This Butternut Squash, Sweet Potato and Pumpkin Soup is my harvest mash of all 3 Autumn vegetables that share the same season and bright orange color. One Dutch oven, one blender, 50 minutes, and canned pumpkin means no roasting required.
This soup sautés squash, sweet potato, onion, and garlic until they start to caramelize, then simmers everything with pumpkin puree, warm spices, and broth before a spin with the blender turns it silky. I let these vegetables caramelize longer than usual and that extra sauté time is the whole trick. A finishing splash of cream, a scatter of pumpkin seeds, and a few crunchy croutons on top, and BAM you've got the kind of soup you've always wanted to warm you up.

Squash, Sweet Potato, Or Pumpkin?
This soup doesn't make you pick, and that's the point. Butternut squash, sweet potato, and canned pumpkin puree each do a different job in the pot, so using all three gets you something none of them can do alone.
Butternut squash is the lightest of the three, with a nutty, slightly vegetal flavor that keeps the soup from turning into liquid dessert once maple syrup and warm spices are in the mix. Sweet potato brings more natural sugar and starch, so it adds body and a deeper, almost caramelized note once it picks up color in the pot during that first sauté. Canned pumpkin puree is doing something neither vegetable can: it purees into an almost velvety texture on its own, and it stabilizes the whole soup so it stays smooth and doesn't separate after it's frozen and reheated. NYT Cooking's sweet potato and butternut squash soup pairs just the first two for a similar contrast in sweetness and texture, but skips the canned pumpkin altogether, which is where this version ends up creamier without needing more cream.
If you only have two of the three on hand, this still works. Short on sweet potato? Use a bit more squash and rely on the canned pumpkin for the body. Out of squash? More sweet potato will make the soup a little sweeter, so pull back the maple syrup by half. Skipping the canned pumpkin isn't a great trade, though, since it's what keeps the texture from turning grainy once the cream goes in.
If you're after something lighter with a similar one-pot, immersion-blender method, my Creamy Zucchini Soup uses the same technique without any of the fall spices, in case you want a version for a different season.🎃
The Ingredients That Do the Work
Butternut squash and sweet potato are the backbone here, and cubing them small (about a half-inch) means they cook through in under 25 minutes instead of 45.
Pumpkin puree thickens the soup without any flour or cornstarch, so the texture stays smooth rather than starchy.
Maple syrup and butter round out the natural sugars the vegetables release when they caramelize, while thyme, sage, cinnamon, and nutmeg keep the spice profile savory-leaning rather than pie-flavored - this isn't dessert in a bowl, it's dinner that happens to smell like a candle.
A cup of heavy cream stirred in at the end gives the soup its silky finish, and a drizzle of extra cream on top right before serving makes it look like something from a restaurant menu instead of a Tuesday night dinner.
🥄 Two Ways to Serve It
Smooth and velvety: Blend the whole pot with an immersion blender until every trace of vegetable chunk disappears. This is the version that photographs well and spoons up like a bisque.
Rustic with texture: Pull out a cup of the cooked vegetables before blending, then stir them back in once the rest of the soup is smooth. You get pockets of tender squash and sweet potato in every bowl, which is my preference when I'm serving this as a starter rather than the main event.

Recipe Questions
What do I need to make this soup?
Butternut squash, sweet potato, canned pumpkin puree, a yellow onion, garlic, olive oil, broth, heavy cream, maple syrup, butter, and a handful of pantry spices - thyme, sage, cinnamon, and nutmeg. A large Dutch oven and an immersion blender do the rest.
Can I serve this cold?
No - this soup wants to be hot or warm. The cream and pumpkin puree firm up as they cool, so it loses that silky quality if it sits too long off the heat.
Can I make this dairy-free?
Yes. Full-fat coconut milk swaps in for the heavy cream at the same measurement, and it adds a faint coconut note that plays surprisingly well with the sage and nutmeg.
Can I use pre-cut squash and sweet potato?
Absolutely - fresh pre-cut cubes save real prep time, and frozen cubes work too. Add them straight to the pot without thawing.
Whether it's the first cold night of the season or you just need something warm after a long day, ladle this into your favorite bowl, top it with pepitas and croutons, and call it dinner.
