Can acorn squash be used in soup?

You bet ya! When it comes to squash soup, butternut squash seems to get all the love but acorn squash is not one to be missed. Much like butternut squash, acorn squash works very well in soup. Acorn squash is a type of winter squash that is a source of complex carbohydrates that is rich in fiber and a wide variety of micronutrients, including Vitamin C, potassium, and magnesium, and its sweet yellow-orange flesh makes a delicious, rich, and creamy soup when roasted and blended.

What You’ll Need

Here are the ingredients you’ll need to make this roasted acorn squash soup:

Acorn Squash: Because you can’t make acorn squash soup without acorn squash! Once roasted this squash has a lightly sweet and nutty flavor with a buttery texture, which makes it the perfect foundation for this creamy soup.
Onion, Carrots, and Celery: A classic mirepoix mix as the foundation of this squash soup.
Garlic Cloves: Some fresh garlic as a pungent compliment to the sweet squash and spices.
Nutmeg and Cinnamon: Some essential fall spices to add an extra bit of warmth and sweetness.
Salt: To balance out the sweet and savory flavors.
Chicken Broth: Be sure to use chicken broth in this soup because a soup made with water just doesn’t provide the same level of flavor.
Butter and Olive Oil: To cook the veggies and add some healthy fats at the same time.

Swaps and Variations

If you’re concerned about sodium content, use a low-sodium chicken broth and reduce the salt as needed.
If you’d like to make the soup dairy-free, swap the butter for additional olive oil.
If you’d like to make the soup vegetarian or vegan, replace the butter with additional olive oil and use vegetable broth instead of chicken broth.

How to Make Acorn Squash Soup

This recipe is inspired by warming, sweet, and savory fall flavors with hints of cinnamon and nutmeg paired with nutty roasted squash, here’s how to make it:

Roast the acorn squash. Cut the whole acorn squash in half, leaving the skin on, and remove the seeds. Place it cut side down on a baking sheet and transfer it to the oven to roast until the flesh is fork tender.
Sautée the mirepoix. Add the chopped onion, carrots, and celery to a large pot with melted butter and olive oil and cook until tender and the onion is translucent.
Warm the spices. When the mirepoix is tender, add the cinnamon, nutmeg, and salt and heat for a minute until fragrant.
Remove the squash skin. When the squash is cool enough to handle, gently remove the exterior skin until only the yellow flesh remains.
Mix the soup ingredients. Add the acorn squash flesh to the pot with the veggies and spices, cover with broth, bring to a boil, and then reduce to a simmer to allow the flavors to combine.
Blend it up. Once the soup has cooked, puree or blend it until rich and creamy. Taste and adjust seasoning with salt and pepper as needed.
Serve and enjoy! Serve the soup with a sprinkle of pumpkin seeds, a drizzle of olive oil, and, if you want it extra-creamy, add a splash of heavy cream.
