Whether you’re hosting a fancy dinner party or having a cozy night at home, this roasted sweet potato soup recipe fits the bill. Roasting the sweet potatoes and onions amps up their already delicious flavors. I also add a splash of orange juice for brightness and and balance for the perfect Fall soup. I know it’s still early Fall, but this soup is basically Thanksgiving in a bowl! Move over pumpkin, sweet potatoes are coming for ya!
In a world filled with heavy cream based soups, this recipe gives you the opportunity to lighten things up while achieving the creamy comforting warm hug effect we all want in a great bowl of soup. That’s not to say that a splash of heavy cream wouldn’t be a great addition to this recipe. The notes section of the recipe has a variety of options to stir in some additional creaminess if that suits your fancy.
When this recipe fell behind in the Instagram poll to my Super Simple White Chicken Chili for last weeks post, those that voted for sweet potato soup, specifically my husband, let me know they didn’t want to wait long for this one! So, without further ado, let’s get into the recipe.
Recipe Evolution
I’ve been making a version of this sweet potato soup for as long as I can remember. I have to give credit to my sister, Emily, for suggesting I roast the potatoes before adding them to the soup. My first reaction was, nope, I don’t want to clean a baking sheet. The original recipe only dirtied one pot. As someone who isn’t fond of doing dishes, I was a little attached to that idea. The more I thought about it (and remembered a baking sheet can be covered with aluminum foil for easy clean-up) I ran out of excuses not to give it a try.
Was adding a dirty baking sheet to the sink worth it? YOU BET! In fact, I can’t imagine this recipe without this step. The added depth of flavor far out weighs spending a little more time at the kitchen sink. Flavor for the win! For even easier clean up, you can line the baking sheet with parchment paper or a silicone baking liner.
Garnishes
The best thing about soups and chilis, in my opinion, is the seemingly endless assortment of garnishes that gives one big pot of soup the ability to become unique bowls tailored to each individual lucky enough to have a taste. Here’s a list of my favorite and recommended garnishes for this soup:
- Bacon or prosciutto – an obvious choice. Bacon or prosciutto will add a salty meaty component while also adding some texture. You can find my hints, tips, and tricks for the perfect bacon bits here.
- Toasted chopped walnuts or pecans – a great way to add texture while keeping the recipe vegetarian or vegan. Add walnuts or pecans to a skillet over medium heat, stirring often, for 2-5 minutes until the color darkens a bit and your kitchen starts to smell of walnuts. Watch carefully, walnuts can go from toasted to burnt quickly! Add a few pinches of salt and pepper to season.
- Toasted pumpkin seeds aka pepitas – add cleaned and dried pumpkin seeds to a skillet and follow the same process above. The pumpkin seeds will start to pop open to tell you they’re ready.
- Bleu cheese crumbles – the funk that bleu cheese is known for plays well with the sweet and savory flavors in this soup.
- Shredded rotisserie chicken meat – a super simple way to add lots of protein
- Crusty bread – saving the best for last. Every bowl of soup needs a piece of warm crusty bread to soak up the last drops of deliciousness from the bottom of the bowl. Sourdough is my favorite bread to enjoy wit this soup.
The featured photo of this soup includes bleu cheese crumbles, crusty bread, and crispy prosciutto. A trifecta, if you ask me!
Keys to success
- You can always add more liquid, but it’s really tough to recover if you add too much. When adding your broth/stock, start with the minimum and then blend up the soup. If you desire a thinner soup, continue to add broth/stock 1 cup at a time and blend until you reach the perfect consistency.
- Just like with liquids, it’s easy to add more salt, but very difficult to take it out. I highly recommend starting with a low sodium or no salt added broth/stock so you can control the seasoning of your soup. This is especially important if you’ll be garnishing with salty nuts or salty bacon. Season, taste, season more if necessary.
- Don’t skip turning the sweet potatoes and red onions half way through the roasting process. The sugar content in the potatoes combined with the maple syrup is likely to burn around the bottom.
- For a more refined fancy soup, peel your sweet potatoes and give extra care to the amount of liquid you’re adding to keep the soup from getting too thin. For a more rustic, nutrient dense soup, save time and skip peeling. Leaving the skins will increase the content of fiber, antioxidants, and nutrients like potassium, manganese, and vitamins A, C, and E. Keeping the skins on will require quite a bit more liquid than a soup prepared with peeled sweet potatoes.

