What You'll Need for this Recipe
All of the ingredients come together to create layers of flavor. Here's what to add to your grocery list to make my browned butter sweet potato soup.
- Black Pepper
- Bone Broth
- Cayenne Pepper
- Chili Powder
- Olive Oil
- Sea Salt
- Sweet Potatoes
There are a few substitutions that work well in this recipe. You can use onion or scallions in place of the leeks, if needed. I recommend sweet yellow onion to get the closet flavor. And I love bone broth in my soups to add extra protein and nutrients but feel free to use whichever broth or stock you prefer!
Tips & Tools for Making this Soup
Grab a cutting board and a sharp knife to prepare the sweet potatoes, carrots, garlic, leeks, and ginger. Unlike my sweet potato chorizo soup, which has cubed tubers, this fall blender soup comes together in...a blender so you'll need a sturdy one on deck. That's how to make a smooth sweet potato soup without a lot of elbow grease. You can use an immersion blender as well. And I cook the soup down in a dutch oven and serve it with a soup ladle.
Can you eat sweet potato skins in soup? Absolutely! I don't peel my sweet potatoes before adding them in and everything blends up nice and easy. Sweet potato skin is completely safe to eat and actually has fiber and other nutrients.
Can I freeze sweet potato soup? Another yes. Sweet potato soup freezes beautifully and thaws easily in the fridge or on the stovetop. Portion it out into cubes, freeze, then transfer to freezer safe bags. Keeps up to six months.
What does it Taste Like?
This is a savory sweet potato soup recipe for winter or fall but there are some sweet flavor notes from cinnamon and leeks. You'll also taste a touch of smoky spiciness from the cayenne and chili powder, which is both in and on the soup. Buttery, nutty, earthy, and garlicky--flavors galore!
How to Serve this Soup
Before serving, garnish the soup with a drizzle of olive oil and sprinkles of chili powder and cayenne pepper. And I like a little crunch so will typically add pumpkin seeds over top or homemade croutons. A piece of crusty toasted bread is also a wonderful pairing.
Can I Eat Sweet Potato Soup with PCOS?
This is an excellent PCOS friendly soup recipe because there's a balance of protein, fat, fiber, and complex carbohydrates to help keep blood sugar in check. I like to pair it with a salad for a full meal. And healthy hormone ingredients like cinnamon, olive oil, and bone broth provide nutritious boosts. If you want to make my easy sweet potato soup part of managing PCOS, try to use organic ingredients and check labels for additives and extra sugar.

Browned Butter Sweet Potato Soup Recipe
Brown Butter Sweet Potato with Ginger & Leek
- 2 cups chopped leeks
- 6 cloves garlic
- 2-inch knob of ginger
- 3 pounds sweet potatoes
- 4 carrots
- 2 tablespoons butter
- 6 cups bone broth or broth or stock of your choice
- ½ teaspoon cayenne pepper plus more for garnish
- ¼ teaspoon chili powder plus more for garnish
- ¼ teaspoon cinnamon
- sea salt to taste
- black pepper to taste
- olive oil
- Chop leeks, mince garlic, slice ginger, and cut sweet potato and carrots into chunks. Set aside.
- Add butter to a Dutch oven or stock pot over medium heat. Gently stir the butter as it melts. It will sizzle, foam, and turn a deeper color. You should see small bits (the milk solids) at the bottom of the pan that are golden brown. (About three minutes).
- Add leeks, garlic, and ginger to pot with browned butter and allow to cook down until fragrant and tender (about 5 minutes).
- Increase heat to medium high and add prepared sweet potato, carrots, bone broth, cayenne pepper, chili powder, cinnamon, sea salt, black pepper to pot. Bring to a low boil.
- Reduce heat to medium low, cover, and simmer for about 25 minutes or until sweet potato and carrot are tender.
- Transfer solid ingredients and about two cups of liquid to a blender or food processor and pulse until smooth and uniform. You can, alternatively, use an immersion blender for this step.
- Return soup to pot and stir well to incorporate remaining liquid. Serve with sprinkles of chili powder and cayenne pepper and a drizzle of olive oil.
