Instant Pot Butternut Squash Soup in two bowls

Here it is, folks! Your new favorite soup EVER! A creamy and smooth butternut squash soup kicked up a notch with some Thai flavors. Make ahead and freezer-friendly, too!

I made this in an electric pressure cooker (aka Instant Pot), but have included stovetop instructions too – so everyone can make this!! (You could also put it in a slow cooker, as well). This instant pot soup can be made in about 30 minutes in the instant pot, and a quick whiz with an immersion blender, a swirl of coconut milk and dinner is served.

Why this recipe works:

The vegetables become super soft making them perfect for blending into a velvety smooth soup.

You can eat it right away, or you can do what I do – and pack myself lunch for the week, or put some away in the freezer for a quick dinner, or lunch whenever one is needed. I actually keep some of my soup in the freezer at work, in case of a super busy day, when I can’t leave the office to get food and didn’t have time to grab anything from home in the morning.

Quick and easy. I know, I know – I should plan ahead, but sometimes, I just don’t. I have a lot going on! Using this recipe, I got these, plus a couple of bowls for eating right now.

Tips for peeling Butternut Squash – Pop the squash, unpeeled, in the microwave and heat for a minute. The heat softens the skin, so it’s easier to peel!
Play around with the curry paste quantities. If you like it super spicy, instead of adding more curry paste, add a pinch of cayenne.
You can use heavy cream in place of the coconut milk, but it won’t have that delicious coconut flavor that goes so well with Thai flavors.

Blending the soup

Be careful if you are using a blender to puree the soup. Allow to cool a little first, and hold your hand on the lid to avoid explosions!

Substitutions/Additions

Can you freeze Butternut Squash Soup?

Absolutely! I like to put it in single-serve containers and freeze up to a few months. It’s great to have a few different soups to choose from in the freezer, so I typically make a double batch of this. One pot for tonight, and one for the freezer.

Is this recipe Gluten-Free?

Technically, yes it is. Do check the labels on the stock and spices you use if this is a requirement for your diet.

Instant Pot Cooking Terms Explained

What is Natural Pressure Release – aka NPR?

A natural release happens when the cooking time is over and the valve is left closed. The pressure decreases without doing anything. Your Instant Pot will automatically switch to the Keep Warm setting.

As soon as it switches to Keep Warm the pressure will begin to drop and will release the pressure by itself. You’ll know it’s done – when the pin drops.

What is Quick Release?

Quick Release means to let the Instant Pot release pressure naturally slowly for a few minutes (usually between 5 and 15 minutes). After the time has elapsed, switch the valve to “venting” to quickly release any remaining pressure. The pressure will release to a point where the pin drops, and you can open the lid.

Ingredient Notes

The full list of ingredients and quantities is found in the printable recipe card below.

Butternut Squash – you can buy this fresh and peel and chop it. Or, you can buy it frozen, OR you can buy it in the produce department already peeled and chopped.
Onion – dice this up finely so that it blends well at the end.
Vegetable Stock – make your own roasted vegetable stock, or vegetable broth, or use store-bought. Chicken stock is also totally acceptable if you don’t care about this being vegetarian
Salt & Ground Black Pepper – use ½ tsp salt if using table salt vs kosher
Coconut Milk – keep a little out for topping at the end. Coconut cream and heavy cream also work for this.
