Is there anything better than a crisp, fall day with a delicious soup simmering on the stove?! Now, I’m not wishing away summer just yet, but I really am partial to the fall weather and warm, cozy foods that come along with it. But, to be honest, I am a huge soup fan and would eat them all season long!

This Creamy Dairy-Free Butternut Squash Soup with Caramelized Onions is super easy to make and makes a great dinner. It’s very filling, but goes great with some sourdough toast!

Can you use canned butternut squash in butternut squash soup?

Butternut Squash is a type of winter squash that grows on a vine. It has a sweet, nutty taste similar to pumpkin, and is actually called butternut pumpkin in Australia and New Zealand.

Butternut squash has a tan-yellow skin and orange, fleshy pulp with a compartment of seeds. For this recipe, you will want to cut up the butternut squash and remove the seeds.

I wouldn’t recommend using canned butternut squash in this recipe, as it is not going to have the same fresh flavor that the real thing will. You should be able to easily find a butternut squash in the grocery store when late summer rolls around.

How to Cut A Butternut Squash

One thing you must have before you try to cut a butternut squash is a very sharp, large knife. Secure your cutting board in place and cut the top and bottom off of the squash, and then cut the butternut squash in half, width wise so that you have two halves that can each stand up.


Using your sharp knife, slice the outer peel off of the butternut squash halves. Some people find it easiest to use a vegetable peeler, but I personally prefer a sharp knife.

Once the butternut squash halves are peeled, cut them in half lengthwise. One half should have the compartment of seeds, which you will want to remove with a large spoon. Then, chop the butternut squash into 1-2 inch cubes and set aside until adding them to the soup.

easy caramelized onions

The most time-consuming part of this recipe (but soooo worth it!) is caramelizing the onions. It takes about 40 minutes, but it’s hands-off and gives this soup such a great flavor!

To caramelize the onions, you will want to peel and slice your onion into rings. It doesn’t need to be perfect!

Heat a large pot (the same one you’re making the soup in) over medium heat and add a few tablespoons of oil. Once hot, add the caramelized onion and allow to cook, stirring every 5-10 minutes, on medium or medium-low heat until the onions are browned and caramelized, about 40 minutes total.

When the onions are done, add the ¼ cup of balsamic vinegar to deglaze the pan, and then it’s time to make the rest of the soup!

How to Blend a creamy soup

The best way to blend this Creamy Dairy-Free Butternut Squash Soup with Caramelized Onions is to use an immersion blender. You can purchase immersion blenders on like at places like Amazon, or any cooking store will have them. They are a must-have for creamy soups! 


The other option would be to transfer the soup to a high-power blender in batches, just be sure to leave the top open if you are transferring hot soup to the blender!
