Nothing is more satisfying on a chilly fall or winter day than a bowl of homemade soup. Fortunately this Slow Cooker Thai Curried Butternut Squash Soup can be a reality more quickly than you think, thanks to the help of your trusty slow cooker and a handful of uber-flavorful ingredients.

The best butternut squash soup in the crock pot

Nothing beats having a homemade dinner 90% complete when you walk in the door after a busy day. Which is why I BIG PUFFY HEART my slow cooker.

This curried squash soup recipe couldn’t be simpler. There is no fancy layering technique to the ingredients. It’s merely dump, stir, set and forget!

Load up the slow cooker in the morning (this one is my current favorite), and you’ll be greeted with a heavenly aroma that will make you extremely grateful for the few moments you spent earlier that morning prepping the soup.

Soup that tastes like curry

I adore the flavors of Thai curry dishes, so naturally a soup that includes many of the same signature elements is a total winner in my book:

  • Green curry paste: You will also find red (and occasionally yellow) curry paste on the shelves. The differences primarily come from the ingredients and color of chilis used (red = red chili peppers and chili powder, green = green chili peppers, coriander, basil and lime leaf). Green curry paste is generally a touch sweeter than red curry paste, which has traditionally been a bit spicier.
  • Freshly grated ginger: Never grated ginger before? It’s quite simple: grab a knob of fresh ginger at the store, peel the skin using a vegetable peeler and grate it using a microplane grater. If you’re short on time, you can also buy fresh ginger paste in either refrigerated or frozen form.
  • Coconut milk: I’ve made this recipe using lite coconut milk and regular coconut milk and I much prefer the regular version. I think Bon Appetit said it the best when it described lite coconut milk as the 2% of coconut milks. The result is slightly grainy and less rich.
  • Fish sauce: My go-to fish sauce is Red Boat. It’s available at many Asian markets as well as Amazon. But if I’m out of that, Thai Kitchen is a solid choice (and is sold at Target).

Butternut squash, onion, garlic, broth and a finishing touch of brown sugar and butter round out the ingredient list. If you make Asian dishes frequently, you might just have all of these ingredients in your pantry. If not, they are readily available at any well-stocked grocery store.

Tip: Peeling and chopping a butternut squash can be a near-death experience (especially if you haven’t had your knives sharpened in a while.) Save yourself the time and hassle by picking up peeled and cubed butternut squash at the grocery store. Have leftover squash? Make our Roasted Butternut Squash Naan Pizza!

How to safely puree hot soup in the blender

To get the uber creamy soup texture like you see in the pictures, you really need to give the soup a generous spin in the blender before serving it. But if you’ve ever tried to puree hot liquids before, the results can be “explosive” if you don’t follow a few simple tips:

  1. Allow the soup to cool for at least 15 minutes before adding to the blender. 
  2. Fill your blender half way full – no more! Hot liquids expand when they blend and can blow the top off the blender resulting in a mess at the very least and possibly a burn.
  3. Securely attach the lid to the blender and cover with a towel. Hold the top closed while blending as extra insurance against explosions. 
  4. Pour pureed soup into a serving dish or pot. Repeat puree process in stages with remaining soup. 

My Blendtec does an amazing job of creating a smooth, velvety texture to this soup. However, if you don’t mind soup with a less smooth consistency, a standard blender or even an immersion blender works great, too. 

Freeze homemade soup

Soup is one of those recipes that freezes beautifully with minimal effort. I often freeze this Slow Cooker Thai Curried Butternut Squash Soup in individual containers. They are perfect to pull out for lunches when the fridge looks rather bare.

Frozen soup lasts about 4-6 months in the freezer. Just be sure you leave a little bit of headroom in your containers when you fill them. Soup expands when frozen so you want to make sure you have adequate headspace in the container to allow for the expansion.

How to reheat frozen soup

If I’m thinking ahead, I pull a frozen container of soup out of the freezer and pop it in the fridge overnight to defrost. But if I’m not that organized, I’ve also done a quick defrost in the microwave or dumped the frozen block into a saucepan on the stovetop over low heat to slowly warm and heat through.

Serving this soup for a group? I prepare the recipe as written then add small bowls of extra green curry paste to the serving area so guests can swirl a little more in their bowls for an extra curry kick. I also load it up with some salty pepitas and ample amounts of fresh chopped cilantro for a bit of crunch and bright flavor in every bite.

    OMG! This soup looks amazing and right up my alley. We are soup lovers and honestly have soup and sandwich or soup and quinoa cake night once a week in my house. It’s the easiest and best cold weather comfort food. I also love that there is always leftovers for the kid’s lunches and mine as well. I have never used green curry paste, so that will be something new for me to try. Beautiful job on the photos!

