Make 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.

Love curry recipes? This creamy squash soup uses many of the same ingredients!

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 10 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. 

Can you freeze this homemade curried butternut squash 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.