- Large sauce pan OR 3.5 quart dutch oven
- Baking sheet
- Immersion blender or stand blender
- Wooden spoon
- Measuring cups and spoons
- Spatula
Ingredients

- 1 small red onion roughly chopped
- 1/4 cup olive or avocado oil
- 2 tablespoons olive oil
- 1ยฝ teaspoon kosher salt

- 1/4 cup real maple syrup
- 1ยฝ teaspoon dried thyme
- 1ยฝ teaspooon dried ground sage
- 6-8 cups low sodium chicken or vegetable stock or broth
- ยผ cup orange juice
Instructions
- Preheat oven to 400ยฐF
- Add the prepped sweet potatoes and red onion, salt, pepper, 1/4 cup olive or avocado oil, and maple syrup to a bowl and toss until potatoes and onions are evenly coated.
- Line a baking sheet with aluminum foil and evenly spread the potatoes and onions on the baking sheet.
- Bake potatoes and onions for 30 minutes, turning with a spatula 1/2 way through cooking to prevent burning.
- When there are about 5 minutes left in the cooking time for the sweet potatoes and onions, start to heat a large sauce pan or 3.5 quart dutch oven over medium heat and add the remaining 2 tablespoons of oil until you see the oil ripple then add the garlic to the hot oil. Cook until fragrant, stirring frequently to prevent burning.
- Add the roasted sweet potatoes and onions to the garlic followed by the white pepper, dried thyme, and dried ground sage. Stir to evenly coat the sweet potatoes and onions with the seasonings. Continue cooking, stirring occasionally for 5 minutes.
- Add the orange juice and the stock or broth and bring to a boil. Start with 6 cups. Once boiling, reduce to a simmer for approximately 10 minutes.
- Blend soup. See notes.
- Eat immediately, store in the fridge for up to 5 days, or freeze in an air tight container for up to 4 months.
Notes
- If you want a creamier, silkier soup, stir in one of the following after blending when ready to serve.ย Do not add any of these ingredients if you plan to freeze the soup until you’re ready to re-heat and serve.
- 1/2 cup heavy cream
- 1/2 cup greek yogurt
- 1/2 cup crรจme fraiche
- 1/2 cup coconut milk
- 1/4 – 1/2 cup cashew cream – cashew cream will thicken when heated, add slowly, taste and keep an eye on the consistency
- The immersion blender is ideal for this recipe.ย If you use a stand blender remember these tips to prevent you and your kitchen being covered in hot soup:
- Allow soup to cool slightly prior to blending
- Do not fill the blender more than 1/2 way full; blend in batches
- Remove the center plug from the lid and cover the hole with a towel while blending to allow steam to escape.
- The starch content can vary from sweet potato to sweet potato, the more starch the more stock/broth will be needed to create the ideal consistency.ย Start with 6 cups, then add 1/2 cup at a time and blend until the desired consistency is achieved.
- I do not peel the sweet potatoes, this gives the soup more body, but results in a more rustic nutrient dense soup.ย Peel your sweet potatoes for the smoothest, silkiest texture.
- As written, using vegetable stock/broth this recipe is dairy free, gluten free (verify if using store bought stock/broth, there could be hidden gluten), vegan/vegetarian.
- Garnish options are nearly endless, see full blog post for my best suggestions.

Always a favorite of mine! In an attempt to get more good stuff in the kids I added silken tofu to the mix and it worked like a charm. Kids loved it ๐
