Perfect Fall Comfort Soup
I just love this time of year because I enjoy cooking and eating a warm bowl of soup. As soon as the weather gets cooler, this recipe is one of the first on my list, along with vegetable beef soup, minestrone and creamy tomato basil soup.
I have a new found love for sweet potatoes beyond just sweet potato casserole! I’ve been baking sweet potato, making roasted sweet potatoes in the oven and even tried this baked sweet potato fries recipe, but had never used them in a soup.
The end result was so delicious! The sweet potato soup recipe is loaded with flavorful veggies and has a warm, creamy taste plus it can be made in one pot. It’s an amazing comfort food meal on it’s own, or serve it with this fall salad.
Why This Recipe Works
- Quick and easy: Wholesome ingredients come together in one pot in 45 minutes! Simple saute, simmer, and blend into a velvety soup.
- Warm spices: Cinnamon and nutmeg are balanced with savory onion and garlic to transform ordinary soup into a memorable rave worthy meal.
- Rich and creamy: This fall soup is made with both heavy cream and milk for the creamiest texture!
- Holiday worthy: Serve as a warm appetizer on Thanksgiving or Christmas or make it for a weeknight meal. It’s incredible either way!

- Sweet potatoes: The star of the show in this delicious soup. Look for sweet potatoes that are large and firm, with an orange flesh. I recommend peeling them before adding to the soup as the skin can be quite tough and fibrous.
- Aromatics: Chopped onion, celery and garlic (also known as a mirepoix) are sauteed in butter until fragrant and tender to give this sweet potato soup an extra depth of flavor.
- Stock: The base of this soup is made with a simple vegetable stock or vegetable broth. The potatoes cook in the stock and will get perfectly tender and delicious.
- Cream and milk: A combination of heavy whipping cream and milk are added for richness and a creamy texture. I recommend using the full fat versions for the best consistency.
- Spices: Adding in a cinnamon stick and a pinch of nutmeg is the perfect finishing touch to this sweet potato soup and gives it the perfect touch of fall!
Substitutions and Variations
There’s nothing stopping you from playing around with the spices in this recipe to enhance the flavor even more. A sprinkle of curry powder, fresh ginger or paprika would add a fun boost of flavor to the soup. I sometimes add another clove of garlic or some fresh leeks too.
With a few simple swaps, you can also easily turn this vegetarian dish into a dairy-free vegan recipe if preferred. Simply sauté the veggies with olive oil instead of butter and use full fat coconut milk in place of the milk and heavy cream.
How to Make Sweet Potato Soup
This recipe for sweet potato soup is made in one pot in just about an hour. It only requires 15 minutes of prep, with the rest being simmering time on the stove. Super easy!
- Cook the veggies. First, I started by chopping up a white onion, celery stocks, and fresh garlic. Then the prepared vegetables are softened in a large pot with melted butter over medium-high heat.
- Add sweet potatoes and spices. Next, you add the star of the soup, diced sweet potatoes, along with the vegetable stock, ground nutmeg and a cinnamon stick.
- Simmer. Bring the ingredients to a boil over high heat, then let simmer until the sweet potatoes are fork tender, which is about 20 minutes.
- Blend and add cream. Once all the vegetables are cooked and tender, you can use an immersion blender to puree the mixture. I worked in small batches in my high speed blender. After the mixture is pureed, stir in the whipping cream, milk, salt, and pepper to taste. Heat the soup back up on the stove and then ladle into bowls!
You can’t forget the toppings! I like to add a drizzle of cream and garnish with chopped chives and some pepitas (pumpkin seeds) for an added crunch. This soup would also taste delicious topped with cornbread croutons!
- Chopped chives
- Sour cream
- Goat cheese
- Raw pepitas or roasted pumpkin seeds
- Sun dried tomatoes
- Chili flakes or red pepper flakes
- Cornbread croutons
- Full fat dairy. Using full fat whipping cream and milk is what helps make this the most creamy sweet potato soup you’ll ever try with a deliciously rich flavor. For the best results, I don’t recommend using lower fat varieties.
- Consistency. If the soup still seems a little thick after blending, feel free to stir in a little more broth to thin it out to your desired consistency.
- Blending. Using an immersion blender is easiest in my opinion, since you can blend the soup together right in the pot without dirtying up any additional dishes. If you don’t have an immersion blender, a standing blender will absolutely work too – just make sure to work in batches.
Let cool and store in an airtight container in the refrigerator. It will stay fresh in the fridge for up to 3 days.
Yes, you can freeze this sweet potato soup. Soups that contain a cream or milk base can sometimes separate when freezing, so I would just add a little bit of fresh cream when reheating.
If planning on freezing the whole batch, you could also just make the soup without the milk/cream, freeze, then add it in when warming back up.
Sweet potato skin is a bit tough and fibrous with a slightly bitter flavor, which is why I prefer to peel them in this recipe.
You can definitely leave the skins on if you’d like, however it may change the consistency and flavor of the soup.
