Best Sweet Potato Soup

The first spoonful hits like a warm hug you didn’t know you needed.

I remember the first time I made this sweet potato soup—it was one of those chilly fall evenings where the wind rattles the windows and everything smells like cinnamon and wood smoke. I wanted something cozy, something that could turn a simple dinner into a little celebration of comfort. And wow, this recipe did not disappoint. Creamy, flavorful, and just a touch sweet, it instantly became my go-to for cold nights.

What makes this the best potato soup isn’t just the taste; it’s the texture. Smooth and velvety, with that subtle sweetness from the roasted sweet potatoes, every bite feels indulgent yet wholesome. The aroma fills the kitchen in a way that makes everyone gather around the stove, curious and hungry.

Sweet potatoes aren’t just delicious—they’re versatile. This soup takes advantage of that natural sweetness and pairs it with warming spices like nutmeg and cinnamon, creating one of my favorite fall soup recipes. Even when winter rolls around, I find myself making this again and again because it doubles as a comforting winter soup recipe that warms you from the inside out.

And the best part? It’s deceptively simple. You don’t need fancy ingredients or complicated steps—just a few pantry staples, a little love, and a bit of patience while the flavors develop. By the time you ladle it into bowls, you’ll wonder how something so easy could taste so luxurious.

Ingredient List

For the Soup:

• 2 large sweet potatoes, peeled and diced (about 4 cups)
• 1 medium yellow onion, chopped
• 2 cloves garlic, minced
• 4 cups vegetable or chicken broth
• 1 cup coconut milk (or heavy cream for extra richness)
• 2 tablespoons olive oil or butter
• 1 teaspoon ground cinnamon
• ½ teaspoon ground nutmeg
• Salt and pepper, to taste

For Garnish (Optional):

• Chopped fresh parsley or chives
• Toasted pumpkin seeds
• A drizzle of cream or coconut milk

Ingredient Notes

• Sweet potatoes: I always go for orange-fleshed ones—they’re naturally sweeter and give the soup that gorgeous, rich color.
• Coconut milk vs. cream: Coconut milk keeps it slightly lighter and adds a subtle tropical hint, but heavy cream makes it ultra-luxurious.
• Spices: Don’t skip the cinnamon and nutmeg! They’re small touches that turn this from good to unforgettable.
• Broth: I like using a homemade or high-quality vegetable broth—it deepens the flavor so much.
• Garnish: The toasted pumpkin seeds add a fun crunch that balances the creaminess perfectly.

Kitchen Equipment Needed

• Large pot or Dutch oven: Perfect for cooking the sweet potatoes and letting flavors meld. I love my heavy-bottomed Dutch oven—it heats evenly and prevents sticking.
• Cutting board & sharp knife: For chopping sweet potatoes, onion, and garlic quickly and safely.
• Wooden spoon or silicone spatula: For stirring without scratching your pot.
• Blender or immersion blender: To puree the soup until silky smooth. I personally use an immersion blender—it’s faster and less messy.
• Measuring cups & spoons: For precise seasoning and liquids.
• Ladle: For serving and portioning the soup into bowls effortlessly.

Instructions

1. Prepare the Vegetables

• Peel and dice the sweet potatoes into roughly 1-inch cubes for even cooking.
• Chop the onion and mince the garlic.
  Pro tip: Try to keep the sweet potato pieces uniform so they cook at the same rate—no one likes mushy chunks mixed with firmer ones!

2. Sauté Aromatics

• Heat the olive oil or butter in your large pot over medium heat.
• Add the chopped onion and cook for 5–6 minutes, stirring occasionally, until soft and fragrant.
• Stir in the garlic and cook for another 30 seconds until aromatic.
  Pro tip: Watch the garlic carefully—it burns quickly and can turn bitter.

3. Roast the Sweet Potatoes (Optional but Recommended)

• While the onions sauté, spread the diced sweet potatoes on a baking sheet, drizzle lightly with olive oil, and roast at 400°F (200°C) for 20–25 minutes until tender and slightly caramelized.
  Pro tip: Roasting brings out a natural sweetness that makes your sweet potato soup extra flavorful.

