Complete list of ingredients is located in the recipe card below.
- Butternut Squash – You’ll need about 7-8 cups of peeled and diced butternut squash, so make sure you get a big one or 2 small or medium-sized ones. The amount doesn’t have to be exact though so don’t worry too much!
- Onion & Garlic – These two aromatics add a lot of flavour so I wouldn’t recommend skipping them. For a flavour twist, you could also add some fresh ginger here.
- Carrot – Gives the soup more texture, color, and a naturally sweet flavor. You can always add a bit more if you like, it doesn’t have to be exact.
- Cinnamon & Nutmeg – The combination of these warming spices adds depth to the sweetness of the butternut squash.
- Vegetable Stock – Any vegetable broth or stock works. You can use homemade or store-bought carton or cubed broth.
- Coconut Milk – Optional but I really like this addition for added richness and creaminess.
How to Prepare the Squash
There are different ways to prepare a squash for cooking but this is how I like to do it.
- Chop the bottom and the stem off of the squash.
- Use a vegetable peeler to remove the skin.
- Chop the squash into rounds until you get near the bottom where the seeds are located.
- Cut the squash in half and scoop out the seeds and “guts” with a spoon.
- Chop the squash into cubes.
Quick Tip: Cut the butternut squash cubes roughly the same size so they cook evenly.
How To Make the Soup
Step 1. Add all the ingredients to a slow cooker and cook on high for 3-4 hours or low for 5-6 hours until the squash is soft and tender.
Quick Tip: Add just enough broth to barely cover the squash. Too much liquid will thin out the soup and we want it nice and thick and creamy! I like to use 4 cups.
Step 2. Once it’s cooked, either blend directly in the slow cooker using an immersion blender or carefully transfer to a blender and mix until smooth and creamy. Blend in the coconut milk now, if using.
I prefer to use a blender for an extra creamy finish. You may need to do this in a few batches.
Season with salt and pepper if needed and serve as is or topped with a drizzle of coconut milk, fresh herbs and lime.
- Swirl in some vegan sour cream, cashew cream, or plain coconut yogurt.
- Top with fresh chopped basil, chives, cilantro, or green onion.
- Toasted nuts or seeds such as pumpkin seeds, cashews, peanuts or hemp seeds give a great crunchy texture.
- Add more protein with baked tofu, tempeh or chickpeas.
- Top with roasted chickpeas.
- Stir in some greens at the end such as spinach, kale or arugula for a little extra nutrition.
- Serve with your favourite bread or try this hearty seed bread.
This soup makes an excellent base to customize to your personal tastes. Try switching up the flavors in this soup by using these ingredients and methods:
- Roasting or sautéing the veggies first. For extra flavor, you can roast the squash, carrots, and onion or saute the onion, garlic, and carrots for a few minutes before adding to the slow cooker. These methods help bring out the flavors of the vegetables.
- Make it butternut squash sweet potato soup. Swap half the butternut squash for peeled and cubed sweet potato.
- Add cauliflower. Cauliflower makes a good addition to this soup. Try adding 1-2 cups of chopped cauliflower florets. Use a bit of extra liquid if needed.
- Make it curried butternut squash soup. For a curried soup, add up to 1 tbsp of curry powder to the slow cooker with the rest of the ingredients. Red curry paste is really good too for a Thai-inspired soup.
- Add an apple. Apple and squash is a classic flavor combo. For an extra layer of flavor and sweetness, add 1 chopped green apple to the slow cooker with the rest of the ingredients.
- Make it spicy. To add some heat, add up to 1 tsp of cayenne pepper or chili flakes to the slow cooker. I like it to have a little heat, so I usually add 1/2 tsp chili flakes.
- Try it with kabocha or acorn squash. This soup can be made with any kind of squash such as kabocha, acorn, or even pumpkin.
- Cumin and coriander make a nice spice combo or can be used in addition to the cinnamon and nutmeg.
- Use fresh or dried sage and thyme instead of cinnamon and nutmeg for a more savory flavor that pairs well with the sweetness of the squash.
If you don’t have a slow cooker, no problem. This soup can easily be made on your stovetop:
- Start by sauteing the onions, garlic, and carrot for 5-10 minutes in a splash of broth.
- Add the rest of the ingredients and simmer until the squash is tender, about 10-15 minutes.
- Blend the soup in a high-speed blender, pour and enjoy.
Storing & Freezing
- Storing: Leftovers can be stored in the fridge for up to 5 days and can be reheated on the stovetop or by using the microwave.
- Freezing: Cooled soup can be frozen by pouring it into an airtight container or freezer-safe bag for up to 3 months. Defrost in the fridge overnight before serving.

