Butternut Squash: The main ingredient of this bisque, and for good reason! Butternut squash is hearty, healthy, and absolutely delicious. It makes for a bisque that is flavorful and satiating enough to be a main dish.
Sage, Rosemary, Thyme, and Red Pepper Flakes: This delightful combination of herbs and spices makes this bisque complex and savory. Sage and thyme bring the quintessential autumn flavors and the red pepper flakes add just a little spice to warm you up.
Onions, Carrots, Celery, and Garlic: I add these four aromatics to nearly every soup I make because they give it a robust, flavorful base. If you want to avoid chopping them in the future, you can try out a homemade freezer mirepoix to have on hand.
Heavy Cream: This makes for a delicious, creamy soup that will please even picky eaters. It can also be substituted with coconut cream to make the soup lighter and dairy-free.
Vegetable Broth: Broth is part of what makes this bisque so savory! Use carton broth, vegetable stock cubes with water, or homemade broth. You can substitute for chicken stock if you desire.

How to Make Vegan Butternut Squash Bisque
One of the great things about this recipe is how easily it is made dairy-free. If you want to make it a little lighter or suitable for a plant-based diet, simply substitute the cream with a can of full-fat coconut milk. I frequently make this soup this way and it is absolutely delicious!
Can You Freeze Butternut Squash Bisque?
Yes, you can. Butternut squash bisque freezes really well in a jar, bag, or another airtight container. If you are going to freeze the soup, I recommend leaving the cream out and adding it when you serve the soup.
How to Freeze Butternut Squash Bisque
- Let your bisque sit out on the counter to cool to room temperature.
- Package the bisque into mason jars, silicone bags, or freezer bags.
- Label the bisque with the type of bisque and the date.
- Store in the fridge overnight to reduce the temperature even further. This is an optional but recommended step.
- Store in the freezer for up to a year.
How to Freeze Liquids in Jars
If glass jars are your container of choice, make sure you follow these guidelines when freezing your soup:
- Always ensure you are leaving at least 2 inches of headspace at the top of the jar.
- When you put the jar in the freezer, do not twist the lid on tightly; rather, leave it sitting loosely atop the jar. Once the liquid is frozen, you can tighten the lids to prevent freezer burn.
- Ensure the bisque has completely cooled to fridge temperature before freezing it.
How to Thaw Frozen Soup
When you’re ready to eat your bisque, I recommend pulling it out of the freezer and allowing it to thaw in the fridge for 12-24 hours. This is the easiest way to thaw it.
If you’re in a rush and need it thawed more quickly, run it under hot water until you are able to remove the bisque from its container and heat it in a saucepan over the stove.
Roasted Butternut Squash Bisque Toppings
There are so many delicious ingredients to add to the top of the soup for additional flavor, texture, and visual appeal. Here are a few of my favorites:
- Roasted pumpkin seeds or butternut squash seeds
- Fried Sage
- Homemade croutons
- A dollop of sour cream (or vegan sour cream)
- Large soup pot (I like a stainless steel pot or a Dutch oven)
- Immersion blender or high-speed blender
- Baking Sheet
Frequently Asked Questions
What can I use instead of butternut squash?
You can substitute the butternut with any other winter squash that you like. Pumpkins, kabocha squash, acorn squash, or red kuri squash are great options.
Is it necessary to peel butternut squash before roasting it?
Nope! For this recipe, we will roast the squash in its skin and scoop the flesh out once it is cooked. If you want your butternut squash to be cubed rather than pureed in its final form (say, for a salad or sheet pan meal), peeling may be necessary.
How do you thicken butternut squash soup?
If you accidentally add too much broth or your squash is on the smaller side, you may find your soup too thin. You can thicken it by simmering the soup for a while to boil off some of the water content. You can also add a roux or cornstarch to thicken it.