4. Cook the Soup

• Add the roasted sweet potatoes to the pot with the onions and garlic.
• Pour in the vegetable or chicken broth and stir to combine.
• Season with cinnamon, nutmeg, salt, and pepper.
• Bring the mixture to a boil, then reduce the heat and let it simmer for 15–20 minutes so the flavors meld together.

5. Blend Until Smooth

• Use an immersion blender directly in the pot, or transfer the soup in batches to a countertop blender.
• Blend until the soup is completely smooth and creamy.
  Pro tip: If using a countertop blender, remove the center cap to vent steam and cover with a kitchen towel to prevent splatters.

6. Finish with Creaminess

• Stir in the coconut milk or heavy cream until fully incorporated.
• Taste and adjust seasoning if needed—sometimes a pinch more salt or a dash more cinnamon elevates it perfectly.

7. Serve and Garnish

• Ladle the soup into bowls.
• Top with optional garnishes like chopped parsley, toasted pumpkin seeds, or a drizzle of cream for a finishing touch.

Tips and Tricks for Success

• Don’t overcook the sweet potatoes: They should be tender enough to blend easily but not falling apart into mush.
• Blend in batches if needed: Prevents splatters and ensures a smooth texture.
• Adjust the thickness: Add extra broth if you like it thinner, or simmer a little longer for a thicker, heartier soup.
• Season gradually: Start with a little salt and spices, then taste and adjust as the soup simmers.
• Serve warm, not boiling hot: This lets the flavors shine without scalding your tongue.

Ingredient Substitutions and Variations

• Sweet potatoes: You can swap in butternut squash or pumpkin for a slightly different sweetness and texture.
• Coconut milk: Heavy cream, half-and-half, or even cashew cream works beautifully.
• Spices: Try adding a pinch of smoked paprika or curry powder for a twist on the classic flavor.
• Broth: Vegetable broth keeps it vegetarian, but chicken broth adds extra depth.
• Garnishes: Crumbled bacon, crispy croutons, or a sprinkle of Parmesan can turn this into a fun variation for adults.

Serving Suggestions

• I love serving this sweet potato soup with a slice of crusty sourdough bread—it’s perfect for dipping and adds a satisfying crunch.
• Top each bowl with a dollop of Greek yogurt or a swirl of cream for extra richness and a beautiful presentation.
• Pair it with a fresh green salad or roasted vegetables for a balanced meal that’s still cozy and comforting.
• Add a sprinkle of toasted pumpkin seeds or croutons right before serving for texture and a little nutty flavor.
• For a fun twist, serve it alongside a grilled cheese sandwich—the classic combo never fails!

Storage and Reheating Instructions

• Refrigerate: Store the soup in an airtight container for up to 4 days.
• Freeze: It freezes well for up to 3 months—leave a little space at the top of the container for expansion.
• Reheat on stovetop: Warm gently over medium-low heat, stirring occasionally to prevent sticking.
• Reheat in microwave: Cover and heat in 1–2 minute increments, stirring between each, until warmed through.
• Adjust consistency: If the soup thickens too much after storing, stir in a splash of broth or milk to bring it back to the desired texture.

Frequently Asked Questions

Can I make this soup vegan?

Absolutely! Just use vegetable broth and coconut milk instead of cream, and it’s fully plant-based while still creamy and delicious.

Can I use regular potatoes instead of sweet potatoes?

Yes, but the flavor will be a bit different. Regular potatoes make a more savory potato soup, while sweet potatoes give that natural sweetness that makes this one special.

How long does it take to make from start to finish?

From chopping to serving, it usually takes about 45–50 minutes. Roasting the sweet potatoes adds a little extra time but is worth it for the flavor.

Can I make this ahead of time?

Definitely! It stores well in the fridge for up to 4 days and freezes beautifully for up to 3 months. Just reheat gently and adjust the consistency if needed.

Can I add other vegetables or flavors?

Yes! Carrots, butternut squash, or a pinch of smoked paprika or curry powder can add a fun twist. Just blend everything together for a smooth finish.

How can I make it extra creamy?

Use heavy cream or full-fat coconut milk, and make sure to blend until silky smooth. A little swirl of cream or yogurt on top when serving also adds richness.
