One of my best butternut squash recipes, this soup tastes like fall comfort food in a bowl, with an Italian-style twist. The squash can be roasted in advance to save time.

Smooth and rich, the soup is a classic favorite in the fall and winter — which just happens to be the best time to cook nutty-tasting winter squash, when it’s in season.

Butternut squash soup, with benefits

  • LAYERS OF FLAVOR: Instead of boiling or steaming, roasting butternut squash intensifies and concentrates its natural sweetness — that means you don’t need to add sugars like honey, maple syrup or brown sugar.
  • LUXE TEXTURE: By using the correct ratio of squash to liquid, the pureed soup turns out thick, smooth, and velvety.
  • TIME SAVING: It’s easy to break down the prep and cooking steps so they fit into your schedule. The blended soup reheats beautifully when you’re ready to serve.

About the ingredients

I added my usual Italian-inspired recipe flair to the soup with some of my favorite flavor enhancers — Parmesan cheese, crushed red pepper, and Italian parsley.

Ingredients for preparing roasted butternut squash soup, including a split butternut squash, halved onion, fresh herbs, broth, cinnamon sticks, and heavy cream and grated cheese in small bowls.
  • Butternut squash: You’ll need one whole standard-sized squash, weighing 3-4 pounds. See my instructions below to learn how to cut the whole squash.
  • Heavy cream: This ingredient absolutely makes the texture of the soup out-of-this-world luscious and velvety. You only need 1 cup of cream to really level up the elegance factor. For a subtle spice background flavor, the cream is heated with smashed garlic cloves and a cinnamon stick.
  • Broth: Use your choice of broth — I love the taste of my homemade chicken broth or vegetable broth to make a flavorful base for the soup.
  • Parmesan cheese: Grated Parmesan cheese in this soup remind me of the inside of a pumpkin ravioli, in the best way!
  • Onion: Yellow or sweet white onion.
  • Crushed red pepper: A pinch adds just a hint of heat to the soup. You can omit it if you like.
  • Spice: A whole, cracked cinnamon stick really cozies up the flavor of the soup without hitting you over the head. You can also add in a small amount of ground ginger and nutmeg (see recipe notes).
  • Fresh herbs: Chopped parsley is the simplest way to add color and flavor to the soup. Other aromatic herbs like sage, rosemary or thyme pair beautifully with butternut squash.

How to cut a butternut squash

Instead of peeling and chopping the squash, cutting it in half and roasting it with the skin on is a big time-savor.

  1. Place a cutting board over a damp towel (so it doesn’t slide around). Grab your sharpest chef’s knife.
  2. Lay the squash sideways and slice off the top stem. Cut a thin piece off the bottom end of the squash so it sits flat.
  3. Stand the squash upright and center the knife over the top. Slice downward, see-sawing the knife as you push down, until the squash is cut into two pieces.

Serving and storing

  • Roast the squash up to 3 days in advance: Scoop out the flesh and store in a container or ziptop bag, or freeze up to one month.
  • When you’re ready make the soup, heat and infuse the cream according to the recipe, the simmer the soup, which takes about 20 minutes total.
  • Butternut squash soup keeps in the refrigerator 3-5 days, and in the freezer for 1 month.

Instructions 

Roast the butternut squash

  • Preheat oven to 400 (200C) degrees. Line a baking sheet or baking pan with parchment paper.
  • Slice the squash in half lengthwise and scoop out the seeds with a large spoon. Drizzle the flesh side of the squash with olive oil and season generously with salt and black pepper.
  • Place the squash halves cut-side down on the baking sheet. Cover with a sheet of aluminum foil and bake until the squash is tender when pierced with the tip of a knife, about 35-40 minutes depending on the size of the squash. Set aside until cool enough to handle. Scrape the flesh from the butternut squash halves with a spoon. You should have 4-5 cups of squash. At this point, you can refrigerate it in a covered container until you're ready to make the soup (up to 3 days in advance).

Make the soup

  • While the squash is roasting, pour the cream into a small saucepan and add the garlic and cinnamon stick. Bring just to a boil, then immediately remove from the heat and allow the flavors to steep 15-25 minutes.
  • Heat the olive oil in a large pot over medium heat. Add the onion to the pot. Cook, stirring frequently, until it's softened and translucent, 3-5 minutes. Pour the cream through a mesh strainer set over the soup pot (or just fish out the garlic cloves and cinnamon stick with a spoon).
  • Add the cooked squash to the pot. Stir in 2½ cups of the broth, ¼ cup of the Parmesan, 1½ teaspoons salt and the red pepper. Bring to a simmer and cook 10 minutes. Puree the soup directly in the pot using an immersion blender until very smooth (or blend in batches in a blender). Stir in more broth as needed if you prefer a thinner consistency.
  • Serve the soup in bowls, sprinkled with some parsley, chili and Parmesan cheese.

Karen’s Notes and Tips

  • Roast the squash up to 3 days in advance: Scoop out the flesh and store in a container or ziptop bag, or freeze up to one month.
  • When you’re ready make the soup, heat and infuse the cream according to the recipe, then simmer the soup as directed.
  • To add more warm spicy flavor, add 1/4 teaspoon each of ground ginger or 1/8 teaspoon of nutmeg to the cream infusion.
  • Butternut squash soup keeps in the refrigerator 3-5 days, and in the freezer for 1 month.
  • If you use a blender to puree the soup, be careful to only fill the blender jar about halfway. Hot soup expands quickly under pressure, making a mess if it explodes out of the lid.
 
If you happen to have a high-speed blender, you’ll love how super-smooth and creamy this soup will turn out. But next to that, an immersion stick blender like this one does the trick almost as well — it’s what I use most of the time.

    Hi Karen,
    I know it would be good and creamy, but can I back off of the cup of cream or even substitute something else (maybe a potato)?
    Thanks,
    Sherri

    1. Hi Sherri – Yes, you can totally make it with less or little dairy. If oat milk is okay you can substitute with that (full fat, unsweetened). Or skip the milk and add 1 cup of cooked chopped potato to the pot before pureeing. Let us know how it works for you!
