This easy butternut squash soup has become my go-to fall lunch because it's creamy without any cream, the squash does all the work. A green apple adds a tart note that keeps it from being too sweet, and fresh thyme and rosemary make it taste like you spent hours simmering it. The Instant Pot gets it on the table in about 25 minutes, which is hard to beat on a busy weekday.

Why You’ll Love This Butternut Squash Soup

Fast and hands-off. The Instant Pot does the heavy lifting, just sauté the aromatics, add everything else, and let it pressure cook for 10 minutes. You get a deeply flavored soup in under half an hour.
Creamy without dairy. The butternut squash breaks down into a silky puree all on its own, so this soup is naturally vegan and gluten-free. No need for cream or butter.
A surprising secret ingredient. A green apple brightens the soup with a gentle tartness that balances the sweet squash. It's a small addition that makes a big difference.

Key Ingredients for the Best Butternut Squash Soup

Butternut squash, Look for a medium squash (about 3 pounds). To save time, buy pre-cut cubes from the produce section. If you're cutting it yourself, a sharp vegetable peeler makes quick work of the skin.
Green apple, A Granny Smith or similar tart apple is ideal. It adds acidity that cuts through the richness of the squash. Don't skip it, it's what makes this soup feel lighter.
Fresh thyme and rosemary, Dried herbs won't give you the same bright, aromatic flavor. Fresh sprigs are easy to find and infuse the broth beautifully. Just pull the leaves off the stems before blending, or fish out the stems after cooking.

Kitchen Tools for Butternut Squash Soup

Instant Pot (or a large pot for stovetop, or a slow cooker)
Immersion blender (or a regular blender, blend in batches and let soup cool slightly first)
Chef's knife and cutting board
Vegetable peeler (if you're peeling fresh squash)

Tips for Making Butternut Squash Soup in the Instant Pot

Start by sautéing the onion, carrot, celery, and garlic right in the Instant Pot using the Sauté function. Cook them for 3 to 5 minutes until they soften, this builds a flavorful base. Then add the broth, squash, apple, and seasonings. Secure the lid, set the valve to seal, and cook on high pressure for 10 minutes. When the timer goes off, do a quick release of the pressure. The squash will be tender enough to puree easily.

For the smoothest soup, use an immersion blender directly in the pot. If you're using a regular blender, let the soup cool slightly first, then blend in batches, only fill the blender halfway to avoid splashing. You can also use chicken broth instead of vegetable broth if you're not worried about keeping the soup vegetarian.

Expert Advice for a Better Butternut Squash Soup

The green apple does more than add flavor, its natural acidity helps the soup taste bright and balanced, even though there's no cream. If you use a sweet apple like Fuji or Gala, you'll lose that contrast, so stick with a tart variety. Fresh herbs are worth the extra step here: dried thyme and rosemary can turn bitter during pressure cooking, while fresh sprigs release their oils gently and leave a clean finish. If you want a thicker soup, let it simmer uncovered for a few minutes after blending to reduce some liquid. For a thinner consistency, stir in extra broth or water until it looks right.

Butternut Squash Soup Variations to Try

If you don't have an Instant Pot, you can make this soup on the stovetop. Sauté the aromatics in a large pot over medium-high heat, then add the remaining ingredients, reduce the heat to low, and simmer for 20 to 30 minutes until the squash is soft. For the slow cooker, combine everything and cook on low for 6 to 8 hours or on high for 3 to 4 hours. Blend either way with an immersion blender or in a regular blender.

To change up the flavor, stir in a can of coconut milk after blending for a richer, slightly tropical twist. A pinch of cayenne or a small knob of fresh ginger added with the broth gives the soup a gentle kick. For a heartier meal, top each bowl with crispy chickpeas or crumbled bacon.

What to Serve with Butternut Squash Soup

A bowl of this soup is satisfying on its own, but a few toppings make it feel special. Try a drizzle of heavy cream or coconut milk, a sprinkle of pepitas or chopped candied pecans, and a few fresh herb leaves like sage or parsley. Homemade croutons add crunch, and crispy pancetta or bacon brings a salty, savory note.

For a full meal, pair the soup with cornbread, buttermilk drop biscuits, or Parker House rolls. A simple green salad or a shaved Brussels sprouts salad with apple and walnuts would round out the fall flavors nicely.

How to Store Leftover Butternut Squash Soup

Let the soup cool to room temperature, then transfer it to an airtight container. It will keep in the refrigerator for up to 5 days. Reheat it in the microwave or on the stovetop over medium-low heat, stirring occasionally. If the soup thickens after chilling, stir in a splash of broth or water to bring it back to the right consistency.

How to Freeze Butternut Squash Soup

This soup freezes beautifully, so it's worth making a double batch. Let it cool completely, then pour it into freezer-safe containers or zip-top bags. Leave about an inch of headspace to allow for expansion. Freeze for up to 3 months. To thaw, move the container to the refrigerator overnight. Reheat gently on the stovetop or in the microwave, adding a little broth if needed to loosen it up.

Best Ways to Reheat Butternut Squash Soup

For the quickest reheat, use the microwave: heat in 30-second bursts, stirring between each, until hot. On the stovetop, warm the soup over medium-low heat, stirring occasionally, until it's steaming. If the soup seems too thick after being refrigerated or frozen, stir in a splash of vegetable broth or water. Avoid boiling it, as that can dull the fresh herb flavors.
