This is hands-down our favorite fall vegetable soup – roasted butternut squash soup with apple, leeks and spice-infused cream give the soup a velvety texture and beautiful flavor.
I can’t think of a dish that warms me up inside and out the way roasted butternut squash soup does.
It’s rich and satisfying, and practically begs to be made and enjoyed in the fall and winter – which just happens to be the time these nutty-tasting winter squashes are at their best.
As usual, I gave this soup recipe my usual Italian flair with some favorite flavor enhancers – Parmesan cheese, crushed red pepper and Italian parsley.
But I have to say, this might be my best butternut squash soup yet.
While testing out the recipe, I thought butternut squash soup with apple sounded really appealing.
A small peeled, chopped apple enhances the natural sweetness of the butternut squash and you don’t even know it’s there.
That means there’s no need to add any sugar in the form of honey, maple syrup or brown sugar.
Butternut squash soup without dairy
If you’re looking for a vegan butternut squash soup without cream or butter, um, this isn’t it (sorry!)
Check out my vegan recipe for Butternut Squash Soup with Ginger and Orange instead!
While I’m not a huge fan of overly creamy soups, I still wanted to add a bit of luxury to this otherwise basic recipe.
Heavy cream (1 cup total) absolutely makes the texture of the soup out-of-this-world luscious and velvety.
Amazingly, you don’t need that much cream to really level up the elegance factor.
For even more seductive flavor, I heated the cream with smashed garlic cloves and a cinnamon stick, and then let it steep for a few minutes.
That simple infusion gives the soup a subtle hint of spice and savory garlic when you taste a spoonful, without hitting you over the head.
It just tastes lovely and balanced, without overpowering the delicious flavor of butternut squash.
Roasting butternut squash for soup
Butternut squash makes one of the best-tasting soups ever.
But that usually means you have to deal with a whole squash – all the peeling and cutting can feel like a chore.
Halving the squash and roasting it in the oven is an easy way to cook it.
While the squash bakes cut-side down on the baking sheet, it steams and roasts at the same time, resulting in soft squash along with irresistible caramelized edges.
At that point it’s simple to just scoop out the soft flesh with a big spoon and add it to your soup pot for a quick simmer with the rest of the ingredients.
How to cut a butternut squash
- Put the squash on a cutting board and grab your sharpest chef knife.
- Lay it sideways and slice off the stem. Cut a thin piece off the end of the squash so it can sit flat on its bottom.
- 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.
- Use a spoon to scrape out the strings and seeds.
Make butternut squash soup in advance:
This is a pretty hands-off recipe once the squash is roasted.
You can even roast the squash days in advance. Scoop out the flesh and store in a container or ziptop bag.
When you’re ready to eat, heat the cream, simmer the soup with the squash and puree – it takes about 20 minutes total.
The finished butternut squash soup will last in the refrigerator for up to 5 days, and in the freezer for 1 month.

Get the Recipe:
- 1 3-pound butternut squash
- Extra-virgin olive oil
- Kosher salt
- 1 tablespoon ghee, butter or olive oil
- 2 leeks, white and light green parts sliced in half lengthwise and thinly sliced
- 1/2 cup chopped onion
- 3 1/2 cups low sodium vegetable stock or water
- 1 cup heavy cream
- 3 garlic cloves, peeled and smashed
- 1 cinnamon stick
- 1/2 cup chopped Italian parsley
- Crushed red chili flakes (optional)
- 1/2 cup grated Parmesan cheese
- Preheat oven to 400 degrees and line a baking sheet with parchment paper.
- Slice the squash in half lengthwise and scoop out the seeds with a large spoon. Drizzle the inside of the squash with olive oil and season with salt to taste. Place cut-side down on the baking sheet and put in the oven. Bake until the squash is tender when pierced with the tip of a knife, 30-35 minutes. Set aside until cool enough to handle.
- Meanwhile, heat the ghee, butter or olive oil in a large pot over medium heat. Add the leeks and onions to the pot. Cook, stirring frequently, until the they're softened, 5-7 minutes.
- Put the cream, garlic and cinnamon stick in a small pan and bring just to a boil. Remove from the heat and allow the flavors to steep 15 minutes.
- Scrape the flesh from the butternut squash halves and add to the pot. Stir in the stock or water and 1 teaspoon salt. Simmer 15 minutes. Puree the soup directly in the pot using an immersion blender until very smooth (or blend in batches in a blender). Pour the cream through a small mesh strainer into the soup pot (or just fish out the garlic cloves and cinnamon stick with a spoon).
- Serve warm in bowls, sprinkled with some parsley, chili and Parmesan cheese.
- The soup can be refrigerated up to 5 days and frozen up to 1 month.
- If you use a blender to puree the soup, be careful to only fill the blender jar about halfway - hot soup expands, making a mess if it explodes out of the lid.
I always recommend that every kitchen have at least two heavy-duty rimmed sheet pans.
Good quality pans won't warp in the oven, and you will use them constantly.
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 and it's what I use most of the time.
If you'd rather skip the cream this soup will still be fantastic. Instead, leave it out and add 1 chopped garlic clove and 1/2 teaspoon ground cinnamon to the onion-leek mixture in step 3.
To use cubed squash instead of roasting a whole one, start with 4 cups peeled and cut squash. Use 4 cups of stock in step 5 and simmer 30 minutes, or until the squash is fork tender. Proceed with the blending to puree.
