Quick and Easy Acorn Squash Soup

We love to enjoy large, warm bowls of rustic soups and stews in the fall and winter. And velvety smooth soups made with squash are some of our favorites to cozy up with!

Butternut squash and pumpkins are classic harvest soup ingredients. However, I feel like the acorn squash is often the forgotten squash. Or the one used for decor then tossed out because no one has any idea what to do with it. But truly, it is amazingly flavorful! So, I decided to share my delicious squash soup recipe for this often overlooked gem.

With a thick rind, acorn squash usually requires a long roast in the oven to soften it, making the Instant Pot ideal for cooking whole acorn squash.

From start to finish, including prep and pressure building, this easy acorn squash soup recipe takes less than 30 minutes to prepare. It’s ideal for those busy weeknights when you want to feed the family something satisfying but don’t have a lot of time – or energy!

And, thanks to the secret ingredient – a sweet but tart apple – the recipe creates a rich and creamy soup with just a hint of sweetness. It is a gluten free soup that’s great to have by itself as a light dish or serve with warm bread or other sides for a comforting dinner.

In fact, I almost always keep a few squash on hand around the house… Not only are they are festive to look at, right there is nearly everything you need to make a scrumptious meal in a flash. Use squash for your decor, then toss them in the Instant Pot for a yummy soup that everyone will love!

How to cut an Acorn Squash

The best way to cut an acorn squash is to first cut off the top (underneath the stem) and bottom (at the tip) so you have a flat top and bottom.

Then, place the squash upright and cut the squash vertically into two halves. See how it’s done in the video below:

How to Make Squash Soup in the Instant Pot

Pour the water into the bottom of the pressure cooker pot. Add the trivet or sling (optional) to the bottom and stack the cut acorn squash and apple inside the pot.

TIP: If using a silicone sling, like mine, fasten the straps before pressure cooking so it is easy to lift out afterward.

Set pressure cooker to high pressure for 6 minutes.

Quick-release once the pressure cooking cycle is complete. Carefully remove the acorn squash and apples with tongs and set them aside on a plate or bowl.

Drain and reserve the leftover water for later.

Set the pot to saute and melt the butter then add the onions. Cook until lightly golden and translucent. Add the garlic and saute.

Add the chicken broth, reserved water, salt, cinnamon, and nutmeg to the pressure cooker pot. Let the mixture heat in the Instant Pot on saute while you prepare the squash.

Carefully scoop the softened squash meat from the skin using a large spoon or ice cream scoop. Or, peel the skin from the squash.

Add squash to the pressure cooker pot cook on high pressure for 5 minutes.

Use the quick-release method. Add heavy cream to the soup. Use an immersion blender (see notes below on using a blender) to blend the squash soup until thick and creamy.

Garnish with thyme and a pinch of ground pepper before serving.