      Thanks for the kind words, Jackie. I agree; I think we definitely have similar styles, and I’m positive you’re going to love experimenting with green curry paste. Enjoy!

    I made this warm yumminess again tonight and this time I used my pressure cooker. Same prep time, but only 18 minutes until I had veggies soft enough to purée. Next time I will reduce the liquid by about 2 cups–there’s so much less evaporation with the pressure cooker–I didn’t end up throwing all the liquid in the blender with the veggies. I compensated for any potential lost flavor by stirring in more curry paste. We loved it!

      Perfect soup for today’s snowy weather! I’m so intrigued by your pressure cooking. You’ll have to give me a tutorial the next time you’re in town (because you always travel with your pressure cooker, right?!?) 🙂

    This soup was SO yummy! The slow cooker really simplifies the prep and buying pre-cut squash really helps too. This will go into our regular rotation!

    I’m convinced! Signed up for your site. I love the photography. The site is not only beautiful but very easy to follow and use. I tried posting to email and Facebook and both worked wonderfully. I love that the full recipe and comments are both immediately available without doing backflips. Our taste in food meshes wonderfully. I’m excited to begin receiving your posts. This soup looks delicious. Will try it next week. I’ve already made 2 of your recipes today and it’s not even noon. Slept late until 9am so I’ve been busy. That is a great compliment and atta girl. Job well done.

    Would Red curry paste work? Or is it a totally different flavor? Thanks

    Was wondering if you know if this would freeze well? I love soups but it’s just me so I like to freeze half so I can enjoy the whole thing (just not all at once)! Love you site, adore your recipes – thank you!

    Please ignore my prior question. If I’d only read the post from the beginning (not just the recipe) I’d have seen that YES it does freeze well. Oops! Thanks again 🙂

    I love this soup because it looks simple, but the flavors seem complex. In the cold weather e’ve been having recently, a butternut squash soup sounds fabulous too!

    Boy, I’m not a cook and my eyes lock in the back of my head at too many ingredients. But, I’m intrigued. So intrigued I’ll go out and buy a slow cooker. Now, this is the crux of my query: where does one find fish paste and curry paste, and I like it very mild; what kind of curry paste-red or green or half recipe?

    I do like soups, time for a change for me I guess; Shuck off fear of cooking time.

      Hi Esther, fish sauce and thai curry paste are both located in the Asian ingredients aisle of my grocery store. I suspect it would probably be the same for you if you shop at a large store. You can choose red or green curry paste. If you’re concerned about the flavor intensity, try adding only half of the suggested amount. You can always stir in more if you like. It’s pretty mild as written since my kids eat it. Enjoy!

    I added 2 serrano chiles and the juice of 2 limes to make it more Thai-like.

    Yummy. I did make some drastic changes. i used Carrots instead of squash. Carrots were on sale. I also added a little lime juice as suggested in one of the comments. It was VERY good and I am sure tomorrow it will be even better as these kind of soups get better with age. It was a little thicker than I like so for my second helping I added a little more chicken broth and a little more curry paste. Thanks

    I should have mentioned that I cooked it on the stove and not in a crock pot worked well in shorter time

    Is there a good substitute for the coconut milk? Allergies!

      Hi Suzanne, I’ve never tried substituting anything else for coconut milk, but you could try heavy cream to replicate a similar consistency (minus the coconut flavor, of course). You might also try a nut milk of some sort (almond or cashew), but that would result in a thinner soup. I’d be curious to hear your results. Please report back if you give it a try!

        Hello, Anna.

        I made this with fat-free half and half, curry powder instead of the green curry paste, and a splash of maple syrup instead of the brown sugar. It was really good. I am always experimenting with different ingredients! I just wanted to let you know how it turned out, I really enjoyed the soup. I made it again and doubled the batch. I froze in lunch size portions to take to work. I either have soup or a light salad for lunch. Thanks for the great recipe. Regards, Suzanne – Littleton, CO

    I love this recipe so much! We actually use it as a curry base and add chicken and veggies with rice. It’s sooooooo good.

    I added an extra tablespoon and a half of green curry and it was good! Next time I would halve the amount of fish sauce though. Lime sounds good, maybe I’ll try that next time too.

    YUM! Sign me up for pretty much anything with curry, coconut, or ginger, and this has all three! I just made this and it is definitely a keeper. I did diverge from the recipe just a bit…only had red curry and couldn’t find green at my local store (small town), but would love to try the green next time. I also added a little fresh spinach at the end (just because I needed to use it and I didn’t have cilantro). I also roasted the butternut squash seeds and sprinkled them on when serving for a little crunch. Next time I will cut back a bit on the chicken stock, though, as I would prefer it just a bit thicker. Looking forward to having this for lunches this week and also putting some in the freezer for later.
