Why this recipe works
Butternut squash is a challenge to peel (I've knicked myself peeling squash too many times to count!) Which is why I love this squash soup recipe.
You can use fresh or FROZEN butternut squash cubes that have been already peeled and chopped to cut the prep time down to minutes! Dump the remaining ingredients into the slow cooker and let it work its magic while you go on with your day.
Ingredients
Most of the items you need for this recipe are easy to find, but I do have a few ingredient notes to share:
- 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.
- 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 prefer the regular version, hands down. 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).
Instructions
There is little more to this soup than a bit of chopping and stirring. The rest of the magic happens in the slow cooker.
- Add squash, onion, garlic, ginger, curry paste, chicken stock and coconut milk in the bowl of a slow cooker. Stir to combine. Cook for 8 hours on low.
- Puree the soup. You can either do this in batches in a blender (fill the jar only ½ full when blending hot liquids as they expand during the pureeing process) or use an immersion blender.
- Stir in fish sauce, brown sugar & butter. Season to taste with salt and pepper. Garnish with pepitas, freshly chopped cilantro and extra curry paste.
FAQS
Yes! I often freeze individual portions for quick and easy lunches on the go.
Leave a little bit of headroom in your soup containers to allow for expansion when the soup freezes solid. This soup will keep for up to 4 months in the freezer.
A few ingredient substitutions are all you need to tweak this recipe to work for vegans.
Replace the chicken broth with vegetable broth, the fish sauce with soy sauce or your favorite vegan fish sauce (or make your own vegan fish sauce at home) and omit the butter entirely.
Tip: You might want to check your curry paste, too, as some contain fish sauce.
Serving suggestions
As written, this soup has a mild curry flavor. It's a great base for people who aren't huge curry fans. I like to serve this soup with extra curry paste on the side so people can stir in as much as they like.
Also recommended: chopped fresh cilantro and roasted and salted pepitas.
You can serve this soup as a starter or add some bread and salad for a light meal.

Recipe
Slow Cooker Curried Butternut Squash Soup
Ingredients
- 8 cups of peeled cubed butternut squash
- 1 large onion chopped
- 3 garlic cloves chopped
- 1 ½ tablespoons peeled and grated fresh ginger root
- 3 - 4 tablespoons green curry paste plus more for serving
- 4 cups chicken stock
- 1 can 13.5 ounces regular coconut milk
- 3 tablespoons fish sauce
- 1 tablespoon brown sugar
- 1 tablespoon butter
- Salt and pepper
- Chopped cilantro optional
- Roasted salted pepitas, optional
Instructions
- Add squash, onion, garlic, ginger, curry paste, stock and coconut milk to the bowl of a large slow cooker. Stir to combine. Cook on high for 4 hours or low for 8 hours.
- Puree the soup using an immersion blender or a regular blender.
- Stir in the fish sauce, brown sugar and butter. Let soup sit for 15 minutes before serving to allow all the flavors to meld together. Add salt and pepper to taste and garnish with fresh cilantro and pepitas.
Notes
- This soup is pretty mild as written. Feel free to stir in an extra spoonful of curry paste if you want a more pronounced curry flavor.
- This soup freezes beautifully. I often freeze individual portions to pull out for easy lunches.
- If using a blender to puree the soup, only fill the jar halfway. Hot soup expands when it is blended. If you fill the jar too full, the lid will blow off and create a very memorable mess.

Esther Bradley-DeTally says
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.
Anna says
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!

Bring on the soups!! I think they're my favorite part about the cooler months, there's nothing that warms you from the inside out like a comforting, creamy bowl of soup. Looks delicious!
Anna says
Me, too, Nicole! If it has to be cold outside, at least there is soup!
Laura @MotherWouldKnow says
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!