I have high expectations…and this recipe exceeded them! I followed the recipe, adding an apple, the optional coconut milk, and more salt to taste…and it was perfect! Highly recommend.
Thanks, Liz! I’m so happy to hear it met your expectations…apple is a great addition! Thanks for letting me know.
Love this soup! Made it a few times now, thank you for such a gorgeous, healthy and easy recipe 🙂
I love the way you cook squash, thanks for sharing!
Really delicious and creamy. Hubby loved it and he’s very hard to please
So glad you enjoyed it!
This is a great recipe! Easy and delicious, perfect for fall. I’ve also been enjoying bulking it up with quinoa and white beans.
I and my family love this soup, it freezes well and is a vegan option for the family members who eat vegan, yet hearty enough to stand up to the meat eaters appetites. I make it according to directions listed and have experimented with the various spice suggestions, we all like it savory with the turmeric, sage and thyme with cayenne to boot! I top ours with pumpkin seeds or tri colored tortilla strips I enjoy a splash of heavy cream in my bowl as well.
Awesome! I love that you’ve tried different spice combos. Sounds so good! Thanks for the review.
it says 6-8 servings but how much is a serving? a cup?
Hi Kelly, I’m not sure the exact serving size just that it makes 6 large or 8 slightly smaller servings. I’d guess if you mske 6 servings they’re around 3 cups each. I hope you enjoy it!
Just curious on calories per serving
Sorry, I’ll add that in tomorrow when I have a moment! It’s very low calorie though, just carbs with little to not fat.
Can I make a this recipe with heavy cream instead of
The coconut milk?
That should be fine but I don’t have any experience cooking with heavy creamy so I can’t guarantee it! Let me know if you try it.
Have made butternut squash soup before, I put carrot and a bit of chilli in instead of the garlic and onion which is how I usually make it on the stove so fingers crossed it comes out okay 🙂
I hope you enjoy it!
Can you freeze this soup
Can I use chicken stock instead of vegetable stock?
Yes, that is fine. It wouldn’t be vegan or vegetarian of course but the recipe will come out the same. Enjoy!
I made this soup last night and it is delish! I had a small-ish butternut squash, it’s made enough for 4 as a main meal, and just followed the guidance about the stock just covering the squash and it came out beautifully. So smooth and tasty. I added in a bit of chilli and served it with a little bit of feta crumbled on top. I’m already looking forward to having it again tomorrow!
I did find it took a bit longer to cook, closer to 3 hours on high, but that may have just been because I didn’t chop the squash small enough!
I’ll definitely be making this again, thanks so much for sharing this fab recipe.
Yummy, sounds great! So glad you enjoyed it!
This soup is amazing! I did add a little sour cream at the end for a more creamy texture. But wow!!
Yum!! So happy you liked it.
Hi…just tried this 4 ingredient recipe…. this is my first time making butternut squash soup I love so much.Had to slow cook on high for about 3 hours as opposed to 2, but that was no problem. Added kosher salt and nutmeg… no pepper…loving it!
Followed the recipe exactly. It made a tasteless,boring soup. Noone wanted to eat it.
I’m really sorry to hear you didn’t enjoy it. Thanks for your feedback on the recipe.
Followed your recipe with the exception of adding a bit of nutmeg…..soooo easy and delicious!!!! Thanks for sharing!
I have made Butternut Squash soup on the stove that was delicious. Today,I made this today because I thought it was a marvelous, easy time saving way to make the soup. You cannot imagine my surprise when after 2 hours the squash was not done. I have an immersion blender and the consistency was very thin. We tried the thin soup only to not even like the flavor. Looks like this gets dumped. What a waste of time!
I’m so sorry it didn’t work out for you! I’ve made it a number of times with success and haven’t had any issues with the squash not cooking or it being too thing. So sorry! I wish I could tell you what went wrong. Thanks for the feedback.
I have this is the slow cooker now, I added some paprika and chilli powder to give it an extra kick. Fabulous recipe look forward to seeing more from you. xx
I love this butternut squash soup. I made it last night on the stovetop. It cooked up really well. I added some ginger to spice it up. Didn’t add nutmeg or cinnamon. Just the veggies! Had some broth that I had made previously and frozen so I added that as well. I had a small ish squash and it was enough for 3 servings.
I enjoy a great butternut squash soup, but don’t constantly have time to earn one. Tossing everything in a slow-moving stove would give me that time. Among my favorite products to use throughout the loss period is squash soup. Will most definitely be doing this.
I love, love, love a good butternut squash soup (my favorite thing in the world in winter), but don’t always have time to make one. Throwing everything in a slow cooker would give me that time. Will definitely be doing this. Thanks. And lovely photos too.
