Why Try Soup With Pumpkin and Sweet Potato
Fall is here, and you know what that means-pumpkin everything! While I love my collection of canned pumpkin recipes (like pumpkin cinnamon rolls and easy vegan pumpkin muffins), fresh pumpkin also deserves the spotlight. Trust me, it's worth the extra steps. This soup is a silky (smooth or rustic and chunky!), creamy, and delicious sweet potato pumpkin soup recipe - it's a satisfying hug in a bowl perfect for weeknight dinners, dinner parties, and holiday gatherings.
Roasting the veg really brings out their flavor and adds caramelization. Even better, this sweet potato and pumpkin soup recipe is loaded with nutrients like fiber, antioxidants, and several vitamins/minerals (like vitamins A and C, potassium, iron, etc.). Meanwhile, silken tofu adds creaminess and protein while remaining low in fat and calories. Pro tip: Make a double batch because it makes great leftovers, too!
You can also swap in fresh pumpkin for these butternut squash bean burritos, easy butternut squash enchiladas, or air fry butternut squash recipes! When spring comes around, my potato asparagus soup is a great blended soup to make next. For a protein-packed soup, try my easy yellow split pea soup. For another fall soup, make my vegan French onion soup with bubbly vegan cheese toast.

How to Make Sweet Potato Pumpkin Soue
Keep scrolling to the recipe card for the complete list of ingredients and recipe instructions.
Step 1: Preheat the oven to 400F/200C and line a baking sheet with parchment paper. Meanwhile, peel and wedge the onion and cube the sweet potato and pumpkin into 1-inch pieces. Chop ½-inch off the top of the head of garlic. Transfer the chopped ingredients to the baking sheet, toss with the oil, salt, cumin, and coriander, and mix well to coat evenly.
Step 2: Roast for 30-40 minutes, until tender and the onions/garlic are a little charred. Then, transfer the roasted veggies to a large, lidded pot, placing the head of garlic on a separate plate to cool.
I cut the pumpkin in half, scoop out the seeds with a spoon, peel it, then slice it into 1-inch strips and cut those into 1-inch diced pieces.
Step 3: Add the vegetable stock (I used bouillon cubes + water) to the pot, bring to a boil over high, then lower to a simmer, cover with a lid, and simmer for 30 minutes.
Step 4: Then, blend the silken tofu and garlic (in a blender/food processor) until smooth. Next, use a spoon or masher to lightly mash some of the pumpkin and sweet potato. Then, taste the pumpkin sweet potato soup and adjust the seasoning.
Step 5: Stir in the garlic tofu mix, then serve the roasted sweet potato and pumpkin soup, optionally garnished with fresh thyme and pumpkin seeds - enjoy!
FAQs
Yes, technically, but canned pumpkin misses the added depth that roasting gives it. If you want to try, use 2 15oz cans of pumpkin puree and simmer it for 5-8 minutes to concentrate its flavor first.
Technically, yes, but you won't get all the added flavor depth and enhanced caramelization of roasting them.
Pro Recipe Notes
- Roast properly: The veg should be properly caramelized/ a little charred for maximum flavor. Optionally, broil them at the end.
- Use the best pumpkin: Skip the leftover carving pumpkins. Make sure to use a sugar pie pumpkin or other culinary variety for the best flavor.
- Adjust the consistency/texture: You can blend some or all of the soup and optionally add extra broth for a thinner consistency.
Serving Suggestions
- Bread (Like crusty bread/baguette, a dinner roll, my Garlic Herb Focaccia, or this easy air fryer garlic bread)
- Sandwiches (like vegan tea sandwiches or a vegan grilled cheese)
- Salad (Simple leafy green salads work well)
Storage Instructions
Fridge: Store sweet potato pumpkin soup in an airtight container for 4-5 days. This is the Pyrex bowl with a lid I'm using in the photo below.
Freeze: In freezer-safe bags (spread flat and squeeze out excess air) or airtight containers for up to 3 months. Thaw in the fridge overnight. I use these Stasher bags for freezing. And I absolutely love these Souper Cube freezer molds because they're pre-measured-perfect for meal prepping!
Reheat: On the stove (over medium-low heat) or in a microwave (30-second increments, stirring in between).
