut soup recipe was inspired by my mom’s squash soup. It has the same richness, creamy texture, and subtle sweet spiced flavor.

There are two main differences between this soup compared with my mom’s soup. For starters, I only used butternut squash instead of a combination of four types of winter squash. Additionally, I make the whole soup from start-to-finish in an electric pressure cooker.

Instead of roasting the squash to bring out its natural sweet, caramelized earthy flavor, I sauté it until it starts to turn golden and caramelize in spots. It’s a huge time-saver!

Once the butternut squash is caramelized a bit, I add all the other ingredients to the Instant Pot and let it do its thing. This squash soup only needs to cook for 8 minutes at high pressure.

Ingredients

In this section I explain the ingredients and give substitution ideas. For the full recipe (including ingredient amounts), see the recipe card below.

• Unsalted butter – to sauté the onion and squash
• Onion – for depth of flavor
• Butternut squash – this winter squash is the star of the show; if you’re using a whole squash you’ll need to peel it, remove the seeds, and cut it into cubes
• Vegetable stock – or chicken stock for richer flavor
• Light brown sugar – this adds a subtle sweetness with notes of molasses that bring out the naturally sweet, earthy flavor of butternut
• Salt and black pepper – these are basic spices that elevate the flavor of almost anything
• Cinnamon, ginger, cloves, and nutmeg – these warm spices are similar to pumpkin pie spice mix, and they pair beautifully with butternut squash; instead of the cinnamon, nutmeg, ginger, and cloves, you can use 1 teaspoon of pumpkin pie spice
• Heavy whipping cream – to add rich flavor and creamy texture to our silky smooth soup
