How to Make Roasted Butternut Squash Soup

These are the step-by-step instructions for this easy butternut squash soup recipe. Jump to recipe card for the printable instructions.

Roast the Squash and Garlic

Cut the squash in half and scoop out the seedy centers. Cut a whole garlic bulb in half crosswise and rub both the squash and garlic with olive oil. Roast them face down with olive oil and salt at 425°F for 40-50 minutes. Set it aside until it’s cool enough to handle.

Blend it Together

While it’s cooling, saute the onion with olive oil or butter. Transfer it to a countertop blender. Scoop the roasted squash from the skin and add it to the blender with the maple syrup, broth, and spices. Squeeze the roasted garlic cloves out of the skin.

Does your blender have a soup preset? Use that! If it doesn’t, blend until smooth then transfer back to the stock pot and simmer to heat. You can use an immersion blender too, but I’ve found a stand blender works best.

Serve and Enjoy!

Transfer the soup back to a large pot and simmer to keep warm. Serve hot soup with fresh herbs like crispy sage or fresh thyme, a swirl of cream or sour cream, or toasted pumpkin seeds.

Why Roast the Butternut Squash?

Roasting the squash in the oven first makes this delicious soup so easy! There are two major reasons I’ve been roasting my squash for soup for years:

  • No dicing required! Just cut it in half and roast the butternut squash in two halves. I tested this recipe by dicing the squash because I thought more caramely surface area on the squash might make a difference, but there wasn’t a large enough difference for the amount of work it requires.
  • Depth of flavor: roasting vegetables, especially ones with sweet undertones, caramelizes all the sugars and adds a rich and sweet flavor.

Variations and Add-Ins

  • Make it creamy: blend in coconut milk to keep it vegan or try heavy cream or creime fresh for a creamy texture.
  • Add apples: for sweetness if you have them!
  • Curried butternut squash soup: omit the nutmeg and cinnamon and replace them with 1 teaspoon of curry powder and a pinch of turmeric.
  • Use acorn squash: swapping another winter squash is easy!

What to Eat with Butternut Squash Soup

Enjoy this soup as an appetizer, side, or main dish! I typically serve it with a salad or sandwich for a light lunch or dinner. Here are a few different ways:

Storing Leftovers

Allow the soup to cool and store it in an airtight container in the fridge for up to a week. Butternut squash soup freezes well laying flat in a freezer bag for up to 3 months. Thaw overnight in the fridge and reheat on the stove.
