This rich, velvety slow cooker Curried Butternut Squash Soup recipe is packed with Thai-inspired flavors and conveniently made in the slow cooker. Perfect for busy weeknight meals!
Nothing is more satisfying on a chilly fall or winter day than a bowl of homemade soup.
Fortunately this 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, Thai-inspired ingredients.
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.
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).
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.
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.
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.
